Sizing Central Air Conditioning

Many new homes have air conditioning units in them these days, which is a good job considering global warming and the effect that it has on our homes these days. However, some new builds and older homes may not have air conditioning units. If this is the case, you may be considering installing one and have several questions about it.

The main question that homeowners do ask when considering buying an air conditioning unit is how big it should be. This is certainly a dilemma these days, for more reasons that one.

Buying the right air conditioning unit is not a matter of going out and buying the biggest and best unit in the store anymore. Instead it is a matter of going and buying the right one to fit all of your wants and needs.

You have to assess just how energy efficient it has to be in order to help the environment and save you money on your energy bills. There are also often concessions applied to installation is you do purchase one of the more energy efficient models You also have to consider a number of other factors including the following:

    • The size of your home and if indeed the air conditioning is to be used in your whole home or just certain rooms. Some individuals actually use air conditioning in the main rooms used like the lounge and bedrooms and not the basement or any extras rooms that are often used for show.

    • The nature of the existing insulation. For example, if your home is already well insulated then you will not need as powerful an air conditioning unit. Assessing the attic and walls, as well as the age of the existing insulation, can give you an idea of the insulation levels.

    • The window efficiency can also make a difference because heat may be lost via the windows or, similarly, kept in. The efficiency of the windows will determine how powerful an air conditioning unit you need.

    • The level of shade and aspect of the house will also affect the level of air conditioning you need.

Of course, there are perhaps more factors to consider as well. For example, do you need winter heating as well as summer cooling, or just cooling. You may already have another heating system in place, in which case you would be throwing good money away.

If you need both then you should be looking for air source heat pumps. If not, then you will need a traditional air conditioning unit. Also, regardless of the one you buy, it should be in accordance with the Air-Conditioning Contractors of America or the American Society of Heating, Refrigeration and Air-Conditioning Engineering, Inc. (ASHRAE) guidelines.

After assessing all of the factors that are laid out above, go to a store that sells air conditioning units and present a member of staff with your needs. All of them should be highly trained and will be able to advise you.

The sizing of the air conditioning unit you should buy directly relates to all of the factors above and should conform to the 100% so that you get everything you need in one energy efficient package. After all, you should only invest in an air conditioning unit once and make the most of it. Your energy bills and hoe comfort depend on it.
