Commercial Heating & Cooling in Milwaukee
Keep your customers comfortable and your equipment running. Dependable commercial HVAC service, repair, and installation for Milwaukee-area businesses.
Downtime costs money. Whether you run a storefront on National Avenue, an office in the Third Ward, or a multi-unit building in Wauwatosa, E & R Heating and Cooling keeps your heating and cooling systems running so you can focus on your business. We've served Milwaukee-area commercial clients since 2003 with responsive service and straightforward pricing.
Commercial Services We Provide
Sized Right the First Time
Commercial spaces have wildly different loads than homes — occupancy, equipment heat, ventilation code requirements, and roof exposure all matter. We size and install systems based on real load calculations, not guesswork, so you get even comfort and predictable operating costs. And with a preventive maintenance plan, small issues get caught at seasonal checkups instead of becoming mid-January emergencies.
A Local Partner, Not a National Call Center
When you call E & R, you talk to the same local team every time. We keep records on your equipment, know your building's history, and answer 24/7 when something breaks. That's how we've kept Milwaukee businesses comfortable for over two decades.
