Air conditioning units are excellent investments that will make your home more energy efficient and comfortable by enabling you to regulate your indoor temperatures. However, for you to enjoy the many benefits from your air conditioning unit, you have to invest in the correct one. To help you, here are a few things you may want to prioritise on your checklist.
Size of the Air Conditioning Unit
The size of the air conditioner will determine its cooling capacity. This means if you want your AC unit to be effective in cooling your home, you need to choose the correct size. If you choose an oversized unit, it can easily short cycle, leading to insufficient movement of air and poor control of humidity. On the other hand, an undersized air conditioning unit will not be enough for the cooling load. Fortunately, a few things will help you choose the perfect size. First, start by evaluating the size of your rooms including the ceiling height. This will help you find out the amount of air in those rooms that need to be cooled. The larger the room, the more the cooling load.
Look at your household size too. Since people emit heat, the higher the number of people in your house, the more cooling capacity is required, which means you will need a larger unit. If the room in which you want to install your AC unit is close to your kitchen or has more of its walls exposed to direct sunlight, the cooling load will be more due to proximity to the high temperature areas. This means you want to go for a large-sized unit.
Humidity levels are the thing to watch out for when evaluating the climate. This is because humidity affects the type of air conditioner you can select as well as where to install it. For instance, an evaporative air conditioning unit won't be a good option if you live in a relatively humid area. This is because these types of air conditioners work by adding moisture to the outdoor air, and with a lot of moisture already in the outside air (because of high humidity), these won't be the best of options.
Tip: Once you choose the correct type of air conditioner for your humid region, don't install it in areas such as your laundry room or kitchen, which are likely to create even more humidity. Your AC unit won't work efficiently in those places.
The Material of the Condensing Coils
Usually, the condensing coils are made of aluminium and copper. While units with aluminium coils or tubes may be cheaper, you can't repair the aluminium coils when damaged. You will have to replace them. On the other hand, copper coils are less problematic in the long run because they are stronger, easier to maintain, and more reliable.
