RJR Radiator, Inc.

RJR Radiator, Inc. has anchored its operations in Cincinnati since 1969, building a legacy spanning over five decades in heat exchanger and cooling system repair. The shop, helmed by founder Ray Trammel alongside service manager Wayne Petrey and Jeff Trammel handling sales and service, maintains a 4.8-star average across 72 Google reviews, a volume that speaks to consistent performance. Serving the entire Tri-State area including downtown Cincinnati and surrounding Hamilton County, this family-rooted business welcomes both walk-in retail customers and large industrial accounts requiring heavy-duty heat exchangers, shell-and-tube bundles, and compressed air charge coolers.

What distinguishes RJR Radiator from typical corner garages is their breadth: they operate as one of the larger shops of their kind in the Greater-Cincinnati area, tackling industrial-scale projects alongside everyday automotive radiator repairs. Their expertise spans oil coolers, water coils, and complete heating and cooling system overhauls for equipment ranging from passenger vehicles to commercial machinery. The shop also maintains a full automotive air-conditioning service line, handling modern refrigerant systems in cars, light trucks, and industrial rigs alike. This dual-market capability, retail and industrial, allows them to source parts and diagnose issues that smaller shops simply cannot accommodate.

Customer stories illuminate why reviewers repeatedly mention Jeff and Joe by name. Travis Keller described how his SUV began leaking coolant on a trip into downtown Cincinnati, forcing him to arrange a tow and seek same-day help. Jeff and Joe not only repaired the improperly connected hoses but proactively identified a failing water pump, sourced a replacement, and had him back on the road within hours, salvaging a planned vacation. Adam Mineer appreciated transparency: rather than recommending a $400-plus replacement, the team flushed and repaired his radiator for $100, proving honest assessment over upselling. Matthew Ruggles has relied on their craftsmanship for over two decades, a testament to lasting relationships built on dependable work.
