I used Universal Heating Air Conditioning and Plumbing for a new hot water heater installation and valve replacement. I love their service. I thought they were wonderful. They sent one person who was extremely quiet. He spent a long time working. It took him three hours in the install it, because I asked him to change some valves. He worked quietly and competently. He explained everything he was doing. He was on time. His work was great. The hot water heater is working perfectly well. I would absolutely use them again in the future.
