The answer to 'how does preventive maintenance work' is that preventive maintenance is a proactive approach to maintaining your HVAC system to prevent major issues and breakdowns. It involves regularly scheduled maintenance and tune-ups by a professional HVAC technician to inspect, clean, and service key components of your system.
Preventive maintenance typically includes tasks like changing air filters, inspecting and cleaning the condenser coils, checking refrigerant levels, lubricating moving parts, and testing electrical connections. This helps ensure your HVAC system is running efficiently and can catch any minor issues before they turn into larger, more expensive problems down the line.
