I rep Fujitsu which competes with Mitsubishi units. Fujitsu and Mitsu are the best out there and you will be shocked how much heat you get out of them. You might find the regular Fujitsu unit will do better with heat where a Mitsu will have a commercial model or a more expensive hyper heat model. The standard Fujitsu will cover it.
Fujitsu General America
12RLXFW unit will work.
