Would you like to spend $100 to be told the obvious? No?
Didn’t think so. But that’s often what happens when Atlanta homeowners call us for a furnace repair.
Often the “problem” is caused by a minor issue that they could have fixed, saving themselves the cost of the service call.
So if your furnace isn’t working as it should, hold off that service call! Try these 4 simple troubleshooting tasks first. Of course, if they don’t fix your problem, call us for help.
Furnace not coming on? Check the thermostat first and do these tasks:
Now, if the furnace is blowing cool air sometimes, you want to check the thermostat fan setting to make sure it’s on “auto,” not “on.” The “on” setting will cause the blower to run constantly, even if the furnace is not heating the air.
Is your furnace shutting down randomly? Does it run for a long time and never seem to heat the home? Is the air coming out of your vents weak?
You may have a dirty furnace filter.
A dirty furnace filter restricts airflow over the furnace’s heat exchanger, causing several problems:
Your owner’s manual should show you where the furnace filter is and how to replace it. Check the filter at least once a month and change it, if needed.
So when is a filter “too dirty” to keep around? Hold the filter up to the light. If you can’t see light coming through it clearly, replace it.
Does your furnace refuse to turn on no matter what temperature you set it to?
It may be turned off. A few places to check include:
Homeowners often close air vents in unused rooms to save money.
However, closing vents in any rooms actually causes the opposite to happen: it wastes money— and it can cause the furnace to shut down, too!
Well, your furnace is sized to heat your entire home, unused rooms and all. Closing vents does not decrease the amount of air the blower pushes out. It just increases pressure in the air duct system.
(Imagine trying to run while breathing with only one nostril. You’re still trying to move the same amount of air, but now there’s way more pressure traveling through that one nostril.)
This extra pressure in the duct system causes several issues you may be having:
