Reeve was on time, and completed the installation ahead of schedule. He is exceptionally skilled and knowledgeable. We highly recommend Reeve and the RJ HVAC team.
Kim P. · ★★★★★ · Oct 18, 2026 Fantastic to work with, would highly recommend. Reeve did a great job on our furnace and just a really nice guy.
Carrie A. · ★★★★★ · about 2 weeks ago Friendly , professional service. Not only did they fix my gas fireplace but they took the extra time to adjust all the setting so that the unit was functioning properly and safely! And all on a Saturday!
Tim H. · ★★★★★ · about 2 weeks ago Reeve as prompt, professional and an absolute pleasure to work with. He was knowledgeable and was able to diagnose my issues quickly and immediately addressed my needs. I would highly recommend RJ HVAC and will certainly use him in the future.
