That is usually a bad idea. It makes an already undersized motor/pump run outside of its duty cycle, which results in excessive heat. Overrunning the duty cycle of most things is bad enough, but it's worse with air compressors because of what it does to the air. Hot air holds more moisture and as it cools, that water drops out. Water sitting in the tank is not good itself, but it will probably be warm/hot too, so that means the cooling happens in the hose. It comes out through the tools.
Large compressors run less often, cool better (and didn't get as hot in the first place) and are generally better at everything. Not so good on the wallet, can be rather loud, take up space, so it's not all great.
