Common Heating Problems in Las Vegas
Even in mild Las Vegas winters, heating systems can fail when you need them most. Here are the most common furnace problems in Las Vegas and what they typically cost to fix:
Furnace Won't Start
Most common winter complaint
If your furnace won't turn on, it could be several issues. Start with the simple fixes before calling for heating repair in Las Vegas:
Check First (DIY):
- • Thermostat set to HEAT mode
- • Temperature set above current temp
- • Circuit breaker not tripped

Furnace Runs But No Heat
Blower works, but air stays cold
If your furnace fan runs but the air isn't warm, the burners aren't lighting properly:
- •Dirty flame sensor: Most common cause. Sensor thinks flame is out, shuts off gas. Repair: $80-$200

- •Clogged burners: Desert dust accumulation. Professional cleaning: $150-$250
Furnace Cycles On/Off Constantly
Short cycling wastes energy, causes wear
Short cycling (furnace turning on and off every few minutes) indicates serious issues:
- •Extremely dirty air filter: Replace immediately. DIY: $15-$40
- •Flame sensor issue: Dirty or failing. Repair: $80-$200
- •Thermostat malfunction: Giving false readings. Replace: $150-$300

When to Call Emergency Heating Repair Las Vegas
Some situations require immediate emergency heating repair in Las Vegas, even during our mild winters. Safety always comes first:
CALL IMMEDIATELY
Safety-critical situations
- Gas smell: Turn off gas, evacuate home, call 911 and gas company
- Carbon monoxide detector alarming: Evacuate immediately, call 911
- Yellow/orange flames: Should be blue. Indicates incomplete combustion (CO risk)
- Smoke or burning smell: Shut off furnace, call for emergency service
URGENT (Same Day)
Non-safety urgent issues
- No heat, below 40°F: Especially with children, elderly, or medical conditions
- Intermittent heat during cold snap: Could fail completely overnight
- Loud banging/booming: May indicate dangerous delayed ignition
- Water pooling around furnace: Could be condensate drain or heat exchanger leak
Las Vegas Winter Reality:
While Las Vegas winters are mild (average lows 40-45°F), desert nights can drop to 30-35°F during cold snaps. Without heat, indoor temperatures can reach 50°F or lower, which is uncomfortable and potentially unsafe for vulnerable populations. Annual maintenance prevents 85% of winter heating failures.

Heating Repair vs Replacement in Las Vegas
Deciding whether to repair or replace your furnace depends on several factors. Here's a practical decision guide for Las Vegas homeowners:
REPAIR Makes Sense If:
- Furnace is under 10 years old
- Repair cost is less than $800
- Efficiency rating is 80% AFUE or higher
- System has been well-maintained annually
- Only one component needs replacement
- No plans to sell home in next 5 years
REPLACE if:
- Furnace is 15+ years old
- Repair cost exceeds 50% of replacement cost
- Efficiency below 80% AFUE (old unit)
- Heat exchanger cracked (carbon monoxide risk)
- Multiple components have failed in past 2 years
- Energy bills have increased significantly
The 50% Rule for Las Vegas:
If repair cost × remaining years (20 - current age) is greater than new furnace cost, replace. Example: $900 repair on 14-year-old furnace = $900 × 6 years = $5,400 total cost potential. New furnace costs $3,000-$5,000 with 20-year lifespan. Replacement is better value.
