Recently I had no heat from my Mitsubishi Ductless Heating system during the snow storm. I phoned Carefree Air and they walked me through a few things to check before they sent someone out. I found that the outdoor unit was covered with snow, not allowing the unit to heat properly. They instructed me to pour hot water on the unit to defrost the snow and ice. Shortly after my room was warm again.I just wanted to thank them for getting my heat back so quickly and saving me the cost of a service call with a little old fashion customer service. This company really cares.
