Which Air Conditioner Is Best For Large Garages

Garage Portable Air Conditioner DIY Install – No Window?! EASY Venting Idea

For large garages, a window air conditioner or a split AC is the best. They output even more cold air for the same amount of electricity. Window and split ACs have a higher cooling efficiency than portable ACs.

Because they dont have these cheap hoses that portable ACs have and because the hot air-releasing part of the AC unit is always located outside, they dont have the same efficiency problems as portable ACs.

Is There An Air Conditioner That Doesnt Need To Be Vented

As a garage owner, you probably want to spare yourself the hassle of setting up an AC in your garage. But, a vent is necessary.

All air conditioners have to be vented. Any air conditioner that claims to need no vent is a marketing scam and has no technical foundation.

Air conditioners absorb heat from a room. And the heat has to go somewhere. Now, if you dont vent it, the heat will stay in your room and the temperature wont change.

Without a vent, cooling is impossible.

It might be possible to change the perceived temperature of a room without a vent. For example, using a humidifier or a pedestal, or a floor fan. However, this does not reduce the actual temperature.

It only changes your feeling about the temperature.

So: If you want real air conditioning in your garage, you will have to set up a vent.

Best Air Conditioners For Garage With No Windows

Believe it or not, your seemingly useless garage can become a highly functional and productive space if it is ventilated correctly. While most people use their garages as workspaces and studios, they can also be used as garage gyms and other recreational areas.

However, with most garages coming without windows in modern houses, it can get difficult to control the temperature. Trapped hot air creates a stuffy atmosphere inside during summers, while winters can make the space freezing cold.

The best way to regulate the temperature inside your garage is to install an air conditioner. But, what is the best air conditioner for a garage with no windows? Read below to find out.

An Important Note About Garage Insulation

Insulation is the most important aspect of alternating current.

Uninsulated, your garage will barely keep the air fresh !

Insulating your garage is easy, but it can be expensive. It all depends on where you live, how well finished it is and how far you want it to go.

There are several lengths you can reach to insulate your garage. You may need to purchase just a few depending on how long you plan to spend there and how expensive your fresh air loss will be.

However, all the insulation in the world will not solve the common problem of garages: air leaks. While it may not work in a home with old window frames or doors that are slightly larger than the rest, air leaks can be a problem out there.

If cold air manages to escape from them, doors, windows and insulated walls are useless

The insidious part of these leaks is that you may still be able to cool your garage as the air slides out. Also, it will make your air conditioner harder and more frequent. This will result in a higher energy bill and a shorter duration. Not to mention the discomfort of having to wait longer for cooling.

    Properly Venting Hot Air Out Of The Garage

    Every AC unit, including the one in your garage, has to be properly vented. Venting is just letting the hot air out, and there is no way around that.

    For proper venting, you need an opening in your garage. Window venting is most commonly used but for that, you do need a garage window. The exhaust hose is simply installed through the window with a specialized window seal kit that envelops the exhaust hose and covers the window, preventing cool air leakage.

    Of course, everybody who doesnt have a garage window immediately asks this question:

    How do I use an air conditioner for a garage with no windows?

    Heres what you can do: Use an opening in the garage door to vent the air conditioner. Youll have to insulate all the openings that are created when the garage doors are opened. The best choice is to create a hole in the wall yourself especially useful for garage mini-split AC units and vent the air conditioner directly through the wall.

    Heres what you cant do: Use an evaporative cooler for the garage. Its the that these units dont need to be vented, and there is a good explanation for that. Evaporative coolers or swamp coolers are not air conditioners at all they do not decrease the garage temperature, they have 0 BTU of cooling effect, and if put in an insulated space like a garage, they will rather increase the temperature instead of lowering it.

    In short, a window, garage door opening, or drilling hole in the wall are the only 3 options.

    Zero Breeze Mark 2 Best Battery Operated Ac For Garages

    Midea Portable Air Conditioner Overview | Garage Conversion Plans

    Zero Breeze has a portable solution for your home, garage, truck, tent, or camper. The 2300 BTU, battery-powered unit can go virtually anywhere. You wont get stuck without AC either as there is a plug-in power option for any standard 100-240V outlets.

    There are very few battery-powered AC units on the market and although they are not perfect, they can keep your garage cool.

    This is the newest, updated version from Zero Breeze so expect the Mark 2 to be effective in cooling down small areas such as one car garage. If you have a low square footage garage then this can provide direct cooling relief.

    It claims to drop the air temperature 30F within 10 minutes but this will depend on the size of your garage. When using this second-generation Mark 2 AC unit, we found it worked best on areas under 50 square feet.

    One major difference from the previous AC unit is the dual hose which allows for more sustainable cold and hot airflow.

    We recommend placing the heat dissipation pipes out of a door or window so they draw air from outside, cool your workshop area down, and flush the warm air back outside.

    When you unpack the machine, it is almost ready to use. However, because of the refrigerant, you will need to let the AC sit for a few hours to allow the fluid to return to the compressor.

    If you run the unit prior to the refrigerant settling, you can ruin the compressor and void your warranty.
