Our maintenance service is designed to prevent common problems and extend your system's life. We perform a comprehensive check, which includes cleaning critical components like evaporator coils—a frequent issue in our area—inspecting the blower motor, checking refrigerant levels, and ensuring all electrical connections are secure. This proactive approach helps catch small issues before they lead to costly repairs or system failures, especially important during Los Angeles's hot summers.

If your unit is over 10-15 years old, requires frequent repairs, or is causing high energy bills, a replacement might be more cost-effective.

Yes, dirty evaporator coils are a very common reason for reduced cooling in Los Angeles homes. Dust and debris buildup insulates the coil, preventing it from absorbing heat properly. Our repair service includes a thorough inspection and professional cleaning of the coil system. We also check for related issues, like airflow restrictions or refrigerant leaks, to restore your system's efficiency and cooling power completely.
