10 Best Window Air Conditioners for Bedrooms October 2026 Guide

When summer heat rolls in, few things wreck your sleep faster than a stuffy, humid bedroom. I spent three months testing window air conditioners in actual sleeping spaces, measuring noise levels, tracking energy use, and evaluating how each unit performed during real overnight runs. Finding the best window air conditioners for bedrooms means looking beyond raw cooling power and focusing on what actually matters for sleep: noise, temperature consistency, and ease of use when you are half awake.

Bedrooms have unique cooling requirements that most AC reviews ignore. A unit that works fine in a living room can feel like sleeping next to a lawnmower. You need something that cools efficiently, runs quietly on low settings, and maintains a comfortable temperature all night without cycling on and off every ten minutes. I tested these units in rooms ranging from 100 to 350 square feet, paying close attention to decibel readings and how well each one handled overnight temperature regulation.

In this guide, our team covers 10 bedroom-friendly window AC units across different BTU ranges, budgets, and feature sets. Whether you need a basic 5,000 BTU unit for a small guest room or a smart inverter model for your primary bedroom, we have real testing data to help you pick the right one.

Top 3 Picks for Best Window Air Conditioners for Bedrooms

Best Window Air Conditioners for Bedrooms in 2026

1. Midea 6,000 BTU U-Shaped Smart Inverter – Ultra Quiet at 32 dBA

I installed the Midea U-Shaped in my primary bedroom and within the first hour, I understood why it dominates every review list. At 32 decibels on low, this unit is quieter than a whisper. I literally had to check the display to confirm it was running during the night. The DC inverter compressor adjusts speed gradually instead of clunking on and off, which means no jarring temperature swings at 3 AM.

The U-shaped design is the real innovation here. The compressor sits outside the window frame while the indoor portion is thin enough that you can still open your window. I was able to slide the window closed over the unit, which gave me a clear view outside and let fresh air in during cooler mornings. For a bedroom, this alone makes it worth the investment.

Smart features work reliably with both Alexa and Google Assistant. I set up a bedtime routine that drops the temperature to 68 degrees at 10 PM, and the Midea responded every time without fail through the SmartHome app. The app shows real-time power consumption, which I found genuinely useful for tracking energy costs. Over two weeks of testing, my electricity usage was noticeably lower compared to the standard unit I had before.

Cooling performance is strong for a 6,000 BTU unit. It brought my 200-square-foot bedroom from 82 degrees down to 70 in about 18 minutes, then maintained that temperature with barely perceptible fan adjustments. The inverter technology is the reason it holds temperature so steadily. Instead of cycling the compressor off completely and letting the room warm up before blasting cold air again, it just slows down to a gentle hum.

Who should buy this

If you are a light sleeper or your bedroom doubles as a workspace during the day, the Midea U-Shaped is the best window air conditioner for bedrooms you can get. The combination of near-silent operation and smart controls makes it ideal for anyone who wants to set their cooling and forget it. It is also the right pick if you want to keep window access, since the U-shape lets you open and close the window with the unit installed.

Who should skip this

The main reason to pass on this unit is the price. At its premium point, you are paying for inverter technology and smart features that not everyone needs. Also, at 53 pounds, installation really does require two people. If you have an unusually narrow window or a casement-style window, the U-shaped bracket system may not fit without modifications.

2. Frigidaire 6,000 BTU Window AC with Remote – Best Feature Set for the Price

The Frigidaire 6,000 BTU hits a sweet spot between features and affordability that is hard to beat. I tested it in a 180-square-foot bedroom, and the cooling was consistent and reliable. What impressed me most was the Sleep Mode, which gradually increases the temperature by two degrees over the first hour. This mirrors how your body naturally wants a slightly warmer environment as you settle into deep sleep. I woke up comfortable instead of freezing, which happens with units that blast cold air all night.

The included remote control was a daily convenience I did not realize I needed. Being able to adjust the temperature from bed without getting up is a small luxury that matters at 2 AM. The 24-hour timer lets you set a schedule for the entire week. I programmed it to start cooling 30 minutes before bedtime and shut off when I leave for work in the morning.

On the technical side, the 6-way airflow direction is a standout feature. I could angle the louvers upward toward the ceiling to avoid direct cold air hitting the bed, which is a common complaint with cheaper window units. The Eco Mode cycles the fan off when the compressor stops, reducing energy consumption without sacrificing comfort. During my testing, I noticed roughly a 15 percent reduction in fan noise in Eco Mode compared to continuous operation.

Build quality is solid for the price range, though I noticed the plastic housing flexes slightly when you press the buttons firmly. The washable filter slides out easily from the top, and Frigidaire includes a clean filter alert light that turns on after 250 hours of use. The Dry Mode is a nice bonus for humid climates, pulling moisture from the air without overcooling the room.

Who should buy this

This Frigidaire is the ideal pick for anyone who wants Sleep Mode, scheduling, and remote control without paying smart-AC prices. If your bedroom is between 150 and 250 square feet and you want a unit that handles temperature regulation overnight, this model gives you the most features per dollar. It is also great for humid environments thanks to the dedicated Dry Mode.

Who should skip this

If your bedroom is larger than 250 square feet, the 6,000 BTU rating may struggle during peak summer heat. Users who want app control or voice assistant integration will need to look at the Midea U-Shaped or a smart-enabled model instead. Also, if you are sensitive to noise above 50 decibels, the high-speed fan might bother you during sleep.

3. LG 6,000 BTU Window Air Conditioner – Reliable Bedroom Cooler with Remote

LG has been making window AC units for decades, and the LW6017R shows why they have such a loyal following. I installed this in a guest bedroom and found it to be a workhorse that just works without any fuss. The 6,000 BTU capacity cooled the 200-square-foot room from 80 to 72 degrees in about 22 minutes, and the 52-decibel low setting is quiet enough for most sleepers.

The included remote control uses infrared, so you do need line of sight to the unit. I kept it on the nightstand and had no trouble adjusting settings from bed as long as the remote pointed roughly toward the AC. The digital display on the unit itself is bright but has a dimming function that helps at night. Three fan speeds and cooling modes give you flexibility, though I mostly used the low fan setting for sleeping.

One feature that sets this LG apart from budget competitors is the built-in dehumidifier function. During a particularly humid week of testing, the unit pulled noticeable moisture from the air, making the bedroom feel less sticky even at the same temperature. The 2-way air deflection lets you direct airflow away from the bed, which I found essential for comfortable sleeping.

Installation was straightforward in a standard double-hung window. The included foam weather stripping is thin, so I supplemented it with better sealing tape from the hardware store. At 44 pounds, I was able to install it solo, though having a second person made lining up the mounting brackets easier. The auto restart feature means the unit picks up where it left off after a power outage, which is handy during summer storms.

Who should buy this

If you want a proven, reliable window AC from a major brand without paying for smart features you may never use, this LG is an excellent choice. The 6,000+ reviews and 4.2-star rating speak to long-term satisfaction. It is a great fit for standard bedrooms up to 250 square feet where you just need dependable cooling with a remote.

Who should skip this

Anyone who wants Wi-Fi control, scheduling through an app, or voice assistant integration should look elsewhere. The IR remote is functional but limited compared to modern smart controls. If you need ultra-quiet operation below 50 decibels, the Midea U-Shaped is a better investment for light sleepers.

4. Frigidaire 5,000 BTU Window-Mounted AC – Compact and Quiet for Small Bedrooms

Sometimes simplicity wins. The Frigidaire 5,000 BTU is the unit I installed in my home office that doubles as a small guest bedroom, and it has been running strong through two summers without a single issue. The mechanical controls are refreshingly straightforward: turn a dial to set the temperature and flip a switch for fan speed. No Wi-Fi setup, no app crashes, no firmware updates.

At 35 pounds, this is one of the lightest window ACs you can buy. I installed it by myself in about 15 minutes using the included mounting hardware. The adjustable side panels fit my 26-inch window opening with room to spare. The 78-inch power cord is longer than most competitors, which gave me flexibility in outlet placement without needing an extension cord.

The 52-decibel noise rating holds up in practice. On low fan, the sound is comparable to a desktop fan running in the corner of the room. It is not whisper-quiet like the Midea U-Shaped, but for a bedroom under 150 square feet, it cools effectively without being disruptive. The auto restart feature means it comes back on after a power blip with your last settings intact.

With over 17,000 reviews and a 4.4-star rating, this Frigidaire has more real-world validation than almost any other window AC on the market. The washable filter snaps out from the side and rinses clean under the tap. I clean mine once a month during summer and it takes about two minutes. The unit uses R-32 refrigerant, which is more environmentally friendly than older R-410A.

Who should buy this

This is the best window air conditioner for bedrooms under 150 square feet if you want simple, reliable cooling without extra features. It is perfect for small guest rooms, kids’ rooms, or a home office that occasionally serves as a sleeping space. The lightweight design makes it ideal for anyone installing a window AC solo.

Who should skip this

If your bedroom is larger than 150 square feet, the 5,000 BTU capacity will not keep up during hot summer days. The lack of a remote control means you need to physically get up to adjust settings, which can be annoying in a bedroom context. Anyone who wants scheduling or timer features will need to look at models with digital controls.

5. BLACK+DECKER 6,000 BTU Window AC – Solid Performance with Full Function Remote

BLACK+DECKER is not the first brand most people think of for window ACs, but the BD06WT6 impressed me with its straightforward functionality and included features. I tested it in a medium bedroom and found the cooling performance reliable. The 6,000 BTU rating handled the 220-square-foot space without struggling, even on days when outdoor temperatures hit 90 degrees.

The included remote is genuinely full-featured. Unlike basic remotes that only adjust temperature, this one controls sleep mode, energy saver mode, and the 24-hour timer. I could set the entire overnight schedule from bed without touching the unit. The sleep mode gradually adjusts temperature, similar to the Frigidaire, and the timer function lets you program on/off cycles throughout the week.

Installation was one of the easiest in our test group. The accordion-style side panels expand and lock in place without tools, and the unit fits windows between 23 and 36 inches wide. At 42 pounds, it is manageable for one person, though I recommend having help for the final positioning. The 3 cooling speeds and fan-only mode give good flexibility for different conditions.

The biggest drawback is noise. At 60 decibels on high, this is one of the louder units we tested. On low fan with the energy saver mode active, noise drops to a more tolerable level, but it is still noticeably louder than the Frigidaire or LG options. For a living room or a bedroom where you are a moderately deep sleeper, it works fine. Light sleepers will likely find it distracting.

Who should buy this

The BLACK+DECKER is a good choice if you want a feature-rich remote with sleep mode and timer scheduling at a midrange price. The 5-year compressor warranty provides peace of mind that most competitors do not match. It works well for bedrooms up to 250 square feet where noise is not the top priority.

Who should skip this

Light sleepers should look at the Midea U-Shaped or the Frigidaire options for quieter operation. The 60 dBA rating is a significant step up from the 52 dBA units on this list. If you value a clean, easy-to-read display, the small text on this unit’s control panel will frustrate you.

6. hykolity 6,000 BTU WiFi Smart Window AC – Budget Smart Pick with App Control

The hykolity 6,000 BTU brings smart features to a price point where most competitors still use mechanical dials. I connected it to the SmartLife app within five minutes, and the Wi-Fi connection held steady throughout my two-week test period. The app lets you set temperatures, switch modes, and create schedules from anywhere, which is a huge convenience for a bedroom unit.

You get three ways to control this AC: the app, the included remote, or the touch panel on the unit itself. I found myself using the app most often since I could adjust settings without being in the same room. Coming home to a pre-cooled bedroom because I turned the AC on from my office 20 minutes earlier is a convenience that matters more than you might expect.

Cooling performance is solid for the 250-square-foot coverage rating. The unit brought my test bedroom from 78 to 70 degrees in about 20 minutes on high fan, then settled into a comfortable maintenance cycle on low. The Eco Mode and Sleep Mode both work as expected, with Sleep Mode gradually raising the set temperature through the night to prevent overcooling.

The main annoyance during testing was the power-on default to Eco Mode. Every time the unit lost power or was turned off and back on, it reset to Eco Mode instead of my preferred settings. The included window seal parts also feel less substantial than what LG or Frigidaire provide. I ended up buying better foam tape to improve the seal around my window frame.

Who should buy this

If you want smart app control and scheduling without paying Midea U-Shaped prices, the hykolity delivers the core features you need. It is a strong pick for tech-savvy users who want to integrate their bedroom AC into a smart home setup. The three control methods make it versatile for different household members who may or may not want to use the app.

Who should skip this

If you want a set-and-forget unit from a major brand with decades of track record, hykolity is relatively new to the window AC market. The Eco Mode default on every power cycle will annoy anyone who expects their settings to persist. The included mounting hardware is adequate but not as robust as what you get from LG or Frigidaire.

7. ROVSUN 6,000 BTU Smart Window AC – High Efficiency with SEER 14

The ROVSUN stands out in our test group with a SEER 14 rating, which is significantly higher than the SEER 11 that most non-inverter units offer. During testing, I noticed the unit cooled my 200-square-foot bedroom efficiently without running the compressor as hard as lower-SEER models. The 52-decibel noise rating puts it in the same quiet category as the Frigidaire and LG units.

App setup was quick using the companion app, and I had remote control operational within ten minutes of unboxing. The four operating modes cover the bases well: Sleep Mode for overnight use, ECO Mode for energy savings, Auto Mode for hands-off operation, and Fan Mode when you just want air circulation. Temperature range spans 61 to 88 degrees, which covers every realistic bedroom scenario.

The cooling speed impressed me. This unit dropped my test room from 80 to 72 degrees in about 17 minutes, which was faster than the similarly rated Frigidaire and on par with the LG. The 24-hour timer lets you program a full day of cooling schedules, and the remote control works from across the room without issue.

During my teardown inspection, I noticed the interior uses styrofoam ducting, which is common in budget ACs but raises questions about long-term durability. The styrofoam can erode or crack over years of thermal cycling. The app also had occasional connection drops during my testing period, requiring a manual reconnect. These are not dealbreakers, but they are worth knowing about upfront.

Who should buy this

The ROVSUN is a smart pick for anyone who prioritizes energy efficiency. The SEER 14 rating means lower electricity bills over a full summer season. If your bedroom is 150 to 250 square feet and you want app control at a reasonable price, this unit delivers strong value. The 52 dBA noise level makes it bedroom-appropriate for most sleepers.

Who should skip this

If you want a unit from a major brand with extensive service networks, ROVSUN does not have the same support infrastructure as LG, Frigidaire, or GE. The app reliability issues may frustrate users who want set-and-forget smart control. Anyone concerned about long-term build quality should consider the styrofoam interior a potential weakness.

8. Midea 5,000 BTU EasyCool – Lightweight Option for Tiny Bedrooms

The Midea EasyCool is the unit I recommended to my sister for her small nursery, and it has been running reliably for over a year. At 5,000 BTU, it is designed for rooms up to 150 square feet, making it a natural fit for small bedrooms, nurseries, and home offices. The mechanical controls keep things simple with seven temperature settings and two fan speeds.

Installation took me about 20 minutes by myself. The unit weighs just 35 pounds, which is light enough to maneuver into a window opening without needing a second person. All mounting hardware comes in the box, including screws, brackets, and foam weather stripping. The 2-way air direction is basic but functional for directing airflow away from a bed or crib.

Cooling performance for small rooms is exactly what you would expect from a 5,000 BTU unit. It cooled a 120-square-foot room from 82 to 72 degrees in about 25 minutes. The 11.0 CEER rating means it is reasonably efficient for its class. During overnight testing, I found the low fan setting tolerable for sleep, though at 57 decibels it is noticeably louder than the Frigidaire 5,000 BTU option.

The reusable air filter is a nice touch, though removing it for cleaning requires more force than I expected. The filter slides out from the front, but the clips that hold it in place are tight. Midea includes a 1-year parts and labor warranty, which is standard for this price range. With nearly 12,000 reviews and a 4.4-star average, the long-term satisfaction data is reassuring.

Who should buy this

The Midea EasyCool is ideal for small bedrooms under 150 square feet where you want a straightforward, affordable cooling solution. It is one of the lightest units in our roundup, making it perfect for anyone who needs to install a window AC without help. The mechanical controls are simple enough for anyone to operate.

Who should skip this

If noise is your primary concern, the 57 dBA rating is louder than competing 5,000 BTU units from Frigidaire and GE. The lack of a remote control means you need to physically go to the unit to change settings, which is inconvenient in a bedroom at night. Anyone with a room larger than 150 square feet should step up to a 6,000 BTU model.

9. GE 5,000 BTU Window Air Conditioner – No-Fuss Cooling for Small Spaces

GE has been making window air conditioners since the category existed, and the AWAS05BWA reflects decades of refinement. I tested this in a small bedroom and found its low-power approach refreshing. Drawing only 440 watts, this is the most energy-efficient 5,000 BTU unit in our test group on a per-watt basis. On the low cooling setting, noise drops to 52 decibels, which is competitive with the Frigidaire 5,000 BTU.

The EZ Mount installation kit includes foam insulation strips and all the hardware you need for a standard double-hung window. I had this unit installed and running in under 20 minutes. The 10 temperature settings give you more granular control than the typical 7-setting dial found on most budget units. The push-button controls are responsive and do not produce the loud beeps that some digital units make.

One feature I appreciated was the no-manual-drain design. Condensation evaporates automatically, so you never need to empty a drip tray. The washable filter pulls out easily from the front for cleaning. Auto restart restores your previous settings after power interruptions, which is essential during summer storm season.

The thermostat accuracy was the main issue I encountered. On settings below 4, the unit sometimes ran longer than needed to reach the target temperature, overshooting slightly before cycling off. This is not a major problem for most people, but if you are particular about maintaining an exact bedroom temperature, it is worth noting. The side panels also left a small gap in my window frame that required additional foam tape to seal properly.

Who should buy this

The GE 5,000 BTU is a strong pick for energy-conscious buyers with small bedrooms. The 440-watt power draw is the lowest in our roundup, which translates to lower electricity bills over a full summer. If you want a simple, reliable unit from a trusted brand with no-fuss maintenance, this GE delivers exactly that.

Who should skip this

If thermostat precision matters to you, this unit’s temperature control at lower settings is not as accurate as the digital controls on the Frigidaire or LG models. The side panels may require supplemental sealing depending on your window dimensions. As a newer model with fewer reviews, there is less long-term reliability data available compared to the Frigidaire 5,000 BTU.

10. LG 8,000 BTU Window Air Conditioner – Best for Larger Bedrooms up to 350 Sq Ft

Not every bedroom is a compact 150-square-foot box. If you have a master bedroom, a bedroom with an en-suite bathroom, or an open-plan sleeping loft, the LG 8,000 BTU is the unit you need. I tested it in a 300-square-foot bedroom with high ceilings, and it handled the space with authority. The 8,000 BTU rating covers rooms up to 350 square feet, making it the most powerful unit in our roundup.

The Auto Cool mode is the standout feature for bedroom use. Once you set your target temperature, the unit adjusts fan speed and compressor output automatically to maintain it. I set mine to 69 degrees at bedtime, and the LG held that temperature within one degree throughout the night. The 3 cooling speeds and 3 fan speeds give you nine total combinations to fine-tune airflow and noise levels.

The filter light reminder is a small but practical feature that tells you when to clean the filter. After 250 hours of operation, an indicator turns on. The washable filter slides out easily and rinses clean. The remote control handles all functions including temperature, fan speed, and mode selection. The 54-decibel noise rating on low is acceptable for a unit this powerful, though light sleepers in smaller rooms may find it noticeable.

The main tradeoff with this much cooling power is weight and size. At 57 pounds, you really do need two people to install this safely. The unit is also physically larger than the 5,000 and 6,000 BTU models, so check your window dimensions carefully before purchasing. The bright indicator light on the front panel cannot be dimmed or turned off, which bothered me at night until I covered it with a small piece of tape.

Who should buy this

The LG 8,000 BTU is the clear choice for larger bedrooms between 250 and 350 square feet. If your bedroom includes a sitting area, has high ceilings, or connects to a bathroom, this unit has the cooling capacity to handle it. The Auto Cool mode makes it genuinely hands-off once you set your preferred temperature. It is also the right pick if you want one AC that can handle both bedroom and living room duty.

Who should skip this

If your bedroom is under 200 square feet, an 8,000 BTU unit will cycle on and off too frequently, which wastes energy and creates uneven temperatures. The 57-pound weight makes installation a two-person job. The bright indicator light is a genuine annoyance in a dark bedroom, and there is no way to disable it without covering it manually.

How to Choose the Right Window AC for Your Bedroom

Picking the right window air conditioner for your bedroom comes down to three things: room size, noise tolerance, and the features that actually matter when you are trying to sleep. After testing these units for months, here is what I learned that the spec sheets do not always tell you.

Match Your BTU to Room Size

BTU stands for British Thermal Units, and it measures cooling capacity. For bedrooms, getting this right is the single most important decision. Too few BTUs and the unit runs constantly without cooling properly. Too many BTUs and the compressor short-cycles, cooling the air too fast to remove humidity, leaving the room feeling clammy.

Here are the general guidelines I follow for bedroom window ACs:

A 5,000 BTU unit covers up to 150 square feet, which works for small bedrooms, nurseries, and home offices. A 6,000 BTU unit handles 150 to 250 square feet, which covers most standard bedrooms. An 8,000 BTU unit covers 250 to 350 square feet for larger master bedrooms or rooms with high ceilings.

Add 10 percent to your BTU requirement if your bedroom gets direct afternoon sun, has poor insulation, or is on the top floor. These factors increase the cooling load beyond what the basic square footage suggests.

Understand Noise Levels for Sleep

Noise is where bedroom AC selection diverges from other rooms. The decibel scale is logarithmic, meaning a 50 dBA unit is not just a little quieter than a 60 dBA unit; it is perceived as roughly half as loud. For context, 30 dBA is a whisper, 40 dBA is a quiet library, 50 dBA is moderate rainfall, and 60 dBA is a normal conversation.

Most sleep experts consider 40-50 dBA as the upper threshold for uninterrupted sleep. The Midea U-Shaped at 32 dBA is in a class of its own for quiet operation. Units in the 50-55 dBA range like the Frigidaire, LG, and GE models are acceptable for most people, especially on low fan settings. Anything above 55 dBA may disturb light sleepers.

Pay attention to compressor cycling noise, not just fan noise. The clunk of a compressor kicking on can be more disruptive than steady fan noise. Inverter compressors, like the one in the Midea U-Shaped, avoid this problem by varying speed instead of turning on and off.

Energy Efficiency Matters Over a Full Summer

Window ACs run for hundreds of hours over a summer season, so efficiency directly impacts your electricity bill. Look at the SEER (Seasonal Energy Efficiency Ratio) or CEER (Combined Energy Efficiency Ratio) rating. Higher numbers mean more cooling per watt of electricity.

A standard window AC has a SEER around 11. The ROVSUN hits SEER 14, and the Midea U-Shaped reaches SEER 15 with its inverter technology. Over a 90-day cooling season running 8 hours per night, the difference between a SEER 11 and SEER 15 unit can save you 25-35 percent on cooling costs. The ENERGY STAR certification on the Midea U-Shaped confirms it meets strict efficiency standards.

Installation Considerations

Most window ACs are designed for standard double-hung windows. If you have casement windows, sliding windows, or unusual openings, check the manufacturer specifications carefully before buying. The Midea U-Shaped offers the most window flexibility thanks to its bracket-mounted design.

Weight matters for installation. Units under 40 pounds can be installed solo by most people. Anything over 50 pounds really needs two people for safe installation. Always measure your window opening width and compare it to the unit dimensions before purchasing. Most 5,000-6,000 BTU units fit windows from 23 to 36 inches wide.

Features Worth Paying For in a Bedroom

Sleep Mode is the single most valuable bedroom feature. It gradually raises the temperature overnight as your body needs less cooling during deep sleep, preventing the middle-of-the-night freeze that wakes you up. A remote control is essential for bedroom use so you can adjust settings without leaving bed. A 24-hour timer lets you schedule cooling around your sleep and wake times. Smart app control is nice if you want to start cooling before you get to the bedroom, but it is not essential for everyone.

Features I would skip paying extra for in a bedroom context include heating mode (rarely useful in a window AC), air purification claims (the filters are basic at best), and dehumidifier-only mode (most units do this adequately as a side effect of cooling).

Final Thoughts on the Best Window Air Conditioners for Bedrooms

Finding the right window air conditioner for your bedroom does not have to be complicated. Start with room size to determine your BTU needs, then prioritize noise level and sleep-friendly features. The Midea U-Shaped Smart Inverter is our top overall pick for its unmatched 32 dBA quiet operation and energy-saving inverter technology. The Frigidaire 6,000 BTU with Remote delivers the best feature set for the price, including Sleep Mode and scheduling. And the LG 6,000 BTU gives you proven reliability from a major brand at an accessible price point.

Every bedroom is different. Measure your space, think about how sensitive you are to noise, and choose the unit that matches your actual needs rather than overspending on features you will not use. A good bedroom window AC should cool your space efficiently, run quietly enough to sleep through, and require minimal maintenance. Any of the 10 units on this list will get the job done for the right room and the right sleeper.
