An air conditioner has 5 main parts:

  • Refrigerant. Refrigerant (also known as coolant or by its brand name Freon®) is a special fluid that is vital to cooling and freezing technology.
  • Compressor.
  • Condenser Coil.
  • Expansion Valve.
  • Evaporator Coil.

Do HVAC systems pull air from outside?

No, air conditioners do not bring in fresh air from the outside. What actually happens is that your air conditioner uses a fan to draw air into the unit and disperse it through a structure. This results in recycled air. The air that’s sucked in passes through coils before going into a home.

Where is the evaporator coil located?

Inside the home, the evaporator coil, sometimes referred to as the cooling coil, is located on the air intake side of the fan coil or the outlet side of the furnace. Its job is to remove heat from indoor air so the blower fan can return cool, refreshing air to the home.

What are the three main components of an air conditioning system?

Three major components in the air conditioning unit need to be analyzed frequently. The components are the indoor fan motor, compressor and outdoor fan motor. All the equipment has a range of rating, and they have to start with that range.

Where does HVAC pull air from?

The fan from the indoor unit pulls hot air from inside the house through return air ducts. This air passes through filters where dust, lint and other airborne particles are collected. The filtered, warm indoor air then passes over cold evaporator coil.

What causes an evaporator coil to freeze?

One of the most common causes of a frozen evaporator coil is lack of system airflow. If there isn’t enough air blowing over your evaporator coil, the coil won’t have enough heat to absorb. This will cause the condensation on the coil to freeze over. Dirty air filter.
