What Size Air Conditioner Do I Need?
Choosing the right size air conditioner for your home can be stressful. There are many factors about your home that directly affect the performance, efficiency, and cost of an air conditioning system.
An A/C that is too small can leave your home feeling clammy and uncomfortable, while a unit that is too large will cycle on and off frequently, wasting energy and costing you more on monthly bills.
Don’t worry. Our certified technicians can help you find the right A/C size for your family.
How We Determine the Right Size Air Conditioner for Your Needs
As a general rule, you can multiply your home’s square footage by 25 to roughly estimate the size of the air conditioner you require. On average, a 2,500 sq/ft home needs a unit with 62,500 BUs.
Other factors should be considered, such as:
- Age of Home
- Number of Windows
- Room Sizes
- Average Climate
- Building Insulation
Based on these factors and more, our experienced team of cooling technicians can determine the perfect size air conditioner for your home.
Why Choose a High-Efficiency Air Conditioner?
When we talk about a system’s “efficiency,” we’re talking about the amount of energy it uses. The more energy a system uses, the less efficient it becomes.
An air conditioner with a high-efficiency rating will use less energy to cool down your home, leaving your monthly costs low and your comfort level high.
Find out what size air conditioner you need by contacting our licensed and certified team of technicians.
