Commercial HVAC & Refrigeration Services
While Keystone Heating & AC is a household name for residential comfort, our legacy in Southeastern Wisconsin was built on the back of heavy-duty commercial mechanical services. Since 1918, we have provided the specialized engineering, installation, and rapid-response repair that Racine and Kenosha businesses need to stay operational. As a Pro Partner with Rheem, we install high-performance commercial systems designed to withstand the rigorous demands of Wisconsin’s climate. Whether you are managing a single storefront or a massive industrial complex, the Keystone team brings over a century of expertise to your facility!
Custom HVAC Solutions for Every Sector
Commercial environments require more than just "bigger” equipment; they require precise load calculations and specialized zoning. We are proud to provide tailored HVAC and refrigeration solutions for a wide range of industries across Racine and Kenosha counties:
Industrial & Manufacturing Facilities
We understand the unique requirements of factory environments, where temperature control is often tied to equipment performance and worker safety.
Education & Healthcare
From local schools and colleges to clinics and healthcare offices, we provide air filtration and ventilation systems that prioritize the health and comfort of students and patients.
Hospitality & Restaurants
In addition to heating and cooling, we offer specialized refrigeration services for taverns and restaurants. From walk-in coolers to draft systems, we ensure your inventory stays at the perfect temperature.
Multi-Family Housing
We partner with managers of apartment and condo complexes to provide scalable HVAC solutions that are energy-efficient and easy to maintain across multiple units.
Retail & Office Spaces
For retail shops and office buildings, we focus on high-efficiency Rheem rooftop units (RTUs) that provide quiet, consistent comfort for customers and employees alike.
Historical Buildings
Racine and Kenosha are home to beautiful historic architecture. These buildings often rely on complex boiler systems rather than modern ductwork. Our deep history allows us to service and preserve these legacy systems while integrating modern efficiency.
Commercial Heating & Cooling Installation
A commercial HVAC system is one of the largest investments a business owner will make. At Keystone Heating & AC, we specialize in the installation of Rheem commercial systems, known for their industry-leading durability and energy ratings. Our team handles everything from the initial design-build phase to the final crane-set of rooftop units. We don’t just install equipment; we ensure the ductwork, thermostat controls, and ventilation are all optimized to lower your monthly overhead.
Rapid Commercial Repair & 24/7 Emergency Service
In the business world, a broken furnace or a failed walk-in cooler isn’t just an inconvenience; it’s a loss of revenue. Our commercial technicians are trained to troubleshoot large-scale systems quickly. We offer priority service to our commercial clients in Racine and Kenosha to ensure your doors stay open. Whether it’s a failed compressor in a restaurant’s refrigeration unit or a broken blower motor in an industrial air handler, we arrive with the tools and parts needed to fix the issue on the first visit!
Proactive Commercial Maintenance Plans
The best way to avoid a costly emergency repair is through a Keystone Commercial Maintenance Agreement. Commercial systems run harder and longer than residential ones. Without regular coil cleaning, filter changes, and electrical inspections, even a high-end Rheem system will lose efficiency and eventually fail. We provide scheduled maintenance for schools, retail centers, and industrial plants, providing you with a documented service history that protects your equipment's warranty and extends its lifespan.
Expert Commercial Refrigeration
Unique to the Keystone team is our expertise in commercial refrigeration. For our clients in the hospitality and restaurant sectors, we provide installation and repair for walk-in freezers, reach-in coolers, and specialized cooling systems. We understand that in the tavern and restaurant industry, refrigeration is the heart of the business. Our technicians ensure your systems meet all health code requirements while operating at peak electrical efficiency.
Why Racine Businesses Trust Keystone
Choosing a commercial partner means choosing someone who knows the local landscape. We are familiar with the specific building codes in Racine, Kenosha, and the surrounding municipalities. When you work with the Keystone team, you are working with a local partner who is committed to the economic success of our community.
