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.

Buyers recommend the TCL Energy Star to people looking for an exceptional air conditioner unit to cool a large space while being on a budget.     

Why it Stands Out to Us

We find the performance of this air conditioner simply exceptional. Its eight-way air outlets provide consistent airflow, thus ensuring perfect cooling to every part of the room. It has an auto-restart feature that ensures that if the power is cut off accidentally, the unit will restart with the previous function settings automatically once the power resumes. This unit will also switch to one of the three modes automatically based on unit setting ad room temperature.

Who Will Use This Most

This unit is perfect for people who value efficiency and performance. This unit uses a 115V outlet, thus eliminating the need to install an expensive 220/240V line. It effectively removes moisture from the air, thus making the environment more comfortable. The three cooling settings make it easier to customize your air-conditioning. It is accompanied by a remote that allows you to adjust the settings without getting up from your comfortable position on the sofa. The 24-hour timer not only increases convenience but also ensures energy savings.   

Bottom Line

The TCL Energy Star is one of the best 15000-BTU air conditioners for people who want an energy-efficient unit. It comes with excellent features such as a long-range remote, filter-cleaning reminder, self-troubleshooting, and much more. It adjusts the temperature and fan speed automatically, thus making the room perfectly relaxing and comfortable. Moreover, it turns off the compressor when the desired temperature is reached, thus conserving energy.

People Also Ask

In addition to the above reviews, people also ask the following questions in order to have a clear idea about which unit will best meet their needs:

How Many Amps Does a 15000-BTU Air Conditioner Use?

A 15000-BTU air conditioner draws an average of 12.5 to 13 Amps.

How Much Area Will a 15000-BTU Air Conditioner Cool?

Air conditioners that support 15000-BTU can cool an area of almost 875 sq. Ft.

Will a 3000 Watt Generator Run a 15000-BTU Air Conditioner?

An air conditioner uses the most wattage as compared to other electrical appliances in your home or RV. Moreover, it requires more wattage to start than it does to keep it running. For a 15000-BTU air conditioner, you will need at least 3500 watts to start and 1800 watts to keep it running. Thus, a 3000-watt generator will not be enough for a 15000-BTU air conditioner.

To comfortably run a 15000-BTU air conditioner, you will need a generator of at least 3300 watts.

A 15,000 BTU air conditioner will consume approximately 1,500 watts per hour if operated at normal settings. The average price of electricity in the United States is 12 cents per kilowatt-hour. Therefore, you’ll pay about 18 cents per hour for the privilege of using your 15,000 BTU window air conditioner. All things considered, that’s not a bad deal at all.

How Many Square Feet Will a 15,000 BTU Air Conditioner Cool?

Good-quality air conditioners with 15,000 BTUs of cooling capacity will normally cool somewhere between 700 and 850 square feet of indoor space. However, this number may be reduced if a room or living area is unusually warm, either from the inflow of sunlight through windows or heat from another source, such as a kitchen.
