Service manager is extremely rude. He didn't like me challenging him and the installation performed by his technicians.

As usual, this exceptional business came through yet again. I called them yesterday because I had water all over my floor. They came around 1om today and quickly fixed my condensate pump. I am ALWAYS happy with this business. They are always courteous, professional and competent.
Joe went above and beyond by not only unplugging the condensate line, but also took apart my pump and cleaned it thoroughly. He didn't have to do that. I strongly recommend A to Z Heating and Cooling.

Do not use this company! Service guy came out when our wall furnace in family room went out during worst cold snap in years. Guy said it was ignitor, charged me $85 for the service call, and that's the last I ever saw or heard from this company of grifters. I called and left messages and no response EVER. This happened a couple years ago but I still feel so strongly about these shysters that when I saw their name come up during a google search I felt I owed it to other potential customers to hear what a shoddy company this is. Can't believe they're still in business!

We started having issues with our air conditioning not cooling the house intermittently. It was a difficult problem to diagnose and fix but every tech and install team that came out did everything in their power to make things work for us. Lisa in the office was nothing short of wonderful. She was extremely accommodating to our specific circumstances and was incredibly kind. I feel like her concern for the comfort of our family was almost as much as our own. Thank you A to Z, having an air conditioned home again is WONDERFUL.
