Gas appliance work in BC must comply with standards overseen by Technical Safety BC.
Why Furnaces Fail in Burnaby
Many Burnaby repair calls come from systems with airflow restrictions or aging parts that were never properly maintained.
Dirty Filters and Restricted Airflow
Restricted airflow overheats the furnace and causes limit switch trips. This is one of the most common reasons for short-cycling.
Old Ignition Components
Igniters and flame sensors wear down over time and prevent proper burner ignition.
High-Efficiency Condensate Problems
Modern furnaces produce condensate water. Blocked drains or venting issues can shut the system down.
Blower Motor Problems
Weak airflow, loud noise, or overheating can point to blower issues.

Repair or Replace Your Furnace?
Some furnaces are worth repairing. Others are just collecting invoices at this point.
Repair usually makes sense when:
- Furnace is under 12–15 years old
- Problem is isolated to one component
- Comfort was good before the failure
- No major airflow or safety problems exist
Replacement often makes more sense when:
- Furnace is 15–20+ years old
- Repairs happen repeatedly
- Heat exchanger or major motor issues appear
- Comfort remains uneven year after year
If replacement is becoming the smarter option, review gas furnace installation in Burnaby.

FAQ – Furnace Repair Burnaby
Why does my furnace keep turning off?
Short-cycling is commonly caused by dirty filters, airflow restriction, overheating limit trips, or flame sensor problems.
Why is my furnace blowing cold air?
Cold air often points to ignition failure, burner issues, pressure switch faults, or overheating shutdowns.
Do you repair high-efficiency furnaces in Burnaby?
Yes. High-efficiency gas furnaces often require checks on condensate drains, venting, pressure switches, and ignition systems.
Should I repair or replace my furnace?
If the furnace is newer and the issue is isolated, repair usually makes sense. Older systems with repeated failures often become better replacement candidates.
