As the temperature begins the crawl sky high, people across Santa Clara are looking for ways to keep cool. More than just sitting on blocks of ice or using palm fronds to cool themselves, your air conditioner is perhaps the most obvious way to stay comfortable in your home. But if you’re afraid that your utility bills will climb as fast as the temperature, you might look for other options than using your whole-house AC unit. In cases like these, a window air conditioner is an affordable and efficient option for your home. Here at Legacy Air Conditioning and Heating, we service and repair air-conditioners of all shapes and sizes, including window units. Let’s take a look at why a window air conditioner might be a good fit for your home.

A Low-Cost Way to Keep Cool

Perhaps the most obvious advantage of using a window unit is that they are very affordable. Depending on your needs and your budget, you can find a window AC unit for a price as low as $100 and up to more than $2,000. Typically, you’ll find that the average window air conditioner runs about $300.

The price you pay for your window mounted air conditioner will be largely based on your needs and expected usage. You’ll need to figure out the square footage of the room you want to keep cool and the BTUs you will need for that space. BTUs stands for British Thermal Units, and the number of BTUs your air conditioner will need to produce is based on the square footage of the room. For instance, a room that is hundred 150 sq. ft. in size will need about 5,000 BTUs from your AC to keep it cool.

In addition to the BTU output of your window AC, the price will also be affected by the brand name and the features offered. You’ll find that nearly every major air conditioner manufacturer offers a window unit, often in a variety of sizes. The list of features will vary from unit to unit and from brand to brand.

Maximize Your Energy Efficiency

In addition to their low up-front cost, window AC units can help you save even more money thanks to their great energy efficiency. Window air conditioner units are known for their great EER or energy efficiency ratio. This means they do a better job of keeping a room cool using less energy. Most units will advertise their EER on the packaging to give you an understanding of how much energy you’re saving.

An easy thing to look for is the Energy Star certification that is applied to some units under a program started by the U.S. Environmental Protection Agency. This program is designed to help you save money by purchasing energy-efficient appliances.

Your AC window unit is also energy efficient because it only cools one part of your home. Rather than using your larger AC system to keep the entire house cool while you only spend time in one or two rooms, your window AC uses less energy and only cools the rooms you live in the most. This keeps your larger AC system from running and cycling throughout the day, limiting your energy bills while still keeping you comfortable.

Compact, Convenient, and Easy to Install

An added benefit of using a window air conditioner is the fact that it has a very small footprint. Typically, these units fit readily into any window in your home and are light enough that you can install them on your own. This means you can mount them into the rooms that you use the most like your office, bedroom, or living room. They can easily be moved from room to room depending on your activities. Your window AC unit also acts as a great air purifier. That means you can breathe easy in your home, no matter where you are.
