"Once again Hillside Heating gave me outstanding service. During the recent cold snap (temps around 5 degrees with -13 windchill), my 2-yo furnace (recommended and installed by another provider) couldn’t keep up. Mike, the Hillside tech, thoroughly checked out the system. He found problems with the settings and improper vent positions throughout the house — careless work by the former vendor. In a couple of hours, the system was working much better with every room feeling comfortable and cozy. Thank you Mike and Hillside!"
