4. Product Features

There are many Casement Window Air Conditioners that offer numerous exciting features. However, more features do mean a higher price tag. Another thing to keep in mind is that you don’t need heaps of features, but useful ones.

7. Availability

This is also an important factor to keep in mind. The market is continuously being updated with new products. If you buy an older model that has been discontinued, it'll be harder to find parts when you need to do maintenance work. This is also true for lesser-known unpopular brands.

Therefore, buy models that have been on market for a year or two from known brands. This will help you to get better customer service and ensure easily available maintenance service.

8. Value For Money

Expensive products come with more exquisite features and benefits. But they come with a higher price tag too.
