During the winter and summer months in Australia, your HVAC unit plays a critical role in your home comfort. Sometimes, you may get home after a long day at work only to discover your HVAC unit is not working. This is not uncommon, as often, when it works too hard for too long, specific issues tend to arise. That may result in your HVAC unit overheating, and when this happens, it could be a fault in the circuit breaker. In some cases, the circuit breaker could stop working entirely

To avoid this happening to you, it's a smart option to familiarize yourself with the potential causes of overheating your HVAC. Low refrigerant, clogged air filters, dirty condenser coils, and a lack of maintenance are all some of the possible reasons for your HVAC unit overheating. Therefore, we'll go over each of these causes in further detail and offer a few tips on dealing with them.

1) Clogged and Dirty Air Filter

The HVAC filter in your home is responsible for preventing contaminants from coming into your home. Therefore, it tends to collect dust, pet hair, and dirt in the process. Sometimes, the air filter gets clogged; hence reducing the airflow through the system. This means that the system will have to work harder to keep your home cool or warm. The strain on the systems causes your HVAC unit to overheat. That is why you need to regularly replace your air filter; especially when you notice it's starting to look grimy.

2) Refrigerant Leak

The HVAC unit ideally is a closed-loop system with adequate refrigerant to cool your space. The refrigerant makes the air cool by removing all the heat from the air. If there is a leak in the refrigerant, it reduces its capacity, putting  the HVAC unit under strain. When the HVAC has to strain to cool your home, it tends to overheat. If you detect a refrigerant leak, call a technician immediately. Such an issue needs a professional to fix it.

3) Dirty Cooling Coils

Cooling coils are part of the HVAC unit that is refrigerant-filled. Like dirty air filters, when the cooling coils are dirty, they force the HVAC unit to work harder and for more extended periods to deliver good quality air. When the unit strains to reach the desired temperature, it results in overheating. While you may think of cleaning the cooling coils yourself, it's better to engage a professional.

4) Corroded Electrical Connections

Sometimes if there is an issue with the electrical connections in your HVAC, the system may overheat. The corroded wires may also lead to overheating. Electrical malfunctions in the HVAC unit can be risky, as they can cause a fire. That is why you need to hire experts to inspect if everything is working correctly.
