Choosing the right through wall air conditioner for your space

Understanding through wall air conditioners

What Makes Through Wall Air Conditioners Distinct?

Through wall air conditioners are a popular choice for those who want a permanent cooling solution without sacrificing window space. Unlike window units, these air conditioners are installed directly into a wall, creating a seamless look and often delivering better insulation. They are designed to cool a single room or a defined space, making them ideal for bedrooms, offices, or living areas where you want consistent temperature control.

How Do They Work?

These wall units pull warm air from the room, cool it using an internal refrigerant system, and then circulate the cooled air back into the space. Many models also offer electric heat or heat pump options, providing year-round comfort. The BTU rating is crucial here—it tells you how much cooling or heating power the unit can deliver. For example, a 12,000 BTU through wall air conditioner is suitable for medium-sized rooms, while larger spaces may require higher BTU products.

Why Consider Through Wall Over Other Types?

Through wall air conditioners are often more energy efficient than portable air conditioners, especially when properly installed. They typically have better sealing, reducing drafts and energy loss. Many units come with features like remote control, multiple fan speeds, and programmable timers, making it easy to customize comfort. You’ll also find energy guide labels on most products, helping you compare efficiency and potential savings on electric bills.

What Should You Know Before Buying?

  • Price: Wall air conditioners can range in price depending on BTU, features, and brand. While the initial cost may be higher than some portable units, the long-term energy savings can offset the investment.
  • Installation: These units require a wall opening, which may involve professional installation. Consider the wall thickness and electrical requirements before purchase.
