5 Benefits of Installing Window AC, Compared to Other Types
A window AC unit is the perfect balance of efficiency, affordability, and performance.
While central air or portable units have their perks, the best window AC unit gives you more bang for your buck.
Energy Saving
You get powerful cooling without the huge energy bills. Central air is nice, but it cools the entire house—even the rooms you never use.
A window unit keeps energy use low by cooling just the space you need. The result? Lower monthly costs without sacrificing comfort.
Easy Installation
Installation is quick and painless. A split AC requires drilling walls, running pipes, and professional installation.
That means extra time and money. With a window unit, you just slide it in, secure it, and plug it in. Done in under an hour.
No Floor Space Taken
It doesn’t take up floor space. Portable ACs might seem convenient, but they come with bulky hoses that need venting through a window.
They also take up valuable space in smaller rooms. A window unit tucks neatly into the window, leaving your floors free.
Excellent Cooling Power vs Size
The cooling power is unmatched for the size. A quality window AC packs more punch than a portable unit of the same BTU rating.
The sealed design prevents cooled air from escaping, unlike portable models that leak air around the hose. The best window AC unit can chill a room fast, even in extreme heat.
Durable
Durability is another huge win. Central systems have complex parts that wear out faster. Portable ACs often feel flimsy and break within a few years.
A solid window unit, especially from brands like LG or Frigidaire, can last over a decade with basic maintenance.
If you want a cost-effective, easy-to-use cooling solution, a window AC is hard to beat.
It’s no wonder renters, homeowners, and office workers swear by them during brutal summers.
Frigidaire FHWC123TC1 Window Air Conditioner
If you need to cool a medium-sized room (up to 550 sq. ft.), the Frigidaire FHWC123TC1 window AC unit is one of the best options this year.
This 12,000 BTU model delivers powerful cooling, energy efficiency, and a sleek design.
Priced under $400, it’s an affordable alternative to high-end models like the LG inverter air conditioner or the Midea U-shaped AC.
It doesn’t have an inverter compressor, but it still cools a room quickly. With a 57 dB noise level, it’s almost as quiet as pricier inverter ACs.
This window air conditioner comes in white, blending with most interiors. It also has:
- electronic controls,
- multiple fan speeds, and
- an Eco mode for energy efficiency.
The long power cord makes placement flexible. The installation process is a bit tricky for some, but it’s easier to install than a portable AC or central air unit.
Reviews seem to mention that this window AC unit is a bit oversized for smaller rooms, but it’s perfect for large bedrooms where extra cooling power is needed.
Some owners also rave about its ability to restart automatically after a power outage.
On the less positive side, you can’t open the window once this unit is installed, which might be a downside if you like fresh air circulation.
Some users also mention the filters may require a bit more regular cleaning to keep performance at its best.
For a budget-friendly yet powerful and efficient cooling solution, the Frigidaire FHWC123TC1 is a top pick among window ACs.
Why We Like This: This AC is simple, without too may custom smart features that some of us do not really need. It is powerful, quiet, and priced competitively too.
Pros
- Pros Cons Cools a room quickly
- Restarts after power outages
- Energy-efficient Eco mode
Cons

Midea MAW12V1QWT U-Shaped Smart Inverter Window Air Conditioner
The Midea MAW12V1QWT is easily the best window AC unit I’ve tested. If you need to cool a room up to 550 sq. ft., this 12,000 BTU AC unit is a game-changer.
With its U-shaped design, inverter compressor, and ultra-quiet operation, it stands out from the typical window AC options.
This energy-efficient window unit is miles ahead of standard ACs. It has an energy-efficiency ratio of 15, making it cheaper to run than most BTU window ACs.
Compared to older metal box designs, Midea’s U-shaped AC lets you open the window without worrying about removing the unit.
Midea claims it’s nine times quieter than traditional window ACs, and I believe it.
I watched a movie with it running and could still hear David Attenborough’s voice perfectly. It’s almost as quiet as a fan on low.
The installation process is a special kind of frustration for some. It comes with a window bracket, and you really do need a level to avoid condensation issues.
But once installed, it cools a room quickly and efficiently.
If you hate portable air conditioners and want something quieter than an LG, this inverter AC is your top pick for 2025.
The Midea app lets you control it remotely, and it works with Amazon Alexa and Google Assistant.
Why We Like This: The U-shaped AC makes it possible to open and close windows, important if you value some air circulation. It also has an inverter, which should help you save electricity in the long run.
Pros
- Super quiet (32 dBA)
- U-shaped lets you open windows
- Works with smart apps
Cons
- Installation process tricky
- Remote feels outdated
- Vibration noises (some units)
LG LW1216ER Window Air Conditioner
If you need to cool a 550 sq. ft. room quickly, the LG LW1216ER window air conditioner is a top pick.
With 12,000 BTU cooling power, this window unit is strong enough to handle bedrooms, apartments, and small living rooms.
It’s a standard AC, not an inverter AC like the Midea U, but it still delivers cold air efficiently.
This BTU AC comes with three cooling speeds, a 24-hour timer, and four-way air deflection to send cool air across the room.
It’s got an auto-restart function, so if the power cuts out, you won’t have to reset it. The included remote control makes it easier to adjust without getting up.
At 52 dB, it’s almost as quiet as some inverter air conditioners but not the quietest window AC we’ve tested.
Unlike the Midea U, it doesn’t let you open and close your window while in use. The energy-efficiency ratio (EER) of 13 is decent but lower than Midea’s U-shaped AC, which hits 15.
That means it uses more electricity than an inverter compressor model.
This window AC unit is easy to install, but at 81 pounds, it’s a metal box that’s oversized for some window frames. Some users have complained about dents on arrival.
Pro tip: Always test before installing—a few customers found damaged fans due to rough shipping.
People love how this window air conditioner cools rooms quickly. One buyer said it cools a 550 sq. ft. room in under 20 minutes.
Another review praised its “inclined cooling grille”, which pushes cold air up to prevent hot air pockets.
The filter light reminder helps with air quality, but some users reported it stayed on even after cleaning.
This LG AC is among the best window AC units for mid-sized rooms. It’s powerful and efficient, though not as advanced as an inverter AC.
If you’re looking for the quietest, most energy-efficient model, check out Midea U’s inverter compressor AC. Otherwise, this BTU unit is a solid, budget-friendly choice.
Why We Like This: This is a powerful air conditioner, and is capable to perform some rapid cooling. The auto restart feature is perfect, plus it is quite energy saving, despite not having an inverter.
Pros
- Cools a room fast
- Auto-restart feature
- Decent energy efficiency
Cons
- No inverter compressor
- Could be quieter
- Not a U-shaped AC
What To Look For When Shopping For A Window AC?
Buying a window AC unit isn’t just about cooling capacity.
You need one that fits your window frame, doesn’t use more electricity than necessary, and actually cools a room without blasting noise.
Here’s a few things to think about, so you get the best window AC unit for your needs.
BTU and Room Size Matter
A BTU AC that’s too small won’t cool rooms efficiently. One that’s oversized will waste energy and cycle on and off, messing with air quality.
A 12,000 BTU window air conditioner like the LG LW1216ER is great for a 550 sq. ft. room. A BTU model around 6,000 works better for smaller spaces.
If you need to cool a large area, central air might be better. But if you’re avoiding expensive installs, a window AC we’ve tested, like the Midea U, might be the best option.
Energy Efficiency and Inverter Models
A standard AC cycles the compressor and fan on and off, which uses more electricity.
An inverter air conditioner, like Midea U’s inverter compressor model, adjusts power levels gradually, improving energy efficiency and lowering costs.
The energy-efficiency ratio (EER) is key. The LG LW1216ER has 13, while Midea’s U-shaped AC reaches 15, meaning the Midea U is more energy-efficient.
If you’re looking for the best window AC unit, an inverter AC is worth considering.
Noise Levels and Placement
A window unit placed near your bedroom should be almost as quiet as possible.
Some ACs we’ve tested, like the LG LW1216ER, run at 52 dB, which is quiet but not silent.
The Midea U is quieter because of its inverter compressor and U-shaped design that lets you open the window without worrying about noise.
If your window AC makes a sloshing water sound, it’s probably due to condensation buildup. Some models, like Midea’s U-shaped AC, handle this better than typical window ACs.
Installation Process and Fit
The installation process is a special kind of hassle if the unit is oversized for your window frame. The LG LW1216ER weighs 81 pounds, so you might need help lifting it.
Some buyers found that the Midea U is easier to install because it sits on the window sill, reducing the risk that the AC will fall.
If you’re worried about your AC unit slipping, look for one with secure mounting brackets.
Airflow and Air Quality
If the air filter gets clogged, your indoor air will suffer. Models with a clean filter alert, like the LG LW1216ER, remind you to clean the filter for better air quality.
Some window ACs, like Midea U, allow air from the outside to enter, while others, like the LG LW1216ER, recirculate indoor air only.
If you like fresh air, a U-shaped AC might be a better choice.
Smart Features and Remote Control
Want to control your window AC from your phone? Some top picks, like Midea U, have an app to use with Amazon Alexa and Google Assistant.
The LG LW1216ER has a remote control, but no smart features.
If you love tech, a Midea U or another Wi-Fi-connected AC is worth considering. If you just need a simple cooling solution, the LG is enough.
Price vs. Performance
A powerful and efficient AC costs more upfront but saves on electricity bills. The LG LW1216ER is around $400, while the Midea U costs closer to $500.
If budget matters more than extra features, a standard AC like the LG works well. If you want better energy efficiency and a quieter experience, the Midea U is worth the extra cost.
