Recent HVAC Installations & Repairs by Our Team
Real work from our own jobs — air conditioning, heating, ductless and commercial HVAC.
Ductless mini-splits, AC and furnace service for Naperville homes and businesses. Licensed, insured, bilingual EN/ES. Free estimates on new installations.
When your air conditioner quits on the hottest day of summer or your furnace won't start on a cold Illinois night, Heavy Duty Heating & Cooling responds fast to Naperville. We're based nearby in Joliet and treat every Naperville home and business with the same care we'd give our own family. Licensed, certified, and bilingual — English and Spanish.
We offer free estimates on new installations, fair pricing with no surprise charges, and 24/7 emergency availability across Naperville and the surrounding DuPage & Will Counties communities.
Naperville blends established 1980s and 1990s neighborhoods with newer construction, and many of those homes have spaces that central air never reaches well — sunrooms, additions, bonus rooms over the garage, and finished basements. That's exactly where a ductless mini-split shines: independent, energy-efficient comfort without tearing into existing ductwork.
We also handle the bigger picture: high-efficiency AC and furnace replacements for Naperville homes whose original systems are aging out, plus repairs when something quits at the worst possible time. We size and install correctly, quote up front, and explain your options in plain language.
Serving Naperville across DuPage and Will Counties (60540, 60563, 60564, 60565), with same-day and 24/7 emergency response in English or Spanish.
