Air1 Mechanical Systems was very professional and provided great attention to detail while installing my furnace, AC system and Hot Water Heater. The technician was very accommodating and hard working. He had excellent product knowledge. He was very willing to answer my many questions. I would use Air1 again and recommend them to my friends.

After having bad luck with some other vendors , it was great to get competent, friendly service. I needed someone to come out on a holiday, which they did. Technician involved me in his troubleshooting of air conditioning unit, checked with me before taking steps to repair, and gave both short term and long term recommendations. I will use them again.

Air 1 is the third A/C company we have used in two years. Air 1 found a solution to our problem, advised us that we had been given inaccurate information by the previous companies, and gave us a very competitive bid. Air 1 completed the job on time with a clean, courteous, professional staff of installers. We would highly recommend their services.

The technician, Mr. Davila, was super-responsive and on-time on a Friday evening to come and inspect our A/C unit. Explained what needed to be done and what could be done and then laid out all the costs up front to help us make a decision. Very courteous and fair! Would hire again and I would recommend to anyone for A/C service!

Great company to work

Air 1 crew are legit. Always so helpful and upfront. They are family owned and 100% dedicated to customer service and using Air 1 for past 6 years. I know several HVAC companies but always call them when we have issue with our HVAC at our home.


Called on Tuesday. scheduled next day and they arrived on time. Walk through of the issues and costs we're done without prompting and before any work was done. No hassles, Prices were fair and in the range. I'd highly recommend and will use again.
