Window AC / September 9, 2018 / Denise Brisette
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.
The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning but the major part of it should be adequate. To use the existing furnace and ductwork a coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will be needed to hook the thermostat the furnace and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
I have seen many units that are not even screwed fast. If the window air conditioner is just there balancing in the window frame it becomes very inviting for a unexpected guest. The window air conditioner is also very inefficient. These units use more power per BTU of cooling than any other type of air conditioner. If you are a light sleeper than chances are you will not want one of these window shakers. Window air conditioners are one of the loudest forms of air conditioning. The blower for these units is very loud when running. Then add the noise of the compressor and you have enough decibels to keep many people wide awake all night long.
