## Summary
A useful tune-up measures performance: combustion, airflow, temperature rise, and safety controls.

## A strong fit when
- No service in over a year.
- Gas bills higher than similar winters.
- Some rooms colder or the system short cycles.
- You want an independent condition read before a repair-or-replace decision.

## Process
1. Visual and safety inspection. 2. Clean flame sensor, burners, blower area; correct filter. 3. Combustion and draft at altitude. 4. Temperature rise and static pressure. 5. Written findings.

## Common mistakes
Overly restrictive 1-inch high-MERV filters; closing registers in unused rooms; skipping maintenance on newer furnaces.

## Denver considerations
Dry air loads filters quickly; humidifiers need seasonal attention; schedule in early fall.
