Honest, certified heating, cooling and refrigeration for homes and businesses across Joliet — done in English and Spanish, by the family that answers your call.
Heavy Duty Heating & Cooling is owned and run by a Joliet family. Ángel works side by side with his mom and dad, so when you call, you reach the people who actually do the work — not a call center, not a rotating crew of strangers.
We built this company on one idea: do the work right, explain it clearly, and charge a fair price. A lot of our customers came to us after another company couldn't solve the problem or overcharged them. We earn the next call by being honest on the first one.
And because we are fully bilingual, we handle everything in English and Spanish — from the first phone call to the final invoice. Nobody has to struggle to explain what's wrong with their heat, AC or cooler.
On the job in Joliet
HVAC changed fast, especially refrigerants. We're certified on the systems being installed right now, including the newer low-GWP refrigerants that became standard across the U.S. in 2025 — while a lot of contractors are still set up only for the old ones.
The highest tier of EPA refrigerant certification — every system type, including commercial walk-in coolers and freezers.
Trained to safely handle the new hydrocarbon and HFO (A2L) low-GWP refrigerants used in modern AC, mini-splits and refrigeration.
HVAC/R preventive-maintenance certified — keeping systems running longer and catching problems before they break down.
A licensed and insured HVAC contractor serving Will, Cook and DuPage Counties — your home and investment are protected.
From a quick repair to a full system replacement — for homeowners, property managers and local businesses.
AC repair & installation, furnace repair & installation for homes and businesses.
Ductless mini-splits for garages, additions, basements and offices where ductwork isn't practical.
Commercial HVAC plus walk-in coolers and freezers — equipment many residential companies won't touch.
When heat, cooling or a cooler can't wait. Call or text and we respond as fast as we can.
