Walk-In Cooler Repair Needs in McKinney Restaurants and Kitchens

The shops and restaurants around the Old Collin County Courthouse, which was built in 1875 and remodeled in 1927 and now houses the McKinney Performing Arts Center, make the downtown square one of the busiest dining areas in the city. Square-side kitchens are usually tight, and their walk-ins often fill an old back storeroom, with the condensing unit mounted in whatever corner, alley or roof spot was left. Limited airflow around that unit makes a box run longer during hot months.

Event weekends and performances on the square bring sudden spikes in traffic, and walk-in doors open far more often on those nights. Watch for doors that do not close on their own, torn gaskets, water under the box and ice forming on the evaporator coil. Read a thermometer inside the box during service, because anything above 41°F breaks the FDA Food Code rule for cold holding. If the box is warming, keep it closed and move critical items. Leave anything involving refrigerant or electrical testing to a refrigeration technician.

Yes. We serve restaurants and cafes around the square, on streets such as Louisiana, Tennessee, Virginia and Kentucky. Downtown condensing units are often reached by roof hatch, alley or back door, so say which applies, give us the box temperature now and name your peak hours, and we will time the visit to stay clear of service.

Yes. Chestnut Square Historic Village, just off the downtown square, hosts a weekend farmers market, and the businesses that prepare or store food for it may rely on a walk-in or a small cold room. We can diagnose and repair those boxes. Let us know when your heavy prep days are so we can work around them.

That usually means the system cannot remove heat as fast as it comes in. Frequent door openings, a door that does not seal, a dirty condenser coil or a struggling evaporator fan are the common causes. Check the gasket and the condenser first. If the box still warms during busy hours, a technician should check the refrigeration system.
