A-Tech technician and Brad are outstanding!!! Honest and straightforward as you can get. Our AC/furnace combo unit was about 15 or 20 years old and on its last leg. Compressor was going and we needed to make a decision before the first week of summer in the desert. It was quite east with A-Tech, they gave us multiple options and we decided to buy an entire new unit. The guarantees alone have left us with a piece of mind for years to come, which is priceless. This week of 110 degrees to 115 degrees would have been a daily stress, not if, but when would our old unit decide to take its final breath... THANK YOU A-Tech!!!
