Our furnace installation service is designed to equip your home with a perfectly matched heating system.

Annual maintenance is the cornerstone of a safe and reliable furnace. Our tune up service is a meticulous process focused on safety and efficiency.

Most Common Furnace Questions

Your furnace is a complex system, and it is natural to have questions about its operation and care. We have answered some of the most common furnace questions from our Chesterfield customers. This information will help you feel more knowledgeable about your home’s heating system.

There are several clear signs that your furnace is in distress and in need of professional repair. One of the most obvious signs is if the furnace is not producing enough heat, or if it is blowing cool air instead of warm air. This can indicate a number of problems, from a simple clogged filter to an issue with the burner or heating element. If you find yourself constantly nudging the thermostat higher to stay comfortable, your furnace is likely struggling to keep up and needs to be inspected.

Unusual noises are another major red flag. While furnaces make some noise during normal operation, loud or sudden sounds like banging, popping, screeching, or rumbling are cause for concern. A banging sound could indicate a problem with delayed ignition in a gas furnace. A high pitched squeal often points to a problem with the blower motor or its belt. Rattling noises could be a sign of a loose panel or a more serious mechanical issue. Ignoring these sounds can lead to more significant and costly damage.

You should also pay close attention to your furnace’s cycling patterns and any unusual smells. A furnace that is turning on and off much more frequently than it used to, a condition called short cycling, is a sign of a problem like overheating or a faulty thermostat. If you smell gas near your unit, you should evacuate and call for emergency service immediately. A strong dusty or burning smell when the furnace first kicks on for the season is normal, but a persistent burning smell could indicate an overheated motor or an electrical problem.

Deciding whether to repair or replace your furnace is a major decision that usually comes down to three key factors: the furnace’s age, the cost of the proposed repair, and its recent repair history. The average lifespan of a furnace is typically between 15 and 20 years. If your furnace is in this age range or older, it is operating on borrowed time. Investing a significant amount of money in a major repair for a system this old is often not a wise financial decision, as other components are likely to fail in the near future.

A good financial benchmark to use is the 50 percent rule. If the cost of a needed repair is 50 percent or more of the cost of a brand new furnace, replacement is almost always the more sensible option. It does not make long term sense to pour a large sum of money into an aging, inefficient system that is out of warranty. That money would be better used as an investment in a new, reliable furnace that comes with our 10 year installation warranty.

Finally, consider the furnace’s recent history and its energy efficiency. If you have had to call for multiple repairs in the past two winters, the system is clearly becoming unreliable. Furthermore, a new furnace will be significantly more energy efficient than one from 15 years ago, with a much higher AFUE (Annual Fuel Utilization Efficiency) rating. The money you save on your monthly heating bills with a new high efficiency furnace can help to offset the initial investment over time. Our technicians will always provide an honest, no pressure assessment of both options.

A heat exchanger is a critical component located inside your gas furnace. It is a metal chamber or a set of tubes where the natural gas is burned to create heat. The air from your home is then blown across the outside surface of this hot metal chamber, which warms the air before it is circulated through your ductwork. The key function of the heat exchanger is to keep the air you breathe completely separate from the toxic combustion gases, like carbon monoxide, which are supposed to be safely vented out of your home.

A crack in the heat exchanger is a physical hole or fracture in this metal barrier. It is an extremely dangerous condition. A crack allows the combustion byproducts, most notably the odorless, colorless, and poisonous carbon monoxide (CO) gas, to leak out of the heat exchanger and mix with your home’s heated air. This contaminated air is then distributed throughout your entire house, creating a serious risk of carbon monoxide poisoning for you and your family. This is why a cracked heat exchanger is considered the most critical failure a furnace can have.

Heat exchangers crack due to the stress of repeated expansion and contraction over many years of heating and cooling cycles. An oversized furnace that short cycles frequently is more prone to this type of failure. During our annual furnace maintenance, a thorough inspection of the heat exchanger is the most important safety check we perform. If a crack is confirmed, the furnace is immediately shut down and tagged as unsafe to operate. At this point, the furnace must be replaced.

There are several reasons why your furnace might be blowing cold air, some of which are simple to check and others that require a professional. The first thing to check is your thermostat. Ensure it is set to “heat” and that the fan setting is on “auto,” not “on.” If the fan is set to “on,” the blower will run continuously, even when the furnace is not actively heating, which will circulate cool air through the vents between heating cycles. This is a very common and easily fixed issue.

If the thermostat settings are correct, the problem could be a lack of fuel or ignition. For a gas furnace, the pilot light could be out, or the electronic ignition system could be failing. A common point of failure is a dirty or faulty flame sensor. This safety device is designed to shut off the gas if it does not detect a flame after ignition. If the sensor is dirty, it cannot “see” the flame and will shut the burners down, causing the blower to circulate unheated air.

Another common cause is the furnace overheating. If your furnace filter is severely clogged, it restricts airflow through the unit. This can cause the furnace to get too hot, and a safety device called the high limit switch will trip, shutting off the burners to prevent damage or a fire. The blower, however, will continue to run to try and cool the unit down, which results in cold air coming from your vents. If you are experiencing this issue, it is best to have a certified technician accurately diagnose and resolve the problem.

Changing your furnace filter regularly is the single most important maintenance task a homeowner can do to keep their HVAC system running properly. A clean filter allows air to flow freely through the system, while a clogged filter forces the system’s blower motor to work much harder, wasting energy and causing unnecessary strain that can lead to premature failure. A dirty filter is the number one cause of furnace breakdowns. The general recommendation for the most common 1 inch disposable filters is to change them every 1 to 3 months.

The exact frequency depends on several factors specific to your home. If you have pets that shed dander and hair, you will likely need to change your filter more frequently, probably closer to every month. The same is true if anyone in your household suffers from allergies or asthma, or if you live in a particularly dusty area or have recently done any remodeling. The best practice is to physically inspect the filter every month. Hold it up to a light; if you cannot see the light through it, it is time to change it, regardless of how long it has been in place.

Some modern HVAC systems use thicker, high efficiency media filters, which are typically 4 to 5 inches thick. These filters have a much larger surface area and are designed to last much longer than standard 1 inch filters. These types of filters usually need to be replaced only once or twice a year, typically every 6 to 12 months. Your HVAC technician can show you what type of filter your system uses and recommend the ideal replacement schedule for your specific home environment.

AFUE stands for Annual Fuel Utilization Efficiency. It is a percentage rating that measures how efficiently a furnace converts the fuel it consumes into usable heat for your home over the course of an entire heating season. For example, a furnace with a 95% AFUE rating means that for every dollar you spend on fuel, 95 cents is converted into useful heat, while the other 5 cents is lost as exhaust up the flue. A higher AFUE rating signifies a more energy efficient furnace, which translates into lower heating bills.

The U.S. Department of Energy sets a minimum AFUE rating for all new furnaces sold. Furnaces are generally categorized into two main types based on their efficiency. Standard efficiency furnaces typically have an AFUE rating of around 80%. This means they lose about 20% of their heat through the chimney or vent. High efficiency furnaces, also known as condensing furnaces, have AFUE ratings of 90% or higher. These units have a second heat exchanger that captures additional heat from the exhaust gases before they are vented, making them much more efficient.

When you are purchasing a new furnace for your Chesterfield home, the AFUE rating is one of the most important factors to consider. While high efficiency furnaces have a higher initial cost, the long term savings on your monthly gas bills can be substantial, often paying back the price difference over the furnace’s lifespan. Our team can help you compare the costs and potential savings of different models, allowing you to choose a furnace that provides the best long term value for your home.

Yes, absolutely. Installing a new, high efficiency furnace can save you a significant amount of money on your monthly heating bills, especially if you are replacing an older, less efficient model. The primary savings come from the difference in AFUE ratings. If you are replacing a furnace from 15 or 20 years ago, it might have an AFUE rating as low as 60% to 70%. Upgrading to a modern high efficiency furnace with a 95% AFUE rating means you will be getting much more heat from every unit of fuel you purchase, which can dramatically lower your gas bills all winter long.

A new furnace also saves money by being more reliable. The money you would have spent on recurring repairs for your old, aging furnace can instead be put toward your new system. A new furnace comes with a strong warranty, including our 10 year installation warranty, which protects you from unexpected repair costs for a decade. This provides not only financial savings but also invaluable peace of mind during the cold winter months.

Furthermore, a new furnace that is properly sized and installed will run more effectively and efficiently. Many older furnaces were oversized for the homes they were in, causing them to short cycle, which wastes energy. A new system that is correctly sized will have longer, more efficient run cycles. In addition, new furnaces often feature modern technology like variable speed blower motors, which use significantly less electricity than older, single speed motors. The combination of higher fuel efficiency and better electrical efficiency leads to substantial savings.

A whistling noise coming from your furnace or ductwork is almost always a sign of an airflow restriction somewhere in the system. The sound you are hearing is air being forced through a space that is too small for the volume that is trying to get through, much like the sound of whistling through your lips. One of the most common causes of this is a severely clogged and dirty furnace filter. When the filter becomes blocked, the system’s blower motor has to work very hard to pull air through it, and the high velocity of the air moving through the small open spaces in the filter can create a loud whistle.

If you replace the filter and the whistling noise persists, the restriction could be elsewhere in the system. It could be caused by blocked or closed air vents in your rooms. Many people mistakenly close the vents in unused rooms, but this can create a pressure imbalance in the ductwork and lead to whistling noises and strain on your system. The noise could also be caused by undersized ductwork that is too small for the amount of air your furnace’s blower is trying to move.

In some cases, the blower motor itself can create a whistling sound if its bearings are beginning to fail. Gaps or leaks in your ductwork can also sometimes create a whistling sound as air escapes. The best way to diagnose the cause of the noise is to have a professional technician inspect your system. They can determine if the issue is a simple fix like a clogged filter or a more complex problem with your ductwork or furnace components.
