I hired Moss Mechanical to replace two AC units last month and couldn't be happier with the service and cost. After calling more than 15 other companies and getting the run around for almost three months, a friend of mine who works for the BBB told me to only use vetted companies by Dallas Pro List. My intent was to purchase one now and one later, but I was able to secure financing for them both. This included a $2500 rebate by the government I had no idea I qualified for. So give them a call and save yourself the headache and run around of people trying to rip you off and/or waste your time.
