What Would Cause a Furnace to Overheat?

A furnace should ensure that the room temperature is favorable, and you should ensure that the HVAC’s temperature is suitable. While producing warmth, a furnace unit should not get too hot to work.

When a furnace overheats, it not only reduces the comfort but this issue also shortens the lifespan of the heating unit. If you ignore the overheating issues, it will damage furnace components, and you will soon need a furnace replacement in Atlanta, GA. You can fix this issue if you know the source of the problem.

Reasons Behind an Overheated Furnace

Some alarming signs that let you know about your overheated furnace unit are a burning odor, repetitive short cycling, and a humming or banging noise. The sudden increase in utility bills is also an outcome of the overheated furnace unit.

If you are experiencing these issues, it’s time to know what is causing your furnace unit to overheat. Whether the problem is with residential heating or commercial HVAC in Suwanee, GA, the reasons for the problem are the same.

• No Smooth Airflow

Unrestricted airflow is a sign of a smooth furnace mechanism. If the furnace air filter is extremely dirty, it will restrict the airflow. Due to this restriction, the central heater will have to work harder to heat the room.

The outcome of this hard work is overheating of the furnace. Therefore, it is essential to replace the air filter. If you have pets at home, you should get the air filter replaced every month. Otherwise, the furnace filter needs replacement once every 3-6 months.

• Inaccurate Size

An undersized furnace takes too long to heat the room. It runs constantly without maintaining a proper heating cycle. The constantly running compressor causes a furnace to overheat.

On the other hand, an oversized furnace heats the room too quickly, and this quick operation leads to frequent short cycling. The repetitive short cycling causes mechanical failure and overheating. You should schedule a furnace replacement in Atlanta, GA, to fix this.

• Dirty Central Heater

If your furnace filter is dirty, it will let other components get dirty. The excessive grime on air vents, motor, blower, flame sensor, and exhaust pipe causes multiple malfunctions. The dirt blocks furnace ventilation.

The blocked hot air will overheat the furnace system. The absence of cleaning and preventive maintenance service can cause overheating and sooner-than-expected furnace installation in Duluth, GA.

• Electrical Problems

If the electrical wiring is in poor condition, it may short circuit. The electrical connection issues also cause low and high voltage power supply. This fluctuation in electrical flow overheats the furnace by obstructing its mechanism.

The electrical failure can damage your systems severely, leading to a furnace replacement in Suwanee. You should ensure that the electrical connections, circuit breaker, fuse box, and insulation are intact.
