HVAC Warranties and Guarantees: What to Ask Before You Sign

“Ten-year warranty” sounds reassuring, and it is easy to nod and move on. The details decide whether the warranty is worth anything. Most homeowners discover what theirs does and does not cover only when something breaks, which is the worst time to read the fine print. Read it first, and ask these questions.

Parts and labor are different promises

The manufacturer's warranty typically covers parts, such as a compressor or a coil, for a set number of years. It generally does not cover the labor to replace them, the refrigerant to refill the system or the cost of diagnosis. Labor coverage comes from the installing company, if at all, and it usually runs for a shorter period. Ask for both terms in years, in writing.

Registration can decide the length

Many manufacturers offer a longer term, often ten years instead of five, if the equipment is registered within a short period after installation. If nobody registers it, you may be left with the shorter term. Ask who will register the equipment, and ask for a copy of the confirmation.

What warranties usually exclude

• Damage from lightning, flooding, storms and power surges.
• Problems caused by poor maintenance, such as a coil clogged with debris.
• Repairs made by someone not licensed to do the work.
• Refrigerant lost to a leak after the covered period.
• Equipment installed in a way the manufacturer's instructions do not allow.

Read the exclusion list, which is often a short page, and ask what a typical covered repair looks like and what you would pay.

Maintenance can be a condition

Some warranties require proof of regular maintenance. If you skip the annual tune-up and the compressor fails from a dirty coil, the manufacturer may decline the claim. Keep records of each visit, the date, the technician and what was done. A maintenance plan that includes those records takes care of this.

Labor warranties vary widely

One year of labor is common, and some companies offer more. The longer the labor coverage, the more the company is staking its work. Ask what the labor warranty includes, whether it covers only parts that fail or any problem caused by the installation, and who you call.

Extended warranties and service contracts

Third-party extended warranties and home warranty plans cover specified repairs for a fee. Some are good value and some leave you in a long argument over what counts as covered. If you are offered one, ask who actually pays for the repair, what deductible or service fee applies, whether you can choose the technician, and how claims are decided.

Satisfaction guarantees

A company's own guarantee, such as promising to return and fix a problem with its work, matters as much as the manufacturer's. Ask exactly what it promises and for how long, and ask for it in writing as part of the proposal.

Questions to settle before you sign

1. How many years of parts coverage, and how many of labor?
2. Who registers the equipment, and what term does registration give?
3. What is excluded, and is maintenance a condition?
4. Who do I call, and how quickly will someone respond?
5. What would a typical covered repair cost me in service fees or refrigerant?

Keep the paper

File the invoice, the equipment model and serial numbers, the registration confirmation and every maintenance record in one place. If something goes wrong in year eight, that folder is what turns a conversation into a claim. We are happy to walk through a warranty with you line by line before you decide.
