Best Heat And Energy Recovery Ventilation in Phoenix AZ

They were absolutely the best! I called - in panic mode - and they walked me through resetting my thermostat. I highly recommend doing business with SG Mechanical.

We have used Alien AC several times now for our annual AC cleaning and check-up, as well as for duct and platform sealing. They have always been responsive, very fairly-priced, friendly and done quality work. One of their techs, Jeremy, in particular has been fantastic. (Request him if he's available!)

Also, although our AC units do not yet need to be replaced, I called several companies for estimates, and Alien's was by far the best. Definitely worth keeping them in mind for new installations, too.

Tyan performed a follow-up visit scheduled by Larson Air to make sure the unit they had installed was working smoothly in the cold weather. He notified me of his arrival time, was polite and clear about his task, and wore booties in the house. He then let me know all is well. Thanks, Tyan!

Frank and crew did a exemplary job installing a compressor at my home in a extremely timely fashion in the heat of July.Have been using for 15+ years and have found to be extremely knowledgeable and the best AC service in Az.
