Wall air conditioners offer the same benefits as room air conditioners and don’t require that you have a conveniently-placed window in which to install a unit. Wall air conditioners are less expensive than central air conditioning units, provide cooling capabilities of up to 18,000 BTU/hour, and can cool a room as large as 1,000 square feet. Some wall air conditioners are even large enough to cool an entire small house, provided that properly-placed, portable fans and appropriate insulation are used. A wall-mounted air conditioner works in the same way as window air conditioners. Two fans blow air over hot and cold Freon-filled coils. The hot coils condense the Freon into a liquid, which then runs through an expansion valve and evaporates, which creates cold Freon gas. The cold gas absorbs warm outside air, cooling it and blowing it into the room to lower the room’s temperature. As a by-product of this process, the air conditioner also removes excess humidity from the room, making it feel even cooler and more comfortable.

A wall-mounted air conditioner preserves your window view and allows you to open the window when it’s cool enough outside that air conditioning is unnecessary. Also, because wall air conditioners stay in place year-round, they offer easy, one-time installation. Finally, because it never leaves the wall, there’s no need to store a bulky AC unit in another location such as your attic or basement during the off-season. This makes a wall-mounted AC a particularly good option in regions that experience all four seasons. Wall air conditioners provide more installation options than window units. Place a wall-mounted AC unit on any outside-facing, sheetrock wall that does not have any existing pipes or electrical lines running through it. With the help of a qualified electrician, it’s even possible to move electrical lines to accommodate an AC unit if necessary. Because the installer will have to cut a hole in the wall, a wall air conditioner cannot be mounted on a stone, brick, or concrete wall.

Also remember to mount the unit near an electrical socket, as it has to plug into either a 115-volt or 230-volt household circuit, depending on the air conditioner size. A larger air conditioner requires its own circuit, while a smaller unit may share a circuit with smaller appliances (but not major appliances such as refrigerators and dishwashers).10000 btu ac window unit Unplug the AC when not in use in order to keep it from drawing electricity and raising your power bill. trane central ac unit pricesFor the most energy-efficient cooling and cost effective air conditioning, look for wall air conditioners with an Energy Star rating.auto ac repair in mcallenEnsuring human comfort, productivity, and safety, while practicing environmental stewardship is the mission of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).

If you’ve ever installed a window air-conditioning unit in your old apartment, you know that your AC is inexplicably heavy for the small space that it cools.

It takes a lot of copper to produce all that cold air, Kelly explains. Her original piece, from 2011, is reprinted below. With temperatures rising, Americans have begun the annual summer tradition of installing cumbersome removable air conditioners. It's tough to find a window unit that's lighter than 46 pounds—and a machine like that would be able to cool only a fairly small room (150 square feet or less). What makes them so heavy?Air-conditioning systems—both centralized ones and window units—have three important components: an evaporator, a condenser, and a compressor. The evaporator helps cool the air, the condenser readies the refrigerant for the cooling process, and the compressor moves refrigerant back and forth between them. The evaporator and the condenser are both made out of copper coils, and there is some copper in the compressor, too. Copper is pretty heavy, weighing some 558 pounds per cubic foot, and the copper components account for as much as 60 percent of the weight in smaller units—though the percentage declines as they get heavier.

(Units can be as massive as 213 pounds, the weight of the heaviest window unit sold by the Friedrich Air Conditioning Co.) Steel, which provides structural support and houses or covers the compressor, accounts for the rest of the weight. Aluminum, which weighs about 169 pounds per cubic foot, could theoretically be substituted for copper. But manufacturers continue to use copper because it's a better conductor of heat. (That's important because an air conditioner works by essentially removing heat from the air.) Furthermore, the cost of an air-conditioning unit would increase if manufacturers used aluminum because of the new equipment and employee training they would have to invest in to make the necessary parts. Additionally, so much more aluminum would have to be used—to ensure that passageways in the unit were thick enough to withstand the high-pressure refrigerant moving through them—that units might not be that much lighter. Mechanical engineers aren't particularly interested in making lighterunits.
