Common Furnace Problems in Richmond Hill Homes
The area is a mix of established neighbourhoods around Yonge and newer subdivisions toward Oak Ridges and Jefferson. Different homes bring different furnace faults.
Blocked Condensate Traps
High efficiency condensing furnaces can stop working when condensate traps become blocked.
Pressure Switch Errors
Pressure switch faults can interrupt the heating cycle and require professional diagnosis.
Iced Intake Terminations
Intake terminations can ice over after freezing rain, affecting the operation of condensing furnaces.
Control Board Failures
Control boards reaching the end of their service life can cause furnace faults.
Ignition and Blower Problems
Older furnaces often experience dirty flame sensors, failed igniters, blower motors and capacitor problems.
Cracked Heat Exchangers
Some older furnaces develop cracked heat exchangers, which require immediate professional attention because of safety risks.
How the Visit Works
Our technicians diagnose the problem, explain the findings and provide clear pricing before any furnace components are replaced.
Diagnose the Fault
The technician inspects the furnace and identifies the cause of the heating problem.
Explain the Repair
You receive an explanation of the fault and the repair price before any work begins.
Complete the Work
Nothing is replaced before you agree. The diagnostic costs nothing when it leads to a repair with us.
What an Annual Service Covers
A maintenance visit is not a quick look. Our technicians inspect and test the important components that keep your furnace operating safely and reliably.
Burners are cleaned and inspected as part of the maintenance visit.
The flame sensor is serviced to help maintain reliable furnace ignition.
The heat exchanger is inspected for signs of deterioration and potential safety concerns.
Gas pressure and temperature rise are measured against manufacturer specifications.
Airflow and the furnace filter are assessed for restrictions affecting heating performance.
Every safety control is tested as part of the furnace inspection.
The thermostat is checked for calibration and correct operation.
The condensate system is cleared on high efficiency furnaces.
When to Call Rather Than Wait
Your furnace often gives warning signs before a complete breakdown. Having these symptoms inspected early can help prevent more expensive repairs.
Frequent Short Cycling
A furnace cycling on and off every few minutes can indicate an underlying heating problem.
Unusual Furnace Noises
A new or unfamiliar noise can signal a component beginning to fail.
Cooler Air Than Normal
Air that feels cooler than it used to may indicate reduced heating performance.
Repeated Breaker Trips
A furnace repeatedly tripping a breaker needs professional inspection. Stop resetting the breaker.
Unexpected Gas Bill Increase
A sudden jump in your gas bill without a change in weather can indicate a heating efficiency problem.
Repeated Furnace Shutdowns
If the furnace keeps shutting itself down, stop resetting it and contact a qualified technician.
