Why Choose PHD?
Combo heating and cooling systems provide year-round comfort with a single, efficient unit. At PHD Heating & Cooling, we specialize in engineering-level installation of Carrier combo units, completed by a licensed and insured HVAC team trained to deliver precise, clean, and long-lasting workmanship.
As a Carrier Authorized Dealer, we install high-efficiency combo systems designed for stable performance in both summer and winter. Our installation process includes correct equipment sizing, duct evaluation, static pressure balancing, safe electrical integration, refrigerant accuracy, and full performance testing. These steps ensure efficient cooling, reliable heating, and reduced energy costs.
Unlike large companies that often rush installations, our small, detail-focused team takes the time to do every job correctly. Dmytro — a PhD in Technical Sciences — oversees installation standards to guarantee engineering-level precision.
We serve Chicago neighborhoods such as West Loop, West Town, Lincoln Park, Wicker Park, and suburbs including Elmhurst, Wilmette, Northbrook, and more.
