The Difference Between a COA and an Overhaul: A Flute Repair Guide

Keeping your flute in top shape means regular maintenance, but how do you know when you need a COA versus an overhaul? Here’s a quick guide to help you understand the difference.

What’s a COA?

COA stands for Clean, Oil, and Adjust. This is routine maintenance recommended once or twice a year. During a COA, your technician:

• Cleans the interior and exterior of the instrument

• Oils the key mechanism 

• Adjusts the tension of the pads and keys 

• Ensures proper sealing and response for all keys

It’s perfect for flutes that are in good condition but need a tune-up to stay that way. Check out our COA video here!

What’s an Overhaul?

An overhaul is a full restoration, ideal for older flutes or instruments that haven’t been serviced in years. It includes:

• Complete disassembly and deep cleaning of the instrument

• Replacement of all pads, corks, and felts

• Full regulation, oiling, and adjustments

Think of it as hitting reset on your flute, bringing it back to like-new playability.

Which Do You Need?

• Choose a COA if your flute plays well but just needs regular care.

• Choose an Overhaul if your flute is leaking, sluggish, or hasn’t been serviced in a long time.
