Although the small window type air conditioner is suitable for small bedrooms, it cannot complete the work in the larger living space, especially in the heat wave. For hotter climates and larger spaces, you need a 10,000-BTU air conditioner that can cover up to 450 square feet.

These medium-sized window units can fit into openings as narrow as 24 inches wide and 14 inches high. Provide optimized air conditioning to achieve sleep, energy saving and quiet modes. The smart air conditioner is connected to the home’s Wi-Fi so that it can be operated by smart devices wherever there is an Internet connection.

This guide provides important factors to consider when buying the best 10000-BTU air conditioner, and reviews some of the top options on the market.

All 10000-BTU air conditioners can cool down to 450 square feet, but this does not mean that every model is the same. Many factors make these appliances unique, such as temperature settings, operating modes, and energy efficiency. Learn about these and other key characteristics of 10000-BTU air conditioners in advance.

Window air conditioners have analog or digital temperature control.

There are large vents at the front of the window air conditioner, which can suck in air from the room. The air filter in the vent can capture dust, pollen, pet dander and other impurities, thereby protecting the machinery of the equipment and improving the air quality in the room. The filter may become clogged with debris and dust and needs to be replaced regularly.

After the air passes through the filter, the compressor cools it; then blowers and vents send it back to the room. Adjustable vertical and horizontal blinds on the vents can direct the airflow in four different directions.

While cooling the air, the air conditioner will also dehumidify the space. The condenser removes moisture from the air, which collects on its coil. The water passes through the drainage system inside the equipment and leads the water to the outdoors.

Some air conditioners also have a dehumidification mode, which uses a compressor to remove moisture from the air. This setting reduces the ambient humidity to 40% to 50% without blowing cold air into the room. Since a condenser is not required to maintain the temperature in the room, the air conditioning unit uses less energy in the dehumidification mode.

Window air conditioners are one of the larger energy pigs in the family. A 10,000-BTU air conditioner requires 800 to 1,250 watts of energy, which may cause a significant surge in summer energy bills.

The 1,250-watt air conditioner that runs for 8 hours a day uses about 300 kilowatt-hours of energy per month. Since the average electricity bill is 12 cents per kilowatt-hour, the air-conditioning unit will increase the electricity bill by approximately US$36 per month.

Most shoppers are looking for energy-efficient window air conditioners. All appliances, including air conditioners, have an energy efficiency rating (EER). Any air conditioner with an EER rating of 9 or higher has an above-average efficiency. The most energy-efficient appliances have Energy Star certification, which means they have an EER of at least 12.

Many manufacturers list the efficiency rating of the equipment on the packaging. To calculate it, simply divide the BTU output by the wattage. For example, the EER of a 1,000-watt 10000-BTU air conditioner is 10.

In addition to standard temperature control, the best 10000-BTU air conditioners may have some additional features to optimize operation.

Window air conditioners use built-in air compressors and blowers to generate and distribute cold air, both of which generate noise. The average operating speed of the window air conditioner is about 60 decibels, which is about the same as the noise level of normal conversation, but the volume is enough to affect sleep or watching a carnival.

Many air conditioners have a silent mode, which reduces the decibel level to around 50. Although useful, silent mode generally reduces fan speed and compressor output, which means the air will not be as cool.

Different from other types of air conditioners, these air conditioners need to install copper pipe connections, open holes in the wall, hard-wire to the home's electrical system, and even use Freon to charge the compressor. It is relatively easy to install window air conditioners.

Install the window type air conditioner on the window sill, with part of the equipment passing through the window and part of the equipment in the room. The lower frame of the window is closed to lean against the top of the window unit to fix it in place.

Install weather strips to form an airtight seal between the window and the air conditioner and bracket to prevent the air conditioner from falling out of the window. The user must also install adjustable panels extending from the side of the air conditioner to cover the gaps in the window openings on both sides of the device. Most window fittings plug into a standard 115-volt socket, and installation usually takes about 30 minutes or less.

Maintenance includes regularly removing the large vents inside the air conditioning equipment, as well as removing and cleaning reusable filters. Once a year, the owner should remove the air conditioner cover and wipe the coil.

All 10000-BTU air conditioners in the following list include a digital thermostat and many useful operating modes. Some have smart features, Energy Star ratings, and stylish designs. Any of these models can cool up to 450 square feet of space.

Energy efficiency, precise temperature control and low noise output make this LG window air conditioner an excellent all-round 10000-BTU window air conditioner. LG's models have a digital thermostat that can set a specific temperature and prevent spikes and drops in the room temperature.

The remote control includes on/off buttons and temperature, timer, fan speed and operation controls. As an Energy Star rated device, its operating noise is only 52 decibels, similar to a refrigerator in operation.

Frigidaire's 10000-BTU air conditioner is affordable and fully functional. Thanks to its Energy Star rating, air conditioners can also save money on the back end. The digital thermostat provides precise temperature settings, including a series of operating modes, including sleep and energy saving modes, and an automatic on/off timer.

For convenience, use the control panel to set each mode and remote control. When the filter needs to be cleaned, the indicator light on the control panel will light up.

As one of the most customizable air conditioners on the market, Koldfront has a variety of operating modes and functions. Digital thermostat can realize precise temperature control. Operation modes include sleep, energy saving and dehumidification. Switch each mode through a large control panel that displays air conditioning settings. The remote control can be easily adjusted from the entire room.

The 24-hour timer helps save money and keep the room cool only when needed. Koldfront is suitable for window openings as small as 15.5 inches.

Can not. The wheeled room air conditioner is usually located in the room, and there is a pipe in the room that extends from the device to the outside of the house to drain the condensed water. The window air conditioner unit must be installed in the window of the room.

Q: How many square feet can the 10000-BTU air conditioner cool?

All 10000-BTU air conditioners can cool up to 450 square feet of space. Since the window unit blows cold air from the unit, it can cool a single open space instead of multiple rooms.

Install weather strips between the air conditioner and the window sash and the window sill to close any gaps that may allow air to pass through. Make sure that there is no gap between the window frame and the panels on both sides of the air conditioner.

To clean the window air conditioner, follow these steps:
