If plants, shrubs, or other objects are too close to the condenser, the fan can’t move as much air as is required for maximum efficiency. The exterior doesn’t have to be cleaned; in fact, cleaning chemicals could actually damage the protective finish of the cabinet. Be careful when trimming plants near the unit, because it can be DANGEROUS. Damaging the control or cooling coil can cause electrical shock.
The best practice is to have your local HVAC dealer perform a cooling system check. They’ll evaluate your entire system to ensure you stay cool.
