How Often Should You Service Your HVAC?

As a rule, service your HVAC twice a year: a cooling tune-up in spring and a heating check in fall. In humid, hard-running Gulf Coast conditions, that cadence keeps coils clean, drains clear, and the refrigerant charge correct — and it helps satisfy equipment warranties that often require documented maintenance.

Written from Air It Up's first-hand field experience across Greater New Orleans since 2000 and reviewed for accuracy by owner Mike Mavromatis. Equipment specifics (warranty terms, efficiency ratings) reflect manufacturer-published information at the time of writing — always confirm current terms for your exact model.

The twice-a-year rule

Two visits a year — cooling before summer, heating before winter — match our two demand seasons. Each visit verifies the charge, clears the condensate drain, and cleans the system before peak use.

When you need more frequent service

  • Coastal or marine exposure, where salt accelerates corrosion of the outdoor coil.
  • Rental properties and older systems that need closer monitoring.

Failure modes of neglect

Skipping service lets efficiency slide, invites a surprise failure on the hottest or coldest day, and can void warranty coverage that requires proof of maintenance.

Proof and your next step

Twice-yearly service is the single best habit for reliability in our climate. Set up a maintenance visit.

Frequently Asked Questions

Is twice a year really necessary here?
For most systems in our humid, long-cooling-season climate, yes. Spring and fall visits keep the system efficient and reliable and protect warranty coverage.
Does maintenance affect my warranty?
It can. Many manufacturers require documented regular maintenance to honor parts claims, so keeping a service record protects your coverage.
