The Rules for Keeping Cool As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space.

How do I size my home air conditioner?

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.
Is it better to oversize or undersize AC?
Construction Advice: When sizing a cooling system for a home, keep in mind that it’s better to undersize than to oversize. A smaller system may run a bit more often, but it will cost less to operate. A larger system will cost more to operate, in addition to being inefficient, which will cost more money in the long run.
How do I know if my air conditioner is too big?
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.
