What is the difference between AC and central air?
Air Conditioners Window units tend to cool single rooms and are less powerful than central AC. Central AC can cool an entire house and be designed to regulate the cooled air in different ways. Air conditioners can be used in conjunction with furnaces to maintain heat in winter and cooling in summer.
How does a central air unit work?
How Does Central Air Conditioning Work? A central air conditioner works by using your furnace or air handler fan to draw warm air in through your home's duct work. As the air is blown across the evaporator coil, which generally sits above your furnace, heat is removed from the air, cooling it down.
Is central air just air conditioning?
Many homes in North America rely on split-system air conditioners, often referred to as “central air.” Air conditioning systems include a number of components and do more than just cool the air inside. They also can control humidity, air quality and airflow within your home.
How do I know if my house has central air?
A central air conditioner works with a compressor that is almost always located outside the home. This compressor is typically about three feet or four square, with grilles around it for venting hot air. You can also typically see a large fan inside the top cover of the compressor.

What is Central Air Conditioning?
Central air conditioning refers to a whole-house cooling system that controls the temperature of the air inside, and cycles refrigerated air throughout the home by way of ductwork and ventilation.
All the Components of Your Central Air Unit
Hundreds of pieces and parts go into a typical central air conditioning system. You don’t need to know every single part, but it’s good to know the core components of a central air unit. They include:

What is central air?
Central air can be either a split system or a packaged system. A central air system includes: an outdoor unit that houses a fan, condenser coil, and compressor. an indoor unit (typically either a furnace and evaporator coil, or a fan coil) to circulate the cooled air.
What is split system air conditioner?
Split-system air conditioners are the most common type of central air. These systems include both an indoor and outdoor unit. The indoor unit, typically includes a furnace and evaporator coil or a fan coil (air handler), and a blower fan that circulates air throughout the home.
How does a condenser coil work?
The air passes over the evaporator coil and the cooler air is returned back to the home through supply air ducts. The unwanted heat is released to the outside through the condenser coil.
Do split system air conditioners work on rooftops?
They contain an evaporator coil, blower fan, compressor, and condensing coil in one unit. They work well when there isn’t enough space in an attic or closet for the indoor unit of a split-system air conditioner, and are also preferred for rooftop installations.
What is the outside unit of an air conditioner?
Condenser. The condenser is the outside unit of your air conditioning system. It sits outside on the ground and is typically round or square-shaped. The condenser is a very essential part of your system—it’s responsible for releasing the heat that your refrigerant has absorbed into the atmosphere.
What is the compressor in a condenser?
Compressor. The compressor is a large AC component located inside of the condenser and isn’t visible. The compressor helps the condenser by increasing the refrigerant’s pressure enough for the condenser to change the high pressure vapor into a liquid.
How does liquid refrigerant work?
Cooler, liquid refrigerant enters the evaporator from the condenser (via the lineset) and is met with lower pressure. When this happens, the liquid refrigerant turns back into a gas and absorbs heat from the air around it, cooling the inside of your home.
What does the expansion valve do in a compressor?
The expansion valve serves to lessen the pressure of the liquid refrigerant so that it can turn back into a gas inside of the evaporator.

A central air conditioning system uses the forced-air system within your home to deliver cooled air, making use of the vents, plenums, and ducts to provide conditioned air.
Where are the evaporator coils located?
Evaporator coils. The condenser and compressor are both located on the outdoor unit. These, along with the evaporator coils, work in a loop that cycles refrigerant and pulls hot home air in, rejects the heat, then pulls the cooled air back through your vents. In fact, these are the same ones that are part of your forced-air heating!
Is central AC connected to furnace?
The central AC system is independent of your furnace, using an outdoor unit that is not connected to the furnace at all.
