I would recommend all phase air to anyone. I had a problem what I thought was my thermostat. All phase air answered their phone came to help me within 24 hours. And the professional fixed my problem was very courteous and explained everything to me. I also like the fact that they're local.

I had a great experience! Ask for Evan. He came out promptly, diagnosed my heat pump quickly and came back the next day to fix it. In the process, I learned a lot about how heat pumps work. He really took the time to explain things. Would highly recommend!

I had problem with my cooling system which was caused by the negligent work of the previous company that I had hired. Apparently, system malpractice is not rare nowadays. All-Phase sent over Evan to rescue us from our air conditioning meltdown. He was a young fellow, but sharp as a tack. He had an aire of professionalism and respectfulness which has become uncommon, as if he had stepped out of the 1950s. The reason I picked the company was because the website made it appear as if were operated by a good family. They looked trustworthy. I wasn't disappointed in my decision. My expectations were exceeded. There was basically a thicket that had grown up around the outside unit, so he had to fight his way through it, in order to get the job done. There was not one complaint. He did the job fast and well, while maintaining a positive attitude the whole time. Even the dog liked him, and "killer" doesn't like anybody. When everything was finally completed, I was pleasantly surprised by the charge. It doesn't seem proper to site numbers, but it was very reasonable, and considerably less than what I was accustomed to. I'll certainly call upon them again whenever there's a problem in the future.

They are on time and always call before arriving and follow-up after the service. Techs are very polite and knowledgeable of our heating and cooling system, and explain the work that they have performed. Five stars all the way.
