Furnace Problems We Repair Same-Day in St. Thomas
Parts stocked for all major brands. Most St. Thomas furnace repairs are completed same-visit without waiting for parts.
No Heat — Furnace Won't Start
The most common St. Thomas furnace call. Usually a failed hot surface igniter. St. Thomas homes built in the 1980s and 1990s with mid-efficiency furnaces are especially prone to igniter failure. Quick diagnosis, part on the truck, repaired in under an hour.
Furnace Starts Then Shuts Off
Burner lights for 5–20 seconds then shuts down, repeatedly. Almost always a dirty flame sensor — the sensor tells the control board no flame was detected even though the burner is lit. A 30-minute clean or quick replacement fixes it same-visit.
Blower Running but No Heat
Fan runs but no warm air. Usually a failed igniter, flame sensor, or a tripped high-limit switch from a clogged filter. Check and replace your air filter first. If the problem continues call for diagnosis — the fix is often simpler and cheaper than expected.
Water Leaking from Furnace
Water pooling near your furnace in St. Thomas is almost always a blocked condensate drain — very common in St. Thomas homes where drain lines run through unheated spaces near exterior walls and freeze in winter. Cleared same-visit in most cases.
Loud Banging, Rattling, or Grinding
Banging at startup is delayed ignition — gas builds up before lighting. Shut off the furnace immediately and call us. Rattling often means a loose panel or failing blower. Grinding indicates a worn bearing. Don't ignore these — minor repairs become major if left.
Propane Furnace Repair — Elgin County
Rural properties east and west of St. Thomas on Elgin County roads often use propane rather than natural gas. Propane furnace repair requires specific expertise. Hawana services propane furnaces in Shedden, Springfield, Dutton, and all rural Elgin County properties.
Repair or Replace? Honest Advice for St. Thomas Homeowners
We tell you when repair makes sense — and when you are throwing money at a system that should be replaced.
Repair Makes Sense When...
The furnace is under 12 years old, the repair costs less than 30% of replacement value, it is a first-time failure of a single component, and the heat exchanger is intact with no cracks.
Replace Makes Sense When...
The furnace is over 15–20 years old, repair cost exceeds 50% of replacement value, there is a cracked heat exchanger, it has had multiple failures in the past 2 years, or it is running at 65–70% efficiency costing you significantly more in gas bills.
The Math for St. Thomas Homes
Many St. Thomas homes have 1990s furnaces running at 65–70% AFUE. A new 96% AFUE unit cuts gas waste by more than half. At current Enbridge gas rates in Elgin County, most St. Thomas homeowners recover the replacement cost in 5–7 years through energy savings.
Our Guarantee
We never recommend replacement when repair is the right financial decision. We never recommend repair when a failing 20-year-old system is going to keep breaking down every season. Our reputation depends on honest advice — not on which option earns us more today.
Always Replace — No Exceptions
A cracked heat exchanger is never repairable on a system over 12 years old — replacement is the only safe answer. Carbon monoxide leaks through a cracked exchanger are a serious life-safety risk. We will never advise you to continue operating a furnace with a confirmed cracked heat exchanger.
Replacement Benefits in St. Thomas
Enbridge rebates up to $600. Canada Greener Homes grants up to $5,000 for heat pumps. New high-efficiency installation from $3,400. View furnace installation →

"Called Hawana for furnace repair in our downtown St. Thomas home near Talbot Street. Technician arrived same afternoon, diagnosed a dirty flame sensor, cleaned it, and the furnace has been running perfectly since. Fast, honest, and fair pricing. No hidden charges."
"Our furnace in north St. Thomas stopped working on a Saturday morning. Hawana arrived within 2 hours, replaced a failed blower motor the same visit. Did not charge extra for the weekend — same price as a weekday call. That alone sets them apart from every other HVAC company in St. Thomas."
"Hawana repaired our propane furnace at our rural property east of St. Thomas. Not many HVAC companies know propane systems well but Abdullah diagnosed the problem quickly — a faulty gas valve — ordered the part and returned next day to complete the repair. Professional, honest, and knowledgeable."
