Installing a window AC yourself shouldn't be a struggle. These conventional units feature complete mounting kits and clear instructions designed for a straightforward setup.

Conventional window air conditioners for easy installation save you an afternoon of measuring, drilling, and second-guessing, which matters most to renters, first-time buyers, and anyone setting up a unit without help. The models in this guide ship with mounting hardware, and the top picks state the window range they fit, so you can confirm compatibility before the box arrives. For more options across the category, see our conventional window air conditioners section.
Easy installation comes down to a few concrete things: a published window width and height range, an included kit, a manageable weight, and standard household power. We weighed those first, then compared cooling capacity against room size, controls, and efficiency where it is listed. Smaller units are naturally easier to lift and secure, so the top picks lean toward bedrooms and home offices, with one option for medium rooms.

Top 3 Conventional Window Air Conditioners for Easy Installation Reviewed
#1 Midea 5,000 BTU EasyCool Window Air Conditioner: Best Overall
Why We Picked It
The Midea 5,000 BTU EasyCool Window Air Conditioner takes the top spot because its listing answers the key installation questions up front. It fits windows 23 to 36 inches wide with a minimum height of 13 inches, all mounting accessories are included, and it weighs 35.3 pounds, light enough for most people to position and secure. The only tool you need to supply is a screwdriver.
Once it is in, mechanical controls with 7 temperature settings and two cooling and two fan-only speeds mean there is no remote to pair or app to configure. It lists a CEER of 11.0 and carries 4.4 stars from 12,210 ratings. Compared with the GE pick it offers similar capacity plus a published efficiency rating; compared with the Frigidaire, it suits a smaller room.
Key Specifications
- Cooling Capacity: 5,000 BTU
- Room Size: Up to 150 sq. ft.
- Window Fit: 23 to 36 inches wide, 13 inches minimum height
- Efficiency: CEER 11.0
- Weight: 35.3 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
The listing notes that a screwdriver is required but not included, and some window frames need pilot holes before the screws go in, so read the manual first. The spec sheet gives a narrower maximum window width than the feature list, so measure carefully and confirm the range in the included manual. With 5,000 BTU, it suits rooms up to 150 square feet only.
Best For
Renters and first-time buyers cooling a small bedroom, dorm room, or home office who want the simplest possible setup.
For a straightforward small-room install, check the Midea 5,000 BTU EasyCool Window Air Conditioner.
#2 GE 5,000 BTU Window Air Conditioner: Best for Double-Hung Windows
Why We Picked It
The GE 5,000 BTU Window Air Conditioner is built around an EZ Mount installation kit and a fixed chassis designed for double-hung windows from 21.875 to 36 inches wide and 13.375 inches high. That lower minimum width than the Midea helps if your window is on the narrow side. At 36 pounds, it is nearly as easy to handle as our top pick.
It delivers 5,100 BTU of cooling for rooms up to 150 square feet, with two cooling modes, two fan speeds, and 10 temperature settings on simple controls. GE describes it as low-noise and suited to nighttime use, and it carries 4.3 stars from 7,337 ratings. Against the Midea, it trades a published efficiency rating for a wider window range; against the Frigidaire, it covers a smaller room.
Key Specifications
- Cooling Capacity: 5,100 BTU
- Room Size: Up to 150 sq. ft.
- Window Fit: Double-hung, 21.875 to 36 inches wide, 13.375 inches high
- Installation: EZ Mount kit, fixed chassis
- Weight: 36 pounds
| Pros | Cons |
|---|---|
|
|
Things to Consider
The listed installation is for double-hung windows, so confirm your window style as well as its size before ordering. The fixed chassis is standard for window units, but it means the whole unit lifts in and out at the end of the season. Plug it into a standard 115-volt outlet as the manual directs, and do not use an extension cord.
Best For
Small-room owners with standard double-hung windows, especially narrower ones, who want a light unit and a dedicated mounting kit.
For an EZ Mount install in a double-hung window, see the GE 5,000 BTU Window Air Conditioner.
#3 Frigidaire 8,000 BTU Window Air Conditioner: Best for Medium Rooms
Why We Picked It
The Frigidaire 8,000 BTU Window Air Conditioner is the pick if your room is too large for a 5,000 BTU unit. It is rated for rooms up to 350 square feet and measures 15.8 inches wide and 13.4 inches high, a compact chassis for its capacity. Once it is mounted, the remote control, 24-hour timer, and Clean Filter alerts make day-to-day use simple.
It adds 6-way directional airflow, three fan speeds, Eco Mode, Sleep Mode, and Dry Mode, and it operates at 54 dBA, quiet enough for a bedroom or small living room. It carries 4.3 stars from 213 ratings. Unlike the Midea and GE, its listing does not state a window range or unit weight, so it takes a little more homework before you buy.
Key Specifications
- Cooling Capacity: 8,000 BTU
- Room Size: Up to 350 sq. ft.
- Noise: 54 dBA
- Airflow: 6-way directional
- Controls: Remote with 24-hour timer
| Pros | Cons |
|---|---|
|
|
Things to Consider
Because the listing does not give a window width range or unit weight, check the manual or the manufacturer’s specification sheet before ordering, and measure your window opening against the unit’s 13.4-inch height. It runs on 115 volts. In a room well under its rated size it may cycle often, so match capacity to the room.
Best For
Homeowners cooling a larger bedroom or small living room who want remote control and quiet operation after a standard window install.
For medium-room cooling with easy everyday controls, review the Frigidaire 8,000 BTU Window Air Conditioner.
How to Choose a Conventional Window Air Conditioner for Easy Installation
Match Cooling Capacity to Your Room
Capacity affects installation as much as comfort, because a larger unit is heavier and harder to mount. An undersized unit runs constantly and still leaves the room warm, while an oversized one cools quickly and shuts off before it removes much humidity, leaving the room cold and clammy. Measure the floor area, then adjust for sun exposure, ceiling height, and how many people regularly use the space. Use the chart below as a starting point and check the stated room size for any model you consider.
ENERGY STAR publishes this general guide for sizing a room air conditioner by floor area:
| Room Size (sq ft) | Cooling Capacity (BTU/hr) |
|---|---|
| 100 to 150 | 5,000 |
| 150 to 250 | 6,000 |
| 250 to 300 | 7,000 |
| 300 to 350 | 8,000 |
| 350 to 400 | 9,000 |
| 400 to 450 | 10,000 |
| 450 to 550 | 12,000 |
| 550 to 700 | 14,000 |
| 700 to 1,000 | 18,000 |
Adjust for your room: reduce capacity by 10 percent for a heavily shaded room, increase it by 10 percent for a very sunny room, add 600 BTU for each regular occupant beyond two, and add 4,000 BTU if the unit cools a kitchen. Source: ENERGY STAR.
Measure Your Window Before You Buy
Easy installation starts with a tape measure. Record the width of the open sash and the height of the opening, then compare them with the minimum and maximum range in the listing or manual. Confirm the window style as well, since most conventional units are designed for double-hung windows that open vertically. A unit that fits within its range seals properly with the included side panels, while one that does not leaves gaps that leak cool air and let insects in.
What a Good Installation Kit Includes
A complete kit usually includes accordion side panels, foam seals, a sill bracket or support, and screws to secure the sash. Check whether tools are included, since many kits expect you to supply a screwdriver or drill. Some frames need pilot holes, which the manual will explain. Kits sold as quick or tool-light mounting systems can save time, but they still need the window to be within the listed range. Keep all the hardware together until the unit is secure and level.
Weight, Handling and Safety
Weight decides whether one person can manage the job. Compact units are easier to lift onto a sill, while larger ones call for a helper and, in some cases, an exterior support bracket. Follow the manual on tilt and support, since many units are meant to slope slightly outward so condensate drains outside. Never rely on the sash alone to hold a heavy unit, and keep children and pets away from an open window during installation.
Power and Controls After Installation
Check the listed voltage and plug requirements before installation day. Most smaller units use a standard household outlet, but the cord must reach without an extension cord, so measure the distance from the window to the nearest outlet. After mounting, simple mechanical dials are the fastest to start using, while remotes and timers make daily use easier once the unit is in place. For more on that side, see our guide to window air conditioners with remote controls.
How We Evaluate Conventional Window Air Conditioners
We compared manufacturer specifications, listing information, and buyer ratings for each model. For this guide, installation came first: a published window width and height range, an included mounting kit, a manageable weight, and standard household power. We then weighed cooling capacity against the stated room size, controls, noise where it is published, efficiency, and overall value.
Where listings disagree on a figure, such as a maximum window width, we point it out rather than pick one. Before you buy, confirm the cooling capacity, voltage and amperage, and exact window dimensions for your model in its manual, since these decide whether the unit fits your window and your outlet.
Frequently Asked Questions
Can one person install a window air conditioner?
Often, yes, with a small unit. The Midea weighs 35.3 pounds and the GE weighs 36 pounds, which most adults can lift onto a sill. Still, a second person makes it safer to hold the unit while you secure it, and larger units should always be installed by two people following the manual.
What tools do I need to install a window AC?
Most installations need only a screwdriver, a tape measure, and sometimes a drill for pilot holes. The Midea listing notes that a screwdriver is required but not included. Check the manual for your model, since some kits include brackets or screws that need a specific bit or extra hardware.
Will an easy-install unit fit a small bedroom window?
It depends on the window’s size and style, not just the unit. Compare your window with the listed range: the GE fits double-hung windows from 21.875 inches wide, slightly narrower than the Midea’s 23-inch minimum. For very narrow openings, see our guide to window air conditioners for small windows.
Do these units work in sliding windows?
The models here are conventional units for standard window frames, and the GE specifically lists double-hung windows. Sliding windows open sideways and usually need a unit or kit designed for that shape. Check the installation section of the manual before buying if your window slides horizontally, and confirm the kit can seal the opening.
Do I need a dedicated circuit for a window air conditioner?
Check the manual and the listed voltage and amperage for your model. The top picks here run on standard household power, with the GE and Frigidaire listing 115 volts. Avoid extension cords and power strips. If the outlet shares a circuit with other heavy appliances, ask a licensed electrician whether a dedicated circuit is needed.
Final Verdict
The Midea 5,000 BTU EasyCool Window Air Conditioner is our strongest overall choice for an easy install. It publishes a clear window range, includes all mounting accessories, weighs 35.3 pounds, and needs only a screwdriver, with 4.4 stars from 12,210 ratings.
If your double-hung window is on the narrow side, the GE 5,000 BTU Window Air Conditioner and its EZ Mount kit are the better fit. For a larger bedroom or small living room, the Frigidaire 8,000 BTU model adds capacity and a remote, though you should confirm its window range in the manual. Whichever you pick, measure the window first: a unit that fits its listed range is the biggest factor in a quick, secure installation.
