Keeping any moving component operating safely and efficiently is very important. Carlson & Stewart Refrigeration’s preventative maintenance programs will help your industrial refrigeration systems continue to operate just so. Each system is different, and each system’s needs then are different which is why each preventative maintenance program is different and is custom tailored to the system, its needs, and the customer’s budget.


24/7/365 Service

The best “tool” that we offer our customers is our staff of highly trained and experienced installation and service personnel. Our technicians, pipe fitters, and welders have an average of 11-years in the industry, with vast system experience in large ammonia systems for industrial customers.

Our service department is open all day, every day, even on holidays. That’s how we are able to provide same-day service (and sometimes same-hour response, depending on location) to clients throughout Minnesota, the Dakotas, Iowa and Wisconsin.

Our warehouse and every one of our green CSR service trucks are equipped with the most commonly-needed parts for quick system repair. And if there’s a part we don’t have, we can usually get it within 24 to 48 hours.
