What Is The Smallest Window Air Conditioner?

Those who live in outdated homes without the comfort and convenience of central air know how punishing it can be to sleep in a hot bedroom during a heatwave. 

While a fan can help, a small window air conditioner is better.

These small yet powerful appliances emit approximately 5,000 BTUs of energy, which is sufficient to chill most bedrooms. In addition, they are smaller than larger units and can fit in window openings as tiny as 21 (twenty-one) inches wide and 14 inches high while also being significantly less expensive.

The smallest window air conditioner is MIDEA MAW05M1BWT measuring 13.19″ (W) x 12.05″ (H) x 15.98″ (D). Despite its small size, this air conditioner is ideal for most conventional windows with a width ranging from 23 to 36 inches and an open window height of 13 inches.

What is Considered a Small Window Air Conditioner?

A small window air conditioner has a width of 14 to 23 inches and a height of 11 to 15 inches. The smallest window air conditioners are designed to fit casement, sliding, and double-hung windows.

When shopping for a tiny window AC unit, consider the BTU output. The smaller the window air conditioner, the lower the BTU output. The BTU capacity of small window units ranges from 5,000 to 12,000 BTU.

Any window air conditioner that produces more than 12,000 BTUs is likely to be 24 inches or more comprehensive and hence cannot be classified as a small window air conditioner.

  • 15″ (W) x 12″ (H)

  • 23″ (W) x 15″ (H)

How to Choose the Right Size Window Air Conditioner?

When determining the optimal size of the window air conditioner for your needs, two factors must be considered: the size of the window installed and the BTU capacity for total square footage coverage.

Calculate the Size of the Window

To ensure a proper fit with your air conditioning unit, acquire accurate measurements of the window you intend to install the AC unit. To acquire the most incredible fit, the height and breadth of the window are the most critical dimensions to take.

To get the width of a double-hung or casement window, measure between the two inner sides of the casing near the sill plate. Because not all windows are completely square, taking measurements around the window sill will be the most accurate for your needs.

If the window is tiny, the height must also be measured. Again, this measurement should be taken with the window completely open. Open the window and measure between the sash edge and the casing to measure a sliding window.

Select the Appropriate BTU Capacity

The BTU production and the size of the AC unit are inextricably linked. Therefore, the BTU output also determines the number of square feet the air conditioner can successfully cover.

Choosing the wrong BTU output can result in the wrong size unit, causing you to run an over or undersized air conditioner.

An oversized window air conditioner will cost more to buy and consume more energy than is required to run. It will also perform poorly in terms of dehumidification because the unit will not be able to function for long enough to remove moisture adequately.


How to Install a Small Window Air Conditioner

How to Install a Small Window Air Conditioner

It’s time to chill down—in your room after you’ve decided to purchase a small window air conditioning unit for your space. But, first, gather the equipment and materials specified above and keep them close at hand—you don’t want to pick up a large piece of machinery only to discover that your screwdriver is in another room.

Step 1: Take A Measurement Of Your Window

Measure the height and width of the window opening before shopping for a window air conditioner. The air conditioner you buy should have at least 2 inches of wriggle area on both sides of the housing so that the unit’s baffles may be extended.

Step 2: Put The Device Together

You’re ready to install an air conditioner after purchasing and unpacking it. Attach any rails, flanges, or accordion-style panels to the unit’s housing first. Then, use the screws given by the manufacturer and follow the manufacturer’s instructions.

You’ll need a helper from now on: two pairs of hands are preferable for all but the tiniest air conditioners.

Step 3: Get Your Window Ready

Open the window broad enough to allow for the air conditioner’s height. Next, lift the unit and place it on the bottom of the window frame. Finally, let your assistant hold the device in position while completing the remaining chores.

Step 4: Insert The Device Into The Window

Most window air conditioners have two flanges: one at the top and one along the bottom. These flanges facilitate installation and increase the stability of the air conditioner.

Place the bottom flange so that it touches the windowsill. Next, lower the window sash (which you lifted in Step 2) until its bottom rail hits the unit’s top flange. The top window sash should now hold the air conditioner in place. Still, ask your assistant to stabilize the unit until you finish the next step.

You may also need to install a window AC unit mount support bracket depending on the design of the window and the size of the AC unit. Again, consult the air conditioner manufacturer’s instructions—and, if appropriate, your building’s air conditioner installation regulations—to determine whether this device is necessary for your installation.

Step 5: Install The Angle Brackets

Your air conditioner most likely arrived with one or two little angle brackets that connect the two window sashes. These brackets are critical because they keep the sashes from separating and the window from being mistakenly opened. Both conditions are hazardous and could result in the air conditioner falling out of the window.

Place the angle bracket where the top sash meets the top of the lower strap. Mark the location of the screws with a pencil, drill pilot holes, then tighten the screws with a screwdriver.

Next, extend the accordion-style panels (which you attached to the device in Step 2) and fix them to the window with the screws provided by the manufacturer. At this point, double-check that everything is in order.

Step 6: Put The Panels Together

Extend the panels on either side to cover the gap once the air conditioning unit is securely mounted to the window. Use foam weather stripping to make an airtight fit if there are still small cracks and gaps around the panel. 

Locate the tiny mounting holes on the panel once you’re pleased with its positioning—Drill small pilot holes in the sash that line up with the mounting holes. Then, using two screws and a screwdriver, secure the panel to the strap.

If your air conditioner does not come with an air conditioner screen, you may need to buy a window AC installation kit. Alternatively, you can build a window AC.

Step 7: Use A Window AC Seal To Insulate The Aperture

The next stage is to close the gap between the upper and lower sashes, which have been raised to accommodate the unit.

At least one foam insulating strip should have come with your air conditioner. First, cut it to length, then fit it tightly between the bottom sash and the top sash’s glass panes.

If your air conditioner did not arrive with an insulating strip, consider purchasing and installing one.
