HVAC warranties, registration, and claims: the operator's playbook

Warranties are where a lot of shops quietly lose money and goodwill, not on the install, but two, five, or eight years later when a part fails and everyone finds out what’s actually covered. The customer thinks “10-year warranty” means free repairs. It doesn’t. The manufacturer covers the part, sometimes, if it was registered, and never pays your real labor rate. This is the playbook for handling registration, claims, and labor coverage so warranties stop being a callback tax and start being a revenue line.

The single most expensive mistake: not registering the install

Most residential equipment ships with a base parts warranty of 5 years, which extends to 10 years only if the product is registered, usually within 60 or 90 days of installation, depending on the brand. Miss that window and the customer silently drops from 10-year to 5-year parts coverage. The gap is worth roughly $1,000-$4,000 in a future compressor or coil claim, and industry estimates put the share of installs that never get registered at 20-30%.

Here’s the part owners underrate: when a system fails in year 6 and there’s no registration on file, the homeowner doesn’t blame themselves. They blame you. You installed it, you said “10-year warranty,” and now the manufacturer says 5. That’s a reputation and chargeback risk you created by skipping a 3-minute form.

Rule: register every install yourself, the day of or the week of, and keep the confirmation. Don’t rely on the homeowner to do it, and don’t assume “the distributor handles it.” Verify. Common windows and terms (confirm current terms with your distributor; they vary by product line and change):

Brand	Register within	Registered parts	Unregistered
Lennox, Trane, American Standard, Goodman, Amana, Daikin	60 days	10 yrs (Daikin up to 12; some lines add lifetime compressor)	5 yrs
Carrier, Bryant, Rheem, York	90 days	10 yrs	5 yrs

One exception worth knowing: a few jurisdictions prohibit conditioning warranty coverage on registration (California and Florida among US states, and Québec in Canada), so equipment there may carry the full term regardless. Don’t rely on that to skip registering; register everywhere, but know the rule so you don’t misrepresent coverage to a customer in those markets.

Make it mechanical: have the tech photograph the serial/rating plate and the start-up sheet before leaving the job and email them to the office the same day. Registration gets forgotten when it depends on someone remembering a serial number after the truck has moved on. Build it into the install-close checklist alongside the AHRI certificate and the customer sign-off, and forward the registration confirmation to the customer and save the PDF in the job file. When a year-6 claim hits, the customer will swear they never registered anything; the PDF ends the argument.

Parts warranty ≠ labor warranty, and the customer conflates them

Two completely separate things cover a repair, and confusing them is where the hard conversations come from:

• Manufacturer parts warranty: replaces the defective component (compressor, coil, control board). It does not pay for the trip, the diagnosis, the refrigerant, or your tech’s hours.
• Labor warranty: comes from you, the installing contractor, or a third-party program. This is what covers the diagnostic fee and the labor to actually swap the part.

A failed compressor is the classic case: the part is “free” under the 10-year parts warranty, but the labor to reclaim refrigerant, swap the compressor, evacuate, recharge, and start up can run well past the price of the part itself. If the customer has no labor coverage, that bill is on them, and they’ll be shocked, because “it’s under warranty.”

Set this expectation at the point of sale, in writing. The proposal should state plainly: parts are covered by the manufacturer for X years if registered; labor is covered by us for Y. Ambiguity here is what turns a routine repair into a one-star review.

Why you never break even on manufacturer “labor allowance” work

Even when a manufacturer does offer some labor allowance (e.g. the first year, or a concession on an early compressor failure), understand how it pays: the manufacturer reimburses at their labor rate on their “should-take” flat time, frequently below your shop rate and for fewer hours than the job actually takes. You eat the difference.

The compressor swap is the trap to model. A manufacturer’s flat time for it might be 4-6 hours, reimbursed at maybe $85-$125/hr. The real job (recover refrigerant, pull the old compressor, braze in the new one, pressure-test with nitrogen, evacuate, recharge, start up, and often a return callback) runs closer to 8-12 hours at your rate of $150+. Do that math once and you see why “warranty work” can be quietly margin-negative. Track your actual vs. reimbursed hours on warranty jobs for six months and price accordingly, either in your flat rate or in the labor coverage you sell (below).

Practical pricing discipline for warranty parts work:

• Charge your full labor flat-rate, exactly as you would for any repair. The part being warrantied doesn’t make your tech’s time free.
• Zero or minimal markup on the warranty part itself (you’re getting it replaced at little/no cost; don’t double-dip and don’t invite a dispute).
• Track warranty jobs as their own category so you can see whether “free part” work is actually margin-negative once windshield time and admin are counted. Many shops are surprised.

Turn labor coverage into revenue, not a liability

The shops that win here stop treating labor coverage as a cost and start selling it. Two mechanisms:

1. Your own labor-warranty add-on. Bake, say, a 2-year (or up-to-10-year) labor warranty into the install proposal as a priced line item with margin built in. You control the terms and you’re pricing the risk you already carry informally.
2. Third-party extended labor / service programs (JB Warranties, Trinity, Prime, and similar, all with insurance backing and multi-state/Canada compliance). Two models to understand before you sign:
   • Commission model: you sell the plan, mark it up, earn a commission; the administrator keeps the underwriting profit. Simple, low-risk, lower ceiling.
   • Reinsurance / captive model: you own a captive warranty company funded by the premiums and keep the unused reserves as profit, controlling the claims experience. More upside, but be honest about the risk: a captive only works with enough volume and real claims data to price against. A couple of bad compressor years can wipe the reserve, and most small shops either lose money on captives or end up outsourcing the administration anyway. Don’t captive-ize until you have the install volume to support it.

Before you sign any third-party program, demand the administrator’s claims-paid history and average reimbursement time in writing. Some pay $85-$125/hr even when your rate is $150+, and a slow-paying administrator turns “covered” repairs into your float.

Either way the sales motion is the same: attach labor coverage to every install proposal. Attachment rate is where the money is made or lost. Techs and salespeople avoid the extra conversation, so script it and bundle it. Top shops hit roughly 60-70% attachment when labor coverage is bundled with a discounted maintenance agreement, versus closer to 25-35% for a standalone labor warranty. It lifts average ticket, protects your reputation (no surprise labor bills in year 4), and pairs naturally with the maintenance plan: a serviced system fails less and keeps the coverage valid. One friction point to have an answer for: the customer who already holds a home warranty. Explain what those typically don’t cover (your labor, code upgrades, matched replacement) so the value of real coverage is clear.

Filing a parts claim that actually gets paid

The mechanics, so reimbursement doesn’t stall:

1. Diagnose and document. Model + serial, the failed part’s number, failure date, symptoms, and photos. Serial number tells the manufacturer the in-warranty date. Have it right.
2. Claim through your distributor (the usual channel for residential brands). You’ll typically submit a claim form + the work order/invoice with the customer’s signature + receipts, and often return the defective part for inspection (label and keep it; tossing it can void the claim).
3. Mind the filing deadline: many programs want the claim within 30-60 days of the failure/repair date. Don’t let paperwork sit.
4. Reimbursement (for whatever portion is covered) commonly lands in under ~30 days once the claim and documentation clear.

Assign this to one person in the office and give them a checklist. Sloppy or late claim paperwork is money you earned and then left on the counter.

The unglamorous reality: the initial claim is rarely the time sink. The follow-up is. Parts get “lost in inspection,” distributor portals ask for the distributor’s original purchase invoice on top of the customer invoice, and you’ll get repeat requests for the same serial number or maintenance proof. Two habits kill most of it: build a digital folder per job at install (distributor invoice, customer invoice, AHRI cert, start-up sheet, registration PDF), and label the defective part with the job number, customer name, and failure date (and photograph it in the box with the tracking number) before it leaves the truck. Also know your distributors: some are slow payers, and that lag is your money floating, not theirs.

Why claims get denied: the avoidable ones

• No registration on file → dropped to base term (or disputes over the in-warranty date).
• No proof of maintenance. Many warranties are contingent on documented annual service. Keep a maintenance log per system. It’s also your upsell hook for a maintenance plan.
• Mismatched / unmatched system. Installing a coil and condenser that aren’t a rated (AHRI-matched) pair can void coverage. Keep the AHRI certificate with the job.
• Improper install (wrong line-set sizing, no start-up documentation, incorrect charge). The manufacturer can deny on installation error, another reason your commissioning paperwork matters.
• Non-OEM parts used in a prior repair.

Every one of these is a documentation habit, not luck.

🇨🇦 Canada notes

The major manufacturers sell and warranty through Canadian distribution the same way: register within the same window, same 5-vs-10-year parts structure. Two differences worth flagging to customers:

• Provincial consumer-protection law implies certain warranties (merchantability/fitness) that generally can’t be fully waived, and sets rules on how warranties are represented. Don’t let sales copy over-promise “free repairs.” Québec is the strictest: it prohibits conditioning coverage on registration, has a statutory “legal warranty of good working order,” and requires French-language contracts. Québec has also been strengthening durability/warranty rules for appliances including AC/heat pumps, so confirm the current Québec requirements before you sell there and adjust your sales language rather than leaning on the manufacturer’s terms alone.
• Parts availability / lead times can run longer for some brands north of the border; set the customer’s expectation on a warranty part that has to ship, and stock or source-locally for your common failures.

Extended-warranty programs like the ones above generally carry Canadian compliance. Confirm the province coverage before you attach a plan.

Checklist

• Register every install within the brand’s window (60 or 90 days), yourself, on the customer’s behalf, and save the confirmation.
• Put registration on the install-close checklist alongside the AHRI certificate and start-up sheet.
• State parts vs labor coverage plainly, in writing, on every proposal.
• Attach a labor-warranty line item (your own or a third-party program) to every install proposal.
• Charge full flat-rate labor on warranty-part repairs; don’t mark up the warrantied part.
• Keep the defective part and full documentation (model/serial, invoice, signature, photos) for every parts claim.
• File claims within 30-60 days; assign one owner for warranty paperwork.
• Keep a maintenance log per system: protects the warranty and feeds the maintenance-plan sale.
• Canada: don’t over-promise; account for parts lead times; confirm provincial coverage on extended plans.

The bottom line

The manufacturer warranty covers a part, only if you registered it, and never your real labor. Everything expensive and everything reputational lives in the gap between what “10-year warranty” sounds like and what it actually pays. Win that gap with three habits: register every single install on time, sell labor coverage as a priced, margin-bearing line on every proposal, and run clean claim paperwork. Do that and warranties stop being the thing that bites you in year 6 and become part of how the shop makes money.
