HVAC Warranty FAQs

Most warranties cover defects in materials or workmanship for key components such as the compressor, coils, and heat exchanger. Labor and routine maintenance are usually not included.

Standard manufacturer warranties last between 5 to 10 years, depending on the brand and equipment type. Some manufacturers offer extended or “lifetime” coverage on major components.

The manufacturer’s warranty covers the cost of replacement parts due to defects, while the labor warranty (offered by your installer) covers the cost of the technician’s time to make repairs.

Yes, most manufacturers require registration (usually within 60–90 days of installation) to receive full coverage. Unregistered heating and air conditioning systems often default to shorter, limited warranties.

Common reasons include improper installation, lack of routine maintenance, using unlicensed contractors, or failing to replace filters and parts as recommended.

Most warranties require proof of annual professional maintenance on your heating and cooling equipment to stay valid, as neglect can lead to denied claims.

Usually not. Manufacturer warranties typically cover parts only — labor coverage depends on your installation company or an extended service plan.

Some warranties are transferable (often for a small fee) if you sell your home, while others are non-transferable. Check your manufacturer’s terms for details.

A parts warranty covers defective components, while an extended warranty can include additional years of parts and labor coverage beyond the standard term.

Start by contacting your installing contractor. They’ll diagnose the issue and handle the claim with the manufacturer on your behalf.
