Furnace Tune-Up.
London Ontario.
$149. 12 Points.
Before the First Cold Night.
London Ontario's most thorough furnace tune-up — $149, TSSA-certified 12-point safety inspection. Heat exchanger inspection. Combustion analysis. CO safety check. Burner cleaning. Ignitor and flame sensor service. Eight more critical checks. Written inspection report. 150+ five-star reviews. BBB A+.
⚠️ Carbon monoxide risk: A cracked heat exchanger is the most common source of CO from gas furnaces. CO is colourless and odourless — detectable only with a combustion analyzer or CO detector. Hawana inspects every heat exchanger on every tune-up. This check alone is worth the cost of the visit.

The heat exchanger is the metal wall inside your furnace that separates combustion gases — including carbon monoxide (CO) — from the air that circulates through your home. When it cracks, CO can enter your living space.
- →Normal thermal stress over 15–25 years
- →Overheating from restricted airflow (clogged filter)
- →Short-cycling from an oversized furnace
- →Accelerated by running with a missing filter
- ✓Visual inspection of accessible heat exchanger surfaces
- ✓Combustion spillage test on furnaces 15+ years old
- ✓Combustion analysis — CO levels in flue gas measured
- ✓Finding documented in written inspection report
If a cracked heat exchanger is found: Hawana provides a written assessment with repair vs replacement options. The furnace must not be run until the heat exchanger is repaired or replaced — CO risk. This is never an arbitrary call — Hawana explains exactly what was found and what the options are. You decide.
The Hawana 12-Point
Furnace Tune-Up Checklist
All 12 points on every visit. TSSA-certified technician. Written report after every visit. Safety-first — the heat exchanger and combustion analysis are never skipped.
Visual inspection of heat exchanger for cracks, holes, and stress fractures. The most critical safety check on any gas furnace. On older systems, combustion spillage test also performed.
Calibrated combustion analyzer measures CO and CO2 in flue gas, excess air percentage, and flue temperature. Identifies unsafe combustion before symptoms develop. TSSA-certified technician required.
Burners removed and inspected for corrosion, debris, and uneven flame pattern. Cleaned if needed. Improper burner combustion produces excess CO and accelerates heat exchanger wear.
Hot surface ignitor inspected and tested. An ignitor nearing end of life is identified before it causes a no-heat failure. Replacement quoted on-site if weak — part typically on truck.
Flame sensor rod cleaned with fine steel wool to remove oxidation buildup. A dirty flame sensor causes nuisance lockouts — furnace starts and shuts off every few minutes. Quick preventative fix.
Inducer motor bearing checked for wear and noise. Airflow verified. A failing inducer bearing is detectable weeks before failure — a loud rattling or grinding during startup is the warning sign.
Pressure switch and rubber hoses inspected and tested. Blocked, cracked, or disconnected hoses are a common source of pressure switch faults — a quick $15 fix that prevents a service call in winter.
High-limit switch operation verified. A limit switch that trips repeatedly indicates overheating — usually a dirty filter or blocked register. Confirmed and the cause identified during the tune-up.
Gas pressure at the manifold measured against manufacturer specification. Gas valve operation confirmed. Incorrect gas pressure causes inefficient combustion and elevated CO production.
Blower motor and belt (if applicable) inspected for wear. Amperage draw measured. A failing blower motor reduces airflow, causing heat exchanger overheating and accelerated wear — detectable before failure.
Filter inspected and replaced if needed. Homeowner shown correct filter type, MERV rating, and replacement schedule. A clogged filter is the single most preventable cause of furnace overheating and heat exchanger damage.
Thermostat calibrated and operation confirmed. CO detector operation tested — a functioning CO detector is London Ontario homeowners' last line of defence against heat exchanger leaks. Written inspection report provided.
All 12 points completed on every visit by a TSSA-certified technician. Written report provided. Any repairs found are quoted before work begins. $149 flat — no hidden fees.
Best Time to Book Your
Furnace Tune-Up in London Ontario
A furnace failure in October is inconvenient. In January at −20°C it is an emergency. When you book determines which scenario you face.
Best time. Fast scheduling. Furnace inspected before first cold night. Any issues repaired on your timeline. Most slots available. Heat exchanger findings don't become emergencies.
Still good before deep winter. Some scheduling pressure as other homeowners book. Last recommended window for a truly pre-season inspection.
Peak heating season. Scheduling difficult. If a problem is found, emergency repair needed immediately with no heat available. Avoid this window — book before December.
Furnace already broken? Call for emergency repair — $175 flat, 24/7, zero surcharge, 1–2 hour response. Once repaired, schedule fall tune-up for next season.
The $149 tune-up math: A worn inducer bearing found in October is a $400 repair on your schedule. The same bearing failing at midnight in January is a $175 emergency call + $400 repair + the stress of no heat. Most years, the tune-up pays for itself. Some years it protects you from far worse.

What a $149 Tune-Up Prevents
in a London Ontario Winter
A weakening ignitor is detectable during inspection. Replaced during a tune-up: ~$60–80 in parts. The same ignitor failing at 2 a.m. in January: $175 emergency call + $60–80 part + no heat overnight. Annual inspection wins every time.
Early inducer motor bearing wear produces a faint rattling during startup — caught during inspection. Bearing replacement: ~$300–400 on your schedule. The bearing failing in December: $175 emergency + $400 repair + multiple cold nights while waiting for parts.
Flame sensor cleaning takes 5 minutes during a tune-up. A dirty sensor causing repeated nuisance shutdowns in January: homeowner calls thinking the furnace is broken. Emergency call, 5-minute cleaning, $175 service call fee. Cleaned in October during tune-up: free.
Annual combustion analysis tracks heat exchanger condition over time. Early-stage fatigue identified means replacement can be planned — new furnace from $3,400 on your schedule. Heat exchanger failure discovered mid-winter means emergency replacement, no options, maximum urgency. Annual inspection gives you control.

What Happens When You Book
a Hawana Furnace Tune-Up
"Booked the fall tune-up in October. Abdullah found early wear on the inducer motor bearing — said it would fail within a few weeks under heating load. Replaced it the same day. Furnace ran perfectly all winter. That $400 repair done in October saved me a $175 emergency call in January with no heat."
"22-year-old furnace. Abdullah did the combustion analysis and found elevated CO levels in the flue — traced to a small crack in the secondary heat exchanger. He showed me exactly what he found, explained the risk clearly, and gave me options without pressure. We replaced the furnace. That tune-up may have saved lives."
"Signed up for the Basic Care Plan — $149 covers furnace and AC both. October furnace visit found a dirty flame sensor causing intermittent lockouts I hadn't noticed yet. Cleaned in five minutes. Written report in hand for warranty. The plan discount has already paid back 30% of the annual cost. Excellent value."
