We have had the opportunity to utilize First Call Heating & AC for multiple properties and have found that this company embraces a philosophy of professionalism, trustworthiness, quality and hardwork. We have found the company/personnel be honest in bidding, expedient at diagnosing and excellent at providing quality repair to our aging systems. Installation of new product has gone smoothly. Truely competent, efficient and experienced in the heating and a/c field, hats off to the dedication to excellence! It is wonderful to find a service company that actually arrives at it's appointment time. A+++
