This is a great unit

I purchased the 36,000 btu model with two heads and had them professionally installed. As soon as the HVAC was completed and the unit was turned on, the system went into automode and started to blow a soft stream of warm air until it understood the different room sizes of my home. The air is whisper quiet and heats up the entire house, I live in a 3500 sq foot home. Also considering the temp around here is usually -20C and colder in the winter, this unit keeps going and going keeping my baseboard (and propane) costs way down. I can't wait for the summer heat to turn the AC functions on :-). I would highly recommend this unit and to have it professionally installed since the warranty is only valid with a installation receipt.
