Understand the choices

Repair, replace, or maintain?

The right answer depends on the test results, condition, compatibility, safety, service history, and what you want from the system.

Repair

Usually considered when testing identifies a serviceable failure and the rest of the system remains a sound investment.

Replace

Discussed when equipment condition, repeated failures, compatibility, comfort, or long-term cost makes replacement more practical.

Maintain

Cleaning, testing, adjustments, and timely follow-up can reduce preventable failures and reveal developing wear.
