When to Schedule an HVAC Tune Up

Scheduling regular tune-ups is crucial to maintaining HVAC system health. Ideally, tune-ups should be performed at least once a year, with the timing tailored to the system’s usage patterns and climate conditions.

  • Cooling Systems: Schedule tune-ups in the spring before the peak cooling season begins.
  • Heating Systems: Schedule tune-ups in the fall before the heating season starts.

Additional factors that might necessitate more frequent tune-ups include:

  • Systems that are over 10 years old.
  • Units that experience heavy usage due to extreme weather conditions.
  • Homes with pets, smokers, or residents with allergies requiring more frequent filter changes.
  • Recent repairs or system modifications that require follow-up checks.

By adhering to an appropriate maintenance schedule, homeowners and building managers can optimize comfort, efficiency, and reliability throughout the year.
