The breaker is going in bad condition!! There are a couple of different ways you can get this done. But you have to get guidance from professionals.

You Must Also Make Sure The Wiring For That Circuit Will Also Handle 20 Amps.

Assuming this really is a 110v ac unit, which was originally hooked to a 20 amp circuit breaker, and assuming that that your service will support the additional load in your breaker panel, then yes you can replace a 15 amp circuit breaker with a 20 amp circuit breaker. Sure, the breaker is less likely to trip. However, for further discussion regarding the intricacies of how many watts can a 20 amp breaker handle, you may want to check this guide out.

And A 15 Amp Switch Can Handle Up To 1500W.

In electrical you can always go bigger, you can replace a 15 amp switch with a 20 amp or you can use 12 gauge wire instead of 14 gauge (thicker wire) as long as the breaker is still the weak point. But for a 20 amp circuit, the outlet has to be a singular 15 amp one. Do you want to know how you can safely gauge the maximum capacitance of a 20 amp double pole breaker handle?

As An Example, A Normal 15 Amp Household Circuit Can Deliver About 1800 Watts To The Circuit.

The wires from a household electric circuit can carry up to 20 amps and in most settings, there are a few 15 amp recipients that connect to a 20 amp circuit breaker. There are a couple of different ways you can get this done. Changing the size of a circuit breaker to increase the available current is a great way to burn your house down, melt an outlet or ruin an appliance.

This will generally be 15 or 20. I warn against this practice because a 20 amp outlet allows the appliances attached to it to draw up to 20 amps, which exceeds the rating of a 15 amp circuit. 15 amp circuits the wire has a rating that allows it to carry up to 20 amps.

Because If You Accidentally Put More Load On An Outlet, It Will Also Damage The Other Outlets.

There are several types of breakers. The reason behind that is to allow several devices to plug in to the same 20. That is 20 more amps than the circuit breaker will allow.
