Gas Furnace problems are a common occurrence this time of year. Some furnace fixes you may be able to do yourself, while others you might need to call in a specialist. In this article we’ll go over some of the more common problems you could encounter with your gas furnace.

Lack of Maintenance

As any professional HVAC technician will tell you, a lack of maintenance on your equipment is going to quickly diminish the efficiency of your furnace. There are a number of things that can affect your furnace from neglect, such as dirty filters and obstructions in furnace area.

Although it might seem like common sense, this is often overlooked. People get busy and don’t realize the issues they could be creating by allowing clutter to pile up around the furnace area. With clutter comes dust, and with dust comes a dirty air filter. After reading this article, if you find yourself removing the clutter around your furnace, be sure to vacuum around it regularly as well!

Furnace Is Blowing Cold Air

There could be many deeper problems to why your furnace isn’t producing heat, but one of the most common reasons could be that you simply need to reset your circuit breaker. After you’ve reset your circuit ensure that your thermostat is set to at least 5 degrees above room temperature. This part might sound silly, but also check that your thermostat is set to heat instead of cool. You’d be surprised how many people overlook this!

Furnace Isn’t Producing Enough Heat

If you feel the air coming out has some heat, but it’s an insufficient amount, it’s very possible your filter is dirty. Replacing the air filter, while being the easiest maintenance chore, is also a quite inexpensive fix.

Replacing your furnace filter is a quick task that we can help guide you through.

  • Locate your filter – On some furnaces the filter is located on the intake. The ones located in a intake will look similar to a grate, typically on the wall, ceiling, or floor. Other filters are located on the furnace itself.
  • Check your filter – To can find out if your filter needs to be changed by holding it up to a light. If you can’t see any light shining through, it’s a sure sign it needs changed. Another dead giveaway is the smell of dust each time your heater turns on.
  • Replace your filter – Before replacing your filter, be sure to turn your furnace off! There shouldn’t be any air coming out. Filters are made to trap dust and other dibres flowing through only one side, so be sure to insert it in the right direction.

Note: If you’re using a used filter, ensure that it’s clean and in good condition.

Debris In The Burner Flames

A quick look at the flames will give you the answer to whether your burners need to be cleaned or not. A clear blue flame means they are burning clean and free of debris. If the flames are burning with a lot of yellow color in the flame, it’s time for a cleaning! Opening the furnace and using a shop vac to clean out the debris should do the trick. Be sure to turn off your gas and furnace and allow time for it to cool off before cleaning.

After you’ve done some troubleshooting and still haven’t found the issue with your furnace, be sure to contact an HVAC contractor. Regardless of a furnaces age, there are possible safety hazards guarding gas-related technical issues. The analysis of an expert will provide the best course of action to take in getting your furnace up and running correctly.
