If you’re looking for an air conditioner for a garage with no windows, you’ve come to the right place. Finding the ideal air conditioner for a garage space with no windows can be tricky, but we’ve got the scoop on the best options available!

Types of Air Conditioners for Garages with no Windows

There are three main types of air conditioners that are best suited for garages with no windows:

Window Air Conditioners

Window air conditioners are designed to be used in windows and are not ideal for garage spaces with no windows. However, some window air conditioners can be considered for use in garages with no windows if you have an exterior wall through which you can run the venting for the air conditioner. Be sure to check with your manufacturer before purchasing.

Portable Air Conditioners

Portable air conditioners are usually a great choice for garages with no windows. They work by **** in the hot air from your garage and circulating it back into the space after cooling it. Portable air conditioners typically have more features than window air conditioners, including multiple fan speed settings, auto shut-off, and digital temperature controls.

Through-the-Wall Air Conditioners

Through-the-wall air conditioners are a great choice for garages with no windows, as they are installed directly into an exterior wall. This type of air conditioner is ideal for garages with no windows as it can cool a large area and is both cost-effective and energy-efficient. It’s important to note that the exterior wall in your garage needs to be thick enough to accommodate the through-the-wall air conditioner unit.

Personal Experience

How do I air condition my garage without windows?

As an expert in air conditioning systems, I can tell you that installing an air conditioner in a windowless garage is definitely possible. With appropriate insulation and ventilation, you can cool the inside of the garage with the AC unit. It won’t be as powerful as in a windowed space, but the temperature can still be maintained in a comfortable range.

The key is to know how to properly size the unit for the space. If an air conditioner is too large, it will cycle too frequently, leading to inefficiency. On the other hand, an undersized unit won’t be able to cool the space correctly. So, it’s important to get the size of your AC unit right.

One additional consideration is to install seals and weatherstripping around the doorways to prevent cool air from escaping. This will make sure the temperature inside the garage is consistent, despite any hot weather outside. To ensure efficiency, you can also insulate the walls, or add overhangs to the building to block the sun.

Overall, having an air conditioner in a windowless garage is definitely possible! With the right installation and maintenance, you can enjoy a cool and comfortable atmosphere, even when it’s hot outside.
