HVAC Services Pasadena CA | Call HKS Heating and Cooling Air

We are experienced with all major system types common in our area. This includes traditional furnaces and central air conditioners, energy-efficient heat pumps, and versatile mini-split ductless systems. Whether you're updating an older home, working on a new construction, or adding an ADU, we can recommend and install the right system for your space and budget.

In Pasadena's climate, two common culprits are duct leakage, which reduces airflow and wastes cooled air, and dirty coils or low refrigerant levels. Our service begins with a thorough inspection of your entire system. We'll check for leaks in your ductwork, assess the condition of the evaporator and condenser coils, and verify refrigerant charge to diagnose the root cause and restore your cooling efficiency.

Consistent maintenance is key to preventing major breakdowns, especially before our hot summers. Our maintenance service includes cleaning critical components, checking electrical connections, lubricating moving parts, and ensuring proper refrigerant levels. This proactive care helps your system run more efficiently, extends its lifespan, and can improve your indoor air quality, saving you money on energy and repair costs.
