HVAC Warranty Transfer When Selling Your Home Ontario 2026: Manufacturer Rules, Fees, and Documentation

What Actually Transfers and What Does Not

Residential HVAC warranties in Ontario are typically split into three components: the parts warranty (standard 10 years when registered), the heat exchanger warranty on a furnace (often lifetime to original owner or 20 years pro-rated), and any replacement or labour coverage the dealer or manufacturer has added on top. When a home is sold, these three pieces almost never transfer the same way.[1]

The parts warranty is the piece most likely to transfer, and it is the piece that matters most to a buyer because the compressor, the circuit board, and the blower motor are the expensive failures. The heat exchanger warranty is usually the first thing the manufacturer carves out. Carrier, Lennox, and Goodman all convert the lifetime heat exchanger warranty to a shorter pro-rated term as soon as the equipment changes ownership, and in some cases the lifetime coverage ends entirely at transfer. That is by design. The lifetime coverage exists to reward the original buyer for choosing the brand, not to follow the equipment forever.[2]

Dealer-added labour coverage almost never transfers. That contract is between the original homeowner and the installing contractor, and the contractor has no obligation to honour it for a new occupant. If the previous owner paid for a 10 year labour plan through the installer, the new owner cannot assume it. The buyer can ask the installing contractor whether they will reinstate it for a fee, but it is not a right.

Major Manufacturer Transfer Rules (2026)

The rules below are current as of April 2026 and cover the brands most commonly installed in Ontario homes. Always confirm the specific terms on the manufacturer's warranty certificate that came with the original equipment, because terms change from year to year and from model series to model series.

Carrier

Carrier allows warranty transfer but charges an administrative fee, typically around $100 per unit, and the transferred warranty is converted from the original term to a shorter transferable term. For example, a 10 year parts warranty registered to the original owner may transfer as a 5 year remainder to the new owner. The transfer request has to be submitted through Carrier's online owner portal within 90 days of closing, with the serial number, install date, and proof of ownership change.[1] Carrier's standard base parts warranty in our brand reliability data is 10 years limited.[1]

Trane

Trane is the most buyer-friendly of the major brands. Trane residential warranties transfer at no fee, provided the transfer is requested within 90 days of the property transfer date. The standard Trane warranty in our data is 10 year parts with lifetime heat exchanger coverage on the furnace side.[2] The lifetime heat exchanger coverage does not follow a new owner unchanged. It transfers as a 20 year limited term from the original installation date, which is generous compared to Carrier or Lennox but still a reduction from the original terms.

Lennox

Lennox allows limited transfer. Not all Lennox residential warranties are transferable, and for the ones that are, the parts coverage is typically reduced to 5 years from the original installation date, and the heat exchanger coverage is capped at a 20 year pro-rated term. Lennox charges a transfer fee and requires the request within 60 days of closing. The standard Lennox base warranty is 10 year parts with 20 year heat exchanger on some models.[3]

Goodman (Daikin)

Goodman, now part of Daikin, pro-rates the transferable warranty. The 10 year parts warranty registered to the original owner transfers as a pro-rated remainder based on the original installation date. A unit installed 3 years before the home sale transfers with 7 years of parts coverage remaining. The lifetime heat exchanger coverage on a Goodman furnace converts to a 20 year limited term on transfer. Goodman charges a transfer fee in the $50 to $100 range and asks for the request within 60 days of closing. Standard Goodman base warranty is 10 year parts with lifetime heat exchanger (furnace), original owner only.[4]

Napoleon

Napoleon (a Canadian manufacturer, headquartered in Barrie, ON) allows warranty transfer on residential furnaces and air conditioners. The transferable warranty is typically the parts coverage (10 years registered, 5 years unregistered) and a pro-rated 20 year heat exchanger term in place of the lifetime coverage to the original owner. Napoleon charges a small administrative fee and requires the new owner to register the transfer through Napoleon's warranty portal. Series-specific warranty terms in our pricing data show the 9500, 9600, and 9700 furnace series all carry the same 10 year parts / lifetime heat exchanger structure to the original owner, with pro-rated reductions on transfer.[5]

Rheem

Rheem's residential warranty is 10 year parts limited when registered within 60 days of installation.[6] The transferable portion is reduced on change of ownership, typically to 5 years remaining on the parts, and the labour coverage (if any) does not transfer. Rheem charges an administrative fee for the transfer and requires the request within 90 days of closing. Rheem's residential warranty registration is handled online through the Rheem owner portal.

Typical Transfer Fees

The spread across brands is real money. A couple selling a home with a 2 year old Carrier furnace and a matched Carrier AC would see the buyer pay roughly $200 in transfer fees. A similar sale with Trane equipment would cost the buyer nothing in fees. If warranty transferability matters to you as a seller, check the manufacturer's current policy before you list.

Time Window After Closing

The filing window is not a soft target. It is a contractual deadline in the manufacturer's warranty terms, and if the buyer misses it, the manufacturer can refuse the transfer. In practice, a 30 day window passes faster than people expect when the buyer is also arranging movers, utilities, insurance, and closing paperwork. Assume the transfer will slip if it is not handled in the first two weeks after closing.

A practical timeline that works:

1. Seller gathers the warranty paperwork (original install invoice, model and serial numbers, registration confirmation) before the closing date and hands the package to the buyer at key exchange or via the real estate lawyer.
2. Buyer's lawyer includes a clause in the Agreement of Purchase and Sale referencing the equipment and confirming the seller will provide the warranty documentation on or before closing. OREA's standard forms include schedules where this can be added cleanly.[7]
3. Within 7 days of closing, the buyer files the transfer request directly with the manufacturer (online portal for most brands) and pays the fee.
4. Buyer keeps the confirmation email and the original install paperwork together, in case anything is disputed later.

Documentation the Buyer Needs

The seller's job is to deliver a clean package of HVAC paperwork at closing. The buyer's job is to read it and file the transfer promptly. The package should include:

• Original installation invoice, showing the install date, the installing contractor, the list of equipment installed, and ideally the price paid (the price is not required for warranty transfer, but it helps establish the age and installer).
• Model and serial numbers of each piece of equipment. These are on the nameplate stickers on the furnace cabinet and the AC condenser. Photograph them with a phone and print the photos if the stickers are hard to read.
• Registration confirmation, if the seller registered the equipment online at installation. Manufacturers assume registration happened within 60 to 90 days of install. If it did not, the warranty may already be shortened to the unregistered term (typically 5 years instead of 10).
• Any extended warranty or labour plan paperwork, with a note on whether it is transferable to the new owner.
• The installing contractor's name and phone number. The buyer may want to use the same contractor for annual maintenance to keep service records continuous, which helps any warranty claim later on.

OREA and REBBA Disclosure Implications

The OREA Agreement of Purchase and Sale (Form 100 for freehold, Form 101 for condo) does not have a pre-printed warranty transfer clause, but the standard forms include schedules where representations and warranties about mechanical systems are routinely added.[7] If a seller represents that "the furnace is under warranty until 2032" in a listing, on a Seller Property Information Statement (SPIS), or verbally through the listing agent, that representation creates reliance the buyer can act on.

REBBA (the Real Estate and Business Brokers Act, 2002, continued under the Trust in Real Estate Services Act) obligates salespeople to disclose material facts they know or reasonably should know.[8] Age and condition of major HVAC systems qualifies as a material fact in most residential transactions, especially for equipment that is close to the end of its expected service life. The practical implication for a seller is that overstating the warranty (saying it transfers when it does not, or overstating the remaining term) can create a claim after closing.

The cleaner path for a seller is to provide the original documentation, tell the buyer the equipment is registered and the manufacturer's transfer terms apply, and let the buyer verify the specifics directly with the manufacturer. That shifts the verification burden to where it belongs, while still giving the buyer everything they need.

Working With Your Real Estate Lawyer

For most residential sales in Ontario, HVAC warranty transfer is a small enough line item that it never makes it into the lawyer's conversation. It probably should, at least as a one-line check. A competent real estate lawyer can add a standard representation to the schedule of the Agreement of Purchase and Sale that the seller will deliver the HVAC install documentation on or before closing, and that the seller confirms the equipment has been registered with the manufacturer (or disclose that it has not).

If the home is newer and the equipment is under 5 years old, the warranty transfer is worth real money to the buyer (potentially $2,000 to $5,000 in future repair coverage). For older equipment near the end of its warranty term, the transfer is more of a formality. Scale the legal effort accordingly. Do not pay a lawyer $400 to negotiate the transfer of a 9 year old furnace that has 1 year of coverage left.
