Central air conditioners set the standard in today's air conditioning market. Besides helping to keep you cool, they also filter and dehumidify the air around you. This is really beneficial if you have problems with allergies or even asthma.
Before buying a central air conditioner, you need to know which size air conditioner you need. This will all depend on the size of the room that needs to be cooled. To determine the right size air conditioner for you, you should get in touch with a contractor. A contractor can quickly determine which size air conditioning unit is right for you by using the "manual j" calculation method.
When shopping for central air conditioners, you'll find that they have different seer ratings. Seer stands for Seasonal Energy Efficiency Ratio, this lets you know just how efficient the air conditioner is. Newer air conditioners probably won't have a seer rating below 13. However, some of the older units that are still around and were installed many years ago could have a seer rating as low as 7.
If you're planning on replacing an older model for a more modern central air conditioning unit, you could actually save large sums in cooling bills. It's estimated that upgrading an air conditioner that as a seer of 11.5 to a unit with a seer of 13 might save you around $500 on electric bills each year!
As well as making sure you choose an air conditioner that is the correct size, care needs to be taken where the unit should be installed. Where you position you're air conditioner could affect how efficient it will be. If it gets enclosed by much vegetation then the air won't be able to flow freely enough.
