Frontier Heating and Cooling Services LLC

Frontier Heating and Cooling Services LLC operates as a licensed HVAC contractor serving residential and light commercial clients throughout Addison, Illinois, and surrounding DuPage County communities. The company maintains standard operating hours seven days per week, opening at 7 AM and closing at 8 PM daily except Saturday, which accommodates homeowners who cannot schedule service during traditional weekday windows. With a current rating of 3.8 stars derived from four published customer reviews, the business occupies a middle tier among local competitors in the greater Chicago metropolitan area. The name suggests an operation with roots in the Midwest heating and cooling tradition, though founding year and precise license registration numbers are not displayed in public directories reviewed for this profile.

The contractor offers standard residential heating and cooling services including system repairs, maintenance tune-ups, and new equipment installations. Without access to the company website at the time of this review, definitive statements about brand partnerships, factory certifications, or specialized equipment offerings cannot be confirmed. The working hours pattern, spanning twelve hours daily across six of seven days, represents a more accessible scheduling window than many neighboring competitors who restrict Saturday availability or limit weekday coverage to standard business hours.
