Once furnace repair is complete, you can take steps to avoid any further issues. In this post, we're going to look at some common furnace problems and how to avoid them. Keep reading and learn how to stay warm this winter!

1.) Not Enough Heat

If your furnace isn't producing enough heat, it could be the result of a few different issues. The most common and easiest to fix is a clogged air filter. Filters prevent dirt and debris from getting into the furnace, but when they aren't cleaned or replaced on a regular basis, they become clogged and restrict airflow. It could also be an issue with your thermostat. If you're unsure of how to change a filter or you don't think the filter is to blame, it's best to contact a professional to inspect your furnace.

2.) Pilot Light is Out

Different types of furnaces experience different pilot light issues, but the most common ones have to do with the thermocouple, the safety switch, or the clogging of the pilot orifice. It's always good to clean the pilot light orifice on a regular basis to avoid this problem. Before attempting to reignite the pilot light, make sure you turn off the gas supply to the furnace and leave it for several minutes in case there's a gas buildup. Follow the manual to reignite the flame, but if you're uncomfortable, don't hesitate to contact us.

3.) Furnace is Making Noises

Furnaces make an unmistakable noise when they launch a heating cycle. However, if you hear grinding, scraping, or squealing, you've got a problem.

  • Grinding and scraping usually mean that the ball bearings in your furnace are worn out.

  • Squealing indicates a worn-out blower belt.

The easiest thing to do in both situations is to contact a technician to inspect and replace components for you.

4.) Heat Exchanger Problems

A cracked heat exchanger can leave you vulnerable to harmful carbon monoxide poisoning. This illustrates the importance of regular furnace inspections. If your heat exchanger is cracked, you may first notice water on the floor around the unit or soot inside of it. When the crack is bad, you may notice unpleasant odors, which are the gases entering the air in your home.

5.) Blower Always Running

Once your thermostat gets to the right temperature, the furnace is supposed to stop blowing until it needs to produce heat again. The first thing to do is make sure that the furnace is set to "auto" and not "on". It could also be the fan limit switch being set to "override". If everything looks right, then the limit switch could be faulty or there could be a problem with the wiring to the thermostat. Both problems need a professional touch.
