The coverage of an HVAC tune-up under a home warranty policy hinges on the particulars of your individual plan. Home warranties can differ significantly in their offerings, with some including HVAC coverage as part of their standard package, while others may offer it as an optional add-on. In some cases, HVAC tune-ups may be excluded from coverage altogether.

Understanding the specifics of your coverage is vital. We recommend carefully reviewing your warranty contract or reaching out to your provider directly to gain clarity on the extent of coverage for routine HVAC tune-ups.

Typically, it’s important to note that home warranties primarily prioritize addressing unexpected system failures, such as major component breakdowns. Routine maintenance, including tune-ups, is often considered the homeowner’s responsibility.
