“These guys are fantastic. They have replaced our original furnace, central air & recently hot water heater & have been very happy every time. Furnace change was middle of winter & was done so quickly we didn’t lose 5 degrees in the house. They had replaced our original complete central air unit which worked great for 4 years. On year five we noticed it wasn’t cooling as well as before. Called Preferred Heating & Air about it, they were out right away to inspect it & found the unit had failed & replaced right away. Always extremely impressed with their professionalism, fair price and commitment to service after the purchase. You will not be disappointed.“

“We called H.A Thompson and sons to come and look at our water heater. Another company had installed it on 8/8/23 before we bought our home in November. Once we moved in our hot water heater gave us trouble from the jump, it seemed like once a month we were having to turn it back on as the pilot light and indicator light would completely go out. I called the original company to come look at it since they had installed it. The other company was only in our house for about 2 minutes before saying it was working fine and there was nothing they could do. Frustrated I called H.A Thompson and sons, they came that day and the gentleman was able to diagnose the problem within 20 minutes and fix it that day. He took the time to work with the hot water tank to see what was happening and educate us about potential causes. We could not ask for better service! We will be using H.A Thompson for all of our future needs. This company truly cares about the quality of their work and empowers their customers with education.“
