This past summer GreenMark upgraded our home for energy savings. We have 2 HVAC units, one for each floor. During the summer, we normally set the upstairs to 80 degrees during the day and the AC turns on about noon time. Now after GreenMark did their upgrade, the outside temperature needs to be over 95 for the AC to kick on late in the afternoon. In the past when the nights get down to the 50’s or 60’s we would open the windows, then we would close them when in the morning when it starts warming up. The AC normally is not turn on until middle of the afternoon on the first floor. Now after GreenMark did their upgrade, we have to leave the windows open in the morning so the house can warm up and not be 10 to 15 degrees colder than outside. Our perceived energy savings has been amazing. We are waiting a few more months to check out our gas and electric bills. Mark worked with us to plan all the work. The crews showed as planned. They were very friendly and respectful. The work areas were cleaner when they left than when they started. It was an all-around great experience.
