I have had a relationship with Nicholson's Heating & Air for a very long time, beginning from when it was just a one-man operation out of the back of pickup truck. I own thirty two rental properties, and John Nicholson and his staff keep them functioning perfectly at a moderate cost. They are always there when I need them to be. They're very easy to schedule with, they're prompt and responsive, and their technicians are professional and efficient. This company has consistently provided me with excellent service through the years and I am a very satisfied customer.
