Best Heating & Air Conditioning / HVAC In Cedar Lake

“Joe and Alex were fantastic. They took the time to show me the before and after photos and explain their findings. And they got the work done well before the quoted window of time was over. I couldn’t ask for better.“

“My furnace went out, I called Williamsons and they were available to come out within 2 hours to look at it. The furnace is pretty old but they were able to diagnose the problem and fix it within an hour while being honest with me about probably wanting to think about replacing the system in the future. They could have easily told me there was nothing to do and I needed a replacement now but they were extremely honest and able to buy me some time for now. He also went over estimated pricing (per my request) if I'm interested in the future. There was no pressure at all. Very honest, fast and good work! Highly recommend and appreciate!“

“Very professional, kind, honest, informative and quick to come to our home when our AC went out. Out of all the service companies I’ve dealt with over the past 30+ years, KMK has been the very best!“

“YOU CAN'T BEAT EXPERIENCE! Early October I had a company out because every couple of weeks my steam furnace would blow the 220 fuse on the electric ignitor box. I wanted it checked and cleaned. The tech came out, pulled and wire wheeled the burners, and suggested I put in a new ignitor . Once again the furnace ran till mid December and again blew the 220 fuse. The tech was a very nice young man, but I didn't want to call back the company because I thought there was more to cleaning a boiler than wire wheeling the burners. I called a friend who I new also had a couple older buildings , he gave me Marks number. Mark promptly returned my call, I explained the problem, and told him I had a picture I could send him of the ignitor control. He said no he would be out the next morning, (I think he already had a good idea of the problem).Next morning he emeditily pulled and recleaned the burners (very dirty),found that the gasline going to ignitor not tight, and removed and cleaned tubing going to pressure switch, (plugged solid).He than explained that should do it, and call him if I have any problems. The boiler running fine. Thanks Mark!“
