Features to Look for in a Garage Portable Air Conditioner

One thing you can count on is that while shopping for the perfect portable ac unit for garage with no windows, you will be spoilt for choice. We attribute this to the countless brands cropping up daily, and this may make your search harder than it should be.

A smart way of dealing with this problem is by paying attention to select factors, which are as follows:

1. The Power Rating

Most of the air conditioners we came across are rated in BTU, which stands for British Thermal Unit. To boost your knowledge, this is the amount of energy needed to melt a pound of ice.

This measurement will tell the effectiveness of your conditioner in cooling or heating a room of a particular size. In general, the more the BTUs, the larger the space that your air conditioner can cover.

2. Size of your Garage

The other factor that you need to keep in mind is the size of your garage. Obviously, a larger garage will need a more powerful air conditioner than a smaller space.

For instance, garages measuring between 100 to 500 sq. ft will require an ac of 5,000 BTUs to cover all areas. And a space of between 2000-2,500 sq. ft will need a unit of 34,000 BTUs to ensure that all corners of the garage attain the warmth or coolness that you want.

3. Size of the Air Conditioner

Why is the size of your portable air conditioner a critical factor to think about? It is probably due to the size determining the space that the unit will occupy. Luckily, air conditioners come in varying sizes, and you can land something that doesn’t take up too much space in your garage.

It would be wise if you took your conditioner’s dimensions beforehand and compared them to the room you plan to install it in. this way, you won’t end up with a mismatch that would render the unit useless.

4. Noise Levels

We can all agree that most of the air conditioners in the market are noisy and some of us can put up with it. However, if the decibel rating is too high, it may make the entire space unbearable, and even a conversation with a friend would be impossible.

However, if you will be using a lot of power tools in your workshop, the air conditioner’s noise will not bother you at all.

5. Energy Consumption

How do I know the level of energy that my air conditioner will be consuming? In this instance, you have to look at the EER rating. If the rating is above 12, you can count yourself lucky as that is an energy-efficient unit that won’t leave you with abnormal power bills.

Keep in mind that a unit with a higher BTU will need more energy than that with a lower one to run. On top of that, if you get an ac that is too small for your garage, you can expect it to use more power since more energy is needed to run it.

6. Ease of Maintenance

If you want your portable air conditioning unit to remain effective for many years to come, you will have to be consistent in the maintenance practices. So, it would make sense if you landed a product that would give you an easy time to maintain it.

Here, you should look out for removable and washable filters and built-in indicators to alert you that the unit needs cleaning.

How To Increase Garage Portable Air Conditioner Efficiency

If your air conditioner is facing some efficiency issues, worry no more, as we shall provide you with some tips on the areas that you can use to beat the problem.

I) The Garage Door

Consider insulating your garage doors so that they do not absorb too much heat during the day. This way, your air conditioner will be a more efficient performer as it won’t have to do a lot to keep the temperatures down.

II) The Walls

It would be a good idea to insulate the garage walls, starting with those being hit directly by the sun, followed by those shielded away. This will help minimize the amount of heat getting in your garage, and your air conditioner will end up giving a more efficient performance.

III) The Ceiling

The other part you may focus on is the garage ceiling, and this applies to the workshops with a room above. You find that such a garage absorbs a lot of heat from the space above, which may make the entire area intolerable.

The best way to handle this problem is by installing rolled insulation to the garage ceiling. With the temperatures lowered, your AC’s efficiency will greatly improve.
