4 Reasons Why Your HVAC Unit is Overheating

An HVAC unit is an essential element in your home during the hot and cold seasons. While the unit has a lifespan, it can encounter some challenges due to various reasons.

One major problem is overheating. This is a common occurrence in most units, and it can worsen and damage the system if you do not fix the problem in time. Here are four reasons why your HVAC unit could be overheating.

1. Dirty Air Filters

Air filters prevent dirt from getting into the air conditioner. When the air filter blocks, it causes the system to work harder, leading to overheating. You will not be able to enjoy enough airflow in your home when the unit overheats.

In this case, you will need to replace the air filters often to avoid damaging the unit. Your air filter will clog more often if you have pets at home or if someone smokes inside. We recommend changing the air filters at least once a month.

2. Leaking Refrigerant

When the refrigerant leaks, it can prevent the air conditioner from working at it's best. This causes it to overwork and overheat, leading to insufficient cooling in the home.

You will need a professional HVAC contractor to fix the refrigerant leaks. This is a sensitive part that requires expertise. A professional can resolve the issue without damaging the system.

3. Dirty Condenser Coils

When condenser coils accumulate dirt, they will not heat well. The coils work hard to release heat because of the dirt. The refrigerant cannot absorb more heat. This causes the air conditioner to blow out insufficient air.

As it continues running, it starts overheating. It struggles to reach your thermostat temperature settings. In this case, you can invest in annual maintenance to keep the unit clean. This helps to prevent it from developing issues.

4. Dirty Fan Blades

When the fan blades collect dirt, the HVAC struggles to work well, causing it to overheat. If you do not clean the fan blades, the HVAC can shut down, especially when the blades fill up with dust and grime.

It makes the blades heavier than normal. This places a strain on the motor, making it struggle to work well. This leads to overheating of the system and will cause it to shut down.
