Why I Can’t Live Without My Portable AC Unit in the Garage
As someone who spends a lot of time in my garage, having a portable AC unit has become a necessity. The garage is not only used for storage, but it also serves as a workshop and an extra living space during the warmer months. Without proper cooling, it becomes unbearable and almost impossible to use.
One of the main reasons why a portable AC unit is necessary for my garage is because it provides instant relief from the heat. Unlike central air conditioning, which takes time to cool down a large space, a portable unit can quickly cool down a smaller area. This is especially useful when I am working on projects that require me to spend hours in the garage.
Another reason why I can’t live without my portable AC unit in the garage is its versatility. It can easily be moved around to different areas of the garage depending on where I am working or spending time. This allows me to have targeted cooling where I need it most, rather than wasting energy and money on cooling the entire space.
Furthermore, having a portable AC unit in the garage helps protect my belongings from extreme temperatures. With high temperatures and humidity levels, items stored in the garage can get damaged or even ruined.
My Buying Guide on ‘Portable Ac Unit For Garage’
If you have a garage that is not connected to your home’s central air conditioning system, or if you use your garage as a workspace, then investing in a portable AC unit for your garage is a smart choice. Not only will it keep you cool during hot summer months, but it can also help preserve tools and equipment from heat damage. However, with so many options available in the market, it can be overwhelming to choose the right portable AC unit for your garage. In this buying guide, I will share my experience and tips on what to consider before purchasing a portable AC unit for your garage.
1. Consider the Size of Your Garage
The first thing to consider when buying a portable AC unit for your garage is the size of the space you need to cool. Measure the square footage of your garage and look for an AC unit that is suitable for that space. A general rule of thumb is that for every 100-150 square feet of space, you need around 5,000 BTUs (British Thermal Units). So if your garage is 300 square feet, you would need an AC unit with at least 10,000 BTUs.
2. Check the Power Source
Next, consider the power source available in your garage. Most portable AC units require a standard electrical outlet to operate. However, if your garage does not have one or if you plan on using the AC unit in multiple locations (such as camping), then look for units with rechargeable batteries or ones that can be powered by a car’s cigarette lighter.
3. Look for Energy Efficiency
Since portable AC units are meant to be moved from one location to another easily, they tend to be less energy-efficient than traditional window or central air conditioners. However, some models come with energy-saving features such as programmable timers and sleep modes that can help reduce energy consumption. Look for units with high Energy Efficiency Ratio (EER) ratings as they will save you money on electricity bills in the long run.
4. Consider Noise Level
If you plan on using your garage as a workspace or living space, then noise level becomes an important factor to consider when purchasing a portable AC unit. Look for units with lower decibel levels (dB) or ones with features like quiet mode or low fan speeds.
5. Check Additional Features
Some portable AC units come with additional features that can make them more convenient and user-friendly such as remote control operation, dehumidifying function, and air purifying filters. Consider which features are important to you based on your needs and budget.
6 . Read Reviews and Compare Prices
Before making any purchase decision, it is always helpful to read reviews from other buyers who have used the product before. This will give you an idea of its performance and durability. Also, compare prices from different retailers to ensure you are getting the best deal.
In conclusion, investing in a portable AC unit for your garage can make working or spending time in there more comfortable during hot weather conditions. Consider factors such as size, power source, energy efficiency, noise level and additional features before making your purchase decision. With this guide and careful consideration of your needs and budget, I am confident that you will find the perfect portable AC unit for your garage!
