Email Reddit A 12,000 Btu air conditioner can cool a 500-square-foot room. The cooling capacity of air conditioners is measured in BTUs, or British thermal units.

The more Btu of capacity, the larger the room the air conditioner can cool. Scientifically, one Btu is the amount of energy required to change the temperature of 1 pound of water by 1 degree Fahrenheit. In terms of air-conditioner capacity, the rule of thumb is that it takes around 25 Btu to cool 1 square foot of room floor area. Air Conditioner Ratings The most common window air conditioning units come in cooling capacities ranging from 5,000 to 12,000 Btu. A 12,000 Btu air conditioner can cool between 450 and 550 square feet of floor space. A 12,000 Btu unit could cool a room 25 feet long by 20 feet wide that has 500 square feet of floor area. Manufacturers give their own ratings as to how much room area they believe their units can cool. Actual Performance Varies An air conditioner’s cooling capability is affected by your environment and certain physical characteristics of the room being cooled. Your unit’s cooling ability varies depending on your climate and weather, amount of wall and ceiling insulation, the direction windows face, the number of windows and number of occupants.

Our ac covers are available in a round or square shape and in all four of our unique materials.WHEN the heat and humidity of summer take hold and it’s time to hit the “cool” button, you’ll want your air-conditioner to respond with a blast of chilly air and a satisfying hum.Doing some maintenance now can help make sure that happens.The first step, albeit a simple one, is often overlooked: Make sure the unit isn’t still wearing its winter coat, advised Richard H. Toder, executive director of T/S Associates, a Manhattan heating and air-conditioning company. “You wouldn’t believe how many people forget to take off the cover and end up burning their unit out,” he said., a home-improvement Web site.Look to see that weeds or bushes have not grown too close to the compressor, he said, and that no debris has been sucked up into the coil. The compressor should have at least a few feet of clearance around and above it, and its fins — a series of thin metal strips like those on the back of a window air-conditioner — must be free of dirt and debris.

Next, remove the unit’s filter and either clean or replace it. If the filter isn’t clean, the workings can become caked with dust, significantly reducing the unit’s efficiency. In window units, the filter is either a custom-fit plastic-framed fiberglass filter that can be washed and dried, or a plain foam one that Mr. Toder says should be replaced instead of cleaned. Buy a new one at a home center or hardware store for a few dollars and cut it to size.In central air systems, the filter is in the air handler, which is typically in the basement or attic. The filters — which often are also the furnace filters — come in specific sizes and can be found in hardware stores or home centers.“You don’t have to get a really expensive filter, as long as you resolve to change it every 30 days,” Mr. Carter said. A medium-price filter, costing about $5, is probably sufficient, he said. Most experts say it’s also important to clean the inside of the unit — particularly the evaporator coils, which look like a coil of copper tubing — with a vacuum cleaner or a soft brush.

With a window unit, that may involve removing the front cover to get to the coil; with a central air unit, you may need to take the cover off the housing of the evaporator coil. If that seems too complicated or difficult, call a professional.Peter Varsalona, a principal of Rand Engineering & Architecture in Manhattan, said that air-conditioners installed in sleeves through the wall — as in many apartments — can usually slide out of the sleeve and be cleaned.Once clean, the air-conditioner can be tested to make sure it still cools adequately. For a window unit, the test couldn’t be more simple. “Wait until the temperature is about 70 degrees outside, turn the unit on, wait a couple of minutes, and if it’s blowing cold air, it’s working,” Mr. Carter said.Tom Kraeutler, a co-host of the syndicated radio program “The Money Pit,” offers a relatively simple test for a central unit. Once the outdoor temperature reaches about 60 degrees, turn the unit on, let it run for 10 to 15 minutes, then put one room thermometer near a vent where the air is coming out, and another at one of the return vents, where air is pulled back to the unit.“
