Walk-in cooler installation covers planning the site, sizing the box and refrigeration, preparing power and drainage, assembling the panels and door, setting the condensing unit and evaporator, piping and charging the system and testing it before food goes in. Call with the size you need, where it will go and how you will use it.
A new walk-in is a long-term investment for a restaurant, store, school, church, farm or home. In Hattiesburg heat and humidity, a box that is sized, sealed and set up correctly will run for years with far fewer problems than one that was rushed in.
What installation includes
- Site visit and planning. Measure the space, check the floor, doors, ceiling height, power and where the condensing unit will go.
- Sizing. Work out the box size and refrigeration capacity from your daily load, door use and the conditions around the box. See sizing and load calculation.
- Floor preparation. Level the floor, add insulated floor panels or confirm the slab is suitable, especially for freezers.
- Box assembly. Set and lock the panels, seal the seams, hang and adjust the door, and fit the inside release.
- Refrigeration. Mount the unit cooler, set the condensing unit, run and insulate the lines, and connect the drain.
- Electrical. A qualified electrician provides a dedicated circuit and disconnect sized to the nameplates.
- Startup. Pressure test, evacuate, charge by weight, set the controller and defrost, and pull the box down to temperature.
- Handover. Walk through the controls, alarms, door care and cleaning, and leave the settings and nameplate details on file.
Choosing the right setup
| Decision | Things to weigh |
|---|---|
| Cooler, freezer or combination | What you store and how much. See cooler vs freezer. |
| Indoor or outdoor | Space inside, weather, roof and pad. See indoor vs outdoor. |
| Self-contained or remote | Kitchen heat, noise, access. See self-contained vs remote. |
| Panel thickness and floor | Freezers need more insulation and a proper floor |
| Door options | Size, closer, strip curtain, window, heaters |
| Controls and monitoring | Electronic controller, alarms, data logging |
Preparing your site
- A level, solid floor or slab that can carry the loaded box.
- Clear space around the box for assembly and service access.
- A suitable, ventilated spot for the condensing unit with room for airflow.
- A dedicated electrical circuit, arranged with an electrician.
- A drain route for defrost water.
- Delivery access for panels and equipment.
- Any permits or approvals required by the city, county or landlord.
Installing in Mississippi conditions
Heat and humidity make sealing and sizing more important here. Seams and the door must be tight, the condensing unit needs open air and shade where possible, and the system should be sized for the hottest afternoons, not an average day. Outdoor boxes need a weather-rated roof and a pad that drains. Surge protection is worth considering in storm season. See surge protection.
Replacing an old walk-in
If you are replacing a failing box or system, plan where food will go during the changeover and how long the area will be out of use. Sometimes the old box can stay and only the refrigeration is replaced. See repair or replace and upgrades and retrofits.
After installation
Keep a temperature log for the first weeks to confirm the box holds temperature through busy periods. Book the first maintenance visit within the first year, and keep the startup records with the equipment file. See the maintenance guide.
What to tell us when you call
- What you will store and roughly how much each day.
- The space available, indoors or outdoors, with measurements if possible.
- Cooler, freezer or both.
- The electrical service available.
- Your timeline and whether an old box is being replaced.

Installing walk-ins across Hattiesburg and nearby towns
We install walk-in coolers and freezers for restaurants, stores, schools, churches, homes, hunting camps and farms in Hattiesburg, Petal, Oak Grove, West Hattiesburg, Purvis and Laurel. Outdoor boxes here need weather-rated roofs and pads that drain, and every condensing unit needs open air in the summer heat. We plan for both. Call to talk through the size and site.
