  • William's Air Conditioning and Heating recently completed a replacement of my furnace and air conditioning units and thermostat. William did an outstanding job and was always available to give me updates and answer any questions during the installation. He made sure everything was completed to my satisfaction and in great working order. William is always available to answer questions and to service your unit should any issues arise. The Williams Co. will always stand by you whenever you need them. - Albert A.

  • Just wanted to express my appreciation to Williams Air for their prompt, courteous, reliable and expert service that they provided. I was referred to Williams Air by a friend who rated there the service as top notch in ac repair industry. My house was close to 90 degrees and unbearable. They responded to the call in the middle of the night on a Sunday night and arrived within an hour’s time. My ac unit has been working great since they repaired the unit. They are my go-to company when I need an AC company in the west valley. If I ever have any issues again, I would definitely recommend them to anyone. Awesome response time and excellent service with affordable rates. - Jordan M.

  • I own a property management company in Mesa - We have properties over the whole Metro Phoenix area. I have used Paula with Williams Air for years! She always answers or returns my calls promptly (even on weekends and nights). The staff is always professional with the Residents; and they report back to us if the Resident caused damage or isn't changing the air filter! I strongly recommend Williams Air. - Diana C.

  • The staff at Williams Air Conditioning and Heating are top notch. I needed a new split unit and Luis and Paula helped me every step of the way. They were honest, explaining all the different types of units I could choose from and what size I needed for my size house. They installed my unit on a Saturday. They took great care on the installation testing everything to make sure it all worked. They kept everything clean while working, explained everything they were doing so I would understand and gave me great advice on filters and maintenance. They are my go to company. I have recommended them to all my neighbors as well. - Michelle's Hobby Haven

  • Williams AC is top notch, I recommend you call them. My AC quit working on a Saturday when it was 115 degrees. Paula was very friendly when I called, and she had William call me back in less than 5 minutes. He was able to tell me what was wrong and diagnose the problem over the phone. Very smart and very helpful. I will call them next time I need service. The best in the Valley. - Jason H.
