We serve Joliet residents and businesses with the same quality and care we'd give our own family. Licensed, certified, and bilingual — English and Spanish.

Joliet is the county seat of Will County and the third-largest city in Illinois — and Heavy Duty Heating & Cooling is proud to call it home. We've built our reputation here one honest job at a time, serving neighborhoods from Cathedral Area and Logan Manor to Rock Run and River Road, and every ZIP code in between: 60431, 60432, 60433, 60434, 60435, and 60436.
What sets us apart in Joliet? Three things: bilingual service (English and Spanish — no language barrier), honest pricing (we quote before we start, always), and commercial expertise including walk-in coolers and freezers that most Joliet HVAC companies won't service. Whether you need AC repair in the summer heat, furnace service in the dead of winter, or a commercial refrigeration emergency at 2 AM — we respond.
Joliet has a rich mix of housing stock — from 1920s bungalows near the historic downtown to brand-new builds in Joliet's growing north and west sides. We're experienced with all of it: vintage systems in older homes, high-efficiency equipment in new construction, and everything in between.
