Role & bio
Contractor contributor
David Kim is a Queens-based contractor contributor to AC Repair AC. He is a licensed HVAC contractor and EPA Section 608 certified.

David writes and reviews service-oriented guidance with New York City homes in mind, from window units and PTACs to ductless systems. He helps our editors separate routine maintenance questions from issues that call for a qualified professional. His perspective is used to make technical articles more precise without turning them into a substitute for an on-site assessment.
He also flags when building conditions, electrical requirements, refrigerant handling, or equipment access can make a seemingly simple job more involved than a general guide suggests.
