11509 W 121st Pl, Cedar Lake“So glad we went with this company to fix our AC. It went out in the midst of a heat wave, and it was rough. Willamson Heating and Cooling answered our call right away and came out to fix it super quick. They put the ac in very nicely and cleaned up around it all within a few hours. I’m very happy with their work, and they were super professional as well. 10/10 recommend“
“The best and most honest HVAC contractor I've dealt with. Very friendly and doesn't try to sell you anything. He tells it like it is. Not like the big name contractors. Family friendly. Highly recommend!“
