• Working in Confined Spaces: If working in tight spaces like crawl spaces for ductwork, ensure proper ventilation and be aware of potential heat stress risks.

Main Components:

• Evaporator Coil: Located indoors, this component is made of metal fins with refrigerant flowing through them. Warm indoor air is drawn across the coil, absorbing heat from the air and causing it to cool. Moisture from the air condenses on the cold coil, dripping into a collection pan and exiting the unit as condensate.
• Compressor: The heart of the AC system, the compressor is essentially a powerful pump. It takes low-pressure, cool refrigerant vapor from the evaporator and compresses it, raising the pressure and temperature.
• Condenser Coil: Situated outdoors, the condenser coil consists of metal fins with a fan blowing air through them. The hot, high-pressure refrigerant from the compressor enters the condenser coil. Here, the heat absorbed indoors is released to the outside air, causing the refrigerant to cool down and condense back into a liquid state.
• Expansion Valve: This valve regulates the flow of refrigerant between the condenser and evaporator. As the high-pressure liquid refrigerant passes through the expansion valve, its pressure drops significantly. This pressure drop allows the refrigerant to absorb heat efficiently in the evaporator.

Additional Components:

• Blower Fan: Located indoors, the blower fan pulls air from the living space and pushes it across the evaporator coil to be cooled.
• Air Filter: The air filter removes dust, dirt, and allergens from the air before it passes over the evaporator coil. A clean air filter is essential for maintaining good airflow and efficiency.
• Thermostat: This control unit acts as the brain of the AC system. It senses the room temperature and sends signals to turn the compressor on or off to maintain the desired temperature setting.
• Refrigerant Lines: Insulated copper pipes connect the indoor and outdoor units, carrying the refrigerant throughout the system.
• Drain Line: The drain line carries away the condensate collected from the evaporator coil, typically draining outdoors or into a plumbing system.
