Many people get confused about HVAC and central air. They both deal with air. But they are not the same. Let’s explore the differences.
What is HVAC?
HVAC stands for Heating, Ventilation, and Air Conditioning. It covers three functions. These are heating, ventilation, and cooling. HVAC systems are used in homes and buildings.
Functions Of Hvac
- Heating: Keeps the house warm in winter.
- Ventilation: Brings fresh air inside and removes bad air.
- Air Conditioning: Cools the house in summer.
Types Of Hvac Systems
There are different types of HVAC systems. Here are some common ones:
- Split Systems: These have two main units. One unit is inside. The other is outside.
- Packaged Systems: All parts are in one unit. This unit is placed outside the building.
- Ductless Systems: These do not use ducts. They have small units inside each room.
What is Central Air?
Central air is a system that cools the whole house. It uses a network of ducts. Cool air moves through these ducts to all rooms. Central air is part of the HVAC system.
How Central Air Works
Central air has two main parts:
- Outdoor Unit: This unit has a compressor and condenser.
- Indoor Unit: This unit has an evaporator coil. It is usually near the furnace.
Cool air is made in the outdoor unit. This air moves to the indoor unit. Then, it is pushed through the ducts. Each room gets cool air.
Benefits Of Central Air
- Even Cooling: All rooms get the same cool air.
- Convenient: One system for the whole house.
- Quiet: The loud parts are outside.
