Chiller Technology Services

Chiller Technology Services operates as a commercial and industrial HVAC contractor in Hamel, Minnesota, holding a 5.0-star rating from a single verified client review. The company was founded in 1987 by Ernie Duffney and maintains master licensing, insurance, and bonding along with refrigerant reclamation and recovery certification. Their service radius extends to all areas within a two-hour drive from Minneapolis, positioned to respond rapidly to emergency calls across the greater metro corridor.

What distinguishes this contractor is their specialized background with large-scale cooling systems, notably Ernie Duffney originally commissioned Carrier chillers for the Metrodome stadium as a technician in the decade preceding the company's founding. The team handles equipment exceeding 1,000 tons in capacity, including centrifugal chillers, absorption units, and packaged rooftop systems. They maintain around-the-clock availability year-round and offer non-destructive eddy current tube testing alongside Oil sampling and lab analysis for preventive maintenance. Their Certified Welder credential supports custom installation requirements that smaller residential-focused firms cannot fulfill.

Service philosophy centers on comprehensive project management from installation through long-term maintenance contracts. Technicians assess existing infrastructure before recommending replacement, prioritizing repair over unnecessary equipment exchange when feasible. The company performs water-side maintenance including brush cleaning, acid cleaning, tube leak testing, and plugging for condenser and evaporator bundles. For facilities requiring system upgrades, they handle heat exchangers, glycol systems, and make-up air units with coordinated engineering.
