We had a 25 year old boiler in our 120 year old home that needed to be replaced and there aren't many companies that do them these days. We asked our favorite contractor who he recommended and without hesitation he told us to get in touch with BJ's. One call to him and the ball was rolling! BJ was extremely professional and super honest (which is rare these days!), we couldn't be happier with the timely service and exceptional installation that was done at a very fair price!! We now have peace of mind knowing "The Boiler Guy" is just a phone call away if we need him in the future Thank you so much! (If we could rate more than 5⭐️'s we would for sure!!)

I recently had my aircon unit installed by the same company and they sent their guys over as per their check-up policy. They were fast, informative, and polite, and were on their way in less than an hour. The only regret I have is not asking for more business cards to recommend them to my peers and not offering them lemonade I had sitting in the fridge. Choose them if you live in Bloomington/Normal.

We had an absolutely amazing experience. B.J. got back to us so quickly, answered all of my questions and got us in quickly to replace our a/c unit. They were so professional, incredibly kind and got us back up and running so quickly. Highly recommend them!
