Window AC / September 2, 2018 / Denise Brisette
If there is no central hot air heating then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed then do not force the issue and go another option. Ductless split type air conditioning may be your best option.
Why are window air conditioners so loud? Well the reason is simple: because the entire air conditioner - the compressor the condenser and the fans - are all located in one single unit. By contrast with a split ac and a central air conditioner the compressor and condenser are installed outside of your home. That means that in those units the loudest parts arent in your home. With a window unit however the noisiest parts of the unit are inside your home. This can be a minor annoyance. It may mean that you have to turn up the volume on the tv to hear it. But it can also mean sleepless nights if your window air conditioner in your bedroom is deafening.
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.
