4 Reasons Why Your HVAC Unit is Overheating

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 sufficient airflow in your home when the unit overheats.

In this case, you will need to replace the air filters regularly to avoid damaging the unit. Your air filter will quickly clog 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 effectively. This causes it to overwork and eventually overheat, leading to insufficient cooling in the home.

You will need to work with a professional HVAC contractor to help you repair the leaks on your refrigerant. This is a sensitive part that requires expertise because a professional can resolve the issue appropriately 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, and this causes the air conditioner to blow out insufficient air.

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

4. Dirty Fan Blades

When the fan blades accumulate dirt, the HVAC struggles to function well, causing it to overheat. If you do not take quick measures to 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 function well, which leads to overheating of the system and eventually shut down.
