I highly recommend Alpha Heating and Air and would give them 10 stars if I could. After another company (Addcox) miswired my heat pump causing it to burn out (and they would not replace it) Alpha Air stepped up, found the correct size heat pump back in Massachusetts and had it flown overnight to Oregon and quickly replaced the heat pump (thanks, Michel!). Since the thermostat that Addcox had installed malfunctioned, Alpha Air got a new one, installed and calibrated it—which now works perfectly (thanks, Jason!)—and gave me tips on how to protect the new heat pump from the weather. I am completely pleased with the work they did, and the pleasant attitude of all the people with which enacted.
