PhD Heating & Cooling

PhD Heating & Cooling has earned a 4.9-star rating across 68 verified reviews in Chicago, establishing itself as one of the most highly recommended HVAC contractors in the metro area. Founded by Dmytro, who holds a PhD in Technical Sciences and brings engineering-level methodology to every project, the company operates as a licensed and insured team committed to what they call their Premium Installation Standard. Serving Chicago residents and surrounding suburbs, the company handles air conditioning, heating systems, boilers, tankless water heaters, and mini-split installations with the same precision approach Dmytro once applied to academic research.

The distinguishing factor at PhD Heating & Cooling is their engineering-driven approach to installation work. Rather than rushing through standard setups, their technicians follow a detailed process that ensures proper system sizing, safe configuration, and long-term reliability. They install trusted equipment brands including Carrier systems, and unlike contractors who decline challenging jobs, this team has tackled complex boiler repairs that other companies refused to attempt. Each project receives the same methodical attention, whether it is a straightforward furnace replacement or a multi-component boiler system requiring custom solutions.
