The Cost of Fujitsu Halcyon™ Ductless System

fujitsu-hvac-logo   There are certain factors that affect the safety and efficiency of ductless installation. These factors include the unit type, size of the system, the number of zones, and the difficulty in installing the system. It is also important to consider system configuration and electrical panel capacity. Ductless systems offer flexibility, which means you are not limited to a few options when it comes to installation. The usual cost of installation often depends on the configuration of the system, which will drive the cost higher or lower. Keep in mind these factors that will ultimately affect the cost of installation:
  • Unit size
  • Unit type
  • Number of zones/areas
  • Difficulty in installing the unit
  • The capacity of the electrical panel
  • Configuration of the system
Most types of installations will involve three major parts. These are:
  • Indoor Unit (Wall-Mounted Evaporator or Air Handler)
  • Outdoor Condenser
  • Wiring/Cabling, Linesets, and Drain connecting the indoor and outdoor units

How Much Does A Single-Zone Ductless Installation Cost?

A single zone ductless system is the most basic and simplest type of HVAC installation. If this is the type of HVAC system you want for your home, expect to pay from about $3,500-$5,000. A single-zone layout is an ideal option if you need a heating or cooling solution for a sunroom, for example, a new addition, a standalone structure like a pool house, or a room that cannot accommodate ductwork. Single-zone ductless systems also work well for single rooms, attics, garages, and small homes. [maxbutton id="21" text="Learn More About How Ductless Works" ]

How Much Does A Multi-Zone Ductless Installation Cost?

Some homes are better served with a multi-zone ductless system. These are generally homes with wider areas that can be grouped into several zones. The number of units your home may require will depend on its layout. If a multi-zone system has two evaporator units, you can expect the cost of installation to run between $5,000-$8,000. For a more complex system, such as one with four zones, expect around $6,000-$15,000. ductless installation A key benefit of a ductless system is that it allows the addition of indoor units at any time you need them. This means that you can have additional units installed in case you plan to build adjacent spaces that require heating or cooling. If this is a possible direction for you, give Miller Oil Company a call. We can prepare an installation layout that will provide space for zones that may be added from a single outdoor condenser. That way, you can add additional zones when you are ready. You may think that ductless systems tend to be pricey but that is not entirely true. Like all equipment you purchase, ductless HVAC systems are an investment. With their energy efficiency, ductless systems can save more in terms of energy consumption over the long term. Therefore, they pay for themselves in the form of reduced home heating and cooling costs. [maxbutton id="1" text="Call Today: (860) 745-0326" ] energy-efficient home  

What's The Difference Between Ductless HVAC And Central HVAC Systems?

Ductless HVAC systems are far more energy-efficient than central systems, which means you can save more. Ducted systems tend to lose energy, which is not a problem with ductless systems. Systems that rely on ductwork can lose about 30% of the energy consumed on average. From your point of view as a consumer, that is plenty, especially since it adds up. Ducted systems also tend to be more expensive due to the addition and installation of ductwork. It also requires long-term maintenance that can be costly. With a ductless system, you can turn off specific zones when they are not in use and save energy. You can also enjoy payment plans and rebate programs where applicable.

What Is The Difference Between A Boiler And A Furnace?

What Is The Difference Between A Boiler And A Furnace? was originally written and published on Miller Oil Company Blog

image of a dog in front of a radiator Many homeowners are clueless about the differences between a boiler and furnace. It’s hard to blame them especially when both systems are built and designed to provide heating for a home or building. Although they have the same function, the differences are not to be denied. Since you only can choose a furnace vs. boiler, it means that you must figure out those differences. Your choice will depend on your specific heating needs and your home’s current setup. [maxbutton id="2" text="Explore Our Heating Services" ] [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

Differences Between Boilers And Forced-Air Furnaces

In this article, we discuss some of the basic differences between these two types of heating systems.

The Basics Of A Boiler

A boiler is a closed container that houses water or another liquid. The liquid is meant to be heated, the purpose of which is to generate vapor or steam. The boiler is a primary component of a heating system that relies on even heat distribution and emission. The concept of using water or a similar form of liquid for heating is referred to as hydronic heating. It is incorporated in a radiator system. The system is made up of a boiler, radiators, pipe system, baseboard, and a circulator pump. Each component plays an indispensable role in the production of heat and its distribution to the different rooms in a house or building setting. A typical residential boiler system has several components based on the number of rooms that need heat. image of boiler in home  

The Basics Of A Furnace

Unlike the boiler, the furnace uses air to produce heat. The equipment works by distributing the heated air to the different rooms in a house or building. While the boiler is called the radiator system, the furnace goes by the name of ‘forced-air heating system.’ It forces cool air through the heat exchanger for it to be heated. The heated air passes through a series of ducts for distribution. Furnaces come in three types, namely the upflow, downflow, and horizontal. The fuel source includes electricity, oil, gas, or induction. [maxbutton id="1" text="Call Today: (860) 745-0326" ]

What Are The Differences Between A Boiler And A Furnace?

The most notable difference between a boiler and furnace is the way the systems operate. The boiler heats water inside a tank to produce warmth. It will push the hot water through a series of pipes installed all throughout the building or house. The hot water naturally heats the pipes, which in turn generates the required heat to warm each room. The boiler conveniently warms a living space if it produces steam or hot water constantly. On the other hand, the furnace does not use water or liquid to heat a building or house. Instead, it relies on a heat exchanger to heat air. The air is circulated throughout the living space to keep it warm. Heat distribution is carried out by the blower motor that pushes the air through the ductwork and vents. boiler radiator  

The Energy Efficiency Of A Boiler Vs. Furnace

Heating air requires more energy than heating water. In other words, furnaces are expected to consume more fuel within a period compared to boilers. Meanwhile, the purchase price of a boiler is slightly higher compared to a furnace, but it is expected to last longer. But then again, there are other factors that influence the longevity of your heating equipment, including the lack of maintenance.

Boiler Advantages And Disadvantages


  • Efficient: Boilers require less fuel to produce heat, which means that you’ll spend less to get comfortable during the cold months.
  • Less Noise: A boiler doesn’t produce hot air and distribute it throughout a series of ducts. Therefore, you don’t expect it to produce a lot of noise when compared to a furnace.
  • Heat Consistency: Hot water or vapor can produce a more consistent heat compared to heated air.
  • Better Air Quality: Boilers heat water or liquid, not air. As such, they don’t carry with them airborne contaminants like dust, allergens, and pollens.


  • Heat Only Function: Boilers are efficient in heating homes, but that’s about it. The equipment cannot cool it during the summer. Although the furnace only produces heat, the ductwork can be used for the installation of a central cooling system.
  • Installation: A boiler is complicated to install. It typically requires the services of a professional.
  • Slow Time Adjusting to Changes in Temperatures: It will take a considerable amount of time for a boiler to transition the moment there’s a change in the thermostat.
  • Potential for Leakage: Old and damaged boilers become prone to leakages. It’s obviously because of the water or fluid in the tank. The presence of a leak could result in water damage.
  • Difficult Conversion: The switch to a boiler system to a furnace may seem too much of a hill to climb for most property owners. It is because the installation of the ductwork and other components is quite expensive.

Furnace Advantages And Disadvantages


  • Flexible: A furnace is versatile enough to use a handful of fuel sources, including heating oil, propane, natural gas, and electricity. You can also invest in a modern variant powered by geothermal or solar energy.
  • Fast Acting: Furnaces generate heat quicker than boilers. In other words, they can warm up your home within a shorter span of time.
  • Competitive Purchase Price: Furnaces are quite popular in this part of the world, which is why you expect the price of buying one to be competitive because of the competition among manufacturers.
  • Reduced Potential for Leaks: A furnace leak means an air leak, not water. There’s no risk of water damage.
  • No Freezing Hazard: Furnaces are ideal in areas that experience extreme winter temperatures. The reason is that furnaces minimize the risk of frozen pipes. Boilers use water to heat, which is why there’s an increased chance of freezing pipes that could burst.


  • Noisy: Since furnaces use blowers to distribute heater air, you expect them to produce some noise.
  • Heat Consistency Issues: When it comes to consistency, heated air is inferior compared to hot water or steam. Therefore, homes that use a furnace tend to have some rooms warmer or cooler than others.
  • Air Quality: When you ignore the importance of cleaning or replacing air filters, you’ll suffer from poor indoor air quality.

The Pros And Cons Of Ductless Heating And Cooling Systems

The Pros And Cons Of Ductless Heating And Cooling Systems is property of Miller's Oil Delivery and HVAC Blog

advantages of ductless hvac systems It is vital to make your house a comfortable sanctuary for everyone in your family. To live well, you will need a suitable heating and cooling system. Choose the system type according to your preferences. For example, you can go for ductless mini-split instead of a window HVAC system. A ductless system is composed of two parts: an outdoor unit for the condenser and an indoor unit for the evaporator. They are connected through an electric line and refrigerant lines. This system, as its name suggests, doesn't use any ductwork. It is becoming more and more popular in homes across the United States. In this article, we take a look at the ductless pros and cons. [maxbutton id="31" text="Learn More About Fujitsu Ductless Systems" ] [maxbutton id="1" text="Call Today For A Free In-Home Estimate" ]

Ductless HVAC Pros

1. Ductless Offers Ease Of Installation

Homeowners will only have to think about the location of the two separate components, as guided by an HVAC contractor who can determine its most effective placement. The indoor unit usually rests high up on an exterior wall. The rest is much simpler than a conventional forced-air HVAC system installation. Ducts don't have to run through the rest of the house. This makes the installation fast and simple. Instead of accommodating large airways, you will only need a small 3-inch hole for the electric and refrigerant lines. The walls and ceilings of the house can stay intact. You don't need to tear through them just to set a ductless system up.

2. Higher Energy Efficiency With Ductless Mini-Splits

Ducts can extend for long distances in a big house. However, the longer the air has to travel, the bigger the inefficiency. This is not a problem that ductless systems experience. They can save on energy by reducing heat transfers, thus minimizing waste. The house can also be divided into zones wherein one area is cooled while another isn't because of the lack of occupants. With central air, the whole house will be cooled even if there is only one person staying the whole day in his room. It's easy to see how zoning might lower energy expenditure. [maxbutton id="21" text="Explore How Ductless Works" ]

3. Better Indoor Air Quality

indoor air quality and ductless hvac Ducts can get dusty and dirty over time, especially since they are so complex and hard to clean. Harmful microorganisms may start to multiply. The condition of the ducts will negatively affect indoor air quality. Those who have problems with their respiratory system may feel their illness get worse over time. There are ways to remedy this such as periodic professional cleaning and the use of UV lights for disinfection but these will require additional spending. With ductless mini-split systems, these measures are no longer necessary. They also come with impressive advanced filtration systems. Between the filtration system and the lack of ductwork, indoor air quality will be much better. [maxbutton id="25" ]

4. Independent & Zoned Room Control

fujitsu general ductless hvac system When you have central air, the entire house will be pegged at one temperature setting. This leads to many squabbles about things being too hot or too cold. People can have arguments over the thermostat setting. This problem can be completely eliminated with the use of split systems as these have an individual thermostat for each indoor unit. Occupants of each room have the power to set their ideal temperature. The controls for various zones are independent of each other. This allows the system to cater to different needs at the same time. [maxbutton id="31" text="Explore Fujitsu Ductless HVAC Systems" ] [maxbutton id="1" text="Call Today For A Free Consultation" ]

5. Increased Security

Window systems require a sizeable hole to be removed from the wall in order to fit the unit. This is a security risk since the hole may be big enough for a small person to get inside. If intruders remove the unit, then they can have a clear path to the interior. While it may be possible to secure it with metal grills on the outside, this is an additional expense. Ductless systems don't need such a big hole so they do not expose the family to this kind of danger.

6. Ductless Offer Quiet Operation

Window systems contain every part in one unit including the condenser. This can get noisy over time which may affect the quality of sleep and other quiet activities. This is not as much of an issue with split systems as the condenser is located further away from the room, outside the house. The exterior walls should block the sound and allow occupants to enjoy a restful sleep. [maxbutton id="26" text="Explore Common Fujitsu Ductless FAQ's" ]

Ductless Cons

1. Potentially Higher Ductless System Cost

ductless installation No system is perfect. With mini-split systems, you would have to pay more initially to acquire and install the units as compared to simple window HVAC systems. On the other hand, you can save on duct installation compared to central air. The higher energy efficiency of these systems also makes the initial cost worth it in the long run since you won't have to pay as much for your monthly energy bills. [maxbutton id="1" text="Call Today: (860) 745-0326" ]

2. Visually Evident Indoor Air Handler

Window units and ductless systems are similar in being visually evident. The ductless indoor air handler can be readily seen as it is often positioned near the top of the walls. Central air systems, on the other hand, have less obtrusive vents in the walls and ceilings. However, with ductless units, it is possible to hide the indoor unit using well-designed fixtures that allow the air to pass through. There are also ceiling-mounted units that are less obvious for those concerned about aesthetics.

Furnace Troubleshooting Tips For Every Homeowner

Furnace Troubleshooting Tips For Every Homeowner is property of Miller Oil

house with scarf depicting home heating   Furnaces are designed and built tough to last. However, just like any other machine, they can still malfunction. When this happens, it can disrupt your home’s safety and comfort. It is not recommended to address every issue your furnace has with a do-it-yourself solution. But it doesn’t hurt to know a few furnace troubleshooting methods you can try doing. [maxbutton id="18" text="Explore Our Furnace Services" ] [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

Furnace Troubleshooting Tips For Every Homeowner

Below, we discuss some of the common furnace problems that homeowners encounter. We also share troubleshooting tips that can help:

Lack Of Furnace Maintenance

A furnace that does not receive routine maintenance checks is more likely to break down. This is due to the component wear and tear, and other damages that might happen to it as time passes. Regular furnace troubleshooting and tune-ups are relatively simple. The latter is conducted annually by an HVAC professional who can also perform repairs when needed. This way, small issues are addressed immediately. Do not wait until your heating unit incurs serious damage. The damage might be so severe by then that costs for repair will skyrocket, or it might need to be replaced instead. Troubleshoot: Have a certified HVAC technician conduct furnace maintenance at least once a year. [maxbutton id="1" text="Call Today: (860) 745-0326" ]

Clogged Furnace Filter

Air filters make sure that dust, dirt, and other debris are not circulated along with the conditioned air throughout your house. This way, the air you breathe in is clean and safe. When you are troubleshooting a heating system, one of the usual problems you will encounter is a dirty filter. This is because the dust and other particles accumulate in the filter. As time passes, your filter will become blocked with dirt and won’t work as efficiently. Troubleshoot: Check the furnace air filter at least once a month. A dirty filter should be cleaned or replaced as needed.

Issues With Electric Ignition Or Pilot Control

Electric ignition issues are most likely due to an electrical problem. When a furnace has a pilot that is out, it means the furnace cannot heat your home. Do not light your furnace manually if it utilizes an electronic igniter. Refer to the owner's manual to re-light the furnace, but only if it has power. Troubleshoot: If the electric pilot is out, it might be because the circuit breaker tripped. Fix this problem and recheck the furnace. Check if there are any drafts and clogs as well. Contact a certified HVAC technician if the unit still isn't re-lighting. [maxbutton id="18" text="Learn More About Our Furnace Repair & Replacement Services" ] [maxbutton id="1" text="Call To Make An Appointment" ]

Faulty Thermostat

If you turn on your furnace via the thermostat, but the unit is not responding, it might be because your thermostat is malfunctioning. Troubleshooting is a relatively easy and inexpensive job unless the thermostat needs to be replaced. You can also try changing the batteries with new ones if the thermostat switches on but does not display temperature readings. Troubleshoot: Reset the thermostat. Do this by switching the furnace on and off, or turning off the power to the system completely. Make sure that the batteries aren’t drained by changing them every so often. If these do not work, contact a professional HVAC contractor to check the unit. Thermostat  

Furnace Produces Cold Air

A few reasons your furnace is producing cold air are a clogged filter, incorrect temperature setting, fuel or power shortage, and unlit pilot light. The furnace might also be the wrong size and, therefore, cannot heat the zone it is supposed to. Troubleshoot: Ensure that the furnace size is correct by contacting an HVAC technician. A too-small unit needs to be replaced with a correctly sized one. You should also clean or replace the filter, see to it that the thermostat has the correct setting and that the unit has enough oil and is receiving power. Make sure that the pilot light is working as well. [maxbutton id="18" text="Explore Our Home Furnace Services" ]

Frequent Short Cycling

Furnace short cycling is when your furnace turns on and off repeatedly in short intervals. This malfunction is noticeable as your unit will have quick and consistent bursts of activity. Short cycling can be caused by several reasons. These include overheating, blocked air filters, incorrect sizing, or wrong temperature readings. Troubleshoot: Make sure that the thermostat is working correctly. You should also ensure that it is neither receiving direct light from the sun; nor should it be near any external heat source such as a stove. If it is, then it will likely show you an incorrect temperature reading. Contact a licensed HVAC technician to check if you have the right furnace size for your home. Also, if the heat exchanger is damaged, call an HVAC professional immediately. gas furance  

Furnace Fan Continuously Runs

A furnace fan should only run in the middle of a heating cycle. If it does not stop running even if your unit is not heating, then there might be an issue with the limit switch. The fan limit switch can be switched off manually in some models. Check the manual or the automatic position to see if the same applies to your unit. If it is, follow the instructions and make the correct adjustments on your furnace. Troubleshoot: Set the limit switch to AUTO to stop the fan from running continuously. If you have a malfunctioning limit switch, call your local HVAC technician to take a look at your furnace. [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

Furnace Releases Strange Noise Or Smells

Although you expect a certain level of noise from your furnace, there are a few sounds that should not be ignored. Booming, clanging, clicking, and screeching sounds can be signs of trouble. A unit that is emitting an unusual scent can also mean that there might be an issue. Troubleshoot: Check the air filters and other possible airflow clogs. If it has a blocked burner or if the unit is experiencing mechanical issues, do not attempt a DIY furnace repair. Get in touch with a professional HVAC technician instead.

What To Do When You Have A Cracked Heat Exchanger

The following article What To Do When You Have A Cracked Heat Exchanger was first published to Miller Oil Company News

image of a gas furnace Proper care and maintenance are always recommended for your home heating system to ensure that it is in tiptop shop. It helps avoid issues such as a cracked heat exchanger. There are a couple of telltale signs to look out for if you suspect that your heating system is experiencing this problem. It is, therefore, vital that you learn about the heat exchanger, its importance, and how to determine if you are dealing with a cracked heat exchanger. [maxbutton id="18" text="Explore Our Furnace Services" ] [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

What Is A Heat Exchanger?

The heat exchanger is responsible for transferring heat between fluids for cooling or heating your home or office. The heat exchanger in your home heater works by heating the air that travels through the ventilation system. It is a process that begins when combustible gas increases the temperature in the heat exchanger. In turn, the air in the house increases as well. Therefore, having a cracked heat exchanger will affect how your heater works.

Signs Your Furnace Has A Cracked Heat Exchanger

Listed below are a few of the signs to look out for is you think your heating system might have a cracked heat exchanger:

A Change In The Furnace Flame’s Color

A properly functioning gas furnace has a consistently blue flame. Check to see if this is the case in your furnace. If the fire appears yellow, this could mean that the burner needs to be cleaned. It is also an indication that the furnace has a cracked heat exchanger. The flame should also be burning steadily as a flickering flame means that there is a problem with your heating equipment. [maxbutton id="1" text="Call Today: (860) 745-0326" ] soot  


Soot is the black, powdery byproduct of carbon buildup. It can be found in the furnace's interior. The carbon buildup is because the furnace is unable to burn the gas wholly and cleanly. This can be caused by one of two things: an improperly adjusted burner or a cracked heat exchanger.

Your Furnace Produces Strange Odors

One of the most distinct signs of a cracked heat exchanger is the formaldehyde-like smell. This unpleasant odor causes health issues and gives you severe headaches. If you smell a strange odor coming from your heat exchanger, contact a professional HVAC technician immediately. woman plugging nose from bad furnace odors  

Rust And Cracks On Your Heating System

Physical signs in your furnace include corrosion and cracks in its exterior. If your heating system is showing signs of damage in its external components, the internal parts are likely damaged as well.

Health Issues

Furnace carbon monoxide results in health issues. If you are experiencing symptoms like nausea, eye irritation, drowsiness, disorientation, and other problems similar to flu while you are at home, then it can be because your cracked heat exchanger is releasing carbon monoxide. You must call a professional immediately and have your furnace checked. [maxbutton id="18" text="Learn More About Our Furnace Repair & Replacement Services" ] [maxbutton id="1" text="Call To Make An Appointment" ]

Reasons Heat Exchangers Crack

Overheating is one of the most common reasons heat exchangers crack. It is a result of insufficient airflow in your furnace. The heating system accumulates dust, dirt, and other debris as time passes. When it is not maintained, these pollutants will eventually block the filters and clog the coils and blowers. Proper airflow is needed to keep the temperature inside your heating system leveled and to absorb excess heat. But when the airflow is blocked, the internal temperature will increase and will most likely cause the heat exchanger to crack. Another reason for a cracked heat exchanger is having worn out valves. This issue causes pressure changes that the heat exchanger cannot handle. It is, therefore, vital that you have your heat exchanger regularly maintained so that potential problems are addressed before they get worse. carbon monoxide  

The Problem With A Cracked Heat Exchanger

Issues brought about by a cracked heat exchanger bring inconveniences to you as a homeowner. However, it also poses a serious threat to you and your family's safety as well. Many heating systems are powered by fuel oil, propane, or natural gas. These fossil fuels, unfortunately, produce fumes, which have soot, carbon dioxide, water vapor, and carbon monoxide. These are released into your home when these fuels are burned, and your furnace has a cracked heat exchanger. You and your family can suffer from serious health issues should this happen.

Solutions For A Cracked Heat Exchanger

Never attempt to do a do-it-yourself inspection and/or repair to a cracked heat exchanger. Your malfunctioning heating system might either need to be fitted with a new heat exchanger or be replaced altogether. Call a professional HVAC technician to conduct an inspection and determine the problem. A professional will be able to provide you with the best solution and guide you on how to care for your heating system. [maxbutton id="18" text="Explore Our Home Furnace Services" ]


A cracked heat exchanger not only damages your heating system. It also poses a serious health risk to your household. Fortunately, this issue is preventable. Proper care and regular tune-ups will ensure that your heating system can provide you with adequate heat for a very long time. If you have any concerns with your equipment, make sure to call your local heating technician so you can have solutions as quickly as possible.

Common Furnace FAQs

The following blog post, Common Furnace FAQs, is courtesy of Miller Oil

[WP-Coder id="1"] image of a furnace inspection by a furnace technician As winter draws in, temperatures throughout the country begin to drop. It is advisable, during this time that homeowners check their furnaces to ensure that they are in good working order for the coming Winter months. If any faults are evident or if in doubt, a maintenance check should be scheduled by a home heating expert. Calling in a professional is best done early to avoid waiting times should your furnace stop working when most needed. If left too late it may prove difficult to find the appropriate HVAC services when the cold weather has already arrived. As a homeowner, you may be unsure which services you need. You may have questions regarding the type of maintenance required for your furnace. Is maintenance necessary or is a replacement furnace in order? A qualified HVAC contractor will be able to provide those answers on inspection. However, we will cover some of the most common homeowner's furnace FAQ below: [maxbutton id="18" text="Explore Our Furnace Services" ] [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

Is Furnace Maintenance Absolutely Necessary?

YES. To stay under warranty, it is typical for manufacturers to request proof of maintenance should a need arise for replacement or repair. Also, regular furnace maintenance ensures that your furnace operates safely and efficiently. An annual furnace tune-up helps reduce home heating costs, unnecessary repairs, and improve comfort.

When Is The Best Time To Schedule Furnace Repairs?

It is good practice to schedule a repair as soon as you notice an issue with your furnace. With time, furnace issues tend to increase. Therefore, if you procrastinate, this gives the issue the opportunity to escalate which will increase the severity of the problem and the furnace repair costs. image of a man dealing with a broken furnace  

When Should I Schedule A Furnace Replacement?

This question depends on the furnace. A correctly maintained furnace should operate for over ten years. The longevity of your unit depends on the make and model and how well it is maintained. If your unit is over a decade and breaks down frequently, it is time for a replacement.

What Are Furnace Replacement Signs?

Many signals indicate a furnace replacement is due. These include a delayed ignition, pilot light failure, unpleasant smells/noises, corrosion, and reduced heat output. A reduction of the furnace's efficiency in the form of more costly heating bills and an increase of repairs are also signs for a replacement.

How Often Should I Replace My Furnace Filters?

Most units have an HVAC air filter that prevents the accumulation of dust and dirt inside the system. These filters are essential for protecting indoor air quality. As with any filter, the surface will gradually become clogged up. Therefore, regular replacement is necessary. Check it monthly and replace it when necessary. [maxbutton id="1" text="Call Today: (860) 745-0326" ]

What Is The Best Type Of Furnace?

The right type of furnace is the one that provides the best heat capacity to adequately warm the entire house. An AFUE rating above 80% is advisable. The higher the AFUE rating, the less it will cost to operate. In the U.S., most furnaces already provide ratings above this percentage.

How Can I Reduce My Home Heating Bill?

Home heating is one of the most costly expenses for many people. Regular furnace maintenance is one way of reducing your heating costs. A furnace that is operating at it's best uses less fuel and is more efficient, which, makes it less costly to operate. Slightly lowering your thermostat can also reduce costs. image of a man who has high home heating costs  

How Do I Determine The Size, Or Capacity, Of A Furnace For My Home?

When finding the furnace size for your home, many factors must be taken into account including square footage, ceiling height, orientation, insulation, local climate, and more. You can hire a qualified HVAC contractor to perform a Manual J load calculation to find the best size to meet your heating needs.

What Is The Average Lifespan Of A Newly Installed Furnace?

A new installation should last over two decades with correct care and maintenance. This varies from unit to another. The size of your home is also a factor and should match the unit. Your HVAC contractor will be able to advise you on the size required for your home. [maxbutton id="18" text="Learn More About Our Furnace Repair & Replacement Services" ] [maxbutton id="1" text="Call To Schedule A Free Consultation" ]

What Is A Furnace’s AFUE Rating?

AFUE stands for Annual Fuel Utilization Efficiency. It measures the ratio between fuel consumption and the heat output of a furnace. The standard rating is above 80% but greater than 90% is ideal. Your furnace's user manual should provide the unit's rating or you can find it on the face-plate.


The lifespan of a well-maintained furnace can exceed two decades, meaning most homeowners will only need to replace their furnace a few times during their lifetime. However, to get the best longevity from your home furnace requires knowledge of how to keep it in good working order. Monthly checks on air filters will help keep your system running smoothly as well as scheduling yearly maintenance checks from a furnace professional. In the long run, maintenance is essential, replacement furnaces are costly and a poorly maintained furnace will not last as long as it otherwise could. Likewise for homeowners who have an older furnace in their home, investing in a new furnace can be very beneficial. Not only will it be more efficient, saving money on home heating bills but it will also reduce the need to pay for frequent repairs when an older system is performing poorly.

Understanding Your Residential Boiler

See more on: Miller Oil Company Articles

image of boiler in home Many people count on their residential boiler to ensure their home stays warm throughout the long cold winter. However, have you ever worried about what would happen if you started seeing signs of trouble with your boiler? The big question is often whether you should get it fixed or take the plunge and buy a new boiler. Here we will take a look at the options you have available. [maxbutton id="18" text="Explore Our Boiler Services" ] [maxbutton id="1" text="Call To Schedule A Free, In-Home Estimate" ]

Some Common Problems You Could Encounter With A Residential Boiler

The Boiler Turns Off On Its Own

If your boiler turns itself off, it could be caused by a variety of reasons. For example, there could be a condensate pipe that is frozen. Perhaps, it's a faulty pump, low water pressure, an issue with the air pressure. It could even be a problem with your thermostat.

The Pilot Light Is Out

If your boiler's pilot light goes out, the problem might be a faulty thermocouple or seals that are damaged. Never attempt to repair the pilot light yourself. This is a boiler repair issue that should be left for a licensed HVAC contractor. [maxbutton id="1" text="Call Today: (860) 745-0326" ]

The Boiler Is Leaking

A boiler that is leaking might be because of loose connections or there could be damaged components. In order to be safe, contact a reputable HVAC company to ensure the boiler is repaired properly.

Low Pressure

A boiler that utilizes a pressurized system might lose pressure due to a water leak or problems with the expansion vessel. You might be tempted to repair your residential boiler by yourself with the instruction manual. However, it is much safer to rely on a professional HVAC company for these repairs.

When It's Time For A Replacement Boiler

Below, we will discuss when to repair vs. replace your boiler.

Boiler Age

As your boiler ages, it works harder to warm your home. The average lifespan of a residential boiler is approximately 15 years. It's typical to begin seeing signs of age once the boiler is approaching the 15-year mark.

Reduced Boiler Efficiency

In addition to age, a boiler can become less efficient if it is damaged or neglected. A boiler with low efficiency will need to work much harder to produce sufficient heat to ensure your home stays comfortable. This means you'll likely pay more money for energy costs than what would be needed for a high-efficiency boiler. [maxbutton id="18" text="Learn More About Our Boiler Repair & Replacement Services" ] [maxbutton id="1" text="Call To Schedule A Free Consultation" ]

Hot And Cold Patches

Radiators with warm or cold patches probably have a build-up of sludge in them or there could be trapped air. These problems result in heat distribution that is unequal.

Strange Boiler Noises

Your boiler system should not make gurgling, banging, or whistling noises. If you notice that the boiler is starting to make odd noises, it's time to call in a company that specializes in diagnosing and repairing residential boilers.

Too Many HVAC Repairs

If repairing your boiler is going to cost you half or more as it would cost to have a new boiler installed, then it's time to consider replacing the boiler. Additionally, if you find that you're calling for boiler repairs several times each year, you might want to begin shopping for a new boiler as soon as possible. It can be a smart investment to spend your money on a brand-new boiler system rather than continue dumping money into repairing an old boiler that is reaching the end of its lifespan.

What Are The Advantages And Features of A Residential Boiler Replacement?

If you're trying to decide between getting repairs vs. replacing your boiler, consider the benefits that a new boiler can provide.
  • Increased Comfort: When the coldest days of winter hit, a new boiler can ensure that your home stays warm and comfortable. You'll have the peace of mind in knowing that your home's new boiler will provide the warmth you need even during winter's worst weather.
  • Lower Energy Costs: A new high-efficiency boiler will use far less energy than an older boiler system. It also makes more efficient use of fuel, so you'll be able to keep your home warm for much less money.
  • Lower Costs For Operation: A residential boiler that is new has new components that will be able to function without problems for many years. This means that you'll save money on boiler repairs and checkups.
  • Warranty: A new boiler will come with an equipment warranty that provides coverage for repairs and parts. You'll have the assurance of exceptional service if problems arise.

Homeowners Should Consider The Following Before Buying A New Residential Boiler

  • Size: Purchase the right size boiler. If the boiler is too big, you'll be using more fuel than necessary. If it is not big enough, it won't be able to efficiently heat your home. The boiler size matters and should be determined by evaluating things such as the orientation of the home, the foundation, wall thickness, insulation values, and more.
  • Energy Efficiency: A company that specializes in boiler installations will be happy to recommend a reliable high-efficiency boiler system for your home. An energy-efficient boiler will use less fuel while still providing excellent heating capability.
  • Fuel Type: It's important to choose a boiler that utilizes the type of fuel your home has available, whether it's oil or natural gas.
  • Brand: There are some brands that have worked hard to build a reputation for reliability and exceptional performance. They might also provide better service for your particular area.
  • Warranty: The boiler manufacturer will typically offer a guarantee period or warranty, often providing coverage for replacement parts up to 10 years.

High-Efficiency Vs. Standard-Efficiency Boilers: How Do They Differ?

Boiler efficiency (AFUE) is simply the ratio of heat the unit produces compared with the amount of fuel the system uses. A boiler that is rated as high-efficiency has been designed to cool gases in the flue so that the steam will condense back to a liquid. This helps the system retain heat for better heat production. On the flip side, a boiler rated as standard-efficiency can lose as much as 20% of the heat produced by the boiler. This means your boiler will need to use more energy in order to keep your home warm. A high-efficiency boiler will certainly cost more initially, but it will pay for itself with lower energy costs. Therefore, an energy-efficient boiler offers a great investment for your home's comfort.
