HVAC Unit is Overheating

4 Reasons Why Your HVAC Unit is Overheating

One of the most common issues with HVAC units is overheating. This can cause the circuit breaker to continue to trip. If you want to know why the unit is overheating, there are a few leading causes to consider.

1. Refrigerant Leaks


Your air conditioner may not be capable of cooling if there's a refrigerant leak. The unit tends to overwork until it overheats when there's not enough refrigerant. An HVAC professional needs to fix the issue. This is to make sure to avoid safety issues or damage.

There are a few signs refrigerant leaks are present. This includes not cooling as it used to, keeping the house cool, or if the outside of the unit has a layer of ice covering it.

2. Dirty Air Filters

Many homeowners don't replace or clean their air filters every few months. This prevents the air from flowing as it should. Dirty air filters make the HVAC system work harder than usual. This can place extra strain on the unit, leading to overheating. It's important to replace the air filter more often if you have pets in the home. If someone in the household smokes inside, you should change it more often as well.

3. Dirty Condenser Coils

If you fail to clean your HVAC unit's parts, it can cause the condenser coils to become dirty. The coils can fail to release enough heat if they're dirty. This can also happen if there isn't enough ventilation around the unit. Investing in annual HVAC maintenance keeps the parts clean and prevents common issues.

4. Issues with the Fan Blades

Your HVAC system can shut down due to overheating. It could be due to dirty fan blades. If you haven't cleaned your HVAC system, it can cause the fan blades to build-up dust and grime. The blades can become heavier than normal to move. This places more strain on the motor. If your motor starts to work too hard to run, it can lead to the system overheating and shutting down.
