Why Your Furnace Just Isn’t Getting the Job Done

cold-sweater-manIt’s frustrating to have your furnace running during the winter, and yet still fell the nip of the cold around your home. If this a new experience—the furnace has always done the heating job you need before—then you may need heater repair in Marlton, NJ. You might even need a new furnace!

But let’s not jump ahead. We’re going to go down a list of reasons the furnace may not be providing the heat level you want or is unevenly heating the house. But please, don’t ignore the problem and instead push the thermostat up higher to try to compensate for the heating loss. The issue has to be solved at the source, or you may end up with a completely busted furnace, enormous high heating bills, or even a hazardous heater!

The furnace filter is clogged

We always recommend checking this first when you have an under-performing furnace. The filter isn’t an indoor air quality filter; it’s in place to protect the interior of the furnace from dust and lint coming through the return air ducts. After 1–3 months of operation, the furnace will have a filter clogged up, and this will restrict its ability to send enough air around the house. Change the filter for a clean one to see if this improve the situation. (And remember to change the filter every 1–3 months going forward.)

The thermostat is miscalibrated

This is a common problem: if the thermostat starts reading incorrect temperatures in your house, it will shut the furnace off before it reaches the level you want. Fortunately, this is an easy problem for technicians to correct.

The furnace is short-cycling

Short-cycling is when a furnace is turning on and off rapidly, running for only about 10 minutes and then starting back up again. This gives the furnace much less time to bring the heat up to your desired level. There are many potential reasons for this to happen, and you’ll need a professional HVAC technician to get to the bottom of it so it can be repaired correctly. Allowing a furnace to continue to short-cycle wears the unit down and wastes money.

The air in your house is too dry

The problem may not actually be the furnace at all. Your home may have much drier air than before. Dry air makes cold temperature feel colder because it allows heat to escape from people’s bodies faster. (This is why dry conditions feel better on hot days.) If your house is suffering from dry air, we recommend installing a whole-house humidifier, which can make you feel 8°F warmer on average.

The furnace is too old

Unfortunately, if the furnace has been in service for 15 years or more, it may simply be too old to handle its former workload. Your expert technician can tell you if it’s time to retire the furnace for a new one. You can start taking advantage of the much higher energy efficiency ratings of newer furnaces.
