1. Frigidaire FRA052XT7 5,000-BTU Mini Window Air Conditioner
The Frigidaire FRA052XT7 5,000-BTU Mini Window AC is one of the most basic units on the market. It is at the 5000 BTU level and is really, really simple to use. There is nothing fancy or flashy about this product and, as such, it is one of the lowest priced window air conditioners on the market, putting it in the top spot. This unit has 751 reviews and a score of 4 stars.
2. Frigidaire FRA054XT7 5,000 BTU Window-Mounted Mini Room Air Conditioner
You may do a double take when looking at the name of this unit since only the model number is different, but I assure you, this is a much different unit. The Frigidaire FRA054XT7 5,000 BTU Window-Mounted Mini Room AC is a much nicer looking model and it is much easier to use. It has a remote thermometer and remote control unit that makes it super easy to use. 151 reviews and a 4 star rating.
3. Frigidaire FRA126CT1 12-000 Btu Window Air Conditioner
At the third position we are moving up to a much more powerful unit. The Frigidaire FRA126CT1 12-000 Btu Window AC can cool 640 square feet, provides touch sensitive controls, and has a remote. There are 136 reviews, 27 answered questions, and a 4 star rating.
4. Whynter 14,000 BTU Dual Hose Portable AC
Finally, we have switched brands and unit type, from a window AC unit to a standing AC unit. The Whynter 14,000 BTU Dual Hose Portable AC (model ARC-14S) sits inside your room and provides a variety of functions: air conditioning, fan, or dehumidifier. There are 252 reviews and 58 answered questions and a 4 star rating on this unit.
5. Honeywell MN10CESWW 10,000 BTU Portable Air Conditioner
The Honeywell MN10CESWW 10,000 BTU Portable Air Conditioner is another indoor standing unit and I personally find it much more attractive than the other units here due to the simplicity of the case. There are 107 reviews, 67 answered questions, and a 4 star rating on this unit.
6. SPT 12000 BTU Window Air Conditioner
The SPT 12000 BTU Window Air Conditioner (model WA-1211S) is the first unit to break out of the 4-star category, making it all the way up to 4.5 stars. Customers really like all the features in this unit, though they wish it was lighter. There are 223 reviews, 93 answered questions, and, as stated earlier, 4.5 star rating!
7. Frigidaire FRA086AT7 8,000 BTU Window-Mounted Compact Air Conditioner
The Frigidaire FRA086AT7 8,000 BTU Window-Mounted Compact Air Conditioner takes us down in cooling power compared to the last few units. This model comes with a remote and various other common features but it does not rate as well with owners. This unit has 198 reviews, 24 answered questions, and just a 3.5 star rating. This is probably a model to avoid.
8. SPT SF-609 Portable Evaporative Air Cooler and Ionizer
The SPT SF-609 Portable Evaporative Air Cooler with Ionizer is something a little different. Notice that it is not an air conditioner, rather, an air cooler. This will work well for dry climates but it does not blast out cool air. Make sure to read the reviews to understand what you are getting. At around $100 it is the cheapest item on the list. This item has 232 reviews, 32 answered questions, and 3.5 stars.
9. LG 8,000 BTU Window-Mounted Air Conditioner
The LG 8,000 BTU Window-Mounted Air Conditioner is the only LG model on the list. It cools around 350 square feet and has a standard feature set, including a remote. It is also somewhat less attractive than other, cheaper models. From my perspective, the price point keeps this unit low on the list. There are 124 reviews, 33 answered questions, and a 4 star rating.
10. Quirky + GE Aros Smart Window Air Conditioner
The Quirky + GE Aros Smart Window Air Conditioner was for sale for about 3 days at the time of this post and was blazing up the sales list. The design of this unit is far superior to the other models listed. The usability is also far superior due to the ability to control it from an iPhone or Android. You can even set a budget for the unit and it will stick to it. The trade off for all these features is at the price point since it provides just 5,000 BTU of cooling power, enough for a small to medium room. The Aros is clearly popular with 60 reviews, 160 answered questions, and 3 stars. I expect these numbers to change faster than a race car now that the product is shipping so check the listing for up to date stats.
