"Our furnace stopped working, bad news. Mike was here quickly, and fixed the unit we have so we again would have heat! He explained what problems we were having and what we can do in the future to limit additional problems. Very knowledgeable, professional and personable! Our hero for the week!"

"The whole process was professional. From the initial call to completion of the project they were clear on what needed to be done and followed through with what they said they would do. They even worked on one small area that they weren't required too. Although no mold was present in the area there had been a little water damage there so they cleaned and sealed it to make sure. Their pricing was in the middle of the estimates I received but I decided to go with them after reading some reviews as well as the professional attitude they exhibited toward the estimate.
