Window AC / September 10, 2018 / Francoise Salmons.
The main aspect in the choice of window air conditioner is its cool air performance. You can approximate the required power at the rate of 1 kW per 10 sq.m. with a ceiling height of 2.8 - 3 meters; for household models the characteristic is: from 1.5 - 2 to 6.5 - 8.5 kW. If there is a large glass area in the room windows face south or there are other additional heat inputs one should better buy a model with a power reserve of 15-20%. Another important factor in choosing window air conditioner is room functionality. For example air conditioner installed in the kitchen must be of high performance to provide optimal heat control. Air conditioning unit for bedrooms should have low noise characteristics.
If you choose to use a window air conditioner than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in. As you can tell by now I am not a big fan of window air conditioners. They do have a place for some people. However you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner. Central air conditioning will last much longer be quieter during operation be more efficient be more secure but the initial cost will be higher.
If you already have a window air conditioning unit and you have noticed recently that it seems to be louder there are few steps you should take. Check to see if the unit is vibrating on the windowsill. It may need to be re-tightened on its shelf. The side panels might also be loose. Inspect those to see if they need tightening. If the unit seems to be vibrating more than normal consider sliding a piece of wood under the unit to secure it.

There are other bells and whistles that are available on units these days. These can include features like dehumidifiers to remove moisture from the air and antibacterial filters which can remove odors and bacteria. A final issue to consider if you are looking to buy window air conditioner is what sorts of energy saving features the unit might have. You may consider looking for a unit that has an Energy-Star rating. The EPA assigns an Energy-Star rating to air conditioners that meet certain standards for being cost-effective and guaranteeing energy savings. This can help keep your electricity bills and check even during the hottest days of summer.
