An HVAC maintenance plan — also called a maintenance agreement or service contract — is an annual arrangement with a licensed HVAC contractor to perform scheduled preventive maintenance on your heating and cooling system. Most plans cover two visits per year (one for AC, one for heating), typically priced between $150 and $350 annually. Plans often include labor discounts on repairs, priority scheduling during peak seasons, and a written service report after each visit. Whether a plan makes sense depends on your system's age, the contractor's reputation, and what the agreement actually covers.
What a Tune-Up Includes
A maintenance plan visit should cover the same scope as a standalone tune-up — but confirm this in the contract before signing. On the AC visit, look for coil cleaning (evaporator and condenser), refrigerant charge measurement, capacitor and contactor testing, condensate drain flush, and thermostat calibration. On the heating visit, look for heat exchanger inspection, ignitor and flame sensor testing, gas valve and burner check, and inducer motor verification. Better plans also include a filter replacement at each visit and document every inspection item in a written service record. Parts and refrigerant are almost always excluded from plan pricing — these are billed separately if needed.
How Often and Why It Pays Off
Maintenance agreements are designed around a biannual service cadence — spring for cooling, fall for heating — which aligns with ACCA recommendations and most manufacturer warranty requirements. The financial case for a plan rests on three pillars: consistent scheduling (homeowners with plans are far more likely to stay current on maintenance), priority access during summer and winter service surges when appointment wait times can stretch to days, and repair discounts that typically run 10 to 20 percent off labor. For systems over 7 to 10 years old, where component failures become more likely, those discounts can offset the plan cost in a single service call. Plans also provide a documented maintenance history that supports warranty claims and resale value disclosures.
Choosing a Licensed Contractor
Read the maintenance contract before signing. Confirm exactly which tasks are included in each visit, what the cancellation policy is, and whether the plan price is locked or subject to annual increases. Verify that the contractor is licensed and insured in your state and that technicians hold EPA Section 608 certification for refrigerant handling. A reputable contractor will give you a written service report after every visit and will present documented evidence before recommending any additional repair. Avoid contracts that auto-renew without notice or that bundle diagnostics fees you would normally expect to be included.
