The deep dive on rack & co₂.
Everything we wish our customers asked before choosing a contractor.
Systems most shops will not touch
Parallel rack systems and CO₂ (R-744) refrigeration run the continuous, high-demand cooling behind supermarkets and large kitchens — and they are a genuine specialty of ours, not a service we outsource. We have hands-on experience with both traditional racks and advanced CO₂ transcritical systems, including the start-up and commissioning work most Broward contractors will not take on.
Commissioning done to spec
A rack that is not commissioned correctly wastes energy and fails early. We start up, leak- and pressure-test, verify charge, program the controls, confirm every suction group and defrost cycle, and document the result — so the system runs the way it was engineered to and you have a record of it.
Controls and defrost strategy
Modern racks live and die by their controls. Carel and Danfoss controllers, sensor drift, and defrost timing are where a lot of "the rack is not holding temp" calls actually originate. We tune the controls and defrost strategy to hold case temperatures without burning energy on unnecessary cycles.
