Peterson Heating & Cooling has excellent service. They always do a great job maintaining my air conditioning and heating units. The technicians always come out promptly when I call them. If it is an emergency, they come out within the hour. They are very competent, knowledgeable, and pleasant to work with. They do what they say they will do and get the job done. I have not had any problems with their service and am happy with their work. Their pricing is reasonable for the service and I will continue to use them.
