What happens if your AC is oversized?
An oversized HVAC unit can make your home’s inside temperature uncomfortable. An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. As a result, you could end up with a number of hot or cold spots throughout your home.
How do I know if my air conditioner is too big for my house?
Here are four classic symptoms of an oversized unit:
- High Humidity. Oversized units don’t run long enough to dehumidify indoor air.
- Short Cycling. Because it’s so large, an oversized AC meets your home’s cooling load in ten minutes or less and then cycles off.
- Hot and Cold Spots.
- Shorter Lifespan and Higher Utility Bills.
