Report
I had an AC issue for 2 years that none of 4 different contractors could figure out. I called Redding and I couldn't be happier with the service. Mike came out, evaluated my situation fully, gave me some advice on maintenance, and he got to the bottom of the problem WITHOUT recommending a system replace. Two other contractors recommended that to me. Redding will be the only AC company I call going forward.

Today Mike arrived on time to fix my AC and was meticulous in his evaluation of the system before moving forward with a costly test. In the process he was able to find and fix a rather subtle and not easy to see problem without doing the test, which was a significant cost savings to me. Thanks Mike!
