HVAC warranty guides

Updated September 18, 2026

Most furnaces, air conditioners and heat pumps sold in the US carry a ten-year parts warranty that shrinks to five if nobody registers the unit in time. These guides cover how that works, brand by brand and state by state, for the people who own the equipment and for the shops that install it.

For homeowners

• HVAC warranty registration deadlines, brand by brand

  The 60- and 90-day windows for Goodman, Trane, Carrier, Lennox, Rheem, YORK, Daikin and more, and what each drops to if missed.

• How to check whether your HVAC unit is registered

  Find the serial, run the manufacturer's lookup, and read what comes back, in about five minutes.

• What voids an HVAC warranty? 7 ways coverage dies early

  Registration, maintenance records, non-OEM parts, install errors, and what does not void coverage.

• HVAC parts vs. labor warranty: who pays for what

  Manufacturer warranties cover parts, not the technician. How the bill actually splits in year one, year three and year seven.

• Does an HVAC warranty transfer when a house sells?

  Base coverage usually follows the unit; registered coverage often needs a filing and a fee. Florida and Georgia are the exceptions.

• HVAC warranty claim denied? What to check, in order

  Get the reason in writing, pull the paperwork, check your state's law, then escalate through the installer, not the 800 number.

• Georgia SB 112: the new HVAC warranty law, explained

  Since January 1, 2026, Georgia coverage can't depend on registration and follows the home on sale. It isn't retroactive.

For HVAC contractors

• How HVAC contractors should register warranties for customers

  What to capture at the install, who owns the task, when to file, and the split-system mistake that loses half the coverage.

• Selling HVAC maintenance agreements at month 11

  Why the month before first-year labor coverage ends is the easiest maintenance-plan sale you'll make, with a copy-ready email.
