We have worked with Summit Heating & Air Conditioning for a couple years. They have replaced a motor on one of our units and fixed a furnace drainage issue we had. Their repairmen are police, nice, and professional. Their pricing is pretty reasonable and we really have no complaints. They are super responsive and call back to make sure you are satisfied with their work. Just recently they came back free of charge regarding a sound we heard, which turned out to be unrelated, but never the less their customer service is great.
