Understanding Your AC System 24 Hour Ac Company Hvac Fix Near Me Commercial Hvac Service Near Me Weekend Ac Repair Ac Fixing

Before we dive into troubleshooting, it’s essential to have a basic understanding of how an air conditioning system works. AC units operate on the principle of heat transfer, using a refrigerant to absorb heat from the air inside your home or building and release it outside. The primary components involved include: Emergency Heating Repair Near Me Ac Experts Near Me 24 Hour Hvac Service Near Me Weekend Air Conditioner Repair Heating Repair In My Area

• Compressor: The heart of the system, responsible for compressing the refrigerant, increasing its pressure and temperature.
• Condenser: Located outside, it releases heat from the refrigerant into the outside air.
• Evaporator: Located inside, it absorbs heat from the air, cooling it.
• Refrigerant: A special fluid that absorbs and releases heat.
• Expansion Valve (or Metering Device): Regulates the flow of refrigerant.
• Ductwork: Carries cooled air throughout your home or building.
• Thermostat: Controls the AC system, setting the desired temperature.
