What to Know About Heater Repairs: The 5 Most Common Heating Problems

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 your eye on your furnace to identify these five common issues:

1. Heating System Doesn't Ignite

Your heating unit won't blow warm air without a "lit" pilot burner. While it is a tiny flame, the pilot burner has the important role of lighting the gas from the burner to generate warm air.

If you realize your heating system is not igniting, approach it with caution to check the pilot lit. Sometimes, relighting it (with caution) will solve the problem. In other circumstances, you may have more serious issues that need remediation.

Start with a smell test. If you smell gas, do not try to relight the pilot fire. Call your local San Diego heating professional.

2. Heater Does Not Blow Warm Air

You know if your furnace is not working, if you turn it on and warm air does not blow. This might be an issue with the pilot burner. In addition, you may have a blocked filter or a wrong thermostat setting.

Ensure that your thermostat is set to "heat," and the temperature level is high enough to activate the heating system. Check the air filter. You will want to change it if the filter is old or dirty.

If those steps do not set off warmed air when your heating system comes on, it's time to call a home heating professional.

3. Blower is not Functional

If you listen closely to your furnace "when it is on", and you do not hear air blowing through the vents, you may have an issue. Do the following test to troubleshoot

  • Check the breaker to ensure the heater has power
  • Readjust the thermostat temperature level
  • Your thermostat fan should be set

If the fan setup does not trigger the blower, you may require repair work 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 North County San Diego 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.

We had to have someone come out today due to a sink and toilet leak. Swayze McLauglin was our plumber and he did a great job explaining the problem and how we could get it fixed. He was great at explaining price as well as what he was doing. Swayze was friendly and professional while he was here as well as working in these trying times with COVID-19 he followed all procedures and was great. We will be using yall the next time we need someone. Thank you so much Swayze for all your help!

Satisfied Customer

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.

Had a plumbing issue on a Sunday afternoon. Joey came out and got the problem resolved. He was very courteous, professional and knew exactly what to do.

Satisfied Customer

I really appreciated Manolos attitude and the way he had patience for all of my questions and never seemed like he was rushing or annoyed with me. He took the time to reexplain it to my husband when he got home. I didn't feel pressured into spending more money or like he was trying to just sell me stuff. I felt like he really took his time and that I was his priority. Thank you for having great service.

Satisfied Customer

Very knowledgeable, friendly and awesome work. Highly recommend this crew for any plumbing needs.
