Choose your city
In Illinois, the transition from warm to cold weather means your HVAC system will work harder. Ductless mini-splits offer targeted cooling and heating, ideal for homes that lack existing ductwork, common in older Chicago neighborhoods. Installation involves mounting an outdoor compressor unit and one or more indoor air-handling units. We secure the outdoor unit, typically on a pad or bracket, and then run refrigerant lines and electrical wiring through a small hole in your exterior wall to the indoor units. Proper sealing of this penetration is crucial to prevent air and water intrusion.
