At the start of spring, the weather is often still cold, and that means you’ll need to keep your furnace running to keep everyone warm. But maybe you’ve noticed your furnace isn’t doing its job as well as it was at the start of winter. What’s happening? We’ll examine some of the possible causes below.
You’ve left the same air filter in place for too long
Dirty air filters are perhaps the most common reason that furnaces fail to provide enough heat to a home. (They’re behind plenty of other problems as well.) Over time, this air filter will become clogged with dust, dirt, and other debris. This restricts the airflow and causes the furnace to work harder to circulate warm air throughout a house. Fortunately, all you have to do to fix this problem is to change the air filter. This is definitely something you should do if you’ve had the same air filter in place since the start of winter!
