We moved to Arizona 6 years ago and because our builder used Chas Roberts, we hired Chas Roberts to do the heating and air conditioning maintenance and also to service our water heater when needed. We have been 100 percent satisfied with the customer service we have received! Yesterday, at 6:30 p.m. we noticed we had no hot water and could not get our pilot light to stay lit. I got on line and was able to schedule a service call this morning at 7:00 a.m. What is amazing is that yesterday was a Saturday and not only were they able to come to our house to help us, but there wasn't an extra charge for it being on a Sunday! The tech who came to our house was polite, professional, and friendly. I see so many negative ratings for Chas Roberts and decided to share another point of view since we have been 100 percent satisfied for 6 years! I highly recommend Chas Roberts!!!
