Common Furnace Problems We Fix in Surrey
Surrey homes see a wide range of furnace issues, from age-related wear to poor maintenance to installation problems that show up years later. Here are the most common repairs we handle:
Ignition or Pilot Light Problems
Modern furnaces use electronic ignition systems that can fail due to heat, wear, or electrical issues. Older furnaces still use pilot lights that can go out or burn yellow. When ignition fails, you get no heat or weak heat even though the furnace is running.
Dirty or Failing Flame Sensor
A dirty flame sensor can cause the furnace to start, then shut down after a few seconds. Cleaning or replacing the sensor is usually quick and affordable, but it's a common cause of "furnace won't stay on" calls.
Blower Motor or Capacitor Issues
The blower motor pushes warm air through your ducts. If the motor or its capacitor fails, you might get heat but no airflow, or the furnace might hum without starting. Capacitor replacement is one of the most common furnace repairs we do.
Thermostat Malfunctions
Sometimes the furnace is fine and the thermostat is the problem. Dead batteries, faulty wiring, or an outdated thermostat can make your furnace behave erratically or not respond at all.
Heat Exchanger Cracks
A cracked heat exchanger is serious. It can leak carbon monoxide into your home and usually means the furnace needs to be shut down until it's replaced. This is more common in older furnaces and is one of the main reasons we recommend replacement over repair on older units.
Draft or Venting Issues
If the furnace can't vent exhaust properly - due to a blocked vent, draft problem, or failing inducer motor - it will shut down for safety. This is common after recent renovations, new windows, or when vents are blocked by snow, debris, or plants.
Filter and Airflow Problems
A clogged air filter is the most common preventable furnace issue. It restricts airflow, causes overheating, and can lead to more expensive repairs if ignored. Regular filter changes are the easiest way to avoid most breakdowns.

Signs Your Furnace Needs Repair
Now that you know what kinds of furnace problems we fix every day, here's how to tell when it's time to call for help. If your furnace is doing any of the things below, it's not worth waiting around hoping it will "sort itself out." Book furnace repair for your Surrey home before it quits completely.
- No heat or weak heat when the thermostat is set to "Heat" and the system has been running for a while.
- Frequent cycling - the furnace turns on and off more often than normal, which can signal a thermostat issue, overheating, or a failing component.
- Strange noises like grinding, rattling, loud buzzing, or a deep rumbling from the furnace cabinet.
- Yellow pilot light or burner flame instead of a steady blue flame, which can indicate a combustion problem.
- Burning, musty, or electrical odours from the vents, especially on the first few runs of the season. Burning smells on startup for the first time can be normal, but strong or persistent odours are not.
- Rising energy bills without a change in usage, which can mean your furnace is working harder than it should.
- Thermostat issues - the furnace doesn't respond to the thermostat, or the temperature in your home doesn't match the setting.
- Breakers tripping or the furnace shutting down mid-cycle repeatedly.
If you smell gas or suspect a carbon monoxide leak (headaches, dizziness, nausea), shut the system off immediately, leave the house, and call for help.
Repair vs. replace: when does an AC upgrade make sense?
We know no one wakes up excited to replace their furnace. When you're staring at a repair quote, it helps to have a simple way to think about whether it's better to fix what you have or start planning for a replacement. We won't push you toward a replacement just to make a sale - if your furnace can be repaired and still serve you well, we'll tell you that upfront. When we talk this through with homeowners, we usually look at three things in a bit more detail.
Age of the system
Many furnaces last around 15-20 years when properly maintained. Up to about 10 years old, a repair on a well-maintained furnace is usually straightforward unless there's a major component failure. Once you hit 15+ years, even with good maintenance, parts start wearing out more often, efficiency drops, and newer models are significantly more efficient. At that point, spending a few hundred dollars on a repair that might not last another season is harder to justify compared to putting that money toward a new furnace that will last another 15-20 years.
Cost of the repair
HVAC pros often use a simple "$5,000 rule" to keep decisions grounded. Multiply the repair cost by the age of the furnace in years, and if the total is over 5,000, replacement is usually the smarter move. For a furnace that's 16 years old needing a $400 repair, that's 6,400 - well over the threshold. At that point, you're better off comparing that cost to a new, more efficient furnace that won't need another repair in six months.
How Your Home Feels When the Heat Is On
We also pay attention to how your home has heated up over the years, not just whether the furnace turns on. If certain rooms never get warm, the system cycles on and off constantly, or you're fighting with the thermostat to keep things comfortable, those aren't just quirks. They're signs the furnace might be the wrong size, your ductwork might need attention, or the system is near the end of its reliable life. A new, properly sized furnace can make a real difference in how evenly your home heats and how much you spend on energy each winter.

FAQ: Furnace Repair in Surrey
How do I know if my furnace needs repair or just maintenance?
If your furnace is making strange noises, not heating properly, cycling frequently, or has a yellow flame, it likely needs repair. If it’s just dusty, smells a bit on first startup, or hasn’t been serviced in a while, maintenance might be enough. When in doubt, book a diagnostic visit and we’ll tell you which you need.
How much does furnace repair cost in Surrey?
It depends on the problem. Simple repairs like a thermostat battery change, capacitor replacement, or flame sensor cleaning can be a few hundred dollars. More complex repairs like a blower motor, control board, or heat exchanger can run higher. We give you a clear quote before starting any work.
How long does a typical furnace repair take?
Most common repairs are done in 1-2 hours on site. More complex issues like heat exchanger problems or venting issues can take longer. We’ll give you a time estimate when we diagnose the problem.
Should I repair my old furnace or replace it?
If your furnace is under 10 years old and has been maintained, repair is usually the better choice. If it’s 15+ years old, needs frequent repairs, or the repair cost is high relative to its age, replacement may be more cost-effective. We’ll walk you through both options.
Do you offer emergency furnace repair in Surrey?
Yes, we offer emergency and after-hours furnace repair when available. Call us and we’ll let you know the earliest available slot and any after-hours fees upfront.
Is a clicking furnace normal?
A few clicks when the furnace starts are normal. Repeated clicking, clicking without the furnace starting, or clicking during operation is not normal and usually indicates an ignition or electrical issue.
What should I do if my furnace stops working?
Check the thermostat (is it set to Heat, are the batteries dead?), check the furnace switch (is it on?), check the breaker (did it trip?), and check the air filter (is it clogged?). If none of these fix it, call us for a diagnostic visit.
What is the most common problem with a furnace?
The most common furnace problem is ignition or pilot light failure. If the furnace can’t ignite, you get no heat even though the system is trying to run. Dirty flame sensors, failed igniters, and pilot light issues are all common causes.
What is the most common part to fail on a furnace?
The capacitor is the most common part to fail on a furnace. It gives the blower motor the boost it needs to start, and it wears out from heat and electrical stress over time. Capacitor replacement is one of the most common and affordable furnace repairs.
What is the most expensive part to fix on a furnace?
The heat exchanger is the most expensive part to fix on a furnace. If it cracks, it usually needs to be replaced, which can cost as much as a new furnace. A cracked heat exchanger is also a safety concern because it can leak carbon monoxide.
What are the most common furnace repairs?
● Capacitor replacement
● Flame sensor cleaning or replacement
● Igniter replacement
● Blower motor repair or replacement
● Thermostat replacement
● Draft inducer motor repair
● Control board replacement
● Filter and airflow issues
How many years does a furnace usually last?
A well-maintained furnace typically lasts 15-20 years. Up to about 10 years old, repairs are usually straightforward. Once you hit 15+ years, parts wear out more often, efficiency drops, and replacement often makes more sense than repeated repairs.
Is it worth it to get a furnace tune-up?
Yes, a furnace tune-up is worth it. Regular maintenance catches small problems before they become expensive repairs, keeps your furnace efficient, ensures safe operation, and extends the life of your system. Most manufacturers also require annual maintenance to keep your warranty valid.
