Had RJ heating install a new furnace and heat pump back in June 2024. They've been doing the maintenance since and everything runs great. I was very impressed with the estimate involving Julius. It was refreshing to have someone who had experience with the work come out for an estimate, instead of essentially a salesman that we got from the other 3 companies we got quotes from. The quote from RJ was the most reasonable. Scheduling the install was easy, Angie helped us out with rescheduling when something popped up, and worked to get us a different model of furnace so we'd qualify for an additional rebate (even though the Carrier distributor tries not to sell that particular model for some reason). Install was smooth, carried out by Justin and Mason. They were timely and clean. Justin was great with our small dog, who likes to supervise work being done around the house. Highly recommend! Only thing that could be improved was if they decided to become an IRA registered contractor, as customers may qualify for additional rebates, but even without the extra rebates they were still the best priced. Definitely worth getting a quote from if you're looking to have work done!

We recently had a need for a furnace quite quickly as the heat went out during the coldest weather this year. Brian came to the house to repair the furnace. We found out it was beyond repair and was emitting CO2 in the house and could of been deadly. He explained everything to us. Within the week we had a new furnace in place. Everyone from the service guy (Brian), installers (Josh and I cannot remember the others name), and Angie in the office went above and beyond to help us out. I would recommend RJ heating to anyone looking for a new HVAC system or repair of the current system. I would give them 10 stars if I could!

I can't say enough good things about this company. First contact to make the appointment was pleasant. We needed ductwork reconfigured for a remodeling project. Julius had to do some creative ductwork design to make it happen. His expertise and experience were invaluable. And, the cost was very reasonable.

We requested 4 estimates to help resolve our issue of poor heat in a room with undersized baseboard. RJ, and Julius in particular are the only ones that didn’t try to sell us a new boiler to fix our problem. We’re very glad we ended up going with them as the solution they recommended works very well and the old beast keeps up just fine!

Our old Carrier AC unit was at it's end of life and we had three companies come out to give an estimate. Not only did RJ give us the best price, but informed us about other factors that other companies neglect to tell the consumer, inflating that cost. I truly appreciated their honesty. They did an amazing job and were quick with the installation! Thank you very much!
