You are not paying for a sales pitch. You are paying for 20+ years on gas furnaces, an honest diagnosis, and the repair done right the first time. We do not sell installs, so there is no incentive to push a $4,000 replacement. Most furnaces have a $150 to $400 fix in them. We find it.
Most Tillsonburg no-heat calls fall into a handful of failure patterns. Plain-English descriptions below so you know what you are dealing with before the tech arrives.
Ignitor, gas valve, control board, pressure switch — we find the culprit fast. No-heat calls are highest priority.
Furnace fires up and shuts off before the house warms. Usually a limit switch, flame sensor, or heat exchanger issue.
Fan runs constantly even when the burners are off. Often a relay or control board fault.
Furnace tries to light, fails, locks out. These are common wear parts — a straightforward repair for a licensed tech.
Pressure switch won't close; inducer motor worn. Furnace refuses to start the ignition sequence.
Furnace calls for heat but the burners stay off. Requires a licensed gas tech — that's us.
Your furnace is flashing a fault code and won't run. We read it, trace the fault, fix it.
Banging, squealing, rumbling. Could be a blower bearing, loose heat exchanger panel, or delayed ignition.
Don't see your symptom? Describe it in the booking form — we'll figure it out on site.
Book a Furnace DiagnosticCall most HVAC companies and your invoice covers a sales lead opportunity, a service-plan pitch, and a technician working under an install quota. Call us and you are paying for diagnostic skill, parts, and labor. Nothing else.
Every call starts with a diagnostic. You see the fault, you see the quote, and nothing gets touched without your sign-off.
We do not run a furnace, AC, boiler, or water heater install department. There is no upsell incentive, no replacement quota, no commission on a new system. (The exception: we do sell and install indoor air quality add-ons — humidifiers, HRVs, UV, EACs — that connect to your existing system.)
TSSA-registered G2 gas technician. Two decades of diagnostic work across every brand. Most failures are common patterns and we have seen them all.

No heat in a January cold snap is not a "next available Tuesday" problem. Our phone line and online booking answer 24/7 — call or book any hour and the system locks in the next available window, and genuine furnace emergencies in Tillsonburg get same-day priority whenever the schedule allows. Regular service hours are Monday to Saturday, 8 a.m. to 6 p.m. One important exception: if you smell gas or a CO alarm is sounding, that is life-safety — call 911 and Enbridge (1-866-763-5427) first, then use the red Emergency button at the top of this page.

A furnace under 15 years old with a failed igniter, sensor, switch, or even a control board is almost always worth fixing: the repair is a fraction of a $6,000-8,000 replacement. Past 18-20 years, or with a cracked heat exchanger, replacement math starts to win. We do not sell or install furnaces, so when we tell you which side of that line you are on, there is no commission behind the answer. If it is genuinely done, we say so and point you to a trusted local installer.
