The answer to 'when to service heat pump' is that heat pumps should be serviced annually, typically before the start of the heating or cooling season. Regular maintenance is crucial to ensure your heat pump operates efficiently and safely.
During a service visit, an HVAC technician will inspect the unit, clean the coils, check refrigerant levels, test electrical components, and make any necessary adjustments or repairs. This helps extend the life of your heat pump and prevents costly breakdowns down the road.
