I contacted A/C Service Masters on a sweltering Sunday in July and left a message that our AC went out. I got a call back within two minutes (not an exaggeration). The service technician responded quickly, and he diagnosed the problem right away, and our AC was back online immediately. The technician then stayed a little longer (on a Sunday no less) and provided some good advice on AC maintenance and such. Everyone I spoke with was incredibly kind and professional, and their response was amazing. I can’t say enough good things about the company and our experience with them. Five stars for sure.
