Chris from CMAGSHVAC was great. He was on time, courteous, very thorough and knowledgeable. He took the time to explain to me how different components work(I like to understand these things!) and what safety measures the HVAC unit provided. Needless to say, my system runs effectively and efficiently as Chris takes care of it routinely. He was also neat and clean with his work and coming in and out of the house. Before I met Chris, previous service techs would walk in with muddy shoes and leave a mess. I would highly recommend using CMAGSHVAC for all of your heating and cooling needs.
