Chas Roberts started as a two-man operation. Or rather, a one man – one woman operation. Chas and Alice Roberts opened their doors in August 1942, and the business has been family owned and operated ever since. Chas Roberts has grown to become the largest HVAC provider in Arizona, having installed over 1 million systems throughout the Valley.

Chances are if you have a newer home in Arizona, we installed its first air conditioning system. Over the years, we have never wavered from the standards our founders put into place: integrity, honesty and trust. We provide quality products at fair prices. It’s as simple as that.

✓ Unparalleled technical skill and know-how.
Chas Roberts is proud to have the highest-skilled technicians in the industry; each one is licensed bonded and insured and has successfully completed the rigorous Chas Roberts Customer Service Training Program.
✓ Day or night, help is just a call away
Because A/C and plumbing systems don’t keep bankers’ hours, we happily take service calls 24 hours a day, every day of the year, including holidays at no extra charge.
✓ Quality, convenience and affordibility.
With Chas Roberts, you get it all – the highest-quality products and services, convenient online scheduling and the most competitive prices in the industry.
✓ Keeping Arizona comfortable since 1942.
Family-owned and operated for three generations, we’ve been singularly dedicated to the same mission for over 70 years: providing Arizona’s homeowners with safe, comfortable living conditions.
