Window AC / August 28, 2018 / Jacqueline Bizier
A window air conditioner in my opinion is a last resort for air conditioning your house or building. There are many down sides to window air conditioning units. There are two good things that window air conditioners have going for them. They are very inexpensive when it comes to cost per BTU of cooling. They also install very quickly and easily. That is where the good part of them ends. Window air conditioners are security risks. If a thief wants to get into your house the thin sheet metal box that holds the unit in the window can easily be pulled apart to get in through the window.
When purchasing a window air conditioner it is very important to purchase one with the proper cooling capacity. An air conditioner that is not properly sized will not work as efficiently as one that is sized properly. This is one of the most common mistakes made when selecting air conditioners. Use an air conditioner size calculator to select the proper sized unit for the room you want to cool. Undersized air conditioners will run continuously and not cool the space adequately and an oversized unit will cycle on and off too often. This increases equipment wear and can actually cause fuses to fail.
An additional benefit of a properly sized air conditioner is humidity control. While these units are operating moisture condenses on the evaporator coil just like a dehumidifier. Probably the most common problem with window air conditioners is that they sometimes develop rattling noises due to vibration. This is not a serious problem and can be rectified very easily by checking to make sure all screws are tight and check that the unit is mounted correctly in the window and not twisted or stressed. Air Conditioning is something that many people look at installing every year. There are many options when it comes time to make that decision.
