For most homes, the standard is twice a year: a heating tune-up in the fall and an AC tune-up in the spring. Heat pumps that run year-round benefit from servicing twice annually as well. Regular maintenance catches small issues early, keeps efficiency high, maintains manufacturer warranties, and extends equipment life. Between visits, change filters every 1-3 months.
