Couldn't Be More Impresses
“We recently worked with R&R and couldn't be more impressed! Their team was professional, responsive, and highly knowledgeable. They quickly diagnosed the issue with my refrigerator and provided a timely and effective solution.”

Ahmed H.
Working Like It's Supposed To
“Our AC was running nonstop, no matter what the thermostat said. They came out, checked the wiring, and found a stuck relay. They swapped it out, and now it shuts off like it’s supposed to. Not something I would’ve caught on my own.”

Airah K.
Remarkable Responsiveness
“The R&R team is great! Their responsiveness is truly remarkable; you never have to wait long for a reply. They value their clients' time and prioritize delivering results promptly. I highly recommend them to anyone looking for a reliable service.”

Claudia P.
Courteous & Professional
“From start to finish, they were helpful with advice and recommendations, and the installation crew was courteous and professional. We'll now be using them for servicing our retail merchandisers, too.”

Martin T.
Excellent Job
“We had R&R come to our workplace to support us in repairing a refrigeration unit, which needed to be fixed for use that evening. They diagnosed the problem, got the unique parts required, and completed the job. Excellent job.”

Mike R.
Responsive After-Hours Service
“Working with Mary and Matt was such a relief. They didn't hesitate to jump in after hours to get our customers' refrigeration equipment back online and running. It is rare to find a team this responsive and willing to go the extra mile.”

L S.
Couldn't Be Happier
“We couldn't be happier with the service provided by R&R! They installed two refrigerator units for our fresh cut flowers, and the quality is outstanding. The units keep our flowers at the perfect temperature, ensuring they stay fresh and vibrant.”

Scott V.
Fantastic Experience
“I’ve had a fantastic experience with R&R Refrigeration & Air Conditioning, Inc.. From the very beginning, their team demonstrated professionalism, clear communication, and a genuine commitment to delivering great results.”

Shyann P.
8-Year Customer
“I've been doing business with R&R for about 8 years now. They are beyond professional and respond quickly. I've called during the weekend and they will respond. R&R is upfront about the time it will take for repairs to be made.”
