I found this model after being concerned about the noise level of the window air conditioner because I record tutorials for my business. After reading reviews that spoke about how quiet it was, I feel it is exceptionally quiet and significantly quieter than traditional window units.

The window-air-conditioner provides much-needed cool air and complements the central AC, but cannot stand alone in this size room.

I upgraded to a double size AC after using a smaller one for three years, which was too small for the room. The new AC now cools the room effectively.

I need a light weight removable window AC for my home in Northern California, which has a mild climate with only about 3 heat waves per year of 90 degrees plus temperatures lasting 3 days each. The spec states 46 lbs but it feels lighter, so I suspect the 46 lbs includes the side accordion and top steel bracket which I do not need.

Within 5 minutes, I noticed that the unit cooled down the space considerably. After 10 minutes, it started cooling down the attached front ‘family room’ area. And after 20 minutes, the entire downstairs (minus the master bedroom, which is around a corner) was about as cool as my regularly-functioning home AC.

I used the air conditioner in a room that is 236 square feet with no other cooling. It is rated to cool 150 square feet, but it dropped the temperature of the room from 100+ degrees to under 80 within 30 minutes.

Initially unsure if the 12000 btu would make a difference, but it made a huge difference. The central ac kicks on 1/4 off the amount it used to. I faced the problem of the central ac freezing over due to being overworked trying to keep large areas cooled. But after using this air conditioner, all areas are now at 72 degrees on the spot.

I bought this unit because the manual said it had an outside intake vent closure but it does not, which pulls polluted air in during times of smoke from wildfires.

The filter of my window-air-conditioner allows dusty air in around the edges, which clogs up the coils as soon as it gets dirty.

This AC is fairly quiet with consistent noise levels. The compressor does not make any noise while coming on and off, just a consistent hum of the fan.

Things to Consider Before Buying Window Air Conditioners

BTU Rating

The BTU rating of a window air conditioner is a measurement of how much heat the unit can remove from a room in an hour. The higher BTU rating will provide a more powerful air conditioner. A window air conditioner with a BTU rating of 8,000 would be suitable for a room that is up to 400 square feet in size. A unit with a higher BTU rating would be necessary if you have a larger room. Before making a purchase, always take the BTU rating into account to make sure the appliance will be powerful enough to cool the room to the desired temperature.

Noise level

The average noise level of a window air conditioner is around 50 decibels, which is about as loud as a normal conversation. You may want to consider one with a noise level below 50 decibels if you are looking for a quiet air conditioner. The size affects the noise level of the unit. A larger unit will be louder than a smaller unit. A quieter compressor is also important to consider. A rotary compressor is quieter than a piston compressor. It will be harder to hear the unit if the unit is located in a room that is already noisy.

Energy Star Rating 

The energy star rating is a good place to start if you are looking for an energy-efficient window air conditioner. Window air conditioners with an Energy Star rating use less energy than standard models, which can save you money on your energy bills. It will save you 15% of your energy. The energy start model also tends to have better features and performance than standard models. Before buying an AC always consider the unit's energy star rating. The higher the rating, the more energy efficient the unit will be. You should also look for a unit with good features and performance.

Filter Type

There are different types of AC filters are available in the market. The most common type of filter is the pleated paper filter, which is designed to trap dust, pollen, and other airborne particles. If you have allergies or asthma, you should consider a HEPA filter. This filter is designed to remove more than 99% of airborne particles. If you live in an area with high levels of air pollution, you should consider an activated carbon filter. This filter is good for removing VOCs and other harmful airborne contaminants.

Fan Speed

The fan speed will determine how quickly the air conditioner can cool the room. There are three different fan speeds. The low fan speed is good for small rooms that do not get very hot. The medium fan speed is good for rooms that are a little bit larger or get hot during the day. The high fan speed is good for very large rooms that get very hot during the day. Check the size of the room where the window air conditioners will be installed.

Extra Features

You should also consider some extra features, like smart reminders and sleep mode. The smart reminder feature will remind you when it is time to change the filter on your air conditioner. This is a great feature to have because it can help you extend the life of your air conditioner. The sleep mode feature will lower the noise of the air conditioner so that you can sleep peacefully at night.
