When a furnace starts acting up, it's more than an inconvenience it's a sign that something behind the scenes needs attention. Recently, the team at Vive Brant responded to a furnace repair in Brantford after a homeowner noticed their system was producing intermittent heat. The furnace would start heating, shut down unexpectedly, and then try to restart a pattern that's both frustrating and common in the colder months.
The Issue: Stop-and-Start Heating
At first, the furnace seemed to work normally:
Thermostat called for heat, burners ignited, and warm air flowed.
Then, the system shut off mid-cycle and tried restarting.
No error codes were showing but the problem was clear.
This type of behavior often signals a hidden safety or airflow issue, which is exactly what our team set out to diagnose.
What Our Technicians Found
Once on site, the Vive Brant team inspected the furnace and observed the heating sequence in real time. The burners were igniting properly, but the system was shutting down mid-cycle.
After running diagnostic tests, it was discovered that one of the furnace pressure switches was opening intermittently, causing the gas valve to lose power and shut the system down as a safety measure.
Further inspection revealed loose exhaust vent connections, which were affecting proper airflow and pressure inside the system. This brief loss of pressure was enough to trigger the shutdowns.
The Solution: Correcting Airflow and Ensuring Safe Operation
The team secured the exhaust vent connections and verified that the inducer motor was operating at the proper pressure. In addition, the technicians:
- Checked and cleared all condensate drains
- Cleaned the flame sensor
- Monitored the furnace through multiple full heating cycles
After extended testing, the furnace continued to operate normally, providing consistent heat without interruption.
Why Intermittent Furnace Heat Shouldn't Be Ignored
Many homeowners assume inconsistent heat is a minor issue or thermostat-related, but in reality, it's often a warning sign. Left unresolved, problems like this can lead to:
- Unexpected furnace breakdowns
- Increased energy costs
- Reduced furnace lifespan
- No heat when you need it most
