They were very courteous prompt professional, and clearly experts in their field. Al, my salesman, was very knowledgeable and helpful even with financing. he understood the needs of my unusual style home. He asked me where I wanted the condenser. He walked me through the steps and options to be sure i was okay with it. He then scheduled another home visit with his colleague,Eric, who was the technical person for the project. They even asked me where I wanted the ducts, although they had suggestions. The job went very smoothly. They cleaned up their mess and left the house the way they found it. I was called the following week to see if I had questions or problems. They are very organized, and did a fabulous job. It was worth the wait. They are booked for many weeks out. I highly recommend this company and am so glad I choose them over several other estimates from other companies. I could tell they were the most knowledgeable about this type of work.
