Understanding Your Air Conditioning System
Types of Air Conditioning Systems
Before diving into repair strategies, it’s important to know the type of air conditioning system you have. The most common types include:
- Central Air Conditioning: This system cools your entire home using a network of ducts.

Each type has its specific issues and repair needs, so identifying your system is the first step.
Key Components of Air Conditioning Systems
Familiarizing yourself with the main components can help you understand potential issues:
- Compressor: The heart of the system, compressing refrigerant and facilitating heat exchange.
- Evaporator Coils: Absorb heat from the air, cooling it before circulating it back into your home.
