Why Choose PHD?
Rooftop units are the heart of cooling for many commercial buildings, multi-unit properties, and large spaces. Their performance depends entirely on the quality of installation. At PHD Heating & Cooling, we provide premium installation and replacement of Carrier rooftop cooling units, performed by a licensed and insured HVAC team trained to deliver engineering-level accuracy and clean, organized workmanship.
As a Carrier Authorized Dealer, we install high-efficiency RTUs engineered for long-term reliability, powerful cooling capacity, and reduced operating costs. Every installation includes correct equipment sizing, curb preparation or modification, precise duct alignment, safe electrical integration, refrigerant accuracy, airflow balancing, and full operational testing.
One of the biggest advantages of choosing us over large HVAC corporations is our meticulous, hands-on approach. We are a small team — 5–6 highly trained technicians — and every installation is done slowly, carefully, and with complete attention to detail. No rushed jobs. No cutting corners. Everything is measured, tested, verified.
Dmytro, the company owner, holds a PhD in Technical Sciences and personally oversees installation standards to ensure flawless execution on each project.
We serve Chicago commercial districts such as West Loop, River North, Fulton Market, Wicker Park, and suburbs including Elmhurst, Northbrook, Wilmette, Glenview, and Elk Grove Village.
