How To Find The Best Ductless Air Conditioner for Garage: Buying Guide 

Also known as mini-split air conditioning systems, ductless air conditioners are powerful energy-efficient household appliances suitable for cooling garages and other spaces in the home. However, if you are planning to purchase a ductless air conditioner for garage, you should know the things to consider before making a choice. This way you don’t end up with a product that does not suit your needs. Here are some of the most important things to keep in mind while making a purchase. 

  • Measure the size of your garage: When buying air conditioners, perhaps the most important factor of all incorrectly matching the size of your unit to the space you intend to use it for. Measure the size of your garage in square foot and compare it to the BTU rating of any type of air conditioner you are thinking of buying. 
  • Size and power of the ductless air conditioner: Incorrectly matching your garage to an AC type, you should find out the BTU rating of the AC unit and make a comparison. Typically, a higher BTU will require less time to eliminate hot air from a room than one with a lower rating. 
  • Voltage : This is another factor to put in mind as it will determine whether the AC you purchase can be installed in your home or not. Typically, small units have a standard voltage rating of 110 to 120 volts which is common in most homes. Larger units will require a voltage of 220 to 240 volts. Be sure to check the voltage of your home before purchasing because buying a wrong unit will not only waste energy but can also damage your circuit and cause a fire hazard. 
  • Type of air conditioner (single zone or multi-zone): As the name implies a single zone ductless air conditioner only cools on part of your home using a single outdoor and indoor unit. A multizone unit, on the other hand, can cool more than one part of your home at the same time. This means you can have it in your garage and install another indoor unit elsewhere while using the same outdoor system. Consider the pros and cons of each option and find the one that suits your need the most. 
  • Energy efficiency: The effect of adding a ductless air conditioner on the electricity bill is arguably one of the biggest questions you will need to answer before you make a purchase. This varies from one unit to the other hence the need to check the air conditioners you are considering. The efficiency is measured in SEER (Seasonal Energy Efficiency Ratio). When comparing two units, the one with the higher SEER figure is more efficient. Some units also come with a yearly estimated cost which you can use to compare their efficiency. Additionally, models that are Energy Star-rated are generally more efficient. You can look out for this. 
  • Ease of installation: It is always advisable to have a professional install your unit. But even at that, you should still get an air conditioner that a novice would find relatively easy to install with no extra installation costs. 
  • Additional features: If you are looking for a tie-breaker between two choices you can look for one that has a desirable feature than others has. This could be asleep mode, programmable timer, air filter among other things.  

Why Purchase Ductless Air Conditioner For Garage? 

Deciding to install an air conditioner in any room of your home is a big deal. Not only will you have to think of the cost of purchase and installation, but the entire process of fitting on into your garage can be stressful. But at the end of the day, you will be the one to benefit from it all especially if there is a need for it. So why exactly would you want to go through the stress of installing an air conditioner for your garage? 

First, if you live in an area where the outdoor temperature gets very high and you spend so much time in your garage, installing a cooling device in the garage is certainly a good idea. It will make spending time in your garage a lot more comfortable. What’s more? A lot of things typically stored in garages such as paint or even metal tools should be kept at a cool temperature. Hence, cooling down the temperature in your garage is highly recommended. 

In addition to making your garage more comfortably, installing an air conditioner for a garage can also help with cooling the rest of your home as well. By cooling your garage, the air in rooms that are close by will also be cooled as well. 

Consequently, this will also affect your energy costs as well. The warm air in an uncooled garage may begin to seep in under the door or through other ways into the other rooms in your home. This way, your central cooling or other air conditioning units in the rest of your home will have to do more work to keep the temperature in check. Thus forcing your energy bills to go up. 

Wrapping It Up

Be sure to consider all of the factors mentioned here before choosing a ductless air conditioner to install in your garage. You can also speak to your technician for recommended options and buying tips. If you make the right choice an air conditioner unit can potentially transform your garage and make it a lot more comfortable no matter the temperature outside.
