Behzad was referred to us by another contractor and he was great. He fit us into his extremely busy schedule, diagnosed our problem and did the job within days. Unfortunately the unit was not repairable but Behzad did his best to find us a cost-effective replacement. He spent extra time mounting the unit on the house to keep it off the ground so it would stay clean, but it caused too much vibration in our older home so he came right back in a few weeks to put it back on the ground at no charge. Both Behzad and his assistant were quick and cheery, and are a credit to their profession.
