Aspects to Consider When Buying a Garage Air Conditioner

Keep in mind some of the following qualities when searching for a garage air conditioner:

Size

We all know space is at a premium when it comes to both storage and a working area within your garage. You are going to want to find a unit that will not take up too much space but will still effectively keep the area cool.

Noise

This is probably less of an issue within a garage space than it would be, say, in your living room, but noise definitely still has an impact. You do not want to be struggling to be heard when working on a project with multiple people because of the noise produced by your AC unit.

Energy Efficiency

The thing about portable air conditioners is that they usually consume quite a bit of energy. If you pay attention to a unit’s EER, or Energy Efficient Rating, you can determine just how much energy a unit will expend relative to other units.

If you are looking for a unit that is incredibly easy to operate and will effectively cool your garage to a comfortable working temperature for projects, look no farther than the Honeywell MN10CESWW.

PROS

  • Quiet
  • Easy to Install
  • Can be Remote Controlled
  • Provides for an Even Distribution of Cool Air
  • Will Display Both Current Room Temperature and Set Temperature

CONS

  • Too Heavy to be Moved by Just One Person, Will Require Two People to Transport It

Our Review

The Honeywell HL10CESWW Contempo Series is an excellent, multi-functional air conditioner that will keep your garage as cool as a cucumber. It is smaller than many of the other units available on the market, so it can be easily tucked away into a discreet corner of your workspace.

If you want air circulation but not necessarily cooling, you can just use the fan function, and if it is super humid and you need some relief, this unit provides a dehumidifier function as well. You can also adjust the angles of the air vents so you can get cool air blowing exactly where you would like it.

Best of all, this unit can be programmed to shut off at a predetermined time, so you never have to worry about forgetting to turn it off when you are done with your projects and accidentally leaving it going (and running up your energy bill) all night.

Bottom Line

The Honeywell HL10CESWW Contempo Series is an ideal garage air conditioner with a lot of convenient functions. It is on the heavier side, so plan to have another person on hand if you are trying to move it.

Emerson Quiet Kool EAPC12RD1 Portable Air Conditioner with Remote Control for Rooms up to 250-Sq. Ft.

PROS

  • Quiet
  • Compact
  • Has Good Remote Functionality
  • Durable and Will Last a Long Time
  • Compressor Does Not Jolt On and Off With a Loud Noise

CONS

  • When it is First Running it Can Be on the Louder Side, But That Noise Will Reduce as it moves into its cycles

Our Review

The Emerson Quiet Kool EAPC12RD1 is fantastically simple and easy to use, and will effectively cool large garage areas in a snap. It is straightforward to set up and to program the different settings. It is also on the smaller side, making it ideal to be tucked away into a corner of your garage, or moved into storage when the hotter months are over, allowing that space in your garage to be used for other projects.

Because it is sleek and modern, it will not stick out like a sore thumb no matter where you put it, so this unit could also be used inside the house on really hot days. It has an economy mode to keep your energy costs low and help save our planet a little. It also has a fan mode for times when you need air circulated but maybe not necessarily cooled. And its warranty system really cannot be beaten – you will get a one year warranty overall, three years for the parts, and five years for the compressor. Difficult to get better than that!

Bottom Line


The Emerson Quiet Kool EAPC12RD1 is an awesome air conditioner that can be stored basically wherever you need it, thanks to its smaller size. It can be on the louder side when it is first running but will quiet down as it cycles through.

Types of Garage Air Conditioners

It is best to know the different types of garage units available before you invest in one:

Smart Air Conditioners  

Everything is online these days and your air conditioner is no exception. Smart units can be enabled with WiFi and controlled from afar, so you can set your garage temperature before you even venture out.

Dual Hose Air Conditioners  

If your garage is on the larger side, you will likely want a dual hose unit. Units with dual hoses have separate hose systems for cooling air and expelling hot air, which makes them more efficient and effective.

Multi-Function Air Conditioners

In today’s day and age, nothing has just one purpose. Multi-functional air conditioners can also serve as fans, dehumidifiers, and even heaters – which can really come in handy for keeping your garage warm in the winter months as well.

You get what you pay for and higher quality air conditioners are obviously more effective. It can get pretty heated in a garage when you are working on projects, and can you really put a price on your own comfort?

People Also Ask

Below are some frequently asked questions:

Can You Cool a Garage Effectively?

You may be wondering if it is even worth it to invest in a garage air conditioner when a garage typically has very little insulation and may not be effectively cooled. The answer is that any enclosed space can be cooled, but some may take more effort than others. The draftier your garage, the more efficient a product you will need.

How Often Should I Clean My Garage Air Conditioner?

If you do not clean your air conditioner, odds are eventually its performance will likely be impacted. The amount of use you put into your air conditioner will likely impact how often you need to clean it. If you are running that thing constantly, you should probably check in every couple of weeks to clear out the dust from the back of your unit and ensure optimal performance.

How Big of an Air Conditioner Do I Need For My Garage?

It really depends on the size of your garage. What you will need to look out for when shopping for a unit is the BTU level – this will indicate the amount of space the unit is expected to keep cool. The larger the garage, obviously the higher BTU and larger air conditioner you will need.

How Much Does It Cost to Install an Air Conditioner in a Garage?

Beyond the initial cost of the air conditioner and the time and effort to install it – which can vary widely across different types of models – it should not really cost you anything to install a portable air conditioner in your garage. Though, some units may require purchasing additional insulation if your garage is particularly drafty.
