"My project involved an emergency service call as I had a problem with my oil furnace in the basement. James responded immediately and was at my house in a few hours. The parts needed were no longer available; however, the company did a great due diligence search for the needed part. The work was done expertly, neatly, using the least expensive method. I would highly recommend this company for their honesty, integrity and quality workmanship."
