Customer Satisfaction - Air 1 Heating & Air Conditioning Alan, I wanted to express my satisfaction with the installation of the new HVAC system today. I could tell an immediate difference just 15 minutes after we turned it on. Air 1 Technical Manager, did a fine job of mechanical workings of the equipment. He and his assistant worked hard, arrived on time, and were both professional and courteous. Thank you for your superlative negotiating skills with my landlord and orchestrating a difficult job that ended in success. I look forward to working with your company in the future and will recommend Air 1 to neighbors and friends. All the best,
Kim Murray
Air 1 Mechanical System Inc. installed a full heating and cooling system in our house, when our old system broke down in the middle of the summer season. We called Air 1 summer season. We called Air 1 for help. They were very efficient, very prompt, and for 1 for help. They were very efficient, very prompt, and very reasonably priced. They prompt, and very reasonably priced. They worked until 9 p.m. to make sure we have sure we have a working air condition before we face the heat of the morning sun. We highly recommend Air 1, for all your heating and cooling needs. Sincerely,

Recommendation for Air 1 Heating & Air I would strongly recommend Air 1 for anyone considering installing new or upgrading their Heating & Air Conditioning System. We had two systems installed, and both were installed on time and have been operating without any problems since they were installed. Even the county building inspector commented on the excellent quality of their work. Alan and his staff were very professional, they were always on time, they cleaned up thoroughly before leaving and their prices are very competitive.

December 17 I am writing to express my appreciation for the fine work you did in installing my new Carrier central air conditioning system. You arrived on time and finished the work in a short amount of time with minimal disturbance to our household. The quality of your work seems to be very good and I am looking forward to many years of use of our new equipment. Your price was very competitive and you seemed very knowledgeable about the Carrier products. I appreciate your openness and candor about the equipment and letting me talk directly to the Carrier representative when I had technical questions. I’d be happy to recommend you to future customers here in the Northern Virginia area. Sincerely,
John N. Barrer, PhD
