Chicago Heating and Cooling — Booked This Morning, Fixed By Evening
For over four decades, Chicago Heating and Cooling has been a cornerstone of reliable HVAC service in the Windy City. Founded in 1987 by Roberto Sandoval on the bustling North LaSalle Street, the company has grown from a small family operation into a trusted name for residential and commercial heating and cooling solutions. With each generation taking the reins, the business has remained committed to integrity, craftsmanship, and keeping families comfortable through every season.
Why Chicago Heating and Cooling
A Legacy of Precision: Family-Run Since 1987
Founded in 1987 by Roberto Sandoval on the corner of Michigan Avenue and Madison Street, Chicago Heating and Cooling has been serving the city’s most demanding environments for over three decades. This family-run business is now led by Roberto’s son, Miguel Sandoval, continuing the standard his father set. With more than 39 years combined experience in cleanroom and pharmaceutical HVAC systems, we understand the exacting standards required for maintaining sterile environments—something generic contractors simply cannot match.
Cleanroom & Pharma-Specific HVAC Solutions You Can Trust
Our team specializes in the design, installation, and maintenance of advanced HVAC systems tailored for cleanrooms and pharmaceutical facilities. Whether you're dealing with airflow control, temperature regulation, or pressure differential challenges, we’ve worked on projects involving ISO Class 5 through Class 8 cleanrooms, ensuring compliance with FDA and GMP guidelines. Unlike general contractors who treat every space the same, we know how critical it is to maintain consistent air quality in sensitive environments.

We don’t just offer after-hours support—we provide dedicated emergency service for urgent no-heat/no-cool calls. Our 24/7 line ensures that if your cleanroom or lab facility experiences an HVAC failure, we’re ready to respond immediately. From broken chillers to failed air filtration systems, our certified technicians are trained specifically in industrial and cleanroom applications so you never have to choose between downtime and compromising safety.
