How To Install Small Window Air Conditioner
There's no simpler, more affordable way to cool down a room than with a window-mounted air conditioner. These compact units are reliable, durable, able to absurd nigh whatever size room, and today'southward models are exponentially more energy efficient than units built just 10 years ago. Plus, window air conditioners are easy to install.
🛠Y'all love fixing stuff. We honey fixing stuff. Permit's practise information technology together.
Here, I'll share some tips on what to consider when ownership an air conditioner, and and so how to install it securely and remove it for winter storage.
Size the Room
Window-mounted A/C units come various sizes and cooling capacities, ranging from about 5,000 BTU to 25,000 BTU (British thermal units). Equally a general dominion, you demand about twenty BTU of cooling for every foursquare foot of living infinite. So, for instance, a 12x16-ft. room would require an air conditioner with a cooling capacity of approximately 4,000 BTU (12 10 xvi = 192 sq. ft. x 20 = 3,840 BTU).
Here's a simpler, no-math fashion to determine which size air conditioner to buy. Listed below are the most mutual sizes of window air conditioners for rooms ranging from 150 to one,600 square feet:
It's critically important to choose a model with a cooling capacity sufficient to cool the room. If you choose a unit that's too small, it'll struggle to keep the room cool on the hottest days. And choosing a unit of measurement that's too big—a common fault—is only every bit problematic.
An oversized air conditioner will pump too much wet back into the room, raising the humidity to unsafe levels, particularly for those with breathing difficulties. Excessive wet can besides create a breeding basis for grit mites and mold. Plus, a too-large A/C unit is louder and burns more electricity than a properly sized unit of measurement.
Buy the All-time
If you're looking for a new window A/C, well, you're in luck.
Summer might be hot, just so is the competition to sell these appliances, with anywhere from 1.74 million to 5.4 million being sold in whatever given year recently, according to statista.com and U.S. Department of Free energy.
That competition helps you, equally manufacturers hold down prices and outbid each other to add together features such as voice control, app control, hand-held remotes, timers, and features like a dehumidifier setting. Bells and whistles are squeamish, but more so is the increased free energy efficiency of these appliances.
Cheque Your Window
Most window-mounted air conditioners are designed to fit into double-hung windows, simply virtually units tin also exist placed in swing-out casement or sliding windows. (Cheque with the air-conditioner manufacturer for specific installation instructions.) Here, I'll hash out installation for double-hung windows, which are by far the most pop style of window.
Starting time by raising the lower sash, and so measure out the height and width of the opening. Exist sure to have those dimensions on hand when shopping for an air conditioner to ensure information technology'll fit comfortably into the window. Also, keep fire prophylactic in listen when deciding where to install the air conditioner: Don't place it in an egress window that serves as the only means of escape should a fire erupt.
Consider Free energy Efficiency
The energy efficiency of a room air conditioner is designated by its EER number, which stands for Energy Efficiency Rating. The EER is calculated by dividing the unit's BTU rating by the wattage of the unit. For example, a 12,000 BTU air conditioner that uses 1,200 watts of electricity has an EER of 10.
⚠️ Don't confuse EER with SEER—Seasonal Energy Efficiency Ratio—which is used to calculate the free energy efficiency of primal air-conditioning systems.
Window A/C units typically have ratings between virtually viii and 12. A rating of ten or higher is considered ideal for saving electricity and lowering your utility bills. And be certain to await for features such equally digital temperature controls, variable fan speeds, and slumber settings, which also can help conserve power.
Installation
Installing a window air-conditioner is all-time done with two people. Even small-scale air conditioners are heavy and bad-mannered to lift. And the last affair you desire is for your A/C unit to fall out window or onto the floor.
💡 Salve the air conditioner's original box and packing materials; y'all can use information technology later for storing the unit.
Start past reading the installation manual and familiarizing yourself with all the included hardware and fasteners. Most units come with a kit that includes adaptable window extensions and metal mounting brackets. These parts will ensure a secure and closed fit in the window opening. And for additional support, especially for larger air conditioners, consider purchasing a steel support bracket and mount it to the exterior firm wall, direct beneath the windowsill.
Raise the window'due south lower sash and set the A/C unit centered on the windowsill. Well-nigh the weight will be hanging out the window, and then exist certain to keep a house grip on the unit. Now pull down the lower sash until information technology contacts the top of the A/C unit direct behind the metallic flange running across the tiptop of the unit. Keep downward pressure on the lower sash; it'due south preventing the unit from toppling out the window. The installation kit typically includes two small L-shaped metallic brackets, which are used to forbid the lower sash from existence raised.
Set one bracket on the far left, top edge of the lower sash. So, employ a cordless drill to screw the subclass to the upper sash. Repeat to install the remaining bracket to the far right side of the lower sash. Depending on the A/C unit, you may besides need to drive brusk screws through the metal flange running across the elevation of the unit and into the lower sash. With the brackets screwed in place and the lower sash locked in positioned, and the A/C unit is secured.
Adjacent, attach the 2 piano accordion-like extensions, one to each side of the A/C unit. (Note that in some cases you must install the extensions prior to setting the unit in the window; check the installation manual for specific details.) Pull out each extension to close off the space to the left and right of the air conditioner. Screw the vertical mounting flange of each extension to the window jambs. Take the thick foam-rubber conditions stripping and stuff it into the gap along the top edge of the lower sash to cake out insects and hot air.
When properly installed, the A/C unit of measurement volition tip slightly to the outside. This is of import to allow condensation to drip outside, not into the room.
Power It Up
Air conditioners draw a fair amount of electricity, so be mindful of the circuit into which you lot plug the unit of measurement. If the same excursion powers other high-energy appliances—refrigerators, dryers, ovens—consider plugging in the air conditioner elsewhere. If you're using an extension string, it's important to use a string that's specifically designed to handle the electric load; these heavy-duty cords are usually labeled equally, "air-conditioner cord" or "major-appliance cord."
And be certain to check the air filter monthly throughout the cooling season to ensure it's clean and clear of obstructions.
Removal for Storage
Removing a window air-conditioner unit of measurement can be difficult, and then unless y'all really demand access to the window or desire to create a better seal for winter, it'due south best to go out information technology in place and protect it with a slip-on comprehend.
If you decide to remove the air conditioner, again, it's best to have two people. Start by reversing the installation steps, but be very careful non to unscrew the two minor L-shaped brackets until y'all've slid the air conditioner into the room far enough so that it's resting deeply on the windowsill and not tipping in or out.
After removing all the hardware, raise the lower sash and elevator the air conditioner out of the window and gear up information technology onto a thick blanket spread on the floor. Vacuum the outside of the unit of measurement—especially the louvered vents—and then wipe it down with a damp fabric.
Place the air conditioner back into its original box, using the dense-foam packing fabric to protect information technology from harm. Put all the screws, brackets and other installation hardware items in a re-sealable plastic bag, and put the purse in the box. Fix the box in a absurd, dry place for the winter. And if the storage room has a physical floor, identify two 2x4s beneath the box to raise it up and protect information technology from moisture.
