How do you service an air conditioner?

Air conditioner servicing includes inspecting and cleaning key components, checking refrigerant levels, testing electrical systems, and ensuring proper airflow. While homeowners can change filters and clear debris around the unit, a licensed technician is needed for full servicing. At Mainstream, our detailed AC tune-up includes coil cleaning, thermostat testing, capacitor checks, and clearing the condensate drain line—everything your system needs to run efficiently and reliably.
