To ensure that your heat pump has a long service life and operates efficiently, regular maintenance is required. Homeowners can do monthly maintenance themselves for both central and mini-split heat pumps. During regular maintenance you should follow the manufacturer’s instructions.

A yearly heat pump inspection is also recommended and should be done by a competent service contractor. During the yearly inspection, the service contractor should check the refrigerant levels and make any mechanical or electrical adjustments.
