Air Conditioner Buying Guide

Before buying any air conditioner, it’s vital to have a few considerations in mind. Will your window accommodate air conditioner units beyond a certain size? How large a room or open space do you need to cool? Would you prefer a remote control or are you okay with routinely making manual adjustments?

Besides questions like these, you’ll also likely want to consider the long-term cost of the product. It does no good to bargain shop for an A/C unit, only to buy one that uses a lot of electricity. Energy efficiency is essential for avoiding waste and saving money.

This guide will address many of the most common terms and concerns about buying a window air conditioner. Read on to learn more information that will help you better settle on the right unit for your home.

Key Considerations when Shopping for an Air Conditioner

How Powerful The Unit Is – One of the first and most important things to keep in mind when shopping for an air conditioner is the room where you’ll likely put it. Too powerful an air conditioner can waste energy and money. A smaller air conditioner unit stops being a bargain when it struggles to cool a room four times larger than the size it’s built for. Before buying an air conditioner, you should take measurements of the space you need to cool.

Factor in room shape, because square foot coverage will change according to the shape of the room. You’ll need to use certain calculations to determine the total square feet in the space, so you’ll know how powerful the air conditioner you need to buy must be in order to cool the entire room.

Air conditioner power is measured by the British Thermal Unit (BTU). The larger the room space, the greater the unit’s BTU must be to effectively cool it. For instance, the best air conditioner for rooms with 150 to 250 square feet of space would generate about 6,000 BTUs per hour. For an area of around 1,500 square space, the BTU number jumps to 30,000.

In addition to power, you should also consider efficiency. For air conditioners, this is measured by an energy efficiency rating or EER. The EER is the ratio of a unit’s cooling capacity (BTU) over the power input, measured in watts (W). The higher the EER number, the more energy efficient the air conditioner.

Settings & Personalization – No customer is alike, and so it’s only natural for you to shop for the best air conditioner suited for your personal preferences. If you’re buying an A/C unit for the bedroom, you want a product that’s robust enough to cool your space, but one that won’t make you feel like you’re sleeping outside in the dead of winter. There are certain settings and add-ons that you should look for before committing to a product.

  • Timer: Wouldn’t it be nice to set your air conditioner and then have it go on and off without you having to tinker with it any further? For customers that are on the go, or would prefer to come home or arrive at the office and find things adequately cooled down, a timer option is essential. Having a 24-hour timer on your air conditioner allows you to plan far ahead as to when you’d prefer your unit to begin or stop cooling.
  • Temperature range: Not every unit operates within the same temperature range. Some of the more powerful ac units have a wider temperature range, capable of cooling a room down to 61 degrees. Because preferences vary, you’ll want to make sure you have an idea what the temperature range is for your unit and how much BTU you need to cool your room to your preferred level of coolness.
  • Remote control: Remote controls aren’t only for the TV. In the modern world, you should have the option to get your air conditioner at the push of a few buttons rather than continually walking back and forth across the room to manually make adjustments. Be aware that some units can be adapted to do certain functions automatically, making it that much easier to cool your room without a lot of fuss.
  • Fan settings: Most units come with two to four fans, with low, medium, or high power settings. Fan cooling can be very energy efficient; additionally, the fan usually runs quiet, which is helpful for enjoying a good night’s sleep with minimal distraction.
  • Filter: Some filters are reusable while others have to be replaced periodically. A good, clean filter can lower your unit’s energy consumption by five to fifteen percent. It’s important to routinely clean or replace your filter, especially if it gets regular use or you happen to own furry pets. Clogged filters can severely impact the air conditioner’s cooling capabilities.
  • Cover: There may be cool nights or cold winter months where using your air conditioner isn’t necessary. In those instances, you might be worried about unwanted cold air seeping through the unit and into your home. It might be wise to invest in an insulation cover for your air conditioner.

Will It Fit Your Space – Air conditioners come in different sizes, and before settling on one, you’ll want to make sure it will fit the intended window. Before wasting money on a unit that won’t fit, make sure you carefully measure your window; you’ll want to be sure the product you’re interested in is the right size. Many units have easy install window kits, making it a quick and straightforward task to adjust the A/C unit so it fits the unique dimensions of your window. Additionally, the side panels in window air conditioners not only help keep the unit in place, but they also prevent excess air from escaping.

Return Policy – Make sure that you have options if you decide your air conditioner isn’t right for you. Check to see if the store or manufacturer has a trial period available. If you’re able to test the product for a few weeks, you’ll feel more secure about the amount of time available for deciding if the product is money well spent or if you should send it back immediately for a refund or alternate item.

Make sure you hold onto any receipt, as it’s common for stores or manufacturers to demand proof of purchase before issuing any kind of refund.

Warranty – It’s possible to initially be very happy with your air conditioner, only to experience problems from several months to a couple of years later. As A/C units can get very expensive, you’ll want to check if the product is covered by a warranty that will allow you to repair or replace it at little or no cost. Read the warranty, because it’s possible that conditions might change as time passes. For example, it’s possible that any defects found within the first year get paid for, but after two years of ownership, the manufacturer will only claim responsibility for specific issues.

Shipping – If not purchasing your unit in person, you’ll want to double-check that it can be shipped to your location. There’s nothing like having your heart set on the perfect window air conditioner only to find the company can’t ship its products to your location. Have answers to a few basic questions about shipping options: Do they ship to non-contiguous states? Is international shipping available, and if so, to which countries? Is free shipping available? Can you pay extra to get your air conditioner delivered faster? You can avoid costly complications by doing as much research as possible before making an order.
