Warranty: labor vs. parts on a heat pump quote: what it should say
Quick answer
A heat pump usually has two warranties: the manufacturer’s parts warranty (which can depend on registering the equipment) and the installer’s own labor warranty, which is often much shorter. A quote should state both lengths, who registers the equipment, and what is excluded.
What a complete quote states
- Manufacturer parts warranty length, and whether it depends on registration and by when.
- Installer labor warranty length, in writing, and what it covers.
- Who registers the equipment with the manufacturer.
- Exclusions and conditions, such as required maintenance, and whether any extended warranty is included or extra.
Red flags when it is missing or vague
- “10-year warranty” with no mention of parts versus labor.
- No labor warranty stated.
- Registration left to you without telling you the deadline.
- An extended warranty bundled into the price without a separate line.
Three questions to send the installer
- How long is the manufacturer’s parts warranty, and does it require registration? Will you register it, and by when?
- How long is your labor warranty, and what does it cover and exclude?
- Is any extended warranty or service plan included in the total? What does it add, and what does it cost?
Why two quotes differ here
Two quotes for the same equipment can carry very different labor coverage: one year from one installer, ten from another. That difference is worth money if something fails, and it is often the only part of the warranty the installer controls.
Ask each installer to put both warranties in writing, and keep the registration confirmation with your records.
What the sources say
The FTC says a warranty “must be available for you to read before you buy”, that “sometimes you’ll have to return a product registration card first to qualify for warranty service”, and that an extended warranty or service contract “costs extra and is sold separately.” Under federal warranty law a “full” warranty can’t require registration; a “limited” one can, and may cover parts but not labor.
Manufacturers’ registration windows differ. Trane says its Registered Limited Warranty requires registration “within 60 days of installation” and that with its limited warranties “you’re only responsible for the cost of labor and shipping.” Lennox says extended parts coverage requires registration “within 60 days of installation.” Bryant (a Carrier brand) offers 10-year parts coverage “if registered within 90 days of installation.”
Programs sometimes set minimums: the NYS Clean Heat manual requires “a minimum five (5) year manufacturer’s warranty for parts including the compressor.” Mass Save’s rebate form tells customers to contact the installer about warranties, since the program doesn’t provide one.
Cost
Extended warranties are priced by the installer or manufacturer. Ask for them as a separate line so you can compare.
