Our Verdict
If you need a quiet and energy-efficient window air conditioner for your apartment, the Midea U-Shaped MAW08V1QWT operates at a superior 48.7 decibels. This reduced noise level, combined with its Energy Efficiency Ratio (EER) of 15, makes it a good match if you value tranquility and sustainability. It also excels with its Energy Efficiency Ratio (EER) of 15 and a BTU cooling rating of 8,000.
This model also maintains a comfortable temperature in rooms up to 350 square feet. Its U-shaped design allows for quieter operation and more efficient cooling, making it perfect for small apartments or bedrooms where noise is a concern. Note that the MAW08V1QWT comes with a notably short 6-inch cord, which may require the use of an extension cord for optimal placement and installation if your designated window isn’t near a power outlet.
When compared to its sibling, the MAW08V1QWT stands out as the better value if you need efficient cooling for smaller spaces. It also has a slightly lower noise level if you need the quietest AC possible for your noise-sensitive pets or children. Remember that the MAW12V1QWT offers a higher BTU output, which may be more suitable for living in a larger apartment or home.
If you value a balance between efficient performance and a quiet atmosphere, the MAW08V1QWT is a reliable window AC to consider. Despite its short power cord and lower BTU cooling rating versus other models, it’s an outstanding investment if you need effective cooling without the disruptions of a noisy appliance.

Our Verdict
The Midea U-shaped MAW12V1QWT is an excellent window air conditioner that tackles larger spaces efficiently with a cooling capacity of 12,000 BTU. Coupled with an airflow rate of 277 CFM, this unit is designed for spaces up to 550 square feet. Though expensive, it’s a solid AC unit if you’re a homeowner or renter in a larger apartment who needs effective climate control. It also boasts an impressive Energy Efficiency Ratio (EER) of 15, indicating its energy-efficient and cost-effective operation.
The MAW12V1QWT maintains a comfortable living environment with a noise level of 50.6 decibels, making it reasonably quiet for its size and power. It’s equipped with modern features such as Wi-Fi connectivity, allowing for control via mobile apps or voice assistants. It is ideal if you’re tech-savvy or appreciate convenience in managing your home devices. The Midea U-shaped MAW12V1QWT also features a 6.5-foot power cord, providing ample length for flexible installation options without the need for an extension cord.
If you compare it to the smaller MAW08V1QWT model, the MAW12V1QWT offers more cooling power, making it suitable for bigger rooms where the MAW08V1QWT cannot effectively cool. The MAW08V1QWT is slightly quieter and is a better value if you need less cooling capacity for a smaller room or apartment, but it has a short power cord, so you may need to use an extension cord with it.
Despite its high price tag, this reliable AC unit will keep larger spaces cool without disrupting the peace in your home. Its combination of high BTU output, efficiency, and user-friendly technology ensures that it performs effectively and conveniently in your space.

Our Verdict
If you want a simple solution to cooling your room or small apartment, the Windmill AC 8000 is a convenient unit that’s easy to install. It comes equipped with a 6 ft. long power cord, providing ample flexibility for installation without the immediate need for an extension cord. With a cooling capacity of 8,000 BTU and an airflow rate of 200 CFM, it’s tailored for spaces up to 350 square feet—ideal for small apartments or individual rooms. The unit’s Wi-Fi connectivity adds convenience, allowing you to adjust settings from your smartphone.
When setting up a workspace or home office where a quiet atmosphere is crucial, the Windmill AC 8000 operates at 52.5 decibels. While it’s not the quietest, it balances noise level and cooling efficiency, ensuring you can work or relax without too much background noise. Its energy efficiency rating of 11.7, though not the highest, still supports reasonable power consumption.
Compared to the Midea U-Shaped MAW08V1QWT, the Midea and the Windmill AC 8000 share the same 8,000 BTU capacity and will cool the same sized area. However, the Windmill is the better value and has a longer 6-foot power cord, offering more flexibility in installation without needing an extension cord, unlike the shorter-corded Midea. The Midea boasts a higher EER and quieter operation if you need the quietest unit possible.
If you appreciate smart features and need an AC that integrates seamlessly into a connected home, the Windmill AC 8000 is worth considering. Its features cater well to those needing efficient cooling and modern conveniences, though it may fall short if you have a larger space to cool or need the utmost energy savings or ultra-quiet operation.

It can cool areas up to 450 square feet, making it well-suited for medium-sized living rooms or large bedrooms. This model caters especially to homeowners or renters looking for straightforward functionality with smart connectivity, evidenced by its mobile app integration.
If you want to maintain a comfortable temperature without the complexities of more advanced systems, this unit’s straightforward three cooling settings and three fan speeds provide a user-friendly experience.

While not the highest, its energy efficiency ratio (EER) of 5 supports moderate energy consumption for its size.
When compared to the Midea U-Shaped MAW12V1QWT, the Hisense model holds a competitive edge with its lower cost despite the Midea’s higher EER and quieter operation.

The Midea will cool large spaces more effectively and efficiently, making it better suited if you’re concerned about energy consumption and live with noise-sensitive pets or roommates.
If you value an air conditioner that combines affordability with essential features, the Hisense 10000-BTU Window AC is a reliable unit to consider. Despite its lower EER and noisier operation than other units, it offers enough power to handle moderately sized spaces with the added convenience of smart controls, making it an excellent unit if you’re a budget-conscious person who still needs a unit that can get the job done and keep your home cool and comfortable.

Which Criteria Matters for Testing Best Window Air Conditioners?
By focusing on these criteria (1 required), anyone can quickly and easily compare these air conditioners and how they’ll perform. This helps you make an informed decision and purchase an air conditioner that has an operating noise of less than 55 dB.
| CRITERIA | RANGE | REQUIRED | DEFINITION |
|---|---|---|---|
| Operating Noise | < 55 dB | Yes | How much noise the unit makes while it is under normal operation. |
Our Trusted Data Sources
We looked at 60+ air conditioner reviewers and found that 15 are trustworthy (60%+ Trust Rating). The three we have listed below are our most trusted for air conditioners.
- Austin Palmer – TechGearLab, MuckRack
- Daniel Jackson – Your Best Digs
- Derek Hales – Modern Castle, LinkedIn
Interested in a comprehensive analysis of our data sources? We’ve got you covered. Below, you’ll find a detailed list of every air conditioner review website we’ve identified, organized by their respective Trust Ratings from highest to lowest. But we didn’t stop there. We’ve meticulously reviewed each publication and verified the data by checking whether the authors have bio links to MuckRack or LinkedIn. We’re committed to not only checking the facts but ensuring their veracity.
Air Conditioner Test Data & Results
1. Operating Noise (dB)
All air conditioners make noise, this is a fact. Generally speaking, the more airflow an A/C unit has, the louder it’s going to be, and (logically) the more capable it is of cooling larger spaces (or smaller spaces more quickly.) Quieter A/C units are less disruptive and are often more attractive if you like a more peaceful home, but if your cooling needs are very high, be ready to see higher noise levels.
It’s for this reason we recommend an operating noise level around 55 dB or less. This puts it below the noise of a typical conversation and allows the sound to fade away into being background noise or even white noise. Higher volumes can be distracting, especially if you’re very sensitive to droningsounds.
Operating Noise
< 55 dB
Acceptable range of performance
Definition: How much noise the unit makes while it is under normal operation.
Units of Measurement: dB (decibels)
Tools to Measure: Sound pressure level meter or decibel meter
Why It’s Important:
Loud units are annoying and disruptive, and quiet units fade into the background more easily.
Operating Noise (dB; lower is better; 0 = No Data)
Best Window Air Conditioners: Mistakes To Avoid
- Ignoring BTU Rating: Buying a window air conditioner without considering its BTU rating can lead to inadequate cooling or inefficiency. It’s important to choose a unit with a BTU rating that matches your room size. An underrated unit won’t cool effectively, while an overrated one will cycle too often, wasting energy.
- Neglecting Room Size: Underestimating the size of the room can result in an underperforming air conditioner, while overestimating can mean spending more than necessary. Measure your room’s dimensions and compare them to the manufacturer’s recommendations to ensure proper cooling capacity.
- Overlooking Energy Efficiency: Ignoring the energy efficiency rating of a window air conditioner can lead to higher electricity bills. Look for units with a high EER (Energy Efficiency Ratio) or ENERGY STAR certification to save money over time and reduce environmental impact.
- Not Checking Noise Levels: Overlooking the noise level of a window air conditioner can lead to a disruptive environment. Check the decibel (dB) rating to ensure the noise level is acceptable for your space, especially if it will be used in a bedroom or office.
