Air Conditioner Basics
An air conditioner is essentially a heat pump that transfers heat from inside your home to the outside. It works by blowing cool air into your home through a network of ducts.
The most common type of air conditioner is a split system, which consists of an indoor unit and an outdoor unit. The indoor unit is usually installed in a wall or ceiling, while the outdoor unit is typically placed in a yard or on a roof.
Air conditioners use refrigerant to cool the air, and the most common type of refrigerant is R-410A, which is a more environmentally friendly option than older refrigerants like R-22.

Air Conditioner Types
There are several types of air conditioners available, each with its own unique features and benefits.
The most common type is the central air conditioner, which is a whole-house cooling system that uses a condenser fan motor to circulate air and cool the entire home.
Split air conditioners, on the other hand, are window-mounted units that can cool a single room or a small area.
Portable air conditioners are another option, offering flexibility and ease of use, but they often require more maintenance than other types.
The size and capacity of an air conditioner are determined by its BTU rating, which measures the unit's cooling power in British Thermal Units.
In general, a higher BTU rating means the unit can cool a larger space or a larger number of people.
