We had some storm damage and it affected our old air-conditioning system. We went on the internet to find someone local, and Desert Mechanical answered the phone quickly. We had a technician come who was extremely knowledgeable, and made a quick estimate to replace the unit. The estimate he gave was very reasonable. He came back on the scheduled day he said he would, and had the paperwork and everything ready. He was very well-prepared. He ended up replacing my old air-conditioner unit with the new one, and supplied me with a warranty. Everything has been working excellent ever since.
