The answer to 'what is preventive maintenance' is preventive maintenance is the regular and systematic inspection, cleaning, adjustment, and repair of equipment and systems to prevent breakdowns and ensure reliable operation. This involves proactively maintaining HVAC systems to extend their lifespan, improve efficiency, and reduce the need for costly repairs.
Preventive maintenance typically includes tasks like changing air filters, inspecting and cleaning components, lubricating moving parts, and checking refrigerant levels. It helps identify and address minor issues before they become major problems, saving homeowners money in the long run.
