A garage air conditioner is by far the most efficient way to cool your garage. You can choose from the window, ductless split, portable, and evaporative cooling units. But which one to go for, as there are overwhelming brands and models available on the market?

We have developed this guide to reach your decision without wasting much time exploring different options. 

Let’s dig deeper and find out which AC is the best fit for your garage

Types of Garage Air Conditioners

Window Model

These units need to be installed in a window, and they are great for cooling small to mid-sized garages.

Portable Model

Portable models have a lightweight construction and are suitable for smaller garages. You don’t need to install them permanently. 

Evaporative Cooling Model

You don’t need to connect these air conditioners to a window as they work with the help of pads that can absorb cold water and then evaporate it to cool the air. 

Ductless Split Model

These types of AC come with two halves; one is permanently mounted on the garage wall on the inside while the other half is installed permanently outside. Only refrigerant lines and power lines are connecting the two. These units are great for larger spaces. 

Blower fans

If you prefer portability and simplicity, this fan will work best. Plug these fans in like a normal pedestal fan, and its electrical outlet will blow cool air. 

What Features to Look for When Buying a Garage AC

Size and capacity

You need to look at the capacity and size of a garage heater and air conditioner. Choose the right one according to the size of your garage. 

Next, make sure the unit’s capacity and size are suitable according to the space you will install. Finally, you need to look for the right BTUs for this one. 

Noise level

Look for a low noise level rating device. This rating is given in terms of decibels, and the lower it is, the better. Normally A rating of around 50 dB will prove to be very silent as it is lower than human conversation dB levels. 

Portability 

If you are looking to carry your AC and move it around different rooms in your house, you need to look for a portable design that is easy to carry as well. 

Energy efficiency

Make sure you go for an AC that comes with a high energy efficiency rating. In most cases, you need to look for the DOE and EPA-approved Energy-Star certifications. Otherwise, you can also look for the EER (energy efficiency rating) of a unit. 

What size AC should I consider for a 250-square-foot garage? 

For a 250-square-foot garage, you need to go for a 6000 BTU garage air conditioner. A 5000 BTU device is better suited for any garage under 150 square feet. For the garages over 250 square feet, consider going for units that are over 7000 BTUs.

For a 4-car garage, a 20,000 BTU garage air conditioner is recommended. For a 3-car garage, 16,000 BTU, while for a 2-car garage, 12,000 BTU. And for a single-car garage, an 8,000 BTU device is the ideal choice.
