Basic Types of Home Conditioning Systems

There are many types of air conditioners available, each with its own unique features. This article will explain the basics of AC systems and how they can be maintained.

What is the Air Conditioning Process?

Air conditioners use fans to circulate interior air across a cold surface. This is usually made of grids or “coils”, which are typically comprised of copper or aluminum tubing. The coils cool the air and then drain away the moisture.

The refrigerant is pumped through insulation lines to the outside condenser. Low boiling points refer to liquids that have a low temperature at which they turn from liquid to gas. The refrigerant is cooled by the phase change from liquid into gas. Air conditioners cool the refrigerant at the coils by cooling them and taking heat out of the air.

After it has left the coils, the refrigerant is moved to the condenser. There, the compressor pressure changes the refrigerant from a gas to a liquid.

The refrigerant is forced to give up heat gained from the outside air during the second phase. The refrigerant is then returned to the coil after passing through the condenser. The refrigerant flow in heat pumps is reversed, so they provide winter heat the same way that air conditioners do in summer.

Basic Air Conditioning Systems

There are many types of air conditioners available, depending on your specific needs.

Central Air

Central air conditioning is a standard feature in most new homes. Cool air is carried by the same ducts that heat the house in winter. You might find the cooling coils near the air handler, which are large fans that move air through the ductwork.

A “Manual J” calculation should be done by your contractor if you are having a new system installed, or an old condenser removed. Manual-J calculations evaluate the size and insulation of your house as well as solar heat gain through the windows and air leakage. This is the only way to ensure that your condenser has the right size. A condenser that is too small will not cool properly, while one that is too large won’t dehumidify as well.


A mini-split can be described as a small central air system. Many can also be used as heat pumps. A ductless minisplit can have one or more wall-mounted fans that circulate the air depending on how hot the house is. Mini-split ductless mini-split systems use small sections of duct to circulate air between rooms.

Mini-splits are a popular choice for retrofitting air conditioning in older homes and as the primary heat and cooling source in new well-insulated houses due to their high efficiency. To properly size a minisplit, as with central air, make sure that your contractor performs a Manual J calculation.

PTAC Systems

Anyone who has ever stayed in a motel for a night will be familiar with packaged terminal air conditioning systems. PTACs can be installed in any opening in walls and function as heat pumps. As a moderately-priced way to condition smaller homes, PTACs are very popular.

Window AC Units

A window conditioner can be held in place by the upper frame of a double-hung windows. It’s also very affordable. You will want to use them in heating climates every winter as they can leak enormous amounts of air.

Through-the-wall air conditioners are similar to window units. These units are installed inside a wall-mounted sleeve and stay in place all year.

How to Maintain Your Air Conditioning Unit

Air conditioners require that the filters be kept clean to ensure airflow does not become restricted. The central units are dependent on the same replacement filters as the heating system. You can usually clean the filters of other systems with a vacuum.

You should also inspect the outside of your air conditioner. You should make sure the air conditioner is free of leaves and debris. Also, prune back shrubs.

AC Units are efficient and powerful.

Tones are the unit of measure for all air conditioners, except the smallest. One-ton air conditioner can cool the same amount of water as one ton ice. BTUs can also be used to describe capacity. 12,000 BTUs is equal to one ton for cooling purposes.

An air conditioner’s compressor and fan requires electricity. The more efficient an air conditioner is, the less electricity required to cool one ton. This is known as the Seasonal Energy Efficiency Ratio, or SEER. The SEER is a measure of how efficient a unit is.
