Purchased a Lennox XP21 about 3 years ago. Bob's technicians provided an outstanding installation. At one point there were 5 technicians working at the same time. My home is more comfortable now than ever before and my electric bill dropped by about 40%/month for ever month for the next 12 months. Recently, a routine maintenance check by Bob's detected a small refrigerant leak in condenser. Condenser was replaced at no cost to me. If I live long enough, I will buy from Bob's the next time I replace my system.
