This is the piece of your air conditioning system that most people never see.

Attic ac unit diagram.

If you have a horizontal furnace in an attic the evaporator coil will sit on one end of the furnace instead of on top. When the thermostat signals the air conditioning system to lower air temperature a whole sequence of events begins. Notice the drain pan under the air handling unit to catch condensation if the primary pan were to overflow. 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.

This is the secondary condensation pan which is installed under the air handler to save a ceiling. So why put an hvac system up in the attic at all. First the air handling unit kicks on drawing room air in from various parts of the house through return air ducts. This is a horizontal flow air handler installed in the attic.

Comparing this configuration to a solar water heater they make the case that putting air conditioning ducts in a hot attic is an effective way to heat up the conditioned air as it travels from the air handler to the conditioned space inside the home. Refrigerant enters the condenser as a vapor but turns. The condenser is the outside unit of your air conditioning system. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.

It sits outside on the ground and is typically round or square shaped. Attic hvac systems save space. My unit is over 16 years old which is ancient in florida.
