24/7 Emergency Furnace Repair in Greater Sudbury
Furnaces here never die at lunch — they quit at 11:30 PM in a cold snap, right when the house is already losing heat. That’s when most homeowners call us — and that’s why our emergency team is always on standby.
Why Furnace Breakdowns Happen at Night
Furnaces work the hardest overnight when temperatures drop fast. That’s when weak parts finally give out:
- ignitors cool down and fail
- dirty flame sensors stop reading the flame
- safety switches trip from overheating
- older blowers can’t keep up
- burners struggle when the house hits deep-cold
Night is when problems show up — not when it’s warm outside.
How Our Emergency Team Responds
You don’t get a voicemail. You don’t wait until morning.
Here’s how it works:
- your call is answered live, 24/7
- dispatcher asks a few quick questions to see how urgent it is
- “no heat” cases jump to the top of the list
- a tech is notified instantly and assigned a priority
- you get an ETA right away
No guessing, no “we’ll see tomorrow,” no runaround.
How Fast the Technician Arrives
Most no-heat calls are handled within 2–4 hours, depending on weather and time of night.
During deep freezes (–20°C and colder), we run a No-Heat Protocol:
- techs stay on-call
- routes are optimized
- high-risk homes (kids, seniors, basements, townhomes) go first
If the house is actively dropping below safe temperature, we try to get there as fast as possible.
What You Should Do Before We Arrive
Nothing complicated. Just the basics:
- check the thermostat setting
- look at the filter (don’t remove anything — just check if it’s plugged)
- listen for unusual sounds (helps the tech diagnose faster)
- if you smell gas — shut the furnace off immediately
- if the furnace is cycling hard, don’t keep restarting it
- keep windows and doors closed to hold heat
That’s it. Don’t open panels, don’t try YouTube fixes — just keep the house warm until we get there.
Risks You Shouldn’t Ignore
A dead furnace in Greater Sudbury is more than discomfort:
- frozen pipes → thousands in water damage
- gas issues → serious safety hazard
- CO buildup if something failed in combustion
- overheating if the system keeps trying to restart
- total lockout → harder, more expensive repairs
If the house starts cooling fast — don’t wait. Every hour matters.
No Heat Right Now?
Call anytime — day, night, weekend, holiday. We’re always open, and we treat every no-heat call like it’s our own home.
Furnace Issues in Greater Sudbury – Common Real Situations
When Greater Sudbury hits real winter, these are the furnace calls we get every single day:
Cold rooms while the furnace runs non-stop
Some rooms warm up, others don’t. Heat just isn’t moving. Almost always restricted ducts, weak blower, or the furnace is undersized for the house.
Main floor warm, basement cold
Classic Greater Sudbury problem. Living area is fine, basement stays icy. Usually bad duct design, closed or stuck dampers, or years of neglected maintenance.
Furnace short-cycling
Furnace only runs short bursts — on for a few minutes, off, back on. Typically a dirty flame sensor, blocked filter, overheating, or the thermostat misbehaving. It’s stressing the system and needs fixing fast.
Gas bills suddenly way higher
Same thermostat setting, same habits, but the bill jumps. Dirty burners, blocked airflow, or an aging furnace losing efficiency — all make it burn extra gas.
No heat when it’s -30°C outside
Furnace dies overnight. Ignition failure, failed control board, or a safety limit tripped. House drops temperature quick. This one needs a licensed gas tech right away.
Sound familiar? Book a check now — before the deep freeze hits and we’re slammed. Small fix today beats a frozen house tomorrow.
Common Causes of Furnace Problems
Greater Sudbury winters beat furnaces up. Here’s what we actually fix every day:
Some rooms warm, some cold. Clogged ducts, stuck dampers, tired blower, or the furnace just isn’t big enough for the house.
Never cycles off. Ducts leaking air, weak insulation, dirty filter, or the unit’s too old and worn out to hold temperature.
Dirty burners, restricted airflow, failing blower, or the furnace just getting old and inefficient.
On for 3-5 minutes, off, repeat. Dirty sensor, blocked filter, overheating, misreading thermostat.
Bang, rattle, squeal, grind. Worn bearings, loose parts, bad inducer, or ducts popping. Gets worse if ignored.
Burners not lighting right, low gas pressure, weak blower, or a safety tripping.
Ignition dead, flame sensor failed, control board gone, or safety switch killing it.
Dusty smell once a year is fine. Anything else — shut it off and call now.
Dirty burners. Burns inefficient and can be unsafe. Needs cleaning and tuning.
Serious. Can leak exhaust into the house. Soot, CO alarm, or constant lockouts are the clues. Furnace stays off until fixed.

What We Check During a Furnace Inspection
A proper furnace check isn’t a “quick look.” We go through the parts that actually fail in Greater Sudbury winters — the things that keep your heat running when it’s -25°C outside.
We check how well air moves through the ducts. Poor airflow means cold rooms, overheating, and short-cycling.
Weak motor = weak heat. We check bearings, speed, noise, and any signs it’s about to fail.
Burners get dirty fast. We make sure they light clean, burn steady, and don’t produce a lazy yellow flame.
Most no-heat calls start here. We check the ignitor strength and clean or replace sensors that don’t read the flame correctly.
Cracks or leaks are serious. We inspect for hot spots, soot, and any sign combustion gases aren’t staying where they belong.
This guy pulls exhaust out. If the inducer’s weak or making noise, the system can’t operate safely.
We check that the thermostat is sending the right signals — no bad readings, no weak batteries, no loose connections.
A plugged filter is the quickest way to wreck a furnace. We check filter condition and make sure the home has enough return air.
Frozen or clogged drains shut furnaces down. We clear the trap and make sure water is draining the way it should.
We test the switches that keep your furnace safe — rollout, high-limit, pressure switches. If one’s tripping, we find out why.
We check incoming pressure, regulator function, and make sure there are no leaks or loose fittings.
Proper exhaust flow is critical. We check the vent pipe, joints, slope, and test for carbon monoxide around the unit.
Furnace Maintenance
When you live in Greater Sudbury, maintenance isn’t “nice to have.” It’s what keeps a furnace from dying when the deep-cold hits, the air dries out, and the ducts fill with dust. One good tune-up a year stops most of the winter breakdowns we get called for.
Seasonal Tune-Ups
A proper tune-up is not a quick vacuum and out the door. It’s checking the parts that actually fail when it hits –25°C:
- burners cleaned and tested
- flame sensor cleaned
- ignitor checked for strength
- blower tested for speed and noise
- heat exchanger inspected
- drain lines cleared (for high-efficiency furnaces)
- filters checked
- thermostat calibration checked
- safety switches tested
- gas pressure verified
That’s what keeps a furnace running steady when winter starts hammering.
What’s Included in a Tune-Up
A real furnace tune-up includes:
- full cleaning of burners, flame sensor and cabinet
- blower motor inspection (amp draw, bearings, movement)
- checking heat exchanger for cracks or hot spots
- checking inducer motor operation
- checking and clearing condensate trap
- checking gas pressure
- tightening electrical connections
- confirming proper venting and airflow
- verifying ignition and flame pattern
- checking filter and return airflow
- thermostat signal testing
No “spray and pray,” no “15-minute visits.” A proper tune-up takes time because it actually prevents failures.
Why Tune-Ups Are Cheaper Than Repair
Winter repairs are expensive because everything runs harder and parts fail faster.
A tune-up prevents the big-ticket problems:
- failed blowers ($350–$900)
- dead ignitors ($150–$300)
- cracked heat exchangers (unit replacement)
- control board failures ($350–$700)
- short-cycling that burns the furnace out
$120–$180 a year is cheaper than a $500+ fix in –20°C cold.
How Long a Furnace Lasts With Proper Maintenance
Average furnace lifespan:
- Without maintenance: 10–12 years
- With yearly maintenance: 15–20+ years
High-efficiency units especially need maintenance because:
- drain lines clog faster
- sensors foul quicker
- burners get dirtier
- airflow restrictions cause early failures
Most “dead at 12 years” furnaces we replace were never serviced properly.
Maintenance Advice That Actually Helps
This climate is tough on furnaces because:
- winter temps swing from –5°C to –30°C overnight
- air is extremely dry — dries out bearings and belts
- homes pull in construction and city dust
- furnaces run long cycles during cold snaps
- high-efficiency units freeze at the drain lines if neglected
Real advice:
- change filters every 1–2 months in winter
- get a tune-up every fall
- keep snow away from intake and exhaust pipes
- don’t close too many vents — furnaces need airflow
- check the drain trap during cold spells
