"The house I purchased was built in the 1950's. The house had the duct work for forced hot air but was heated by oil. Ross installed a natural gas furnace, coordinated for the removal of my oil tank and installed central A/C. The quality of the work was great and so is Ross's professional manner. He and his team were very efficient. I would highly recommend."

"On one of the coldest days In January, 2024, the team arrived at our home at 9:00 am. Our 24 year old boiler was removed and the new one was installed. Thankfully, we had heat by 3:00 pm. The work site was cleaned and the installer explained all the safety features of the boiler. All went smoothly and we are satisfied with the work that was done."
