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.

Tony and Carlos are awesome in what they do. They did a great job on about 20 different projects for my family and me. They did security lights patio lights front porch lights. Ran all the electrical for our new master bath remodel. Added on some new interior lights and changed out some switches. I have light where there once was darkness. Thanks guys.

Detailed orientated and honest inspection. Chad took his time and explained everything that was going on very well. The service fee was fair for the small issues he fixed, and he was able to make a referral for water restoration for us, I would use his service again and plan to when our water heater goes out.

Fine young man and as far as I am concerned he can be his permanent tech. He was very polite and he was very pleased with him and will be calling us again to work with Manolo. Manolo needs a pat on the back and he did a good job.

I had Kyle U as my plumbing tech. He did a great job and worked really hard to get to the bottom of things (like roots). He was also polite and honest.
