Everything was good except condensation line was short. Fortunately, the Blueridge (Alpine (same as Mr Heater)) came with some condensation line so that I could put them together. Then, the high pressure line, mating to the inside unit, leaked. Had to buy a nitrogen tank and regulator, but could not find the leak ($130). Hired a HVAC contractor and he had to re-flare the line, and refill the refrigerant ($120).See full review
