Summit summers bring the same heat and humidity as the rest of the Chicago metro, and aging duct systems can significantly reduce AC performance. Common AC problems in Summit homes include warm air from the vents, frozen evaporator coils, refrigerant leaks, failed capacitors, and airflow imbalances caused by leaking or undersized ductwork. D's Air & Heating diagnoses AC problems accurately on the first visit and can identify duct system issues that are causing comfort problems. We service all major AC brands and carry common parts on our trucks for same-day repairs. Call (773) 940-0965 for AC repair in Summit, Illinois.

Heat pumps and ductless mini-split systems are an excellent solution for Summit homeowners looking to add efficient, zoned comfort to specific areas of the home. Mini-splits are particularly useful for room additions, finished basements, and areas of the home that are difficult to condition with the existing duct system. Modern heat pumps can operate efficiently even in Chicago's cold winters, and dual-fuel systems that pair a heat pump with a gas furnace backup provide maximum efficiency across all temperature ranges. D's Air & Heating installs and services all major mini-split brands including Lennox, Daikin, Mitsubishi, and LG. Call (773) 940-0965 for a free estimate on heat pump or mini-split installation in Summit, Illinois.
