No heat, strange noises or a furnace that won’t stay on? O2 HVAC’s licensed gas technicians fix all makes and models across Abbotsford, day or night, and tell you upfront what the repair will cost.
Most furnace breakdowns in Abbotsford happen on the coldest nights of the year, when Arctic outflow winds push temperatures well below freezing and your furnace runs almost nonstop. In January 2024 the city dropped to −15.4°C, and that’s exactly when worn igniters, dirty flame sensors and tired blower motors give out.
O2 HVAC provides furnace repair services across Abbotsford for gas, high-efficiency and older mid-efficiency furnaces. Every technician is licensed to work on gas appliances in BC, every repair starts with a full diagnosis, and you approve the price before any work begins.
Furnaces don’t break down on a schedule, so we don’t work on one. Call 604-619-0202 any time and a technician will talk you through what’s happening, tell you whether it’s safe to wait, and book the earliest visit. For no-heat calls with young children, seniors or someone unwell at home, we prioritise emergency furnace repair and aim to have you warm the same day.
Our vans carry the parts that fail most often (igniters, flame sensors, pressure switches, capacitors and common control boards), so most repairs are finished in a single visit.
Call us if you notice any of these:
The blower runs, but the burners never light or shut off after a few seconds.
The furnace turns on and off every few minutes instead of running full cycles.
Banging when the burners light, squealing from the blower, or rattling from the cabinet.
A healthy gas flame is steady and blue.
High-efficiency furnaces make condensate, but it should drain away, not pool on the floor.
A dirty or struggling furnace burns more gas for the same heat.
Often a blower, duct or filter problem rather than the furnace itself.
Most furnaces show a fault code; note the pattern before you call.
These are the repairs our technicians make most often, and why they happen here.
Igniters crack after years of heating and cooling, and they often fail on the first cold night of the season.
A thin coat of residue stops the sensor from proving the flame, so the furnace lights and then shuts off. Cleaning or replacing it is a quick fix.
In garages and crawl spaces, high-efficiency furnace drain lines can freeze during an outflow. The furnace then shuts down to protect itself.
The intake and exhaust pipes on the side of the house can ice up or get buried in snow, which trips the pressure switch.
Usually caused by a clogged filter or closed vents that make the furnace overheat.
The burners light, but little air comes out of the vents, or the motor hums without starting.
The furnace hums or clicks but never reaches ignition.
Power surges during winter storms can damage boards, and older thermostats can lose their calibration.
A few simple checks can save you a service call:
Make sure it’s set to Heat, the temperature is above room temperature, and the batteries aren’t dead.
A clogged filter can trip the high-limit switch. Replace it if you can’t see light through it.
Check that the furnace switch (it looks like a light switch near the unit) is on and the breaker hasn’t tripped.
After snow or a hard frost, clear the white PVC pipes on the side of your house.
The blower compartment door must be fully closed, or a safety switch keeps the furnace off.
Still no heat? Don’t keep resetting the furnace. Repeated restarts can hide a safety problem. Call us instead.
Most furnace emergencies start as small problems that a yearly visit would catch. A furnace inspection in Abbotsford from O2 includes:
A furnace cleaning and tune-up takes about an hour for most homes. We’ll give you a written report and flag anything that’s wearing out before it fails in the middle of winter.
A repair is usually the right call for a furnace under 12 years old. Past 15 years, it’s worth weighing up a replacement, especially if the repair is a major part like a heat exchanger or control board.
A simple rule of thumb: multiply the furnace’s age by the repair cost. If the result is over 5,000, replacement usually makes more sense.
There’s another reason to plan ahead. If your gas furnace is 15 years or older, replacing it with a dual fuel system can qualify for FortisBC’s rebate. A rushed like-for-like swap in January usually doesn’t. Either way, we’ll put the repair quote next to the cost of furnace installation or a dual fuel system, so you can compare.
Once the gas is shut off and the leak is found, we can repair the furnace and test it safely. Every home with a gas furnace should also have a working carbon monoxide alarm on each floor.
Every quote starts with a diagnostic visit. Here are typical prices so you can plan:
After-hours and holiday calls may carry a surcharge [O2 to confirm]. You’ll always get the price before we start.

A standard furnace inspection and tune-up takes about 60 to 90 minutes. A repair visit usually takes one to two hours, depending on the part.
This is called short cycling. Common causes are a dirty filter, a dirty flame sensor, an oversized furnace or a thermostat in the wrong spot. A technician can find the cause in one visit.
High-efficiency furnaces produce condensate that drains away through a small line. If that line is blocked, cracked or frozen, water pools under the furnace. It’s usually a simple fix, but leave it too long and it can damage the furnace and your floor.
A dusty smell for the first few minutes of the season is normal as dust burns off the heat exchanger. A strong electrical or burning-plastic smell is not. Turn the furnace off and call us.
Yes. We repair and service all major brands, including Lennox, Carrier, Goodman, Trane, Bryant and Rheem, plus older furnaces many companies won’t touch.
Most repairs don’t need a permit, but any work on the gas supply must be done by a licensed gas fitter. Replacing a furnace or changing gas piping needs a Technical Safety BC gas permit, which we handle for you.
