What Our Customers Are Saying

  • A-1 Refrigeration was referred to me by a friend of mine. And they lived up to their name. A-1. During one of the hottest weeks of the year, over 100 degrees for about 12 days in a row, my old system just gave up completely. The house was about 92-94 degrees during the day.

  • These are great people to work with. I called 4 businesses from the phone book. I went with A-One based on information, service and price. I needed a service contract and got one at a great price. My heat pump needed work and was repaired quickly.
