A poorly designed refrigeration system struggles with temperature stability from the day it is installed, not because the equipment is bad, but because it was never sized correctly for the space, the product load, or the way the business actually operates.
Whether you are opening a new restaurant, renovating a kitchen, or replacing an undersized system that has never worked quite right, getting the design right from the start matters more than simply choosing a larger unit and hoping it will be enough.
Headquartered in Sarasota and serving commercial clients throughout Collier County, Hillsborough County, Lee County, Manatee County, Pinellas County, Sarasota County and surrounding areas, Miller Refrigeration designs and installs commercial refrigeration systems across Florida, including walk-in coolers and freezers, multi-case display refrigeration, and back-of-house cold storage.
Our experts calculate the actual cooling load based on product type, door traffic, ambient kitchen temperature, and required holding temperature, rather than defaulting to a standard size that may not match your specific operation.
What We Provide
The cheapest time to get refrigeration right is before it is installed. A design consult now avoids a system that fights you for the next decade.

An undersized system runs almost nonstop trying to keep up and still struggles to maintain temperature during busy service or frequent door openings.
An oversized system short-cycles, wastes energy, and can have difficulty managing humidity and frost because it cools faster than it can properly dehumidify.
Getting the load calculation right, accounting for door traffic, product load, and ambient kitchen temperature, determines whether a new refrigeration system performs reliably for the next 10 to 15 years or becomes a recurring issue from day one.
Correctly sizing a commercial refrigeration system is critical to long-term performance — it is the difference between equipment that quietly does its job and equipment that generates service calls.
Before We Specify

A site visit at your facility allows us to confirm these details instead of designing a system around assumptions or a generic template.
Common Questions
If the current unit has fought you since the day it went in, the problem is usually the original load calculation. We will measure what the space actually needs before quoting a replacement.
