Alex called me and told me he would arrive at my place in 20 minutes. Alex arrived on time. I met Alex outside my house and asked what exactly do you do for maintenance on an ac. Alex gave me a thorough explanation what hes going to do on the ac at my house. I must say he did exactly what he told me was going to. I was totally impressed with Alex. He did an outstanding job. He took his time and checked out the system thoroughly. I think Alex should be commended on his job performance and his attention to detail. Job well done Alex. Ty for your help.

Had our routine service today by Alex. He called before arriving and was right on time. Answered all my questions and concerns and did a great job with our routine check up! Also made great suggestions for future product that would keep the AC running efficient. I would recommend Rex Air for all your AC needs.
