What to Know About Heater Repair: 5 Common Heating Furnace Problems

When the days get chilly, sitting at home in a cold house can be miserable. If your furnace doesn't seem to heat your home correctly, this could be a big sign that you could need a heater repair.

Your heating system should maintain a comfortable temperature inside your home. If it blows too much but doesn't maintain the temperature, you're wasting energy (and money) while suffering in a cold house. You could also risk your health from carbon monoxide poisoning or breathing in dirty air from a broken furnace.

Keep an eye on your furnace and watch for these five common furnace problems.

1. Furnace Doesn't Ignite

Your heater won't blow warm air without a "lit" pilot light. It's a small flame, but the pilot light has the critical role of lighting the gas from the burner to produce warm air.

If you find your furnace not igniting, approach it with caution to check the pilot light. In some cases, relighting it (with caution) solves the problems. In other instances, you could have a problem with the gas line or a leak.

Start with a smell test. If you smell gas, do not attempt to relight the pilot flame. Contact a heating professional for help.

2. Furnace Doesn't Blow Hot Air

You could need a repair if the furnace turns on but no heat comes through the vent to warm your home. This could be an issue with the pilot light. You could also have a clogged filter or an incorrect thermostat setting.

Confirm that your thermostat setting is "heat," and the temperature is high enough to trigger the furnace to blow. Check the air filter. Replace it if the filter is old or dirty.

If those steps don't trigger heated air when your furnace comes on, it's time to call a heating specialist.

3. Furnace Blower Doesn't Work

If you hear the furnace turn on, but the blower doesn't push air through the vents, try a few things for troubleshooting your furnace blower.

  • Check the breaker to make sure your heater has power
  • Adjust the thermostat temperature setting
  • Set the thermostat to "fan"

If the fan setting doesn't trigger the blower, you might need a repair for the blower motor.

4. Furnace Cycles On and Off

A clogged filter could be the culprit for a furnace that repeatedly cycles on and off. Replace the filter and adjust the thermostat setting to make sure the temperature is not too high. Call your heating professionals if the furnace continues to cycle off and on rapidly.

5. Temperature Is Inconsistent

Is one room colder than the others? Check the vents. A closed or blocked vent won't allow the furnace to circulate air effectively through your home.

Satisfied Customer

Excellent work by all, starting with the ease of making an appointment, the arrival of the service crew in a timely manner. They were on neatly dressed, very pleasant, explained everything and took the little extra steps to make the visit a success. I have used this plumber three times now and have always had exceptional service from them.

My daughter Natalie Permenter actually ordered the service. I'm at her house during the day to keep my grandson. I was very impressed by Emanuel, the plumber that cam. He was very professional and seemed to really care about his clients. Natalie tells me the lady in the office also showed professionalism and a genuine desire to help. Emanuel was disappointed that he couldn't get the job done on day one; but promised to come back the next day. True to his word he was here bright and early. I am so impressed to finally find a company that really cares about the consumer; not just the dollar.
