Report
I moved in to a new house with a furnace installed by RJ HVAC. The furnace has died 3 times throughout the winter and is now leaking. I just spoke with the owner and he yelled at me. I haven't even dealt with the company I was just looking to see if we could schedule a service. I would literally rather leave a 1 star review and pay to fix it then deal with whatever that was.

The team at RJ heating was absolutely phenomenal. From Julius coming out to quote how much the project was going to take, to the team finally coming over and installing the a/c--I can't speak enough good things about them. We initially planned on installing the a/c towards the end of last year, but we couldn't make it work with the team's schedule due to all the furnace repairs necessary. As promised, I got first priority this year and they came through. They even helped me with closing up an additional vent in the basement, at no additional charge. All in all, would definitely use them again! Don't hesitate. Reach out to them!

I would give RJ heating 100 stars if I could. I have been using them for over 25 years and have made tons of referrals. My friends and family that have used them have also been so happy with this choice. Many get multiple estimates and RJ heating is always chosen. Not only is the quality of there workmanship excellent but their installers are friendly and informative. I have used them on my personal residence in Brookfield as well as my rentals all over Milwaukee and West Allis. They have saved me many times. They really are the best!

The service was great they were on time and was great at teaching me about the system. Especially how to change the filter and the frequency it needs to be changed. They will definitely get my business if I decide to put in central air. Great business to work with.
