    Met with 4 different contractors regarding the replacement of our furnace and air conditioner. Really got a good feel for what equipment would best serve our needs after Logan explained a few choices and price ranges, right at our kitchen table. Logan wasn't just giving us a sales pitch; he was describing what he was personally going to do the next day. Logan and Shawn arrived right on time, protected the stairs and carpet, carefully removed the old equipment, and professionally installed the new equipment. What a pleasure dealing with people that do what they say they are going to do, and actually exceed expectations. Thanks Much, Great Job!
