• Evaporator Coils: Located inside the room, these coils absorb heat from the air, cooling it down.
• Fan Motors: Two fan motors circulate air: one for the condenser coils (outside) and one for the evaporator coils (inside).
• Thermostat: Controls the temperature setting and turns the unit on and off.
• Control Board: The "brain" of the AC unit, controlling the various components.
• Filters: Remove dust and debris from the air, protecting the coils and improving air quality.
