Although your furnace is expected to serve you faithfully for years, it will probably experience problems at some point. Knowing the top furnace problems you may encounter will help you identify the symptoms and take preventive measures to avoid them. Here’s more on some of the top furnace problems you may face.
Frequent Cycling
Furnaces cycle on and off several times each hour as they work to maintain the set temperature on the thermostat. If your unit turns on and off frequently and never reaches the programmed temperature, a lack of adequate airflow is the likely culprit. A clogged filter may be restricting airflow. Contact an HVAC technician if replacing your air filter doesn’t fix the issue.
Malfunctioning Heat Exchanger
Your furnace pushes air through the heat exchanger, where heated tubes warm the air before it’s pushed into your house. Without maintenance, the heat that the tubes handle can overwhelm them, making them crack or have other problems. When the heat exchanger has a problem, you may notice that the air coming out of the vents isn’t sufficiently warm. You’ll likely need to have the heat exchanger replaced.
Unusual Noises
It’s normal for your furnace to make certain sounds, such as clicking when the thermostat sends a signal to the system after reaching a particular temperature or a whooshing sound as heated air moves through the ductwork. Loud, unexpected noises such as squeaking, rattling, and rumbling may be signs of mechanical issues, a clogged burner, or airflow restriction. An HVAC technician can pinpoint the exact cause of the noises.
Furnace Isn’t Heating At All
When your furnace stops heating your home, you should take a look at the circuit breaker, as that is often the source of one of the top furnace problems. Resetting the breaker if it had tripped should fix the issue. You may also have failed to set the thermostat to “heat” or have set it too low. A problem with the pilot light or electrical ignition may also be to blame.
You can prevent these top furnace problems by changing your air filters regularly, reducing drafts, and scheduling routine maintenance. For the best furnace installation, maintenance, and repairs in the Lorain area, contact Energy 1 Heating & Air Conditioning.
