Your furnace produces a flame that generates the heat necessary to keep your home warm. If there is something wrong with the flame, your HVAC might not function properly. Therefore, you may need to inspect the furnace flame and troubleshoot it.
Inspect the Flame
Make sure that the flame is nice and blue. If it is yellow or another color, this is a sign that there is something wrong with it. Also, the flame shouldn't be wavy. Yellow and wavy flames are a sign that your furnace is dirty. Fortunately, while your furnace is turned off, you can clean the burner with a vacuum. Also, make sure to clean the area around the blower.
Make Sure the Burner is Clean
One of the most common reasons for burners to fail is that they become contaminated. For that reason, you will want to check your burner periodically to make sure that no debris would contribute to contamination.
Clean the Furnace Before Winter
One of the most important times to clean your furnace is before you start using it in the winter. During the summer, dust will often accumulate on the furnace. Usually, the furnace will need to be cleaned to make sure that it operates efficiently and to avoid damaging the furnace. Also, you must clean the furnace to remove soot and rust that results from condensation.
Inspect the Ignition System
Your furnace will not be able to generate a flame if the ignition is not functioning properly. A furnace will either use a pilot light or will rely on electronic control to allow you to avoid having a constant flame. The ignition switch might become faulty and may prevent you from keeping your home warm. A common reason for an ignition system to stop functioning properly is when it forms a clog. If the heating element looks cracked or damaged, you might need to replace it.
How you repair the heating element will depend on the instructions in your owner's manual. If you do not feel confident in your ability to repair your HVAC, make sure to contact a repair technician.
Consider Replacing the Unit
If you are not able to figure out what is wrong with the flame, you may need to purchase a new a new furnace. Furnaces are not meant to last for a long period, and a new furnace will be more efficient than older furnaces.
