WHAT OUR CUSTOMERS SAY

by jan80 from HomeStars on DeMarco Mechanical Services Inc

Our A/C broke down so we called DeMarco Mechanical and they had a guy out within an hour and a half. It was an old unit so the technician recommended replacement because we were having issues with it lately. we found the pricing very reasonable and they came the next day and had it installed in no time. The A/C worked great and looked good too.
