Our furnace in our new house wasn't spreading out the heat very evenly and we had Chris come and take a look. He found that when the previous owners finished part of the basement they did not run new lines for the vents, they just tapped into the rooms above them. Chris identified that the majority of our air was being sent to rooms that didn't need it and installed a dampener to even out the house. He also raised the furnace up 4 inches to get the right amount of air flow on the return and hooked up a humidifier for us. Great work!
