Installers of these units need to know how to handle overheating systems and take steps to ensure any damage is minimised. Below is a list of common reasons HVAC units overheat and how you can help stop them from occurring.
Clogged-up Air Filters
To prevent the airflow from becoming restricted, installers should check the air filter is clean before use. They should also advise their customers to switch out the filter every month or so, to allow the unit to breathe.
Dirty Condenser Coils
Condenser coils should be sprayed with specialised cleaning spray in order to prevent dirt from settling on them. This should be done not only during installation, but also in performance checkups, if this is a service you provide.
These leaks often happen in either accumulators or heat pump coils, when contractors fail to connect them in the correct manner. Wear and tear is also an issue and any rusting in these parts should be dealt with immediately.
Poorly Ventilated Compressors
When compressors lack a quality air supply they are unable to dissipate enough heat to cool down. Stifling the compressor is a surefire way to cause it to overheat and shutdown. Contractors should bear this in mind when installing or servicing the compressor, ensuring there are no blockages within 18 inches of the unit and at least 3 feet of airspace above it.
