HVAC Maintenance Costs & Schedule

Regular filter changes and seasonal tune-ups keep systems efficient and reduce mid-season no-cool or no-heat surprises.

Direct answer

Plan on filter changes every 1-3 months and a professional tune-up once or twice a year. Modeled annual maintenance for a typical split system often lands a few hundred dollars, excluding major repairs.
