When your furnace fails at midnight during a -20°C winter night, you don’t need a blog—you need help NOW. Emergency furnace repair situations demand immediate response, fast diagnosis, and expert solutions.
This guide covers everything about emergency furnace situations in Calgary: when to call 24/7 services, what constitutes a true emergency, how to stay safe during heating failure, temporary measures, and how to prevent future emergencies.
1. Is Your Furnace Emergency Really an Emergency?
Not all furnace problems require 24/7 emergency service. Understanding the difference saves money while ensuring you get help when truly needed.
True Emergency Situations (Call NOW)
No heat during freezing temperatures:
- Outside temperature below 0°C, furnace won’t heat
- Home temperature dropping below 15°C
- Pipes at risk of freezing
- This is an urgent situation requiring immediate response
Gas smell:
- Indicates possible gas leak
- Call 911 or emergency gas line service immediately
- Don’t use electrical switches or create flames
- Evacuate home if smell is strong
Carbon monoxide alarm triggered:
- indicates CO poisoning risk
- CALL 911 IMMEDIATELY
- Exit home immediately
- Don’t re-enter until cleared by emergency services
Yellow or flickering pilot light:
- Indicates incomplete combustion or dangerous gas production
- Turn furnace OFF
- Call emergency service
- Don’t use furnace until checked
Furnace making loud banging/popping sounds:
- May indicate delayed ignition (safety hazard)
- Turn furnace OFF
- Call professional immediately
Water leaking from furnace:
- Indicates condensation system problem
- Potential for electrical hazard or water damage
- Turn furnace OFF
- Call professional
Non-Emergency Repairs (Can Wait Until Business Hours)
Weak but present heat:
- If some heat is coming through, can usually wait until morning
- Use portable heater temporarily
- Get professional service scheduled
Unusual noises but heat still working:
- Schedule appointment for next business day
- Furnace still heating, lower risk
Occasional short cycling:
- If furnace cycles on/off but eventually reaches set temperature
- Can wait for morning service
2. Immediate Safety Precautions During Furnace Failure
If your furnace stops working, follow these steps BEFORE calling for repair.
Step 1: Verify It’s Actually OFF
Confirm furnace won’t restart:
- Check thermostat—is it set to HEAT?
- Verify furnace power switch is ON
- Check circuit breaker—is it tripped?
- If you find it’s just OFF, turn back ON and wait 15 minutes to see if it restarts
Step 2: Prevent Frozen Pipes
Immediately take action to prevent pipe freeze damage:
Open cabinet doors:
- Open doors under all sinks (kitchen, bathrooms)
- Allows warm air to reach pipes
- Critical in unheated basement areas
Drip faucets:
- Open faucets slightly in coldest areas
- Running water is much harder to freeze than static water
- Focus on second-floor bathrooms, exterior walls
- Even a small drip helps
Insulate exposed pipes:
- Use towels, blankets, or pipe insulation (if available)
- Wrap any exposed pipes in unheated areas
Keep interior doors open:
- Allow warm air to circulate throughout home
- Don’t seal off cold rooms
Temporarily close off cold rooms:
- Actually contradicts above—focus instead on protecting pipes
- Primary goal: keep water flowing or slightly warm
Step 3: Stay Safe During Shutdown
Health & safety priorities:
- Indoor temperature: Home will cool to outdoor temperature within 2–4 hours if furnace is completely OFF
- Hypothermia risk: Prolonged exposure to cold indoors is dangerous
- Make decision: Can you get professional help immediately, or do you need temporary heat source?
Temporary heating options (if furnace won’t start):
- Portable electric heater (keep 3+ feet from walls, furniture, curtains)
- Wood fireplace or stove (if available)
- Stay in one room with door closed to concentrate heat
- Layer clothing, use blankets
Where to go if home becomes unsafe:
- Friend or family member’s home
- Hotel or motel
- Emergency shelter (if truly homeless situation)
Step 4: Prevent Carbon Monoxide Poisoning
If CO alarm goes off:
- CALL 911 IMMEDIATELY
- Exit home immediately—don’t delay
- Don’t re-enter until emergency responders clear home
- Never use furnace again until professionally inspected
Never operate furnace if:
- Gas smell present
- Pilot light is yellow or flickering
- CO alarm has triggered
- Heat exchanger visibly cracked
- You suspect any safety issue

6. Emergency Furnace FAQs
Q1. My furnace stopped working at 2 AM in winter. Is it an emergency?
Answer: YES if:
- Outside temperature is below 0°C
- Home is cooling rapidly
- Pipes could freeze
- You have elderly, children, or health-vulnerable people
Call 24/7 emergency service immediately.
If furnace has other heat (fireplace, portable heater) and you can keep home above 15°C, you can wait until morning.
Q2. Should I try to repair my furnace during an emergency?
Answer: NO. Only DIY:
- Check thermostat batteries
- Verify power switch is ON
- Reset circuit breaker
- Replace air filter
- Open pipe access (under sinks)
Call professional for:
- Any component work
- Gas line issues
- Electrical problems
- Safety concerns
Q3. What’s the difference between emergency and regular furnace repair pricing?
Answer: Emergency costs more because:
Why surcharges exist:
- Service available 24/7 (requires on-call staff)
- Night/weekend work commands premium pay
- Response during extreme weather is riskier
- Limited availability increases demand
Typical surcharge: $100–$300 above normal rates
Example:
- Regular blower motor repair: $999
- Emergency blower motor repair: $1,199–$1,299
Q4. My furnace is making a loud noise—is it an emergency?
Answer: Depends on the noise:
Likely emergency:
- Loud bang when furnace starts (delayed ignition hazard)
- Gas smell accompanying noise
- Grinding or severe rattling
Can usually wait:
- Squealing (common, usually belt-related)
- Soft rattling or humming
- Occasional clicking
When unsure: Call and describe noise to dispatcher—they can advise
Q5. Can I use my gas fireplace instead of furnace during emergency?
Answer: Temporarily, yes.
Important considerations:
- Fireplace provides some heat but not whole-home heating
- Not sufficient for extended periods
- Still need to protect pipes
- Don’t rely on fireplace as solution—get furnace fixed
Safety:
- Ensure fireplace/stove is operating properly
- Verify chimney isn’t blocked
- Don’t leave fireplace unattended
