Trouble Shooting Tips for My Furnace/Heating System

Your furnace or heating system can act up from time to time, but do you need professional service for everything? Take a look at some troubleshooting tips for the most common HVAC issues that you can try before calling for backup.

Your Furnace Cycles on and Off Frequently 

If you notice your furnace turns on and off a lot, there are some things to check. First, how’s your air filter? If your filter is dirty or clogged, it makes it hard for your furnace to pull in air, and it has to work overtime to keep up with demand. To do this, it will cycle on and off frequently to try to warm your home. Change or clean your air filter and see if that fixes the issue. 

Your Furnace is Loud

If your heating system is louder than usual, the most common cause is a dirty air filter. Just like with frequent on/off cycling, a dirty filter leads to an overworked furnace that runs louder than usual because it’s trying to pull air in through a bunch of dirt and dust. Changing the filter could help. However, if you notice sounds like shrieking, squealing, or popping, it could be more serious. Call your HVAC company for an inspection. 

Your Furnace Just Keeps Running

A furnace that seems to run all the time could have an issue with the thermostat setting. First, check to see if it’s set to “fan” or “auto.” The fan setting means the fan will be on all the time, making it seem like the furnace is on, even if it’s not blowing warm air. 

Simple troubleshooting could fix your furnace problem. If you’ve tried the steps above and they haven’t solved the problem, it could be time for a professional. Contact G+S Heating and Air to schedule a service call from a licensed technician.
