Furnace Repair & Maintenance
London Ontario
Hawana HVAC Solutions provides furnace repair and annual maintenance in London Ontario. $175 diagnostic at any hour, any day — zero after-hours surcharge. Enercare charges $129 on weekends and statutory holidays just for the diagnostic visit, before any repair work begins. Emergency HVAC calls in Ontario commonly add $40 to $90 per hour outside business hours. Hawana: $175 regardless. TSSA certified gas technician. BBB A+. 137 five-star reviews. All makes and models. No rental push during repair visits — if replacement is recommended, Hawana quotes outright purchase only, no rental enrollment, no monthly commitment. London's housing stock generates three distinct repair scenarios: 2am January no-heat calls where the zero surcharge removes the hesitation to call immediately; Old South, Wortley, and Woodfield heritage homes that benefit most from annual maintenance because aging equipment accumulates problems routine cleaning catches before they become emergencies; and Byron, Westmount, and Old South century homes where honest heat exchanger diagnosis and the 50 percent rule replacement quote are more valuable than a repair that delays the inevitable. Annual maintenance from $149, no monthly subscription, no auto-renewal.

Furnace Repair by Symptom — London Ontario
What the symptom tells you, what the typical repair costs, and when the 50 percent rule applies. All diagnosed at the same $175 visit.
Furnace Won't Light or Cycles On and Off
Most likely cause: Failed ignitor or dirty flame sensor. The ignitor glows but no flame appears (failed ignitor, $150–$350), or the furnace lights briefly then shuts off (dirty flame sensor, $150–$250). Both are the most common London furnace repair calls. Well within the 50 percent threshold on any age of furnace — repair is almost always the right call unless the furnace is 15-plus years old and has multiple issues accumulating.
Furnace Runs but No Air — or Weak Airflow
Most likely cause: Blower motor failure or failed capacitor. The furnace fires but the blower doesn't move air (motor failure, $400–$600) or starts slowly and runs intermittently (capacitor, $150–$300). London's older homes — Old South, Woodfield, Wortley — have original blower motors that are now 20-plus years old. At $400–$600 for a motor replacement, the 50 percent rule calculation depends on furnace age and overall condition. Both options quoted at the same visit.
Rattling, Banging, or Metallic Scraping
Most likely cause: Loose panels (minor), blower wheel debris (cleaning), or cracked heat exchanger (replacement required). Banging on startup is delayed ignition — a safety issue. Metallic scraping means the blower wheel has contacted the housing. A cracked heat exchanger requires furnace replacement regardless of age or cost — the carbon monoxide risk is non-negotiable. Sike T.'s Byron century home: rattling led to heat exchanger crack diagnosis and honest replacement recommendation. No attempt to repair and bill first.

Abdullah Ghzail — Lead HVAC Technician & Founder
Abdullah repairs and services furnaces throughout London Ontario — $175 at any hour with zero after-hours surcharge, so a 2am January emergency on Royal York Road carries the same cost as an October maintenance booking in Old South. No rental push on repair visits: if a London furnace needs replacing, the honest assessment and the 50 percent rule quote are provided at the same diagnostic visit, outright options only. Annual maintenance from $149 with no monthly plan and no auto-renewal — London's heritage housing stock in Old South, Wortley, Woodfield, and Byron benefits more from annual maintenance than newer builds because aging equipment accumulates problems that an October cleaning catches before a January emergency call. TSSA certified. BBB A+. 137 five-star reviews. In business since 2018.
London Ontario Furnace Repair Reviews
137 five-star Google reviews — 2am emergency no surcharge, Old South annual maintenance catching failure, and Byron century home honest heat exchanger diagnosis all covered. Read all ↗
"Furnace failed at 2am Saturday, January — Royal York Road, North London. House at 14 degrees. Enercare publishes $129 weekend diagnostic. Hawana: $175 any hour, zero surcharge. Called, Abdullah arrived 3:15am. Ignitor replacement. Running by 4am. No surcharge on top. No rental enrollment pushed. Invoice matched exactly. When your house is 14 degrees at 2am in January, you don't need a calculation about what it costs to call. Hawana made that calculation unnecessary."
"Annual maintenance at our 1940s Old South home. Third year doing this. This October: flame sensor heavily coated — another season without cleaning and we'd have had a mid-January no-heat call instead of an October maintenance visit. The difference in cost and stress is substantial. $149 for the year, no monthly plan, no auto-renewal. Heat exchanger checked visually — clear this year. No pressure to replace anything that doesn't need it."
"Rattling furnace at our Byron century home — 19 years old. Diagnosed as hairline heat exchanger crack. Carbon monoxide risk. Abdullah was direct: repair would hit or exceed the 50% threshold against a new furnace, replacement is the right call. Quoted both. Replacement was obvious. New Goodman installed next morning. No attempt to repair and bill first. No rental enrollment. Invoice matched. The honest diagnosis and the clear 50% explanation were exactly what I needed."
