Air and ground source heat pump maintenance involves the regular inspection, cleaning, and servicing of systems to ensure they operate efficiently and reliably. For air source heat pumps, this includes cleaning filters, coils, and fans, checking refrigerant levels, inspecting electrical connections, and clearing debris from outdoor units. Ground source systems require inspection of ground loop integrity and antifreeze levels, flushing heat exchangers, and testing circulation pumps and controls. Routine maintenance—typically carried out annually—helps prevent breakdowns, improve energy efficiency, prolong system lifespan, and maintain warranty compliance. By keeping heat pumps in optimal condition, property owners can reduce energy bills, ensure consistent comfort, and minimize their environmental impact.
