Question about Mitsubishi MS12TN Air Conditioner
I am experiencing a similar problem with my Mitsubishi slimline MSH09TW unit; about 4 years old; It use to give us very hot air now it is giving some what hot air; northeastern USA current temperature about 15F. You think frigid weather in Cranbury NJ could be responsible or some thing else is going on. Please help me if you have some time and knowledge about Mitsubishi heat pumps. Sincerely, DSS

Thinking of purchasing, I browsed the mitsubishi slim web-site, and noticed they tout the A/C features. TV advertisements lead us to believe the units operate as regular ductwork heat exchangers that include a heating unit built into the exchanger. That does not seem to be the case as they suggest hooking the unit to your existing gas or electric heating unit, and also hook you up to purchase heating units.

I have the same problem. In heat mode air comes out at room temp, not heated. Unit is set to 72 degrees and room temp is 65. I have also tried setting the unit to 90 and still get not heat.
