Commercial Refrigeration Design & Installation

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.

Key Takeaways

  • A system that never holds temperature properly is usually a sizing problem from day one, not bad equipment.
  • Load is calculated from product type, door traffic, ambient kitchen temperature and required holding temperature — not square footage alone.
  • An undersized system runs almost nonstop and still struggles during busy service or frequent door openings.
  • An oversized system short-cycles, wastes energy, and struggles with humidity and frost because it cools faster than it can dehumidify.
  • Getting the load calculation right determines whether the system performs reliably for 10 to 15 years or becomes a recurring issue immediately.

Sizing Matters

Why Sizing A System Correctly Matters

Undersized: Never Catches Up

An undersized system runs almost nonstop trying to keep up and still struggles to maintain temperature during busy service or frequent door openings.

Oversized: Frost And Humidity

An oversized system short-cycles, wastes energy, and can have difficulty managing humidity and frost because it cools faster than it can properly dehumidify.

The Variables That Actually Matter

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.

Correct Sizing Is Long-Term Value

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

What We Need To Design A System Correctly

Before Miller Refrigeration recommends equipment, our Sarasota-based experts evaluate:

  • The space available
  • The type and volume of product being stored
  • How often doors will be opened during service
  • The ambient temperature of the surrounding kitchen or storage area
  • Any code requirements specific to your business type

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

Installation & Design FAQ

How do you decide what size refrigeration system I need?
We calculate load based on the type and volume of product you're storing, how often the unit's doors will be opened, the ambient temperature of the surrounding space, and your required holding temperature — not just the square footage of the room.
Can you design a refrigeration system for a renovation, or only new construction?
Both. We work on new construction projects as well as renovations and upgrades to existing refrigeration systems that have outgrown a business's current needs.
How long does a typical walk-in cooler installation take?
Timelines vary based on project scope, equipment availability, and any construction or permitting requirements involved, but we'll provide a specific timeline as part of your project quote.
Do you handle the permitting process for new refrigeration installations?
Yes. We coordinate permitting as part of the installation project.

System Never Quite Kept Up?

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.
