MrCool Warranty Programs

Each unit comes backed with a standard 5-year warranty on replacement parts and a 7-year warranty on the compressor. For even greater protection, upgrade to the MrCool Care Kit Program and enjoy extended limited lifetime system replacement—because long-term comfort shouldn’t come with surprises.

And when you purchase through IWAE, you get an additional 1-year extended labor warranty included at no extra cost, giving you even more value and coverage from day one.
