Newman Air installed a new hvac unit and I considered the work and the service to be exceptional. I…read morewent on vacation for 1 week and when I returned ... water was trickling down the walls, a large water stain was on the ceiling and the baseboards were swollen and warped. Newman sent the same men out (the men who did the installation) and they discovered the problem. incorrect sized tubes were used, resulting in the leak. Two of the men apologized saying "we are better than this". When I called the Newman office, I spoke with the receptionist and asked what to do and was told to call my insurance. She said that Newman was not at fault and the men (who explained the error to me and apologized and admitted fault) had told her differently. I decided to let my insurance handle it, but Newman did not contribute any financial help and did not admit any error. To me that is UNETHICAL, UNPROFESSIONAL and UNFAIR to the customer who placed faith and MONEY in them. NEVER AGAIN.

We were not concerned they were new because it is part of Mr. Electric, who we use and trust, and pricing is very good compared to other small type businesses. Their customer service model carried over to All Systems Go! I recommend their value, and quality. Use them, you will not be sorry! Rich Oliver

Found a leak from the main floor dripping from the ceiling of the finished basement on a Saturday…read moreafter 4:30 pm. Contacted my regular plumber (not Cox) and found out he was out of town on vacation. Finally called Cox after 5 pm. Was pleasantly surprised when he answered the phone. He had other jobs already scheduled but was able to come by on Sunday afternoon. (I had shut off everything I could think of so the leak had stopped. Was afraid it was the toilet by the kitchen.) He was able to arrive an hour earlier than he expected which was great. Long store short... he was able to diagnose the actual problem (wasn't the toilet) and the issue was resolved. Very professional, very knowledgeable, very personable. Nice guy and the cost was actually less than I expected for an emergency weekend plumbing call. Hope I never need a plumber again but I would definitely use Cox Plumbing again.
