Does an air compressor's horsepower rating matter?

Yes. In a nutshell, horsepower can improve a compressor’s recovery time, but it won't make your nailer any faster or more powerful.

Horsepower (hp) in a compressor refers to the power of the engine or motor. The motor powers the compressor pump, which fills the tank with compressed air. Higher horsepower can help the pump fill the air tank more efficiently, reducing your recovery time. However, horsepower does not affect airflow from the tank to the tool. The cfm and psi ratings are more important when it comes to powering your tools.

The bottom line: when selecting your compressor, don't sacrifice a good cfm rate for lots of horsepower; you won't get the performance you need.

Note: When checking a compressor's horsepower, look at the “Running Horsepower” and not the “Peak Horsepower”. Peak horsepower represents the surge of power a motor has when first starting and can be 1.5 to 3 times the amount of power generated during normal operation.
