Honda looses hp when i turn ac on?

Why every time i turn on my ac my car gets weak like it looses alot of hp?

Air conditioner compressors use several horsepower when running.

The energy required to rotate the a/c pump puts a slight strain on the engine.
Normal and typical.
Think of pedaling a bicycle alone and then adding weight to the bicycle.
You have limited force as does the engine in the Civic.

Of course, your now using some HP to run the AC compressor, LOL. You probably have engine issues if you can notice the drop of power that much.
