Reasons Your Furnace in Alton, IL, is Overheating

A furnace’s purpose is to heat a home by burning fuel, such as natural gas, propane or oil. A furnace in good condition heats a home more efficiently, saving the homeowner on fuel costs. You can service your furnace to prevent it from overheating. The following are the top reasons your furnace in Alton, IL, is overheating.

Clogged Air Filters

The air filters clog when they get dirty and dust blocks the flow of air to the furnace. When this happens, the heat exchanger inside the furnace gets too hot and trips the safety switch. To prevent this from happening, make sure to seek help from a professional to replace the filters regularly.

Blocked Vents

When furniture or other items block your vents, it reduces the flow of air in the room, which makes it difficult for the furnace to cool itself effectively. Have your vents checked and make sure they’re not blocked by anything. Debris can cause unbalanced air flow and cause your furnace to overheat.

Faulty Limit Switches

A limit switch is a safety device found in furnaces that helps to prevent the system from overheating. The limit switch is a fail-safe mechanism that turns the furnace off when the temperature inside gets too high.

Incorrectly Sized Furnace

If your furnace isn’t the correct size for your home, it can cause the unit to overheat. A furnace that’s too small won’t be able to keep up with the heating demands of your home and will end up working harder than necessary. This can cause the furnace to get too hot and shut down. Make sure to seek help from a professional to determine the proper size for your home and install the right-sized furnace for optimal performance.

Dirty Burners

If the burners in your furnace are dirty, they won’t be able to generate enough heat to keep up with the heating demands of your home. This will cause the furnace to overheat and shut off. Have a professional clean and inspect the burners regularly to prevent this from happening.

Taking preventive measures will ensure your furnace is running efficiently and safely. If you have problems with your furnace overheating, contact Den-Son Inc. Cooling & Heating to schedule a maintenance or repair services.
