What Size Air Conditioner Do I Need?

If you’re considering buying a new air conditioner—whether in a new home or recently-renovated business—it’s important that you take the time to educate yourself on the different types of AC systems. One of the most important factors involved in installing a new AC is size.

When it comes to air conditioner sizing, most people tend to think, the bigger the space, the bigger the AC. While this logic is sound, and in many instances this is true, it’s not always the case. High efficiency models can help you cool a large space without having to have a massive AC unit installed. Additionally, there are a variety of factors to look at when determining which size air conditioner will best benefit your space.

When selecting AC size, consider the following factors:

  • The total volume of your home or business’s space, not just the square footage
  • Window orientation (especially south-facing), age, design, and overall insulation efficiency
  • Insulation of the home or business in general, as well as the age of the building
  • The amount of sun and/or shade the property tends to receive on a daily basis
  • Condition of the any pre-existing ductwork and/or existing ventilation systems
  • Your preferred level of comfort, as well as your energy expenditure budget

These and other factors will greatly affect the size of air conditioner that will be the most beneficial for your unique space. It’s important to take these issues into account before selecting a new AC for your home or business.

Why Does AC Size Matter?

It’s important that you choose a correctly-sized AC system for a few reasons. First, your air conditioner isn’t only responsible for cooling your home or business. It also controls the level of humidity inside your space. An air conditioner that’s too large for the space will cool the room quickly, but will also fail to remove enough humidity. This can lead to inefficiency—meaning you’ll be paying more on your monthly energy bills. Second, selecting the right size AC is one of the best ways to ensure that your system lasts as long as it is intended to. An air conditioner that’s too small for a space will have to work extra hard to provide the comfort level you want. This can lead to the equipment wearing out more quickly than it should, necessitating frequent repairs and eventually causing the system to stop working altogether.

It’s All About Efficiency

When it comes to air conditioners, bigger isn’t always better. In fact, one of the most important things to consider, along with the size of the system itself, is its overall efficiency. ACs are rated with a Seasonal Energy Efficiency Rating (SEER). When selecting a new system for your home or business, you’ll want to look at AC options that have a SEER of at least 15 or above. Additionally, air conditioners that have a variable speed air handler are the most efficient, while two-speed units are the next best option. It’s also wise to take a look at the AC’s ENERGY STAR® rating.
