Picking an air conditioning unit can be very confusing and when it comes to choosing just what is right for a house, there are many factors to take into consideration. The proliferation of air conditioning units in the market make it really difficult particularly if you have no experience with the installation of an air conditioning unit. As important as the manufacturer might be, there are several other factors that should be considered before choosing an air conditioning unit.

State of the House

This is a major consideration as it will affect all the other factors that go into choosing an air conditioning unit. The size of the house matters because that will determine what type of unit should be installed. But more important than the size of the house is the state of the house. If it is already fitted for an air conditioning unit, that makes the job of choosing one a bit easier. However, if the house does not come already fitted, this might mean that retrofitting the house for installation should be considered. On the other hand, a ductless central air conditioning unit could also be used. Most homes in the U.S are built for ready installation of an air conditioning unit.

Type of Unit

What type of air conditioning unit is best suited to the house in question? The choice can be made between a portable unit, one that is installed for one or two rooms and a central cooling unit. The choice would depend largely on the house and the climate in which it is located. With each summer becoming hotter than the previous ones, most people usually opt for a central air conditioning unit. A quieter sounding unit might also be an important factor.

Size of Unit

In this case the size means the cooling capacity of the air conditioning unit. This is really important because the cooling capacity of an air conditioning unit should match the cooling area. The capacity should neither be bigger than nor smaller than the cooling area as this leads to a loss of efficiency in cooling.

Energy Efficiency

The U.S Department of Energy (DOE) stipulated that the minimum rating number for an air conditioning unit should be 10. This is measured by what is known as the Seasonal Energy Efficiency Rating (SEER) and can be seen on most units. As a matter of facts, newer models tend to contain the SEER number in the name of the model.

The energy efficiency is an important consideration because in most circumstances, the cost of the air conditioning unit would depend on how high the SEER number is with a 14 costing more than a 10 for instance. Although this might make one pause a bit, it is important to remember that a high energy efficiency air conditioning unit saves money in the long run.

Before choosing an air conditioning unit, it might also be prudent to contact an expert for advice on more technical details. This can be done after using the factors listed in narrowing down choice.
