Mr. Heater warranty for air quality

13/100 Warranty ScoreRanked 26 of 30 brands
The short version

Mr. Heater doesn't cover everything, but keeps whole product (parts and replacement) covered to 1 year. That full coverage is shorter than most of the 30 brands we compared, which typically cover 1 year in full. You don't need to register to get this coverage.

From Mr. Heater's published warranty, checked October 2026.

What it leaves out

  • Normal wear and tear
Good to know before you buy
  • Keep your receipt: you must send proof of purchase and the heater's serial number.
  • Reconditioned heaters get only 90 days of coverage.
  • Using third-party accessories with the heater voids the warranty.
  • Empty all fuel before shipping a heater back.
