The answer to 'how does preventive maintenance work' is that preventive maintenance is a proactive approach to maintaining your HVAC system. It involves regularly scheduled inspections, cleanings, and tune-ups to keep your system running efficiently and prevent costly breakdowns.
During a preventive maintenance visit, an HVAC technician will thoroughly inspect your system, clean components, replace air filters, test electrical connections, and make any necessary adjustments. This helps identify and address small issues before they turn into bigger problems. Regular preventive maintenance can extend the life of your HVAC system, improve its energy efficiency, and reduce the need for expensive repairs down the line.
