Most furnaces last 15–20 years and most air conditioners last 12–15 years, though Missouri's hot summers and cold winters can shorten that lifespan if a system isn't regularly maintained. Annual tune-ups, timely filter changes, and prompt repairs are the biggest factors in getting the full expected life out of your system. If your system is over 10 years old and needs frequent repairs, it may be more cost-effective to replace than repair.

A standard HVAC tune-up includes inspecting and cleaning key components, checking refrigerant levels, testing electrical connections, calibrating the thermostat, and verifying the system is running at proper efficiency. For furnaces, this also includes checking the heat exchanger and burner assembly; for AC units, it includes checking coolant levels and condenser coils. Regular tune-ups catch small issues before they turn into costly breakdowns.

Schedule AC maintenance in spring (March–April) before peak summer heat, and furnace maintenance in fall (September–October) before winter cold sets in. Servicing before each season starts means shorter wait times and ensures your system is ready when you need it most. Waiting until a system fails during a heat wave or cold snap often means longer repair wait times and higher emergency service costs.

The Comfort Guard Advantage Plan includes scheduled seasonal maintenance, priority service scheduling, and discounts on repairs — which typically pays for itself by extending system life and catching problems early. For most homeowners, the plan costs less than a single unexpected emergency repair call, while also qualifying you for faster response times.
