What Is Preventive Maintenance for HVAC Systems and Why Is It Important?

Preventive maintenance is a scheduled HVAC tune-up that inspects, cleans, tests, and tunes your system. It matters because it “detects small issues before they become major repairs” and helps keep indoor air quality at its peak. For AC, this includes: “Checking refrigerant levels and pressure; Inspecting and cleaning condenser coils; Lubricating moving parts; Testing thermostat accuracy; Inspecting electrical connections; Checking and clearing the condensate drain; Replacing or cleaning air filters; Running a full system performance test.” Furnace tune-ups include cleaning components and confirming proper power use.
