John was great. Came early with good communication to confirm that was ok. Completed maintenance service efficiently. Helped me understand the system better and how to maintain between service appointments. He was very professional, respectful and friendly.

I finally decided to replace my 20 year old HVAC system. I got 4 competitive bids. Jason spent so much time with me explaining all of my choices. He really looked over my old system to make sure there wouldn’t be any surprises. He was right in line with a couple of other bids. It came down to how comfortable I felt trusting him. I didn’t get that with the others. Can’t say enough good things about Shane, John & John. Professional top to bottom. They didn’t waste anytime

Had multiple quotes for getting a new tankless water heating system installed. Kind of an emergency as without hot water we were in a bind. Not only did they give us a reasonable price but were able to get it installed quickly. There were a few glitches with cleanup and having to turn some stuff back on, but overall a very good job!

My furnace had a critical heating issue that I was unable to fix on my own. I called ROX and they came out just a few hours later and diagnosed the issue. Raphael was very knowledgeable and friendly, and was able to diagnose the issue. There was a parts issue on the manufacturer’s side but ROX and Raphael were very communicative and made sure that the situation was handled and took very good care of me. I would definitely use them again and would recommend for anybody who doesn’t know what company to trust.

We just had a Aprilaire 600 whole house humidifier installed in our home. Project from initial contact thru completion went exceedingly well. Would highly recommend ROX for anyone looking for fast , efficient and professionalism in a contractor.

ROX Heating and Air is my #1 go to HVAC company. I've been doing Home Inspections for 18 years and refer them to all of my clients for their HVAC needs and when my furnace started having issues there was zero question about who I was going to call! Raphael came out and quickly diagnosed my issue and was able to repair the issue within 2 days. I know I can rely on the Technicians to be honest and forthcoming and do not take advantage of my clients lack of knowledge in their system. Too many times I've had other HVAC companies try to convince my clients they needed a whole new system when all it needed was a minor repair. ROX Heating and Air has never done that to any of my clients. Would never refer anybody else to my clients!

Raphael came out to look at our furnace and he was knowledgeable, quick but efficient, and kind. We do have a heafty repair job ahead of us but he did what he could for right now to buy us some time!
