Honeywell Home warranty for thermostats
The short version
Honeywell Home doesn't cover everything, but keeps whole thermostat (excl. battery) covered to 2 years. That full coverage is the same as most of the 5 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.
From Honeywell Home's published warranty, checked October 2026.
