Great service! We had our 40yr old furnace replaced and a new AC system put in to our townhouse. The Mr. Cool Mr. Heat crew showed up when they said they would, and completed the work in the time frame that was quoted. They left our place cleaner than when they started, and generally treated our house and family with great respect. During the entire process John, the owner, was very up front and honest with us and I felt very comfortable the whole time. I highly recommend Mr. Cool Mr. Heat.
