3 Common Furnace Problems and Causes


Unraveling the mystery behind common heating and air conditioning problems.

Your heating and air conditioning system might seem like a big mystery, especially if you have an issue with your furnace. The good news is there are some common furnace problems you should be able to identify. Here are three of them, and the probable causes:

#1: Your Furnace Is Overworking

If it seems like your furnace turns on more frequently than usual or if you notice an uptick in your monthly utility bills, it’s definitely a problem. The most common cause for an overworking furnace is a dirty air filter. The filter is in place to catch pollutants before they enter your heating system. The filter not only protects your air, but it also protects the HVAC equipment. If the filter is dirty or clogged, the furnace has to work harder to pull air through it to do its job.

#2: Strange Squealing Sounds

A common issue with HVAC equipment is a squealing sound when it’s running. This is often caused by a blower belt that has slipped, frayed, or worn out. The belt should run smoothly and quietly to run the blower. Lack of maintenance is the most common reason for a noisy belt.

#3: Frequent Cycling

If your furnace turns on and off over and over again in a short amount of time, that’s called short cycling. A dirty air filter or a faulty or malfunctioning thermostat is often the cause.

No matter what’s going on with your furnace, you don’t have to ignore the problems and just live with them. Maintaining a properly running system is the priority for a good HVAC company. Contact the best team in the area at H.H. Hovey for all of your heating and air conditioning needs.
