Before diving into troubleshooting, it’s helpful to understand how an air conditioning system works. The core components involved in air circulation include: Emergency Heating Repair Near Me Emergency Air Conditioner Repair Near Me Same Day Hvac Repair Heating Cooling Repair

• Compressor: The heart of the system, it compresses refrigerant, increasing its pressure and temperature.
• Condenser: Located outside the home, it releases heat from the refrigerant, transforming it from a hot gas to a liquid.
• Evaporator: Located inside the home, it absorbs heat from the air, cooling it down.
• Blower Motor: A fan that circulates air over the evaporator coil, distributing cool air throughout the home.
• Ductwork: The network of ducts that carries the cooled air from the air handler to the vents in your rooms.
• Air Filters: These filters trap dust, dirt, and other particles, preventing them from entering the system and clogging components.

When the AC is operating correctly, the blower motor pulls warm air from your home, passes it over the cold evaporator coil, and then distributes the cooled air through the ductwork and out the vents. 24 Hour Emergency Heating Service Ac Emergency Repair Near Me Weekend Ac Repair Emergency Hvac Service Near Me
