4 Reasons Why Your HVAC Unit is Overheating
One of the most common issues to develop with HVAC units is overheating and 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 properly if there's a refrigerant leak present. The unit tends to overwork until it overheats when there's a lack of refrigerant present. An HVAC professional needs to address the issue to ensure the refrigerant is appropriately handled to avoid safety issues or damage.
There are a few signs refrigerant leaks are present, including if the home doesn't get as cool as it used to, the unit may have difficulty keeping the house cool, or the outside of the unit is covered in ice.
2. Dirty Air Filters
Many homeowners fail to replace or clean their air filters every few months, preventing the air from flowing as efficiently. Dirty air filters make the HVAC system work harder than usual to operate and can place excess strain on the unit, leading to overheating. It's important to replace the air filter more frequently if you have pets in the home or if someone in the household smokes inside the building.
3. Dirty Condenser Coils
If you fail to clean your HVAC unit's components, it can cause the condenser coils to become dirty and grimy. The coils can fail to release enough heat if they're dirty and there isn't enough ventilation around the unit. Investing in annual HVAC maintenance is necessary to keep the parts clean and prevent developing issues.
4. Issues with the Fan Blades
Your HVAC system can shut down due to overheating due to dirty fan blades. If you haven't scheduled a proper cleaning of your HVAC system in the last year, it can cause the fan blades to develop a build-up of dust and grime. The blades can become heavier than normal to move, which 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.
