How to Choose the Right Size Air Conditioner for Your Home
Many people assume bigger is better, while others go for the smallest unit to save money upfront. However, the wrong sized air conditioner can lead to higher energy bills, poor cooling performance and even a shorter lifespan for the unit. Understanding how to size your air conditioner properly can help you make an informed decision and enjoy the benefits of a well cooled home.
Air conditioners are measured in kilowatts (kW) which refers to their cooling capacity. The size you need depends on several factors, not just the square footage of your space. While you can use general formulas to get a rough estimate, other considerations such as ceiling height, insulation quality, window placement and local climate all play a crucial role in determining the perfect size. An undersized unit will struggle to keep up on hot days, while an oversized unit may cool too quickly, leading to inefficient cycling and increased energy costs.
The Problems of Choosing the Wrong Size
Oversized Air Conditioners
Bigger isn’t always better and an oversized air conditioner generally cools a space too quickly, leading to frequent on and off cycles known as short cycling. This process wastes energy and places extra strain on the unit, leading to more frequent breakdowns and maintenance issues. Additionally, short cycling prevents the system from properly dehumidifying the air, leaving your home feeling clammy and uncomfortable.
Undersized Air Conditioners
On the other hand, an undersized unit will work overtime to reach the desired temperature, running constantly and driving up your energy bill. It may also struggle to maintain a consistent temperature, leading to hot spots and discomfort. The continuous operation can wear down the components faster, shortening the lifespan of the unit and increasing long-term costs in repairs and replacements.
It’s Always Best to Consult with the Professionals
While DIY calculations can give you a rough estimate, working with a professional ensures you get the right fit for your home. A professional assessment considers all the factors that impact cooling efficiency and helps you choose an air conditioner that maximises comfort while keeping energy costs in check. Additionally, investing in the right size unit not only enhances your comfort but also helps you save on energy bills in the long run.
