What Is the Best Energy Efficient Window Air Conditioner?
1. Frigidaire FFRE0833S1 8,000 BTU Window-Mounted Room Air Conditioner Review

This Frigidaire unit is the only one on our list to earn an “Energy Star Rating” (see below for details), making it the most energy efficient window air conditioner. With a rating of 12.0, you’ll know you are saving money and helping the environment while still keeping cool on those hot days.
Its internal filtration system cleans the air while it cools the room. The ionizer will remove a variety of impurities, including pollen, to keep your allergies from acting up during those high-pollen count months.
With allergy rates increasing year after year, this well might be the most important feature of this unit, especially if you have kids. With the filter reset light, you have one less thing to remember because it alerts you when the filter has to be cleaned.
At 8,000 BTUs, this unit will easily and quickly cool down 350 square feet efficiently. This is perfect for medium sized rooms, offices, or apartments.
It has an energy saving mode which turns the air conditioner off as it reaches the temperature you preset it for, and turns the unit back on if the room starts to warm again.
Sleep mode gradually increases a few degrees over the course of the evening to keep you comfortable on those nights when the temperature doesn’t drop.
It operates at around 55 decibels which is about the same noise level you might find in a typical office with people working in it. So, its quiet operation will allow you to have regular conversations with friends and family, and won’t keep you up all night just to keep you cool.
The cooling fan comes with three different settings so you can customize your desired cooling output and noise level. This air conditioner removes 1.7 pints of moisture from the air per hour.
The digital temperature programmer makes it easy to set the unit to the exact specification you want. You can also switch between Fahrenheit and Celsius temperature measurement, whichever you prefer!
You can set the unit with a timer, making it more energy efficient so that it will not run all night when the temperature cools off naturally.
The unit weighs approximately 60 pounds and is designed to fit windows anywhere from 23 to 36 inches wide and at least 14 inches high. It comes with an accordion frame to customize the width to your window.
It will stick out of the window around 18 inches so you should check to make sure there is clearance, but you should not have to install any extra support as this unit will easily be supported by the window frame itself.
It operates on 115 volts and will plug into any standard home outlet with a ground. So you won’t have to do any special wiring to install, but you should check that you do not overload the breaker you are using for the air conditioner.
If you’re looking for a simple, energy efficient window air conditioner, this Frigidaire model is a great option! You can buy the Frigidaire 8,000 BTU 115V Window-Mounted Mini-Compact Air Conditioner with Temperature-Sensing Remote Control, here
Which Air Conditioner Has the Best High-Tech Features?
2. Frigidaire FGRC0844S1 8,000 BTU Smart Window Air Conditioner with Wifi Review

If you are looking for a window air conditioning unit that is a little more high-tech than the previous model, the FFRC0833R1 is an exceptionally designed unit.
Like the previous model, this unit is designed for rooms no larger than 350 square feet. And it will also plug in directly to your standard grounded outlet in your home or office. It has all of the same height and weight requirements of the previous model.
But where this unit really shines is in its integrated technology. When you connect this air conditioner to your WiFi (yes, WiFi!), you’ll feel like you’re living in the future!
Simply download the free App and you’ll be able to control your air conditioner from anywhere in the world (or from across the room, whichever the case may be).
Within the App, you can program the air conditioning unit to turn on or off at particular times and at specific temperatures. You can wake it up and start it cooling the room while you’re still away at the office so you can come home to your place already cooled down and waiting for you to relax. Or you can program it to night time mode so that you do not have it running continuously when there is no need.
You can even program the unit to operate on a 24-hour cycle, turning on and off at particular times. And you can set more than one schedule for weekdays and weekends! Keeping you cool has never been easier.
This model has an Energy Efficiency Rating of 12.0, so you know you are not wasting your money. The sleep mode also adds to these saving features by automatically putting the unit to sleep whenever it reaches a certain temperature. This allows you to maintain a consistent temperature all the time without the room getting too cold or destroying your electric bill.
If you happen to shut off your air conditioning unit, or the power goes out, the Effortless™ Restart feature by Frigidaire will remember your settings and reload all your programming. It also restarts automatically once the power comes back on after a power outage.
With clean air filtration and ionizer, this unit will also help to keep your air clean and pure. The antibacterial filter removes room odors and airborne particles for a healthy and comfortable environment. Like the previous unit, this also has the filter reset light to let you know when it’s time to clean the filter.
This air conditioner has 3 fan speeds for more flexibility and removes 1.7 pints of moisture from the air per hour.
This Frigidaire air conditioner with wifi could be what you are looking. If you’re looking for a great air conditioner with the best high-tech features around, this is the best air conditioner for you!

What Is the Best Air Conditioner for a Sliding or Casement Window?
3. Frigidaire FFRS0822S1 8,000 BTU Window-Mounted Slider/Casement Air Conditioner Review

If you are looking for a window air conditioner but have a sliding window or a casement window instead of a standard window, you know that the typical window air conditioner unit will not work.
This is because standard window air conditioning units are designed so that the window closes over the top of the air conditioning unit to create a seal and prevent air from escaping the room. But if your window does not open by sliding the window up, there is no way to create this seal.
So Frigidaire has designed this air conditioner to work specifically with horizontally sliding or casement windows. While standard window air conditioners come with an accordion frame to cover the opening space between the window frame and the unit, the casement unit works a little differently.
Instead of an accordion frame, the casement window air conditioner comes with a panel frame that fits around the unit and which you cut to match the desired length. Once you measure and cut your frame, a plastic window panel will slide right in and cover the opening while still letting through a little light.
If you want more light to come through, some users cut a piece of plexiglass to fit in their panel. The plexiglass lets in more light without sacrificing air leakage or causing drafts. Due to that, this air conditioner can be a little more difficult to install than regular window air conditioners
You will need to make sure that you have at least a clearance of 21 ½ inches to fit the unit in the window. It can be laid on its side for the narrower sliding windows.
Aside from its design to fit in a casement window, this unit comes with many of the same features that the other models on our list have. It features a programmable thermostat so you can customize the temperature, set it to a timer.
It has the energy saver mode, effortless restart and sleep modes like the above models. It removes 3.0 pints of moisture from the air per hour. That’s over a pint of moisture more than the other two models remove.
It has a switch that you can use to close the vents when you need to so your cool air won’t escape on days you don’t need to use your air conditioner or warm air won’t come in. Like the other models, this unit also has the filter alert, but it does not have the air cleaner.
With an energy efficiency ratio of 10.9, you can expect to operate this unit for around $66 per year, but your exact total will vary depending on usage. At this energy level, this unit does not receive an Energy Star rating, but still functions on the lower end of energy expenditure for a model of its type.
It has an 115V grounded plug for use with a regular household outlet, so this unit is pretty much plug and play.
If you’re looking for a sliding window air conditioner or a casement window air conditioner, this is a terrific choice! You can buy the Frigidaire FFRS0822S1 8000 BTU Heavy-Duty Slider Casement Window Air Conditioner, Electronic Controls, Remote Control, here.
What Is the Best Air Conditioner with Heater?
4. Frigidaire FFRH0822Q1 8,000 BTU Window-Mounted Room Air Conditioner with Heat Review

If you are looking for an air conditioner that not only cools the room but also heats the room, this is a great unit for you!
It comes with all the cooling features of the other models on our list: 8,000 BTUs to cool a room up to 350 square feet, air filtration system, customizable temperature settings, sleep mode, etc. It has 3 fan speeds, 3 cooling speeds, and 3 heat speeds.
But what you also get with this unit is a heater. Now, when the temperature drops, your air conditioner won’t sit uselessly in the window. The heat pump is rated at 7,000 BTUs to really warm your medium sized room, apartment, or office. And when things get frigid, the 3,500 BTU heating strips will kick in to make sure you are nice and toasty on those cold winter nights.
It comes with 3 fan settings and directional vents for 8-way control over the direction the cool or hot air blows out of the unit. It has a slide out chassis so you install the chassis first and then push the air conditioner in. Due to the chassis, this unit could also be wall mounted if you prefer.
It also features an extra-long power cord which plugs into a standard 115-volt outlet. Installation is straightforward and easy with the Frigidaire accordion style frame so that it will fit in any window with a minimum opening of 16 ½ inches.
The remote control is also included to make it more convenient to operate from the comfort of your chair, couch, or bed. The remote is able to control all the features of this air conditioner so it is easy to operate.
With an energy efficiency ratio of 9.8, you can expect to pay around $73 per year for typical air conditioning use (not including the heating element). And while this ratio is low, it does not qualify for the Energy Star Rating. It is still relatively energy efficient for a model of its features and functions.
If you are looking for a great combination air conditioner and heater, this Frigidaire unit could be the best air conditioner for you! You can buy the Frigidaire 8,000 BTU 115V Compact Slide-Out Chasis Air Conditioner/Heat Pump w/ Full-Function Remote Control, FFRH0822Q1, here
What Does an “Energy Star Rating” Mean?
The Energy Star Label is a certification overseen by the EPA, which identifies products and services that meet certain high standards for energy efficiency. The main way that the EPA determines which products receive the Energy Star Label is a combination of offering consumers a high-performance, high-quality product which at the same time will significantly reduce the energy costs to the consumer (and hence lower the carbon footprint of the product).
When you see the Energy Star Label, you can be sure that it means that product will cost much less to run compared to other similar models, but still perform as good as or better than its competitors.
In Conclusion
If you need to stay cool, these 4 window air conditioners will get the job done! Whether you just need a standard, energy efficient model with an air ionizer, a model with high-tech features (wifi, which means you can control it from anywhere), a casement window air conditioner unit, or a unit with heater, you’ve now got the best options for each of these needs! You’ll be sure to beat that summer heat now!
