While many modern homes have central air conditioning units, some homes still use fans or window-mounted air conditioners. If you are thinking about switching to a central unit, or recently moved to a home that has one, you may be wondering how a centralized system works.

Understanding the basics of how your air conditioner functions will help you recognize when there is a problem. Scheduling regular maintenance for your system will also help keep your home comfortable, even during extreme weather conditions. Gold Star offers maintenance plans and is the most trusted air conditioning company in Newark.

How Does Central Air Conditioning Work?

Window air conditioning units can only cool a single room, which makes it difficult to keep your home at a comfortable, even temperature. With a central air conditioning unit, your home is fitted with a series of ductwork and supply registers in each room. Air is drawn into the system, cooled and dehumidified, then redistributed into your home through the ventilation system, creating an evenly cool environment.

A central air conditioning system has four main components:

  1. Condenser – This unit, located outside your home, takes high-pressure gas from the compressor and converts it into liquid.
  2. Compressor – This component is located inside the condenser and controls the pressure in your A/C system. It does this by compressing low pressure gas from the evaporator.
  3. Evaporator – This unit is part of the air-handler located near your furnace. It removes heat from your indoor living space and sends it outside to the condenser.
  4. Expansion Valve – Generally located near the evaporator, this valve controls the amount of refrigerant allowed into the evaporator coil. The refrigerant is carried through copper tubing that connects the components, thus creating a closed-loop system.

Choosing the Right System

We tend to think that bigger is better, but that isn’t the case when it comes to central A/C units. A unit that is too large for your home will be inefficient and rack up high energy bills.

You also need to consider the air flow capacity of your ductwork. This is the amount of air your ductwork can move in a minute. Insufficient ductwork will keep your system from functioning properly.
