What is the difference of AC and HVAC?

 AC and HVAC are related terms, but they refer to different concepts:

1. **AC (Air Conditioning):**

   - **Definition:** AC stands for air conditioning, and it specifically refers to the process of controlling and adjusting the temperature, humidity, and cleanliness of air within a confined space, typically a room or a building.

   - **Function:** The primary function of an air conditioner is to cool the air. It removes heat from the indoor air and releases it outside, providing a more comfortable and controlled environment.

2. **HVAC (Heating, Ventilation, and Air Conditioning):**

   - **Definition:** HVAC is a broader term that encompasses the entire system responsible for heating, ventilation, and air conditioning. It is a comprehensive system that aims to provide a comfortable and controlled indoor environment by regulating temperature, humidity, and air quality.

**Components:**

1 - **Heating:** The system includes components for heating, such as a furnace or heat pump, to raise the temperature during colder periods.

2 - **Ventilation:** HVAC systems include ventilation systems that exchange indoor and outdoor air, providing fresh air and maintaining air quality.

3 - **Air Conditioning:** As with AC, HVAC systems include components for cooling, which can involve various methods like central air conditioning or split systems.

In summary, AC specifically refers to air conditioning and focuses on cooling indoor air. On the other hand, HVAC is a broader term that encompasses the entire system, including heating, ventilation, and air conditioning, with the goal of maintaining a comfortable and healthy indoor environment.
