How to Choose a 15,000 BTU Air Conditioner

Window air conditioners are a popular item. Consequently, there are a lot of options available on the market. Several factors should determine your choice, based on your personal needs and preferences:

Energy Usage Rates

Energy-efficient window air conditioners are usually certified through the federal government’s ENERGY STAR® rating system. These units will consistently outperform the competition, keeping your home cool while consuming ten percent or less electricity.

As a general standard, energy efficiency is identified by an air conditioner’s Energy Efficiency Rating, or EER. When comparing various 15,000 BTU units, always remember that the A/C with the higher EER will save you more money.

Size of the Space to Be Cooled

Window air conditioners with a 15,000 BTU cooling capacity are recommended for entire floors, rooms, or apartments in the 550-1050 square feet size range.

If you’re trying to cool an area on the high end of that estimate, a 15,000 BTU unit may not be powerful enough if other factors cause an increased heat effect. These could include ample sunshine penetration through windows, proximity to the kitchen, or having numerous people occupying that space for much of the time.

Installation Requirements

Standard window air conditioners can only be installed in single-hung or double-hung windows. These have window sections that move up and down vertically. Window A/Cs can also be installed in wall sleeves particularly intended for that purpose.

If your home or apartment has neither the proper windows nor a pre-existing wall sleeve, you could have the latter installed. You just have to be sure to install the sleeve in a wall that opens to the outside, so the A/C can vent properly.
