WISCONSIN COMMERCIAL COLD SIDE SERVICE & REPAIR
Commercial Refrigeration Repair
Refrigeration in southeastern Wisconsin has to survive two seasons that work against it: rooftop condensers running in subzero cold and walk ins fighting humid summer air. A-1 Services Group repairs walk ins, reach ins, ice machines, display cases and the condensing units that serve them, across southeastern Wisconsin, and we handle the electrical side of refrigeration failures too.

How Commercial Refrigeration Repair Works
Here’s how A-1 handles a refrigeration call, from the first phone call to the box holding temperature again.
Call or Request Online
Call 414-404-9739 or send a request online with the unit type, the current reading on its thermometer and when you first noticed it. Product at risk? Say so right away; anything holding food above 41°F is dispatched as an emergency.
Rapid Dispatch
A technician based in the Milwaukee area is assigned to your call. In winter, rooftop condensing unit calls often mean snow covered roofs, so let us know how the roof is reached and whether the path to the unit is clear; it gets your repair started sooner.
Diagnose & Repair
The technician tracks the cause to its source, from fan motors, start components and refrigerant leaks to winter controls on a rooftop unit or an electrical fault feeding the system. Any refrigerant work is handled by technicians holding EPA Section 608 certification, using approved recovery equipment.
Test, Document, & Follow Up
Before sign off, the technician watches the box pull down to temperature and stay there through a full cycle, then documents the work. A-1 guarantees parts and labor for 90 days; a repeat of the same failure in that window brings us back at no charge.
THE A-1 DIFFERENCE
Why Choose A-1 Services Group For Commercial Refrigeration?
A refrigeration failure puts food safety, inventory and your next inspection at stake all at once. Here’s why Milwaukee area businesses call A-1 for the cold side.
Highly Skilled Technicians
A-1 refrigeration technicians train through Tech24 University, carry the federally required EPA 608 credential for handling refrigerant, and bring the HVAC background that refrigeration and rooftop systems share.
We Stock the Most Commonly Used Parts
Trucks are stocked with the cold side parts that wear out most, including condenser and evaporator fan motors, start relays, capacitors, thermostats, defrost timers and heaters, door gaskets and common refrigerants, so more boxes are back in range on the first visit.
90-Day Guarantee
A-1 guarantees parts and labor on every A-1 refrigeration repair for 90 days. If the same failure comes back in that time, the return visit costs you nothing.
Planned Maintenance Programs
A fall visit checks winter controls, crankcase heaters and door heaters before the first cold snap; a spring visit cleans condenser coils and checks charge before summer humidity arrives. Both include gasket, defrost and temperature checks.

Commercial Refrigeration Repair FAQ
Answers to the questions we hear most from restaurant, c-store, and grocery operators. Don’t see yours? Give us a call.
A-1 Services Group, based in Oak Creek, provides commercial refrigeration repair across southeastern Wisconsin, including Milwaukee, Racine, Kenosha and Waukesha. That includes walk in cooler repair, reach ins, ice machines, display cases and rooftop condensing units.
We work with restaurants, taverns, supper clubs, grocery stores, schools and facilities, with 24/7 service for emergencies.
A-1 services all major commercial refrigeration brands, self contained and remote, from walk in systems and reach ins to display cases and ice machines. Share the make and model when you call so the technician can bring the right parts.
Older systems are welcome too, including walk ins and remote condensing units that have been on the roof for many years. Your technician will tell you when a repair still makes sense.
At or below 41°F for coolers; Wisconsin’s food code follows the FDA Food Code for cold holding, and many kitchens set coolers a few degrees colder for a margin. Freezers are generally kept at 0°F or colder.
Log readings at least twice a day. If a cooler climbs past the limit and hasn’t come back down an hour after the door was closed, check product temperatures and call for service.
Fix it when the box is in good shape and the failure is a fan, relay, control or leak. Replace it when an aging compressor gives out, leaks keep coming back, or the system uses R-22, a refrigerant no longer made in the United States that costs more to recharge every year.
If you replace, Wisconsin businesses may qualify for Focus on Energy incentives on qualifying efficient refrigeration. Your A-1 technician can price the repair and the replacement side by side.
Yes. A-1 provides electrical service alongside refrigeration repair, so a compressor that won’t start because of low voltage, a failing disconnect or an overloaded circuit doesn’t need a second contractor.
That matters when a new walk in or ice machine is added, when a unit keeps tripping a breaker, or when it’s unclear whether the fault is in the equipment or the building’s power.
