We had such a great experience with Air1st! They installed our new AC system and thermostat, and from start to finish, they were friendly, professional, and very thorough. The price was great, and they made sure everything was done right. We couldn’t be happier with the service and highly recommend Air1st!

I had a great experience with Air1st, especially with Joseph who handled the service. He was very professional, courteous, and took the time to thoroughly explain the situation and walk me through the options. I really appreciated his attention to detail and honesty throughout the process. He made sure everything was done correctly and didn’t rush the job. The installation went smoothly, and the system is now working great. It’s clear he takes pride in his work and wants to do things the right way. I would definitely recommend Air1st and Joseph for anyone needing HVAC work.

These folks are knowledgeable, professional, quick to respond and the best " bang for the buck" that I have found in an overpriced and almost non-compeditive $ driven market. Highly recommended!
