A walk-in cooler that creeps above safe temperature overnight can mean a whole day of produce, dairy and prepped food that has to be logged or thrown out before you open. Wilson & Myers handles walk-in cooler repair across Denver Metro on both sides of the wall: the condensing unit, wherever it is mounted, and the evaporator, door and panels inside the box. Our EPA-608 certified technicians measure box temperature and system pressure before recommending any part.
We serve restaurants, bars, breweries, grocery stores, hotels and schools, with fast response seven days a week.

A walk-in that stops cooling is the most urgent call we handle on these systems. The usual causes are dirty condenser coils on the condensing unit blocking heat transfer, or a failed evaporator fan motor that stops cold air circulating inside the box. A refrigerant leak in the sealed system and a failing compressor that can no longer hold operating pressure produce the same result.
A faulty TXV restricting refrigerant flow produces the same symptom with the unit appearing to run normally. We measure actual box temperature and system pressure before recommending any part. Book online to schedule a diagnosis.
Cooling system diagnostics
A walk-in cooler that won’t hold a steady temperature points to a control system fault rather than complete refrigeration failure. A thermostat that cycles the condensing unit off too early, a temperature sensor reading incorrectly, or a defrost timer running cycles too frequently are the most common causes. On walk-in coolers with electronic controls, a control board fault that interrupts the refrigeration cycle produces the same result. Temperature fluctuation combined with moisture on the walls confirms warm air infiltration through a failed door gasket or damaged panel.

Compressor repair is the most serious single component call on walk-in systems. A compressor failure leaves the box with no cooling capacity. Signs the compressor is failing before complete failure: the unit runs constantly without reaching temperature, short-cycling every few minutes, or the condensing unit runs hot and trips the overload protector.
Short-cycling on a walk-in cooler almost always points to a refrigerant leak reducing system pressure. We always diagnose the root cause before recommending compressor replacement: a new compressor installed into a system with an unresolved refrigerant leak will fail for the same reason.
Condensing unit service
Door repair is one of our most frequent walk-in cooler calls across Denver Metro Area. A door that doesn’t seal properly allows warm, humid air into the box continuously, raises temperature, causes condensation on walls and product, and forces the condensing unit to run constantly. The most common cause is a worn door gasket losing its seal.
A failed door heater (the anti-sweat heater in the door frame) lets frost build around the opening, and a broken door sweep at the bottom leaves a gap. Gasket replacement is a routine repair on all major brands. Book online to schedule door service.

Door gasket replacement is the single most common maintenance repair on walk-in coolers. Gaskets degrade from constant traffic, cleaning chemicals, and thermal cycling. A failed gasket allows warm air infiltration that raises operating costs, accelerates compressor wear, and causes condensation inside the box.
Test it by closing the door on a sheet of paper: if it slides out without resistance, the gasket has failed. Replacing it is a straightforward repair on all major brands.
Evaporator repair covers the evaporator coil and its associated components inside the box. A failed evaporator fan motor stops cold air distribution even when the refrigeration system works correctly: the coil gets cold but the air doesn’t circulate. A frozen evaporator coil from defrost system failure blocks airflow entirely.
A cracked or leaking evaporator coil loses refrigerant from inside the box and requires sealed system work. We access and repair evaporator systems on all major walk-in brands and condensing unit configurations across Denver Metro Area.

Floor repair is structural work that affects both insulation performance and food safety compliance. Walk-in cooler floors take the heaviest daily abuse of any component: heavy carts, standing water, chemical cleaning, and temperature cycling all degrade floor panels over time. Cracked or soft floor panels lose insulation value and allow moisture infiltration into the panel foam.
Water under the floor panel also creates mold and sanitation issues. The fix typically involves replacing damaged floor panels and resealing joints. Health inspectors flag damaged walk-in floors: address floor damage before the next inspection.
Water inside or under a walk-in cooler almost always comes from the defrost drain system. When the drain pan clogs with debris, meltwater from defrost cycles overflows onto the floor or leaks under the box panels. A blocked floor drain outlet is the second most common cause.
Water pooling on the floor right under the evaporator confirms a drain pan overflow rather than a refrigeration system problem. We clear and test the full drain system on every walk-in cooler call.
Different sounds point to different components. Loud clicking from the condensing unit: compressor start relay failing. Grinding or squealing from inside the box: evaporator fan motor bearing failure. Rattling from the condensing unit: loose panels or fan blade contact.
Continuous loud humming: compressor overworking from dirty condenser coils. Banging at startup: liquid refrigerant slugging in the compressor, typically caused by a TXV fault. A walk-in cooler that sounds louder than usual almost always signals a component approaching failure. Book online before the noise becomes a complete breakdown.
Wilson & Myers also repairs standard commercial reach-in refrigerators. Reach-in units run the same refrigeration systems as walk-in coolers but in a smaller footprint. Most common issues: door gasket wear from constant traffic, evaporator fan motor failure, condenser coils clogged with kitchen grease, and defrost heater burnout.

Dirty condenser coils, a failed evaporator fan motor, a refrigerant leak, or a failing compressor are the most common causes. Walk in cooler not cooling combined with ice buildup on the evaporator confirms a defrost system fault specifically.
Walk in cooler door gasket replacement is typically needed every 2-4 years on high-traffic units. Check the gasket monthly: if the door on a paper sheet test slides out easily, schedule replacement before temperature and energy costs climb.

Amazing service 10/10 would recommend!!!!! The team were very professional and removed and hauled away my dishwasher with ease.
Fast prompt service, fixed out dryer very quickly. Friendly and reasonable prices. Would work him again anytime.
Ryan was great with my dryer repair. He complete the task in less than 1 hr and was great with responding quickly! Thank you.
They responded very quickly to my call and arrived timely (appreciated the text that they were on the way & when they arrived). They were very nice and explained everything that they found wrong with my dryer and walked me through the process of how they would repair the issues prior to repairing it. Would recommend!
Technician arrived on time and was courteous and professional in their explanation. I felt comfortable with their recommendations. Appreciate the level of service from this small company
Had our washing machine break mid-cycle on a Sunday. Within a few minutes of reaching out to them, the team at Wilson and Myers had contacted me with available times including that very evening, no additional fees for a weekend. The tech that arrived was really friendly and professional and got the job done quickly and below the amount I had prepared myself to pay. Will definitely use again if needed!
