What is the most common problem with furnaces?

As we navigate through the chilly months, awareness of the performance of your furnace is crucial. To ensure you can fix problems early before they become serious, it is important for you to know the most common problems homeowners encounter with their furnaces.

Frequent Cycling or Erratic Behavior

Your furnace will run when temperatures in your home drop below a certain point, and it will shut off when desired temperatures are reached. But when your furnace is cycling frequently or behaving erratically, there is a problem present. Short cycling or erratic behavior can mean that your thermostat needs recalibration, an incorrect setting, or a clogged filter telling your furnace it’s time to retire early.

Unusual Noises

A furnace should be felt, not heard. So, when it starts to sound like there’s a tiny metal concert happening in your basement or utility closet, it’s a clue that all’s not well. Groans, bangs, or whistles aren’t part of a furnace’s normal repertoire. These noises can be signs of wear and tear, signaling that belts, bearings, or other internal components are reaching the end of their life.

Persistent Pilot Light Issues

If the pilot light won’t stay lit, it can mean there is a faulty thermocouple or an intrusive draft. This can cause your furnace to fail at heating your home during inconvenient times.

Uneven Heating

A house divided by temperature is in turmoil. If your living room feels warm while the bedrooms feel cold, it’s a sign your furnace is distributing warmth unevenly. This may mean your ducts are battling blockages or your furnace is getting older.

Poor Air Quality

If you find yourself sneezing or coughing more often, then you probably have poor indoor air quality. Your furnace is also tasked with filtering out the unseen particles in the air in your home, but when it fails, you’ll find yourself wishing for a breath of fresh air, quite literally.
