Furnace Repair
When your furnace stops working in February, you need someone who can be there fast and figure out what's actually wrong — not someone who's going to drop a part-replacement quote on you the moment they walk in. We diagnose furnace problems across Halton Hills properly, explain what we found in plain language, and only recommend the work that actually solves the problem.
Our technicians are TSSA-certified gas fitters with years of experience on the brands you'll find in Georgetown homes — Lennox, Carrier, Trane, Goodman, York, Rheem, and the rest. Most repair calls get diagnosed and fixed in a single visit. When a unit's truly at end-of-life, we'll tell you that too — with the math to back it up.
When you need furnace repair
Some furnace symptoms can wait a day. Others mean a real safety issue. Here's what to watch for:
- No heat at all. Thermostat is calling for heat, but the furnace isn't responding — could be a tripped flame sensor, a control board issue, a thermostat fault, or a gas supply problem. Always worth a same-day call in winter.
- Furnace short-cycling (turning on and off every few minutes). Usually means a clogged filter, a flame sensor issue, an oversized furnace, or a flue restriction. Wears equipment out fast — fix it sooner rather than later.
- Furnace running but blowing cold air. Pilot/ignition problem, gas valve issue, or limit switch tripped. Sometimes a quick fix.
- Strange noises — banging on startup (delayed ignition, often safety concern), squealing (blower bearing or belt), grinding (motor failing), repeated clicking (relay/control board).
- Burning smell that doesn't go away in the first 10 minutes of a season. Could be wiring or a stuck blower wheel — turn the furnace off and call.
- A rotten egg or sulfur smell. This is a gas leak. Leave the house, call your gas utility (Enbridge: 1-866-763-5427) BEFORE calling us. Your safety first.
- Carbon monoxide alarm sounding. Evacuate, call 911 or Enbridge, then us. Don't re-enter until professionally cleared.
How a furnace repair call goes with us
- 01
Diagnostic visit
We arrive in the booked window, walk you through what we're seeing, and run through the likely causes systematically — not jumping to the most expensive part first. Most problems are diagnosed in 20–45 minutes.
- 02
Honest assessment
We show you what we found and what it'll cost to fix. If your furnace is over 15 years old and the repair is more than 50% of replacement cost, we'll have an honest conversation about whether replacement is the smarter long-term move — including any rebate eligibility.
- 03
Repair (when it makes sense)
Most repairs are completed in the same visit — flame sensors, capacitors, igniters, thermocouples, control boards, blower motors. We carry common parts on the truck for the brands prevalent in Halton Hills.
- 04
Verification & cleanup
Before we leave, we cycle the furnace through a full heating cycle to confirm the fix held, check combustion safety, clean up the work area, and walk you through what was done.
Furnaces we service
We work on every major brand sold in Ontario — current models and the older units still going strong in Delrex bungalows and Park District century homes alike:
What furnace repair costs in Halton Hills
Most diagnostic visits run $120–$160 and we waive the diagnostic fee if you proceed with the recommended repair. Common single-component repairs (flame sensor, capacitor, igniter, thermocouple, contactor) typically land in the $250–$550 range parts and labour. Bigger jobs — blower motor replacement, control board, gas valve — usually run $500–$1,400.
We quote the repair before any work starts. No hidden fees, no surprise add-ons. If a major component fails on a furnace older than 12–15 years, we'll lay out the math on repair-vs-replace honestly so you can decide.
Furnace Repair questions
How quickly can you respond to a no-heat call in winter?
During business hours we aim to be on-site within 4 hours for no-heat emergencies. We maintain 24/7 emergency dispatch for after-hours calls — slightly higher rates apply outside business hours, but for genuine no-heat in February it's worth it.
Should I repair my old furnace or replace it?
Two rules of thumb. First, age: if the furnace is over 15 years old and the repair is more than 50% of replacement cost, replacement usually wins on a 5-year cost basis. Second, efficiency: a 1990s furnace is around 80% AFUE — every $100 of natural gas you burn, $20 goes up the chimney. A modern 96% AFUE furnace cuts that to $4. With current Ontario rebate stacking ($1,500–$5,000+ available depending on equipment), the payback period on replacement has shortened considerably.
Why is my furnace short-cycling?
Short-cycling — the furnace turning on and off every few minutes — has a handful of common causes. Most often: a dirty filter restricting airflow and tripping the limit switch. Second most common: an oversized furnace (which is unfortunately the default in many Halton Hills homes from contractors who upsize to be safe). Third: a faulty flame sensor causing premature shutoff. Fourth: a flue restriction. We'll diagnose it properly before throwing parts at the problem.
What does that 'rotten egg' smell mean?
That's mercaptan — the additive natural gas suppliers add to make leaks detectable. If you smell it, leave the house immediately, don't operate light switches or anything electrical, and call Enbridge Gas at 1-866-763-5427 from outside. We can come out after the gas company has cleared the leak.
Do you service older furnaces from the 80s and 90s?
Yes. We service every era of residential furnace, including the older mid-efficiency and standing-pilot units still running in many older Halton Hills homes. We'll always be honest with you if a unit is past sensible repair, but we won't refuse to work on something just because it's old.
Will my warranty be voided if you service a furnace from another installer?
No. Manufacturer warranties travel with the equipment, not the installer. As long as the work is performed by a TSSA-registered contractor (which we are), the warranty stays valid. We can also register your equipment with the manufacturer if the original installer didn't.
Do you carry parts for common repairs on the truck?
Yes. Capacitors, flame sensors, igniters, thermocouples, contactors, common control boards, and most universal blower motor sizes. About 80% of our repair calls are completed in a single visit. For unusual parts (specific control boards on older units, OEM-only components), we order and return — usually within 1–3 business days.
