Best Heater Working in Phoenix AZ

They're great!.

Our technician, Adrian Guevara was fantastic! He was prompt, informative, completed the work in an efficient and timely manner … and was very personable and friendly! ? Would definitely recommend!

Great company to work with. I can't say enough great things about Daniel. He has gone above and beyond my expectations. I highly recommend Preferred Air.

A1 Heating & Air LLC was the only one willing to step up and take on rezoning our house and putting in two new systems. Completed all of the work in 3 days. I would recommend them to anyone that needs HVAC work!

I live on a rural, dirt road that has a 25 mph limit. One of their company vehicles flew by my house going literally 70. I see there is another review that complains about a company vehicle driving bad. I think I would second guess hiring them considering how unprofessional and dangerous the idiots they send out are.

We called Semper Fi to check out our old failing system. Scott came to inspect and gave us a fair, accurate, and honest assessment. We decided on a new heat pump and it was installed within two days! The crew that came to our home was respectful and cleaned up very well. They did a great job everything runs properly no problems. Scott even stopped by on the day of install to check that everything was going smooth. I highly recommend Semper Fi they took great care of us.
