  • 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.

  • Jesus was incredible! We contacted him late evening and he was there the next morning for a repair. Crushed it and got me up and running once more! Great work ethic!! 10/10 would book again

    Matthew M.

  • Nelson and Austin are amazing! Our a/c went out on Thursday afternoon, I called Friday morning and they were out the same day to help us even though their schedule was already full! Our unit is older and they found the part we needed but it wouldn’t be in until Monday. Austin was able to do a temporary fix to get our unit up and running to help us over the weekend. They could have easily told us we needed to buy a new unit but they didn’t. Amazing trustworthy service!
