HOW OFTEN SHOULD COMMERCIAL HVAC SYSTEMS BE SERVICES?

Most commercial HVAC systems should be professionally maintained at least twice per year, typically in the spring and fall. Facilities with critical HVAC demands—such as healthcare, manufacturing, or high-occupancy buildings—may require more frequent service. Regular maintenance helps maintain manufacturer warranties, improve efficiency, and prevent small issues from turning into costly failures during peak heating or cooling seasons. Seasonal maintenance helps:

  • Reduce mid-season breakdowns

  • Improve energy efficiency during peak demand

  • Identify worn components before failure

  • Maintain occupant comfort year-round
