Before diving into diagnostics, it’s essential to have a fundamental understanding of how HVAC systems work. HVAC systems generally consist of the following main components: 24 Hour Emergency Heating Service Fix My Air Conditioner 24 Hour Ac Service Near Me Air Conditioning Service Companies Near Me

• Heating: Furnaces, boilers, heat pumps, and electric heaters generate heat.
• Ventilation: Air handling units (AHUs), fans, and ductwork circulate and distribute air.
• Air Conditioning: Air conditioners, chillers, and heat pumps cool and dehumidify air.

These components work together to regulate temperature, humidity, and air quality within a building. Refrigerant, a specialized fluid, plays a critical role in the air conditioning process, absorbing and releasing heat to cool the air.
