Furnace Repair in Windsor, ON
Windsor winters are milder than most of Canada, but a furnace that fails during a January cold snap still leaves the house cold fast. A few checks may get it running while you wait.
Request an HVAC technicianThermostat and power
Make sure the thermostat is on heat and set a few degrees above the room temperature, with fresh batteries. Check the breaker and the furnace service switch, which often looks like an ordinary light switch near the furnace or at the basement stairs.
Filter
A clogged filter restricts airflow, overheats the furnace and can make it shut itself off. Slide it out and look; if it's grey and dusty, replace it and give the furnace a few minutes to restart.
Blinking lights
Most modern furnaces show a blinking status light through a small window. Count the pattern and compare it with the chart on the panel door. Write the code down for the technician, since it often points straight to the fault.
Cold air from the vents
If the fan runs but the air stays cool, the burners may not be lighting or may be shutting off. A dirty flame sensor, a failing igniter or a venting problem are the usual causes.
Vent pipes outside
High-efficiency furnaces vent through two plastic pipes on an outside wall. Snow drifts, ice or a bird's nest can block them, and the furnace stops to protect itself. Clear them gently by hand.
Short cycling
A furnace that starts and stops every few minutes wears out parts quickly. A dirty filter, an oversized furnace or a faulty sensor can be behind it, and it's worth a visit.
Carbon monoxide
Every home with a gas furnace needs working carbon monoxide alarms near the bedrooms. If one sounds, get everyone outside and dial 911.
Gas smell
If you smell gas, leave the house and contact the gas utility from outside. Don't switch lights or appliances on or off on the way out.
