Why Choose PHD?
Routine AC maintenance is essential for keeping your system efficient, reliable, and ready for the hottest months of the year. PHD Heating & Cooling provides comprehensive, precision-driven AC maintenance, performed by licensed and insured HVAC technicians who follow high technical standards.
While our installations focus on Carrier systems, we maintain all AC brands, including:
Carrier, Bryant, Trane, Lennox, Goodman, Amana, Rheem, Ruud, York, American Standard, Heil, Comfortmaker, and more.
Maintenance includes condenser checking, refrigerant verification, checking level of refrigerant, temperature checking, electrical inspection, airflow checking, drain line checking, thermostat checking, and system optimization. These steps significantly improve cooling performance, reduce energy bills, and extend equipment life.
As a smaller company, we take the time to perform maintenance thoroughly — not the 5-minute “quick check” many large companies do.
We serve Chicago (West Loop, Lincoln Park, Lakeview, West Town, Wicker Park) and suburbs (Wilmette, Elmhurst, Palatine, Northbrook).
