Las Vegas furnace repair — 24/7 no-heat emergency, all makes serviced
24/7 emergency furnace repair for no-heat calls across Las Vegas. Licensed technicians, straight pricing before wrenches turn, parts on the truck for 80% of common failures. Ignition, blower motor, gas valve, flame sensor and control board diagnostics.
The five failures that cause 80% of Las Vegas no-heat calls
1. FLAME SENSOR (dirty): the small metal rod that senses whether the burner actually lit. Carbon buildup means it can't sense the flame, safety trips off. Cleaning: 15 minutes. Replacement if damaged: $80-$140. Most common single failure.
2. IGNITOR (hot surface ignitor cracked): the ceramic element that lights the gas. Cracks with age (typically 5-8 years). Symptom: furnace tries to light, gives up. Replacement: $180-$280.
3. BLOWER MOTOR (capacitor failed): the run capacitor that keeps the blower motor spinning. Symptom: blower hums but doesn't turn. Cap replacement: $150-$220. Full motor failure: $450-$750.
4. GAS VALVE (stuck closed): rare but happens. Symptom: pilot lights but main burner doesn't. Replacement: $350-$650.
5. CONTROL BOARD (relay failed): the brain that coordinates ignition sequence. Symptom: erratic behaviour, error codes. Replacement: $400-$650 typical.
During diagnostic, we test all five plus combustion analysis. Straight pricing before repair. Related in Las Vegas: furnace repair and furnace tune-up.

Repair or replace
The 50% rule for repair-vs-replace decisions
Rule of thumb: if the repair is more than 50% of a new furnace's cost AND the current unit is over 12 years old, replacement usually makes more sense. Efficiency gain (typical old unit at 78% AFUE vs new 96%+ AFUE) means gas bill savings that pay back most of the replacement cost in 6-8 years.
Under 8 years old: almost always repair. Modern furnaces have 10+ year expected life, and the parts warranty likely covers most of the cost.
8-12 years old: judgment call. Repair if it's a $200 fix on a still-well-running unit. Replace if it's a $600+ fix that signals the equipment is entering end-of-life failure mode.
Over 12 years old with a $500+ repair: replace. The math almost always favours a new high-efficiency unit with rebate eligibility. Related in Las Vegas: furnace repair and furnace tune-up.

Depends on the failure and the repair cost. Under $250: usually repair. $250-$500: judgment call. Over $500 on a 15+ year furnace: usually replace and take advantage of federal rebates on a new high-efficiency unit. We give honest recommendations — we'd rather sell you the right decision than push a repair or replacement.
Furnace quit at 11pm during a January cold snap. Called them, live response, tech was in the basement by 1am. Cracked ignitor, replaced from truck, heat back on before 2. Straight pricing, no midnight upcharge shenanigans.

Third HVAC company diagnosed 'bad motor' and quoted $850. These folks tested and found it was actually a bad capacitor — $180 fix. Motor is still running fine 18 months later.

Suspected cracked heat exchanger on 22-year-old furnace. They confirmed with a combustion analysis and honest photos of the crack. Gave us the honest 'replace, don't repair' conversation with numbers on both paths.

Newer high-eff furnace had a control board fail at year 4. Under warranty. They handled the manufacturer parts claim and only charged us the labour. Smooth process.
