## Summary
When a furnace stops heating, the useful first step is a measured diagnosis: confirm what failed, why it failed, and whether the rest of the system is healthy enough to justify the repair.

## Common no-heat causes
Ignition, flame sensing, pressure switches and venting, the blower and its capacitor, the control board, or the thermostat and its wiring. Fix the cause, not only the symptom (for example, an overheating limit switch caused by a clogged filter).

## A strong fit when
- The furnace is under roughly 15 years old with reasonable service history.
- One component clearly failed and the heat exchanger, venting, and blower check out.
- Heat is needed now and options should be explained before larger decisions.

## Another option may fit better when
- The furnace is near or past 18 to 20 years and needs a major part: see https://denverfurnacerepair.com/guides/repair-vs-replace
- You smell gas or a CO alarm is sounding: leave and call 911 or the gas utility first.
- Rooms are uneven but heat works: see https://denverfurnacerepair.com/services/furnace-maintenance

## Process
1. Listen first. 2. Observe a safe start-up sequence. 3. Measure voltages, temperatures, gas pressure, and draft. 4. Explain the finding and options. 5. Repair and verify over multiple cycles.

## Factors affecting scope
Which part failed, part availability, access, underlying cause, and timing (after-hours costs more).

## Denver considerations
Cold snaps expose weak furnaces. At about 5,280 feet, gas appliances should be set up for altitude.

## Safe homeowner checks
Thermostat set to heat, breaker and furnace switch on, filter not clogged, panel door closed. Do not open gas valves or bypass switches.
