Window Air Conditioner Buyer’s Guide

Benefits of Purchasing a Window Air Conditioner

A window air conditioner is able to emit cool air into the room, combatting warm and humid climates. Many brands of window air conditioner are available at a low price, with some prices starting as low as $100. However, the more powerful window air conditioners which also emit warm air can cost up to $2,000 to purchase. The good news is that there is a wide range of window air conditioners available on the market to suit all budgets and all needs.

Furthermore, another benefit of using a window air conditioner is that after installation the product does not take up floor space, being perfect for smaller homes and apartments or in rooms where there is a large amount of furniture.

Energy Efficient

Window air conditioners are very energy efficient, being much more cost effective than using central air. Many window air conditioners possess a fantastic energy efficiency ratio or EER, which is the calculation between the window air conditioner’s cooling power and how much energy is needed to run the device. Some of the most energy efficient window air conditioners are provided with a energy star certification.

Furthermore, save energy and money by keeping the window air conditioner turned on even when summer days turn cooler, as turning your air conditioner off until conditions get warmer will result in your system having to work harder and using more energy.

Easy Installation

Most window air conditioners are easy to install yourself. A specific set of instructions are included with every model which are easy to follow by completing the step-by-step instructions. In this way, you can save money from employing the services of a tradesperson, although you may need a friend to help you to install the window air conditioner yourself.

Window Air Conditioner Maintenance

There are several steps to take in order to ensure that your window air conditioner stays in the best condition possible and that you experience longevity and value for money from your product. Ensure that you clean the condenser on a regular basis, preventing lint from clogging up the system. Strategically close the vents to prevent unwanted air from entering the room, particularly if rooms are not regularly used. Similarly, ensure that furniture or curtains are not blocking the vents, allowing air to move around freely.

It is also a good idea if you service your window air conditioner regularly, checking for any problems or potential problems and repairing those issues before they escalate. Furthermore, ensure that you replace the filter regularly. Ideally, every three months as not replacing the filter regularly can mean that the system begins to work harder and may subsequently freeze over. Additionally, you could install ceiling fans within your home, ensuring that your window air conditioner does not have to work as hard.

What does BTU Mean?

BTU stands for British Thermal Unit and is the rating which shows the level of cool air or warm air which the window air conditioner can expel into the room. Subsequently, the higher the BTU number, the more cooling power or heating power the window air conditioner is able to provide to the room. It is important to look for the BTU level when purchasing a window air conditioner, particularly if you are planning to install the window air conditioner into a large space.

How long does it take to Install a Window Air Conditioner? Can I install it Myself?

All window air conditioners come with do-it-yourself instructions which make it perfect for you to install it yourself. On average, the window air conditioner should take around six hours to install fully, although you may feel more comfortable employing the services of a tradesperson.

Alternative: Best through the wall air con units.

Does every Window Air Conditioner come with a Warranty?

No. Ensure that you are aware of your warranty rights before you purchase a window air conditioner. Some companies do provide a warranty although some companies do not provide any warranty at all. Purchasing a window air conditioner with a warranty provides excellent value for money, so ensure that you know your rights fully before you buy.

How many Square feet will my Window Air Conditioner Cool?

This depends on the BTU of the window air conditioner. BTU stands for British Thermal Units and tells the user how much cooling power the window air conditioner will have in the room. On average, 10,000 BTU will provide around 300 square feet of room coverage, keeping your room comfortable and cool. Usually, the BTU of a window air conditioner is measured in 12,000 BTU, therefore providing around 400 square feet of coverage. 24,000 BTU will allow 800 square feet coverage while 36,000 BTU will provide coverage of up to 1200 square feet.

Expert Tip

Search for window air conditioners which contain the option to expel warm air in addition to cool air, providing usage all year round, regardless of the weather and the temperature outside.

Did you know?

It may be more cost effective to use a window air conditioner as opposed to using central air, depending upon the size of your home. For smaller homes or apartments, installing a couple of window air conditioners will definitely be more cost-effective than central air. However, a larger home will most probably possess numerous windows and therefore numerous window air conditioners, so using window air conditioners may not be more cost-effective than using central air.
