Before diving into troubleshooting, it’s crucial to have a basic understanding of how an HVAC system works. HVAC stands for Heating, Ventilation, and Air Conditioning. These systems typically consist of the following key components: Emergency Heating Repair Near Me Phoenix Air Conditioning Service Air Conditioning Repair Companies Near Me Air Conditioning Heating Repair Home Heating Repair Service Near Me Hvac Emergency Repair Near Me

• Furnace or Heating Unit: This component generates heat, usually through the combustion of natural gas, propane, or electricity. It also houses the blower fan, which circulates heated air throughout the building.
• Air Conditioner (AC) or Cooling Unit: The AC unit removes heat from the air, cooling it down. It typically includes a compressor, condenser coil, evaporator coil, and refrigerant.
• Evaporator Coil: It is located in the indoor unit and absorbs heat from the air, cooling it.
• Condenser Coil: This is located in the outdoor unit and releases the heat absorbed by the refrigerant.
• Refrigerant: A fluid that absorbs and releases heat, circulating throughout the system.
• Ductwork: A network of pipes or channels that distribute conditioned air throughout the building.
• Thermostat: A control device that monitors the temperature and regulates the operation of the heating and cooling systems.
• Air Filter: This component removes dust, pollen, and other airborne particles from the air, improving air quality.
