Verify this license yourself at the California Contractors State License Board (CSLB).
Los Angeles homes and businesses deal with long, hot summers and cool winter nights, and both put real strain on heating and cooling equipment. Systems in older buildings tend to wear down faster, and a unit that runs hard for months can lose efficiency long before it fails. GA Ju Cooling Systems serves customers across the Los Angeles area with HVAC work built around these local conditions.

About GA Ju Cooling Systems
The company offers AC Services, Heating Services, Furnace Services, and Heat Pump work, along with Ductwork Services, Thermostat Services, Emergency HVAC response, and Maintenance & Tune-up visits. AC service typically includes checking refrigerant levels, cleaning coils, and testing airflow. Furnace and heating visits focus on burner performance, ignition, and safe venting. Ductwork work looks for leaks and restricted runs that waste energy, while thermostat service covers installation, calibration, and programming. Tune-ups bring these checks together on a regular schedule, which helps catch small problems before they become expensive repairs.

Buying a new AC or heat pump in California
