“But I Have a Home Warranty” Isn’t the Safety Net You Think It Is
If you’re searching for what happens when your AC breaks and you’re wondering whether your home warranty or your HVAC’s manufacturer warranty pays for it, here’s the part nobody tells you upfront: they’re not interchangeable, and the order matters.
A manufacturer’s warranty comes from the company that built your compressor, coil, or furnace — Carrier, Trane, Lennox, whoever made the equipment in your attic or side yard. It typically covers parts for 5-10 years, but only if the unit was registered within a set window after installation. Miss that window, and most manufacturers quietly drop your coverage down to a bare-minimum default (often just 5 years instead of 10) — no letter, no warning, it just happens in the background.
A home warranty is a completely different animal: a service contract you or a previous homeowner purchased, covering a range of home systems and appliances for a set annual fee.
Here’s where people get burned: home warranty companies do not take your word for it. When you file a claim, most of them require you to exhaust the manufacturer’s warranty first — and they verify that using the installation date and registration paperwork, not a phone call where you say “I think it’s still covered.” If there’s no registration on file, or if the paperwork doesn’t clearly show when the system went in and who installed it, the home warranty company can deny the claim or push the cost back onto you, telling you to go collect from the manufacturer first — even if you never registered anything and now can’t.
In other words: the burden of proof is on you, and most people don’t even know there’s a form to fill out.
The Fix Is Boring, Which Is Exactly Why Nobody Does It
Registering a new HVAC system with the manufacturer takes a few minutes, but it’s the kind of thing that falls through the cracks between “the install crew leaves” and “you’re back to your normal life.” Most homeowners don’t even know it’s their responsibility — they assume it’s automatic, or that the installing company handled it.
At Delta T, it’s built into every install. We register your system with the manufacturer as a standard part of the job — not an upsell, not a follow-up call you have to remember to make. You get the paperwork, you get the full warranty term you paid for, and if a home warranty company ever asks for proof, it exists.
Selling Your Home? Your Warranty Doesn’t Automatically Come With You (or Go With the Buyer)
Here’s the second gap almost nobody catches: many manufacturer warranties are transferable to a new homeowner — but only if someone actively files a transfer request, usually within a specific window after the sale closes. If that step gets skipped in the chaos of moving, the warranty can lapse for the new owner, or a previous owner’s coverage can end up in limbo with the manufacturer having no record of who currently owns the equipment.
If you’re a Delta T customer and you’re selling your home, just let us know. We’ll handle the manufacturer transfer paperwork so the next owner starts with a clean, active warranty — and so you’re not the name still attached to a system you no longer own.
Them vs. Us
| What Other Companies Do | What Delta T Does |
|---|---|
| Leave registration up to you — if you don’t know to do it, it’s your problem | We register every install with the manufacturer as a standard step, no reminder needed |
| Assume you’ll remember to transfer the warranty when you sell | We’ll file the transfer for you — just tell us you’re selling |
| Let a home warranty company deny your claim over missing paperwork | We keep your registration on file so proof is never the issue |
| Treat warranty admin as an afterthought | We treat it as part of doing the job right the first time |
“I’ve seen folks get denied on a claim that should’ve been covered, just because nobody filled out a form ten years ago. That’s not on the homeowner — that’s on whoever installed it and didn’t finish the job. We register every system we put in. It’s not extra, it’s just part of doing it right.”

FAQ
Do I need to register my HVAC system’s warranty myself?
If your installer didn’t do it for you, yes — and there’s usually a deadline (often 60-90 days from install, though it varies by manufacturer) before the full warranty term locks in at a reduced default.
Will my home warranty company just cover the repair if my manufacturer warranty lapsed?
Not necessarily. Many home warranty contracts require you to pursue the manufacturer’s warranty first, and they check the installation date and registration status to determine what should have been covered — regardless of what you knew or didn’t know.
Can I transfer my HVAC warranty when I sell my house?
Often, yes — most manufacturer warranties are transferable, but it requires an active transfer request, usually within a window after closing. It doesn’t happen automatically.
What if Delta T installed my system — do I need to do anything?
No extra work on your end for registration; we handled that at install. If you’re selling your home, just reach out and we’ll take care of the transfer paperwork too.
