DuAll Heating & Cooling

DuAll Heating & Cooling has built its reputation over 14 years serving the southwestern suburban corridor of Chicago, including Bolingbrook, Naperville, Plainfield, and Romeoville. With a 4.7-star average drawn from 122 customer reviews, this locally-rooted contractor employs NATE-certified technicians who handle everything from annual furnace tune-ups to complex AC compressor replacements. Homeowners in the area consistently praise the team's punctuality and clear communication, distinguishing DuAll from larger outfits where service requests often vanish into voicemails.

What separates DuAll from neighboring competitors is their investment in indoor air quality technology and manufacturer partnerships. Their lineup includes UV germicidal lights, energy recovery ventilators, and whole-home dehumidifiers, equipment that addresses Chicago's humid summer air and winter indoor stagnation without relying solely on basic ductwork. As an Angie's Listsuper service award recipient and Nicor Gas authorized partner, they also maintain access to utility rebate programs that offset upgrade costs for homeowners pursuing high-efficiency equipment. Every installation carries the DuAll guarantee, promising follow-through until the system operates to the homeowner's satisfaction.

Customer reviews tell the most compelling stories. When Lor's air conditioning failed the night before a record-breaking heat wave, technician Francisco arrived within an hour, diagnosed a faulty capacitor, and had the system running before midnight. Chris Kelstrom's review highlights Kat, who revived a 55-year-old furnace using creative troubleshooting that other contractors deemed unsalvageable. Paula Kenealy's first interaction with DuAll produced an appointment within days, a stark contrast to the two-month silence she endured from her previous HVAC company. These named technicians explain why reviewers consistently mention specific team members by name.
