A thorough tune-up catches a weak capacitor or a dirty coil months before it becomes a no-cool emergency.

If you're dealing with a system that's never had a real inspection since installation, or one that's due for its seasonal tune-up before the first heat wave or cold snap hits, you already know most emergency HVAC calls trace back to a small issue that a routine tune-up would have caught months earlier.
