1. Frigidaire FFRA0511R1:

This is one of the smallest air conditioners that you can buy for a very affordable price of just $129. It is perfect for cooling rooms with sizes up to 150sf, meaning just about perfect for a smaller room with space issues. This air conditioner is rated at 5000 BTU’s, meaning that it’s incredibly efficient. It is also simple to use as it has just two knobs to adjust everything.

All things considered, it is perfect for cooling single rooms with limited spaces. Also, all the mounting hardware is provided right into the package, making things even more convenient. It takes about 20 minutes to install for someone experienced so you can have this sucker hummin’ along in no time at all.


Pros: Lightweight, easy to set up window installation, very quiet despite the size, requires only an 115v electrical outlet.
Cons: Small output as expected, so it’s best for smaller rooms, and no remote to control the unit.

2. Frigidaire FRA052XT7:

It is also a small window mounted air conditioner unit that is also perfect for rooms measuring up to 150 feet. It is, however, priced a bit higher than the Frigidaire FFRA0511R1.The reason for that is this is one of the most efficient window-mounted air conditioners that you can get. It uses very less power, and its cooling potential is undoubtedly awesome.

The best part, however, is that it has a bacterial mesh built into the unit which helps in delivering clean and pollutant free inside the rooms. Also, like the previous model, all the mounting hardware is built right into the box, so it’s very to install. It has an output rating of 5000BTU’s which is excellent for its size. It is also one of the best Window Air Conditioners that you can buy for a reasonable price.


Pros: Compact, lightweight, incredibly energy efficient, bacterial filter built in, two-directional air throw adjustments.
Cons: Slightly expensive for that it offers, small output not ideal for medium or large rooms, no remote, manual controls.

3. Frigidaire FRA054XT7:

I don’t know why Frigidaire insists on having such complicated names for their air conditioners, but the FRA054XT7 is one of the higher end offerings from them for a compact air conditioner. It is priced at $209, and for that, you get all the features and quirks that you would generally expect it to have.

For starters, it has an output of 5000BTU’s which may seem less for a medium sized room, but it works perfectly for smaller rooms with up to 200sq feet of space. Its biggest advantage is that it has remote controls for easy adjustments of temperatures and has a low voltage start feature.


Pros: Remote adjustments, energy efficient, can be adjusted for directional airflow, lightweight, doesn’t require a lot of power.
Cons: Expensive for a small window mounted air conditioner, isn’t meant to cool large rooms due to its smaller output.

4. SPT WA-1211S:

This is one of the most underrated AC units that currently sell on Amazon. For reasons unknown, Amazon’s description doesn’t do justice to this unit. For starters, it has a colossal power of 12000BTU’s and costs a very reasonable $399. It can easily cool a medium to a somewhat large sized room and has 3 fan speeds, i.e. low, medium and high.

It also has a remote that makes adjusting the unit a real breeze. It also has an active LED to indicate the current temperature and an energy saver mode for longer usage periods. All in all, it is one of the air-conditioning units to get if you don’t want to spend a lot of money and want something fairly powerful.


Pros: Huge cooling power, can be controlled with remote, many setting and adjustments just to have the room just as you like it, dehumidifying mode to reduce internal room humidity, comes with a washable filter.
Cons: Heavy, not as power efficient, questionable customer support service.

5. Frigidaire’s FFRE1033Q1:

Frigidaire is one of the more common names in air conditioning as you know by now. The strangely named FFRE1033Q1 is one of their more powerful window-mounted air conditioners that come with a cooling capacity of 10000 BTU’s.

It can cool rooms of up to 450 square feet which is excellent given its rating and it is also one of Frigidaire’s more efficient air conditioning units that they have on sale currently. It costs $399 approximately, but it is a worthy consideration especially if you are looking for a good and reliable air conditioner at a decent price.


Pros:Remote controlled, very energy efficient, remote temperature sensor, built in ionizer, quiet compressor.
Cons: Poor quality plastics and overall cheap construction, questionable quality control, temperature reading can become inaccurate after a few months of usage.

6. Frigidaire’s FFRE1233Q1 12000 BTU:

This is a beefier model of the FFRE1233Q1 range. It has an outstanding cooling rating of 12000 BTU. With the updated power, it can cool rooms of up to 550-600sq feet in dimensions, and Dehumidification up to 3.8 pints per hour, but there are reports of users using it for cooling spaces larger than that courtesy of its incredible strong throw.

This, like its 10,000BTU brother, shares almost all the qualities and cons but the amazing thing here that it is actually priced lower than the 10,000BTU model in certain outlets.


Pros: Very power efficient like its smaller cousin, built-in ionizer for cleaning pollens and other microbes, automatic temperature adjustments, very silent.
Cons: Cheaper construction materials used, the quick dehumidifier means that water collection is pretty fast and it may affect window placement.

7. Frigidaire 6,000 BTU 115V Window-Mounted Low Profile Air Conditioner:

Well, it is, as the name says, a low profile air conditioner for window mounting. This is good if you have limited space in your apartment and want to retain some of the window space to have sunlight come in. The best thing about this model is that it’s incredibly compact, but despite that, it has a fairly impressive 6000BTU’s of cooling potential. This means that you can easily cool medium-sized space with this and due to its low profile, it won’t even hog too much of the space. Also adding to that is that it uses a standard 115v electrical power output to keep it running and has a powerful dehumidification of up to 1.5 pints per hour. Due to its unique proportions, it comes in at about $300-500 which is fairly steep.


Pros: compact size, excellent construction, can be controlled remotely, powerful dehumidification.
Cons: A bit loud, no ionizer considering its price, the quality of the louvers seems bad, not as efficient.

8. Frigidaire FFRE0533S1:

It is a fairly new model from Frigidaire. It is also one of the best value models on this list, and there is a good reason. Although it has only 5000BTU, yet the energy saving ratings alone make it one of the most efficient air-conditionerson this list. It can cool spaces of up to 150-200sq feet easily and is ideal placing it in places where window space is relatively less.

It is also fairly compact but has no ionizer. It has an energy star rating of 12.2 which a very good rating whichever way you put it. It also acts a dedicated dehumidifier displacing of about 1.1 pints of water every hour.


Pros: incredibly energy efficient, compact and light, doesn’t require a lot of expertise to install, all mounting hardware provided with the package,
Cons: Relatively loud, the energy saving mode constantly turns the unit on and off so long-term durability is questionable, not very powerful courtesy of its 5000BTU cooling rating.

9. Frigidaire FFRE0533Q1 5,000 BTU 115V Window-Mounted Mini-Compact Air Conditioner:

It is like a higher end version of the standard FFRE0533Q1. Amazingly though, prices manage to remain incredibly similar to its cousin, coming in at just $199-$208. It also has a fairly modest cooling rating of 5000BTU and is good enough to cool a small sized room.

The area where it gets the upgrade is that it has a dedicated ionizer as compared to the previous model and but shares almost all of its other good traits like trouble-free operation, energy efficiency courtesy of its similar 12.2 energy star rating. It also manages to act as a dehumidifier, displacing about 1.1 pints of fluid.


Pros:ionizer for fresh and pollen-free air, compact and lightweight, very affordable, comes with all mounting hardware with the package, can be controlled with the remote.
Cons:Loudoperation, consistent air conditioner cut off in power saving mode, hence, durability is questionable, limited in cooling power.

10. LG LW8016ER:

Who hasn’t heard of LG? They are one of the world’s leading manufacturers of consumer electronic goods and are well known in the air conditioning market as well. The LW8016ER is their medium sized unit with 8000BTU’s of cooling power. Unfortunately, however, LG isn’t known for its long-term durability for its air conditioners, and there are reported cases of it going wrong just after a few months. It would be better to skip this model even though it has a very compelling price of $250. All is not bad though as it is one of the few air conditioners in this price bracket to come with all the necessary features that you would want in an AC.


Pros: Good pricing, very efficient in cooling, comes with a very impressive rating of 12.1 in the energy index, 3 stage fan controls, relatively quiet.
Cons:Long term durability is questionable.

So, those were some of the best air conditioner units that you can get on a budget. So, buy one which fits your needs and budget the best. And as discussed, keep in mind the room size before buying an air conditioner – because a huge unit with 18,000 BTUs for a small room will be an epic overkill, and on the flipside a small 5,000 BTU in a big room will just frustrate the heck out of you. You will still be in a steambox, plus you will be really pissed that you have an AC unit on, you can hear it purring, yet sweat beads are rolling down your forehead – not a good situation. You can also consult online window AC reviews to make an informed decision, and it is always advisable to take public opinion into account because they will have the first-hand experience of living with the product on a daily basis.
