Why Size Matters with Your Home AC System
May 26, 2025While a new air conditioning system is typically a big investment for families throughout our service area, a bigger system isn’t always a better one. Instead, and for your AC system to deliver the kind of long-term comfort you desire, it needs to cool your home as efficiently and effectively as possible. And sometimes, going smaller is exactly the right move.
Here’s more on AC system sizing and how it impacts your investment in improved home comfort.
Why Bigger Isn’t Always Better
While an oversized AC unit may cool your home quickly, it will likely do so unevenly. This results in hot and cold spots throughout the house; and when that happens, the system may shut off before it can properly dehumidify the air. Conversely, an undersized unit will struggle to keep up, running continuously and still falling short of your comfort needs – especially on those extra hot and humid days we all dread.
“Short Cycling” Drives Up Energy Costs
An oversized AC system is one that cycles on and off frequently, a process known as “short cycling.” Short cycling tends to drive up your electricity bill while wasting valuable energy. On the flip side, a properly sized AC system operates at greater efficiency rates and helps keep your energy costs down.
Short Cycling Leads to Premature Equipment Failure
Short cycling caused by an oversized air conditioning system places unnecessary wear and tear on system components. An overworked undersized system is also at risk of early failure. In both cases, the lifespan of the unit can be significantly shortened.
Proper Sizing Impacts Indoor Air Quality
While the temperature your AC system can reach and hold is a key consideration, so is the quality of the air all around you. In fact, newer AC systems do a great job removing excess humidity from your home. But if the system doesn’t run long enough during each operating cycle, optimum levels of comfort can’t be achieved.
