A homeowner in Long Branch called us on a Sunday morning in January. Their furnace had stopped working overnight and the temperature inside had already dropped to 15 degrees. We had a technician there within a few hours. The issue turned out to be a cracked igniter — a common failure point on furnaces that age past ten years. We had the part on the truck, made the repair, and the house was warming up before noon. No one should spend a winter Sunday without heat in South Etobicoke. Furnace problems never seem to happen at a convenient time. When yours stops working, you need someone who shows up quickly, diagnoses accurately, and fixes it properly the first time.
Diagnose Accurately, Fix It Right
Furnace problems never seem to happen at a convenient time. When yours stops working, you need someone who shows up quickly, diagnoses accurately, and fixes it properly the first time. That's what we do.
Every service call starts with a full diagnostic. We inspect the heat exchanger, burner assembly, ignition system, flame sensor, blower motor, gas valve, safety controls, and flue before recommending any repair. Once we know exactly what's wrong, we explain it clearly and give you an upfront price before touching anything.
Common Furnace Problems We Repair
From complete breakdowns to subtle performance issues, our technicians are trained to diagnose and repair the full range of furnace problems.
No Heat at All
The most urgent situation. Common causes include a failed igniter, a faulty flame sensor, a tripped high-limit switch, or a gas valve issue. Each has a different fix — accurate diagnosis is the starting point.
Furnace Short Cycling
A furnace that turns on and off repeatedly without completing a full heating cycle is wasting energy and putting wear on components. Overheating due to restricted airflow, a faulty flame sensor, or a malfunctioning thermostat are the usual culprits.
Blower Running, No Heat
The fan is moving air but it isn't warm. This typically points to an ignition failure, a gas supply issue, or a tripped safety switch that needs investigation before reset.
Yellow Flame or Unusual Noises
A healthy furnace flame is blue. Yellow or orange flames indicate incomplete combustion and potential carbon monoxide — a safety issue that should be addressed immediately. Banging, screeching, or rattling noises all point to specific mechanical issues worth diagnosing promptly.
How We Diagnose & Repair Furnaces
We stock common furnace parts on our service vehicles, so most repairs are completed on the same visit. After the repair, we run the furnace through a complete heating cycle and verify safe operation before we leave.
Igniter & Flame Sensor
Replacement of failed igniters and dirty or failing flame sensors — among the most common furnace repairs we perform.
Heat Exchanger Inspection
Thorough inspection for cracks or damage. A cracked heat exchanger is a safety issue that requires immediate attention.
Blower Motor & Capacitor
Diagnosis and replacement of blower motors and capacitors that are causing airflow issues or complete blower failure.
Gas Valve & Control Board
Diagnostics and replacement of gas valves and control boards — more involved repairs that we handle with precision.
Limit Switches & Safety Controls
Replacement of high-limit switches, pressure switches, rollout switches, and other safety controls.
Thermostat & Wiring
Diagnosis of thermostat communication issues and wiring faults that cause erratic or no furnace operation.
What Customers Say About Our Furnace Repair

Called Beyond HVAC on a Sunday morning when our furnace stopped working. Technician was there within a few hours, diagnosed the problem quickly, had the part on the truck, and we had heat again before noon. Exactly what you need in that situation.

Our furnace was short cycling and we were worried about a big repair bill. The technician found a dirty flame sensor, cleaned it, tested everything, and the bill was very reasonable. Honest, professional, and fast.

Beyond HVAC found a crack in our heat exchanger during a repair call. They explained exactly what it meant, showed us the issue, and gave us clear options without any pressure. We ended up replacing the furnace and couldn't be happier with how they handled it.
Repair vs. Replace
When Repair Makes Sense
If your furnace is under ten years old and facing a straightforward repair, fixing it almost always makes sense. We'll give you a firm price and get it done on the same visit in most cases.
When Replacement Is Smarter
For systems approaching 15 to 20 years old or facing a major component failure like a cracked heat exchanger, replacement is often the more financially sound decision. Homeowners in Mimico and New Toronto with older furnaces often find that the cost of a major repair, combined with rising energy bills from an inefficient system, makes replacement the smarter move.
Honest Advice, No Pressure
A cracked heat exchanger is a safety issue — it can allow carbon monoxide to enter your living space. If we find one, we'll tell you clearly and explain your options honestly. We won't leave you in a dangerous situation or pressure you into a decision you're not ready for. We'll give you the numbers so you can decide for yourself.

Furnace Repair in Etobicoke
How quickly can you respond to a furnace breakdown?
For standard service calls we typically schedule within 24 hours. For emergencies where you're without heat, we prioritize same-day or next-morning response — including evenings and weekends. A furnace failure in an Etobicoke winter is not something you wait out.
My furnace turns on but shuts off after a few seconds. What's wrong?
This is most commonly a dirty or failing flame sensor. The sensor detects whether the burner has lit successfully and shuts the gas off if it doesn't get a signal. It's one of the most common furnace repairs we do and usually a quick fix.
Is a yellow flame on my furnace dangerous?
It can be. A yellow or orange flame often indicates incomplete combustion and the potential presence of carbon monoxide. Turn the furnace off and call us — this one shouldn't wait.
Do you repair all furnace brands?
Yes. We service all major brands including Lennox, Carrier, Goodman, Keeprite, Trane, York, and others. We carry common parts for the most frequently serviced brands on our trucks.
Do you repair furnaces in Long Branch and Mimico?
Yes. We serve all of Etobicoke including Long Branch, Mimico, New Toronto, Alderwood, Sunnylea, Royal York, Richview, and surrounding neighbourhoods.
My furnace is making a banging sound when it starts up. Should I be worried?
A banging sound on startup usually means delayed ignition — gas is building up slightly before it ignites. It's worth having looked at promptly as it puts stress on the heat exchanger over time.
How much does a furnace repair cost?
It varies by the issue. Simple repairs like flame sensor cleaning or igniter replacement are among the more affordable service calls. Control board or gas valve replacements are more involved. We give you a firm price after diagnosis, before any work begins.
What if my heat exchanger is cracked?
A cracked heat exchanger is a safety concern because it can allow combustion gases including carbon monoxide to mix with the air circulating through your home. We'll explain exactly what we found and what the repair or replacement options are — clearly and without pressure.
