Daikin warranty for heating & cooling
The short version
Daikin covers heating & cooling in full for 12 years, with no partial coverage after that. That full coverage is longer than most of the 25 brands we compared, which typically cover nothing in full. Some of this coverage only applies if you register the product.
From Daikin's published warranty, checked October 2026.

The fine print, decoded
What it leaves out
- Power problems
- Water damage
Good to know before you buy
- Register online within 60 days of installation to get the longer coverage (not required in California, Florida or Quebec).
- Labor is not covered; your contractor brings the defective part to a Daikin distributor.
- Unit replacement coverage needs yearly maintenance; keep your service records.
