Considerations for Purchasing a Window Air Conditioner

If you decide to buy a window air conditioner online, then you’re making a brave decision. The weight and loft of such an item can mean that you have one chance to get it right – otherwise, the return process will be a nightmare.

If the thought of choosing the wrong air conditioning unit and having to send it back keeps you up at night, then it could be time to do your homework. Reduce your risk of making a poor purchasing decision by considering the following criteria.

  1. Cooling Output

    The first and most important thing to consider is the cooling output. If you don’t think about it and only look at the price tag, there’s a high chance you can buy one that doesn’t cool your property effectively. Every window air conditioner is different – with various square-foot and BTU outputs to suit different spaces. Think about where you’re going to put it, then match the square-foot capacity of the one you like to that space.

  2. Heating and Cooling

    When you’re in the market for a new window air conditioner, you want it to cool your house. But what about warming? Some do both. The two-in-one convenience can be worth the additional cost, so weigh up whether you may need to heat and cool your home, or only cool it down.

  3. Settings

    The settings can differ dramatically from one air conditioner to the next. Some are automatic and require minimal adjustment, while others are fully manual. If you like the convenience of “set and forget” then choose a more advanced, automatic model.

  4. Installation Method

    How DIY savvy are you? By choosing a window air conditioner, you are going to have to install it into your window with weather sealing and plenty of muscle power. If there is an option for an installation expert to help, then pay the extra. The task can be mammoth for one person – or one that doesn’t know what they’re doing.
