About RJH

We’re a division of RJH Air Conditioning & Refrigeration Service, born out of the need for emergency equipment during service calls. We’re not another “rentals company.” We’re a trusted mechanical contractor that provides rental equipment. Our commitment to excellence, expertise, and reliable service is the foundation of our stellar reputation. We provide HVAC, refrigeration, commercial kitchen, and laboratory equipment essential for our clients' operations. By choosing us, you can rest assured that you are partnering with a company that prioritizes customer satisfaction and has a strong culture of teamwork and integrity.  

Our eclectic rental inventory fits our clients' needs, not industry expectations. You’ll find an assortment of portable air conditioners, commercial cooking equipment, and refrigeration equipment, including our custom-built portable walk-in coolers. We pride ourselves on being the go-to rental house for big dreamers and boundary pushers. If you need an unusual solution, please call. 

Our delivery technicians and operations staff are experienced with the unique needs and requirements of the industries we serve & our specialized equipment.  We know how to calculate the load needed for supplemental air conditioning in server rooms, how to deliver to historic buildings with stairs at all entries, and adapt power to make the equipment operate where you need it.
