AC Sizing: Why It Matters

Set of Air Conditioning System
|

When it’s time to install a new air conditioner, it’s easy to assume that bigger means better. But when it comes to air conditioning systems, that’s not always the case. In fact, selecting the right size for your home is crucial to achieving comfort, energy efficiency, and long-term reliability. At All-Phase Heating & Cooling, we help homeowners throughout Winston-Salem and nearby areas like Advance, Clemmons, High Point, and Kernersville make the smart choice with properly sized AC systems.

Why Proper Sizing Is Essential

AC sizing refers to the system's cooling capacity, typically measured in tons or BTUs (British Thermal Units). The ideal size is based on more than just square footage. A professional assessment includes factors such as:

  • Home layout and insulation levels

  • Number of windows and their orientation

  • Ceiling height

  • Local climate and sun exposure

  • Occupancy and appliance heat output

When any of these are overlooked, you may end up with a system that doesn’t work efficiently—and that means more stress on your system and higher energy costs.

What Happens If the AC Is Too Big?

An oversized air conditioner will cool your space quickly, but that’s not always a good thing. Because it cycles on and off more frequently, it won’t run long enough to dehumidify the air. This can leave your home feeling damp or sticky despite a low temperature setting.

Short cycling also causes increased wear and tear, which can lead to frequent repairs and a shorter system lifespan. You might end up spending more on an oversized system that underdelivers in comfort and reliability.

What If It’s Too Small?

An undersized AC, on the other hand, may run constantly without ever reaching the temperature you want. Not only will this skyrocket your energy bills, but it also puts a strain on the system. Components wear out faster, and your home still doesn’t stay cool. It’s a lose-lose situation.
