Used RJH to repair our ice maker machine at our shop. we had another refrigeration company come our and work on the machine, they came out five different times, each time they said it need a different part, never fixed unit. James Brown from RJH came out and worked on the unit, ordered one part, cleaned they unit and ice cycles, tested unit and had it working perfectly after installing only one part. James knows what he is doing and would recommend this company for anyone needing refrigerant work done.

The entire team at RJH Air Conditioning and Refrigeration Scientific Division always does a superb job of repairing and maintaining the lab equipment at our American Red Cross facility located in Rockville, MD. Thank you and keep up the great work!!

My first experience and impression of RJH for a commercial repair was that they were very responsive, prompt, and professional. Craig, the tech sent out to our DC restaurant, was great in how he approached the job, how knowledgeable he was, and the extra time he took to explain the issues to someone like me who encountered him as he was already finished and about to leave the location. I was so impressed with Craig, that I have requested that he be our primary service person and we are already in talks with RJH to handle all of our preventative maintenance.

I had the absolute pleasure of speaking to Phyllis yesterday. We had an equipment emergency and she expeditiously arranged for rich to come the very next morning! He was quick to assess our situation and diagnose our problems which we now have a plan to correct. He was super detail oriented and figured out our issues in no time! Every thing Phyllis promised was delivered! Rich was a quick diagnostician and we will soon be signing a maintenance contract for our establishment bc I trust them fully and know that I am in kind, caring and capable hands! Thank you everyone:)

Rich from RJH has been servicing the refrigeration systems in our government facility for some time now, and his work speaks for itself. He’s reliable, knowledgeable, and handles every job with precision and professionalism. Beyond the technical side, Rich is very well-mannered and consistently pleasant to work with. He communicates clearly, respects the space and staff, and always shows up with a good attitude. It’s not easy finding contractors who check all the boxes, but Rich does. Highly recommend.

Over the years, our secure private site in Washington has required consistent service for everything from the building's chiller system down to the reach-in coolers. Following several system shutdowns due to water line issues during construction, we found RJH. After their technicians resolved the immediate problems, they recommended a preventative maintenance program and filtration systems, which has since saved us significant time and money. Now, our visitors consistently comment on the exceptional clarity of our ice. The savings we've realized through their service have even allowed us to replace equipment cost-effectively, all thanks to RJH. Their technicians take the time to thoroughly explain our options before the office provides a quote for the work. While no company is perfect, we haven't found anyone else who comes close to their level of service. Despite being highly sought after for government projects, RJH is always quick to respond to our needs. We're very grateful for their support.

These guys (particularly Steve) are awesome. We were told by multiple vendors that we had no option except to replace a multi-unit commercial AC system. Steve stopped by within 20 minutes of my call and was able to get the units back up and running. He ended up saving us tens of thousands by being honest and untold dollars in productivity that we would have lost had we had to send everyone home.

When it comes to the DC Metro area, nobody does it better. I am in the food service industry and I take RJH wherever my career takes me. Over the last 5 years Heather in the office, Rich and Terry in the field have proven themselves over and over again. They truly care about My business. Five Stars!
