Regular maintenance keeps a heating and cooling system efficient, catches small problems before they become breakdowns, and is often required to keep the manufacturer warranty valid. Here's what it costs and what a real tune-up includes.
A neglected system loses efficiency every year, works harder, and fails sooner. Most manufacturers also require documented annual maintenance to honor the parts warranty. A tune-up costs far less than the repairs it prevents.
Get the cooling side serviced in spring and the heating side in fall. Many homeowners buy a maintenance plan that bundles both visits with a discount on repairs and priority scheduling.
If a 'tune-up' takes 15 minutes and skips the checklist below, it isn't one.
Refrigerant charge and pressures, coil cleaning, condensate drain, capacitor and contactor test, airflow.
Igniter and flame sensor, burner inspection, heat-exchanger check, gas pressure, safety controls.
Tighten connections, test the capacitor and contactor, check amp draw against spec.
Replace or check the filter, inspect the blower wheel, check static pressure.
Carbon-monoxide check on gas equipment, verify all safety switches, check the flue.
A written summary of readings and any parts nearing end of life — ask for it.

A single-system tune-up runs about $75–$200; a combined heating-and-cooling visit runs $120–$300. An annual maintenance plan with both visits runs $150–$400 per year and usually includes a repair discount. Compare with the HVAC Maintenance Cost Calculator.
Twice a year is ideal — the cooling side in spring and the heating side in fall. At minimum, service each system once a year, and check the filter every month.
For most homeowners, yes. A plan bundles both seasonal visits at a discount, adds a repair discount and priority scheduling, and keeps your warranty documentation current. Run the numbers for your system to be sure.
Yes. Clean coils, correct refrigerant charge, tight electrical connections, and good airflow reduce wear and let the system run at its rated efficiency. Neglected systems commonly fail years early.
