"Jim responded promptly to my order placed on Angie's List for the Remote Computer Tune Up & Repair Deal.  He cleaned up the computer remotely, which was running very slowly, and required frequent re-boots.  Computer is running much faster now.  Great service.  Would highly recommend.

"The service was fantastic, he arrived at the scheduled time and prepared to diagnose my A/C unit. There was a leaking problem which he was able to quickly identify the root cause and give me an estimate for the repair. The price was fair based on the needed repairs. He had all necessary equipment and was able to fix in a timely manner. I greatly appreciate the service and would definitely recommend their services."

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"Went well to this point of replacing parts. Then the United needed to have a system leak test and then needed freon put in pump. This was refused by Choice warranty. We were left with a partial repair and a heat pump not able to do it's job."

"Recommended by equipment manufacturer customer service department.
