We Deliver Trusted HVAC Expertise With Precision, Care, and Integrity
Our Story
At PHD Heating & Cooling, we combine technical expertise, academic precision, and true craftsmanship to deliver HVAC solutions you can rely on for years.
My name is Dmytro, founder of PHD Heating & Cooling and your “Professor of Heating & Cooling.” I hold a PhD in Technical Sciences from one of Ukraine’s top universities, where I also worked as a lecturer and professor before moving to the United States.
The same discipline, engineering logic, and attention to detail I taught in the classroom now define how our company operates.
A Professional, Detail-Driven Team
Today, PHD Heating & Cooling is a small but highly skilled team of 4–5 technicians, each trained to follow the same meticulous installation and service standards.
We are a family-oriented company — not a large corporation — which gives us the ability to deliver:
-
precise, detail-oriented installations
-
honest diagnostics and transparent recommendations
-
fast communication and reliable scheduling
-
consistent quality control on every project
I personally oversee every furnace, AC system, heat pump, boiler, or rooftop unit we install to ensure it meets the highest engineering and industry standards.
With a strong technical background, we approach every HVAC system with proper calculation, correct sizing, and attention to airflow and efficiency. Our clients appreciate that we take the time to do things right — no shortcuts, no rushed installs, just clean, high-quality workmanship built to last.
