Baseline Mechanical is awesome! Answered the phone at 6:30am and the service tech was here by 9am. In the AZ Heat every minute matters and i'd highly recommend them for your residential a/c service. Cliff diagnosed quickly the part that failed, and told me the new part will come with 1 yr parts labor warranty. He gave me a very reasonable quote and even gave me a discount for local radio ad. Excellent customer service and had the parts in his truck and had my a/c fixed and cooling in about 30 min from start to finish. Call them they are that good
