While an AC's capacity typically matches its energy usage, an undersized air conditioner will use more power simply because it is likely to run continuously, barely stopping for breath.

What happens if AC unit is oversized?

An oversized conditioner will be overly efficient in that it will reach the desired room temperatures too fast, which results in shortened cooling cycles. The stop-start operation caused by these short cycles can put increased strain on the air conditioner, much like what happens when it is undersized.

What happens if AC is undersized?

Undersized Air Conditioner

An undersized AC will still work but not to the degree you want it to cool your house. Even though it works tirelessly, it will fail to deliver the right comfortable temperature. It means that you must keep it on all the time, yet the house will never feel cool enough.

Can a HVAC unit be too big?

Therefore, the more tonnage the AC unit is rated for, the more air it can cool down.

How long do AC units last?

While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
