Window Air Conditioner: 3 Steps for Finding the Best One

Window Air Conditioner

The best time to think about a window air conditioner is before you are sweltering in the middle of July!

But deciding on which window air conditioner unit to purchase can be stressful. There are so many different brands. You have to determine which size air conditioner you need. And then there is the issue of rebates for energy-saving units.

If you plan to buy a window unit air conditioner, here are three steps that you should take:

Step 1: Determine the Correct Size of the Window Air Conditioner
Oftentimes, people buy a window air conditioner that is too big because they think that it will give them a cooler room. In reality, however, a window air conditioner that is too large is ineffective and also wastes energy.

A window air conditioner works by removing the heat and the humidity from the air. If the unit is too big, it will cool the room, but it will only remove some of the humidity. If your air conditioner window unit is too large, it will leave the room feeling damp.

To determine the proper size for your window air conditioner, you need to figure out the square footage of the room where you plan to use it. Then you can determine what size (BTUs) window air conditioner you need.

For a room sized 150-250 square feet, for example, you will need a small window air conditioner. A 6,000 BTU window air conditioner is recommended for such a small room. For a room that is 450-550 square feet, however, a larger-sized unit – like a 12000 BTU air conditioner – is the best choice.

Step 2: Research the Top Brands
There are many window air conditioner units from which you can choose, but there are three models that are routinely well rated. Below you will find window air conditioner reviews for the most popular sizes. All were chosen considering decibel levels during operation, controls/options, airflow, and energy use.

If you are trying to save cash, you might consider purchasing a used air conditioner. To find one, ask friends, family members, neighbors and co-workers if they know of anyone trying to sell one. You can also always try Craigslist. Just make sure you have a professional technician check it out before you buy.

Step 3: Learn about Rebates
Another way to save money is to ask your retailer about rebates. Energy Star-qualified window air conditioners won’t get you a federal tax credit, but some utilities offer rebates of between $30 and $150.

Also, an energy-efficient air conditioner will save you money on your monthly energy bills. To save the most, make sure your window air conditioner meets federal Energy Star standards and has an energy-saver mode.
