Citywide Supply and Service

About Citywide Supply and Service

At Citywide Supply and Service, we’ve built our reputation as one of Chicago’s most trusted HVAC and refrigeration companies. For years, businesses and homeowners across the city have turned to us for heating, cooling, and commercial refrigeration services that combine expert craftsmanship, fast response times, and a commitment to doing the job right the first time.

Our Story

Citywide started with a simple goal: to provide reliable heating and cooling service to our neighbors right here in Chicago. What began as a small crew helping local homeowners quickly grew into a full-service company trusted by restaurants, businesses, and families across the city.

We’ve stayed true to our roots since 1966 — serving only Chicago. That means we know the neighborhoods, the buildings, and the people who make this city great. From a condo in the South Loop, to a family home in Portage Park, to a restaurant in the West Loop, our team has been there, keeping Chicago running no matter the season.

Chicago’s Heating, Cooling & 
Refrigeration Experts

Our focus is simple: provide reliable, high-quality service to the communities we know best. Unlike companies that stretch their crews across multiple suburbs, Citywide only serves Chicago. That means faster response times, technicians who understand local building needs, and a team that’s always nearby when you need us most.

From walk-in cooler repair in West Loop to furnace installation in Lincoln Park, our crews bring the same dedication to every project — large or small.

Our Services

Citywide Supply & Service specializes in:

  • Heating – furnace repair, boiler service, and new heating system installations.
  • Cooling – air conditioning repair, maintenance, and installation.
  • Commercial Refrigeration – walk-in coolers, reach-in coolers, freezers, and ice machine service.
  • 24/7 Emergency Response – around-the-clock support for HVAC and refrigeration emergencies.
  • Preventive Maintenance – scheduled service programs to reduce breakdowns and extend equipment life.

Our Commitment

We know that heating, cooling, and refrigeration failures don’t just cause discomfort — they disrupt businesses, families, and communities. That’s why we’ve built Citywide Supply & Service on a simple promise: be there when our customers need us most.
