Called them to have my air compressor looked at because it stopped running. They told me a guy would come by on his way home from work. He looked at it and told me it needed 3 new capacitors. He called the shop to find out if they had them. They told him they did. He said someone would be out the next day to replace them. A guy returned next day with one capacitor. Didn't solve my problem. Never got an estimate on cost of repair. A month later I get a bill that was sent to the wrong address and I get a phone call from their attorney in Texas wanting to collect $290 for a service that didn't fix anything. I ended up settling for half because the guy did diagnose the problem. Don't think I will call them again. Ask for an estimate up front before any work begins
