Commercial HVAC in Chicago — What Building Owners Should Know
Commercial vs. Residential HVAC
Commercial HVAC systems are designed for larger spaces, higher occupancy loads, and continuous operation. Rooftop packaged units (RTUs) are the most common commercial heating and cooling solution in Chicago — they combine heating, cooling, and ventilation in a single cabinet mounted on the roof. Commercial systems require more complex controls, larger electrical service, and more rigorous maintenance than residential equipment.
Rooftop Unit Selection and Sizing
Commercial RTUs are sized in tons of cooling capacity, from 3 tons for small retail spaces to 50+ tons for large commercial buildings. Proper sizing requires calculating cooling load (heat gain through walls, roof, windows, occupancy, and equipment) and heating load. Oversized RTUs short-cycle, causing temperature swings and premature compressor wear. D's Air performs commercial load calculations on every project.
Permits and Code Compliance
Commercial HVAC work in Chicago requires mechanical permits from the City of Chicago Department of Buildings. Work must comply with the Chicago Building Code, ASHRAE 90.1 energy standards, and ASHRAE 62.1 ventilation requirements. D's Air handles all permit applications and inspections for commercial projects.
Preventive Maintenance Contracts
Commercial HVAC equipment operates year-round under heavy loads. Preventive maintenance — quarterly or semi-annual inspections, filter changes, coil cleaning, belt and bearing checks, refrigerant verification — extends equipment life and prevents costly emergency failures. D's Air offers commercial maintenance contracts tailored to your building's equipment and schedule.
