No Heat in Etobicoke, and What Usually Causes It
When a furnace stops producing heat, the cause is almost always one of five common problems.
Thermostat Problems
The thermostat may be set wrong or its batteries may be flat, preventing the furnace from responding to heating requests.
Blocked Furnace Filters
A blocked filter can restrict airflow and cause the furnace to overheat and enter a safety lockout.
Failed Furnace Igniter
A failed igniter can prevent the furnace burners from lighting and producing heat.
Dirty Flame Sensor
A dirty flame sensor can cause the burner to light and then cut out after a few seconds.
Tripped Safety Limits
A safety limit may have tripped, preventing the furnace from running until the underlying fault is cleared.
Repeated Furnace Lockouts
If the furnace keeps shutting down after a reset, stop resetting it. The lockout is protecting you from an underlying problem.
A Mixed Housing Stock Means Mixed Equipment
Etobicoke runs from postwar bungalows through to lakeshore condominium towers and recent townhouse developments, and the heating equipment is just as varied.
We work on conventional atmospheric furnaces venting into a masonry chimney, often found in older homes.
Our technicians service sealed combustion high efficiency units with side wall venting.
We also service compact furnaces installed in townhouse mechanical closets where access is limited.
Price Before the Work
The number is agreed before anything starts.
The diagnostic service call is free when it leads to a repair with us, the repair price is quoted up front, and there is no charge that appears later.
Our goal is to make the repair process clear before work begins.
Repair and Installation Warranties
Repairs are covered for two years.
New installations carry a 10 year warranty on manufacturer parts and two years on labour.
The full warranty terms are set out on our website.
Repair or Replace Your Furnace?
Age and the size of the repair usually settle whether furnace repair or replacement makes better financial sense.
When Repair Makes Sense
Under ten years old with one failed component, repair is almost always the right call.
Fixing the failed part can restore normal heating without replacing the entire system.
When Replacement Makes Sense
Past fifteen years, when the repair is worth a large share of a new system and the efficiency is poor enough to show in the gas bill, replacement usually makes better sense.
Gas Safety
If you smell gas, leave the building before you do anything else.
Do not touch light switches, appliances or your phone inside, and do not start a vehicle in an attached garage.
From outside, call 911 or the Enbridge Gas emergency line, then call us.
