Choosing the Right Air Conditioner for a Garage

It does sound odd to have an air conditioner in your garage, mainly due to the fact that these areas of the property lack the insulation and energy efficiency to make it worth the money you’ll spend in cooling costs. Since there is very little in the way of insulation, your cool air is likely going to escape outdoors. There are also plenty of gaps and cracks that you just can’t patch up to ensure that you don’t operate the unit all day. Besides the lack of insulation, your garage door is hardly air-tight and the walls are poor barriers for containing your climate-controlled air. Therefore, you’re going to need to take all of these factors into consideration as you select the right air conditioner for cooling your garage. Here are some tips from Virginia propane and oil heat to point you in the right direction.

Why an Air Conditioner?

Since garages are so poorly prepared for an air conditioner, you may want to think about whether it’s a good idea or not. If you work in the garage for much of the day and the temperatures become unbearable or even dangerous, then it might just be the thing you need to stay comfortable.


Right off the bat, you’re buying an air conditioning unit for the garage. This is not someplace that your HVAC system has been designed to accommodate and refurbishing the home so that the vents reach the garage will be far more costly by comparison. With that said, you first need to know the dimensions of the garage so that you can purchase a unit that is big enough to adequately cool the room. In order to do this, you will first measure the garage (or perhaps you can get the information you need from the builders) to ascertain the square footage. ‘ Once you have that, you will then compare that number to the BTU rating on various air conditioning units that are available.

You will likely be considering higher rated options over the lower ones as the former will be able to cool down a larger room in less time. A higher rated unit can also help alleviate the insulation problems and gaps that exist in most garages. High BTU’s cool the room down sooner and you won’t run the unit for long periods of time. That will help you keep those energy costs down.

Ventilation Considerations

Air conditioning units need proper venting and when you’re using one in the garage you may have some challenges as to where you can place it so that it gets the ventilation it needs to operate effectively. Some garages have windows in which the unit can be placed. Others may require getting a little more creative about finding adequate ventilation. It might even mean cutting an insert or hole through one of the garage walls. That’s because the vent on your unit is how the warm air is released and replaced by the cool air that is being produced. Without that ventilation, the warm air is only going to end up back in the garage with the cool air and you will be wasting time and money on an ineffective air conditioner.

Commercial Units

Sometimes bigger is better and in the case of air conditioner units for the garage, choosing something that can handle large spaces and long operating times can end up being the perfect option for any size garage. These units are strong enough to cool down extreme temperatures because they’re built for commercial use.
