Why It's Sometimes Better To Choose A Smaller, More Affordable AC
Keeping your home cool during the summer months can be a real struggle, especially if you live in a warm climate. It's normal to crave a cool environment in your home, a space that's supposed to be comfortable and relaxing. This desire can lead to the temptation to invest in a large, elaborate air conditioning unit that promises instant relief and is more than powerful enough to cool your space. But large air conditioning units, though they will certainly cool your home, come with a significant downside. Installing a unit that cools a room too aggressively is inefficient and can end up driving up your electric bill. In addition, that big, expensive unit may end up wearing out faster than an appropriately-sized and more affordable one.
No matter the type of air conditioner you are considering, whether it's a window unit or a ductless unit like a mini-split system, you will spend a good amount of money to get one. Window units range from $150 to $750, and mini-splits and central air systems can range from a few thousand dollars to well over $10,000. So, not only is it important to consider energy costs, but you also want the air conditioner to last as long as possible to avoid the cost of replacing the unit sooner than anticipated. Understanding the different sizes will help you make an informed decision when choosing an air conditioning unit for your space.
The downsides of air conditioners that are too powerful
If you are eyeing a powerful window unit, thinking that the stronger it is, the better, there are some reasons to think twice. Although it may cool a room down quickly, it will do so before having the chance to remove the moisture from the air. This will leave you with a cold, humid room, which isn't generally considered comfortable. Also, since the unit's cycle will be cut short from reaching the set temperature too soon, damage to the inner components, specifically the compressor, can occur. An air conditioner's compressor is designed to run for lengthy durations, rather than frequently switching on and off. The extra stress of short cycling can cause an air conditioner to struggle and wear out before its time. Of course, the rapid cycling won't do your electric bill any favors, either. This applies to all air conditioners, from window units to central and ductless systems.
When buying a new air conditioner for your room or home, there are some general rules to go by. The equation to determine which unit to choose is 30 to 60 BTUs (British Thermal Units) per square foot of space. Additionally, the warmer the climate zone you are in, the higher the BTUs you need. High ceilings and large sun-facing windows should also be taken into consideration. If you're unsure about the right unit size for your home and climate, an HVAC specialist can help you choose the most suitable one.
