Trying to decide which brand of heat pump i want to go with.
Based on experience and intimate knowledge, which brand uses the best quality of materials? What about an all aluminum unit? Most of the units I have seen use copper coils an a galvanized housing. Isn't it a big no-no to mix copper and galvanize? Electrolysis? I understand there is probably not a normal pathway, but what happens when the evaporator ices up?
