Why is My Furnace in Calhoun, GA, Overheating?

Have you noticed short cycling or a wheezing sound coming from your home’s supply vents? These could be signs that your furnace is overheating. Here are three reasons your furnace in Calhoun, GA, is overheating:

Restricted Airflow

The United States Environmental Protection Agency approximates that people spend 90% of their time indoors. As such, you need to make your home habitable by ensuring that your furnace is operating well.

One of the things that may make your furnace overheat is inadequate airflow. Dirt can clog the air filter and thus prevent enough air from reaching the heating system. Your furnace starts to overheat when the amount of air reaching the heating system isn’t enough.

Blocked return vents can also block air from circulating in your system, thus causing your furnace to overheat. Furniture, couches, trash cans and chairs can block the return vents. You should place such items at least 10 inches away.

A dirty blower wheel can also make your furnace overheat because it works by blowing air over the heat exchanger. However, it cannot work well if it is dirty, thus reducing the amount of air blown over the heat exchanger. This can cause your furnace to overheat.

Old Age

Your furnace has a lifespan of 15-20 years. Its functionality will naturally diminish because of wear and tear. Your furnace has built-in functionality that helps it sensor imminent overheating and turns off the system to avoid any damage. A sizeable number of old furnaces aren’t able to recognize the overheating.

If your furnace has operated for more than a decade, it’s time to start considering replacing it. A new furnace can perform well and will be unlikely to experience an overheating problem. Nonetheless, it’s always advisable to ask an HVAC expert to inspect the issue thoroughly.

Mechanical Problem

It’s crucial to regularly maintain your furnace to keep it in good condition and prevent premature failure. There could be a problem with the wiring, motor or fan blower. If you suspect a mechanical failure, contact your HVAC expert to diagnose and fix it.
