Roberts Mechanical installs, replaces and services walk-in coolers and freezers for restaurants, groceries, convenience stores, food service operations and agricultural facilities across Central Florida. We have done commercial refrigeration alongside HVAC from our east Orlando shop since 2006. Whether you are fitting out a new kitchen, replacing a box that has reached the end of its life, or keeping an existing one running, the same repair-first approach applies.

What a walk-in installation actually involves

A walk-in is not an appliance you plug in. It is a refrigeration system built on site, and most of the cost and most of the problems are in the parts nobody photographs.

Sizing the refrigeration load, not the box. The panel dimensions are the easy part. The load depends on how often the door opens, how much warm product goes in at once, whether you are pulling down fresh stock or holding frozen inventory, and how much heat the space around it throws off. A unit sized off square footage alone will either run constantly or short-cycle, and in Florida it will do it while fighting humidity the whole time.

Where the condensing unit goes. Remote outdoor, remote indoor, or self-contained on top of the box. Each has consequences for noise, service access, ambient heat and how the thing behaves in an Orlando August. Putting a condensing unit somewhere convenient for the installer and miserable for the technician is one of the more expensive shortcuts in this trade.

Condensate and drainage. Every evaporator produces water, and on a freezer that drain line has to be heated or it freezes solid and backs up into the box. Getting the drain routed, trapped and terminated correctly is not glamorous and it is the single most common source of the ice and standing water we get called about.

Electrical and controls. Defrost scheduling, door heaters, alarms, temperature monitoring. A box that holds temperature but has no alarm on it will still cost you the inventory the first night it fails unattended.

Permits and code

A commercial walk-in is permitted work in Florida, and in most jurisdictions it is a standalone mechanical permit that cannot be rolled into a broader remodel or new-construction permit. Plan submittals typically include the floor plan showing the box location, condensing unit placement and drain termination, the electrical layout, and the manufacturer’s installation details. Exterior installations generally route to fire and electrical review as well. Inspections run in stages: electrical rough, mechanical rough, then electrical and mechanical finals.

We pull the permit and schedule the inspections as part of the job. Requirements vary by jurisdiction across Orange, Seminole, Osceola, Lake and Polk counties, so we confirm with the authority having jurisdiction before we file rather than after.

Federal energy standards also set a floor on what can legally be installed. Walk-in coolers require at least R-25 wall, ceiling and door insulation; freezers require R-32, with R-28 in the floor. Automatic door closers are mandatory on standard-size doors, strip curtains or equivalent infiltration control is required, evaporator and condenser fan motors under one horsepower must be electronically commutated or three-phase, and interior lighting must hit 40 lumens per watt or be on an occupancy timer. Reputable manufacturers build to this, but it is worth knowing what you are buying, particularly on used or auction equipment.

Replacement versus repair

Plenty of walk-ins we are asked to replace do not need replacing. Failing door gaskets, a dead defrost timer, an iced drain line, a dirty condenser or a refrigerant leak all present as “the box is not holding temperature,” and all four are repairs. Panels themselves last decades. The refrigeration equipment attached to them does not.

Where replacement genuinely makes sense is when the panels have absorbed moisture and lost their insulation value, when the box is badly undersized for how the business actually operates now, or when a system still running an obsolete refrigerant would cost more to keep alive than to replace. We will tell you which of those you are looking at, with the numbers, before you commit.

Service and preventive maintenance

Refrigeration failures are not like an office air conditioner failing. They are measured in lost inventory and closed doors. Regular service on a walk-in is genuinely cheap insurance: condenser cleaning, gasket and hinge inspection, defrost verification, drain line clearing, superheat and subcooling checks, and confirming the alarm actually alarms.

We run 24/7 emergency service for exactly the reason you would expect. A freezer that fails on a Friday night is a different problem at 11pm than it is on Monday morning.

Getting a quote

For a new installation, tell us what goes in the box, how the operation runs and where you want it. For a replacement, we would rather look at what you have before quoting, because roughly half the time there is a repair path worth pricing alongside it. Call 407-405-2658 or use the form above.
