Does an HVAC warranty transfer when a house sells?
Published September 18, 2026 · Applies to residential equipment in the United States
Short answer: usually yes, but rarely automatically. The basic manufacturer warranty tends to stay with the unit on its own. The longer registered warranty often has to be transferred by the new owner, commonly within 60–90 days of closing and sometimes for a fee. In Florida (since July 2023) and Georgia (for warranties issued from 2026), the warranty moves to the buyer automatically and no fee is allowed.
A house sale is the moment an HVAC warranty is most likely to disappear without anyone noticing. The seller has stopped caring about it, the buyer doesn't know it exists, and the paperwork proving it is in a drawer that goes to the dump with the rest of the move-out clutter. Here is what actually carries over and what has to be filed.
Two warranties, two different rules
Most residential equipment carries a base limited warranty that applies to the unit regardless of registration, and a longer registered limited warranty that exists only because someone registered the unit within 60 or 90 days of installation (see the deadlines by brand). Transfer rules usually treat them differently.
- Base coverage generally stays with the equipment for the rest of its term. The new owner doesn't need to file anything to keep it.
- Registered coverage is the part that can lapse on a sale. Many brands require the buyer to file a transfer, within a set window after the sale and sometimes with a fee. Some premium tiers, such as lifetime compressor or heat-exchanger terms, are limited to the original owner entirely.
One example: Trane and American Standard
Trane publishes its rule plainly, so it is a useful reference point. Its Base Limited Warranty stays with the product automatically. To carry the Registered Limited Warranty to a new owner, the transfer must be made within 90 days of the home sale, with a one-time $99 fee. Other brands use different windows and fees, and a few don't allow registered coverage to transfer at all. The certificate for the specific model and serial number is the only thing that settles it.
States where the warranty follows the house
| Jurisdiction | What happens on sale | Applies to |
|---|---|---|
| Florida | Manufacturer's warranty transfers automatically to the new owner. No transfer fee. The term is not extended. | Residential systems, law effective July 1, 2023 |
| Georgia | Warranty transfers automatically. No fee, no filing window (SB 112). | Warranties issued or sold on or after January 1, 2026 |
| Everywhere else | The manufacturer's own transfer terms apply, including any window and fee. | Check the certificate |
California and Quebec stop manufacturers from making coverage depend on registration, but that is a separate question from transfer. A buyer there should still read the certificate's transfer section.
Buying a house: the 15-minute checklist
- Ask the seller for the installation invoice, which shows the install date and the contractor.
- Photograph the data plate on the outdoor unit and on the furnace or air handler to record the model and serial numbers.
- Ask for the registration confirmation number. If nobody has one, check whether the unit was ever registered. A transfer can't restore coverage that lapsed years ago.
- Look up the brand's transfer rule, then file the transfer inside the window and pay the fee if there is one. Put a calendar reminder at 30 days after closing, not 89.
- Save the transfer confirmation with the closing documents.
Selling a house: hand over the paper
A transferable ten-year warranty is a real selling point on a system that's three or four years old, but only if the buyer can prove it. Put the install invoice, registration confirmation and service records in the listing packet. It costs you nothing and removes one question from the inspection.
For contractors: every sale is a new customer who doesn't know you
When a home you installed changes hands, the new owner has your equipment and none of your history. A short letter that says "we installed this system, here is its warranty status and here is how to transfer it" is the most natural service introduction you will ever get to send. Shops that keep install dates, serials and confirmation numbers for every job can send it. The ones that don't have that information can't.
Keeping that record is what TenKeeper does. Every install's registration and confirmation number is stored on the unit, for $89 a month per shop.
Quick answers
Does an HVAC warranty transfer to a new homeowner?
Usually, but not always automatically. The base manufacturer warranty generally stays with the unit. The longer registered warranty often requires the new owner to file a transfer within a set window after the sale, commonly 60 to 90 days, and some brands charge a fee. Some premium coverage is limited to the original owner.
How long do I have to transfer an HVAC warranty after buying a house?
It depends on the brand. Trane, for example, requires the Registered Limited Warranty to be transferred within 90 days of the home sale. Check the warranty certificate for the specific model and serial number, and file early rather than near the deadline.
Is there a fee to transfer an HVAC warranty?
Some manufacturers charge one. Trane charges a one-time $99 fee to transfer its Registered Limited Warranty. Florida (since July 1, 2023) and Georgia (for warranties issued from January 1, 2026) prohibit transfer fees and move the warranty to the new owner automatically.
What if the previous owner never registered the HVAC system?
A transfer can only pass on coverage that exists. If the unit was never registered within its original 60- or 90-day window, in most states it is on the shorter base warranty, and filing a transfer will not restore the registered term. California, Florida, Georgia and Quebec are exceptions where registration does not decide coverage.
