DESIGN
Our design engineers develop turnkey commercial refrigeration, foodservice and HVAC system designs. These designs focus on system layouts and energy enhancements qualifying for utility rebates. Equipped with extensive tools and capabilities, we handle any HVAC, foodservice or refrigeration project, assessing your specific needs to determine the optimal approach.
REMODELS
We undertake hundreds of remodel projects annually. Our scope ranges from expanding existing systems to installing new systems and recycling old models sustainably. We specialize in equipment upgrades, facility expansions, and aesthetic improvements. Leveraging our vast experience, projects are executed on time and within budget.
HVAC & Refrigeration Service and Maintenance
Our certified technicians diagnose and correctly repair refrigeration and HVAC service issues, minimizing downtime and future service calls. Our goal is to deliver high-quality, responsive service 24/7/365.
PREVENTIVE MAINTENANCE
Preventive maintenance proactively identifies and addresses issues before they occur, reducing downtime, repair costs and energy use. Combined with regular tune-ups, it minimizes emergency repairs and unexpected expenses.
REFRIGERATION SERVICE
Our certified technicians accurately diagnose and repair issues, minimizing downtime and the need for future service calls. We are committed to providing quality, responsive service when you need it most.
CASE CLEANING
Regular case cleaning reduces service calls, extends shelf life, ensures health compliance and lowers energy use. Our skilled teams use proper techniques to improve airflow, sanitation, appearance and temperature control. Cleaning is scheduled overnight or during off-hours to minimize disruptions to your business.
COMMISSIONING
New refrigeration systems often have initial, correctable issues. Without commissioning, these lead to poor performance and expensive service calls. Our expert, third-party commissioning assessments and corrective services for grocery store refrigeration systems help prevent these issues, resulting in savings of 6-25% on annual energy usage.
HVAC SERVICE
We partner with a trusted brand to provide diagnostics and repairs for most commercial HVAC systems. Our technicians are trained to handle common repairs, with specialists available for complex equipment. We service all major brands of heating, AC and air handling systems.

With over 60 years of experience, our team provides expert repair services for commercial food service equipment throughout Wisconsin. We serve local restaurants, national chains, cafeterias, convenience stores and grocery stores. As one of the Midwest’s largest parts suppliers, we maintain a comprehensive inventory of thousands of components to ensure your equipment operates smoothly.

Our Energy Optimization team takes cost-effective approaches to enhance the operation, value and usable life of your refrigeration and HVAC equipment, ultimately increasing your bottom line.
EXCLUSIVE “OPTIMAL ROI” ANALYSIS

ENERGY-SAVING EQUIPMENT UPGRADES
Our energy surveys and audits deliver comprehensive, energy-saving recommendations for supermarkets, convenience stores, foodservice and commercial operations. These solutions reduce annual energy costs by up to 25%, including advanced LED lighting (interior/exterior), high-efficiency ECM evaporator fan motors, night shades and anti-sweat heater controls.
ENERGY REBATES
As a closely involved, registered trade ally with Wisconsin’s Focus on Energy Program, our certified energy-efficiency experts have participated in some of the largest energy-rebate projects offered. We excel at maximizing your energy incentive checks.
RECOMMISSIONING
Refrigeration systems naturally drift from design settings, reducing performance. This inefficiency leads to costly repairs and wasted energy. Our recommissioning service corrects unresolved issues, restoring your system to its optimal design parameters and peak performance.
