Our goal in this review is to help find the best window air conditioner for you. Before the review, we cover several topics that will help you identify an air conditioning unit that meets your needs. You will learn about efficiency, noise levels and what makes some units better than others. There are also some tips to help you with the selection and installation phases. The units reviewed here are a good place to begin your search for your ideal cooling solution.

About Window Air Conditioners

Efficiency: Good for the Environment, Good for Your Budget

When it comes to energy usage, efficiency is good for the environment. When it comes to personal energy usage, it’s good for your budget. Air conditioners measure energy usage in watts and cooling performance in BTUs. Using these two completely different measures, it is nearly impossible for the consumer to determine which units are more efficient than others. For that reason the United States government requires that each air conditioner is assigned an EER (Energy Efficiency Ratio) by the manufacturer. This ratio makes the comparison simple. An air conditioner with a higher ratio is more efficient than one with a lower ratio, saving money and the environment.

Size Is Everything

First, you want to make sure that the unit you choose has the cooling power necessary to cool the room where it will be installed. If it provides too many BTUs of cooling, you may be wasting money. If it provides too few, you may not be satisfied with the results.Second, it must fit the window in which it will be placed. The key dimensions are the width and the height of the open window. The height of the unit needs to fit inside the open window. The same goes for the width, although you might want to get a unit that doesn’t have a gap of more than a couple of inches on each side. This will make it easier to block the gaps and keep out insects and the elements. Also bear in mind that the unit needs to be tilted slightly downward, toward the outdoors, so that water can easily drain.

Cool, But Noisy

When you hear people talk about window air conditioners there is usually some grumbling about the additional cost of electricity or having to take it out for the winter and reinstall it for the summer. When it comes to noise, there is no grumbling. Perhaps the biggest complaint is that they are too loud. All the specifications for units reviewed here include their noise rating in decibels (dB). To help you understand how loud sounds are in decibels, here are the decibel ratings of some common sounds. The loudest air conditioner reviewed here is rated at 68 dB which is at the high end of the scale below.

  • 50 dB: Quiet office
  • 60 dB: Conversation, electric shaver, dishwasher
  • 70 dB: Noisy restaurant, dishwasher, alarm clock

How We Chose Units To Review

The units reviewed here have been selected based on manufacturers’ specifications and customer reviews when available. Units that did not offer a decibel rating, EER or weight were not considered for this review. After size and BTU ratings, these are perhaps the top three criteria that customers look at when purchasing an air conditioner. The units listed are ranked by noise in decibels, with the quietest units first and the loudest units last.
