What We Repair
We repair gas furnace faults across the brands we carry and most brands we do not. From older conventional systems to modern high efficiency units, our technicians diagnose a wide range of heating problems.
No Heat Problems
Furnaces that stop producing heat require a proper diagnosis to identify the failed component or operating issue.
Intermittent Heating
A furnace that heats inconsistently may have ignition, control or airflow problems.
Ignition and Flame Problems
Furnaces that light and then cut out can have flame sensing or other ignition-related faults.
Constantly Running Blowers
A blower that runs continuously can indicate an issue with furnace controls or operation.
Strange Startup Noises
Unusual sounds during furnace startup can indicate mechanical components beginning to fail.
Repeated Safety Lockouts
A furnace repeatedly entering safety lockout needs professional diagnosis of the underlying fault.
Reduced Heating Output
Gradual loss of heating performance often comes from restricted airflow rather than the burner.
Conventional Furnaces
Older homes near Main Street South may have conventional chimney vented furnaces requiring specialized diagnosis.
High Efficiency Furnaces
Newer subdivisions east and west of Yonge often have sealed combustion furnaces with modern heating controls.
The Free Diagnostic, Explained Properly
The service call is free when the diagnostic leads to a repair with us.
That is the whole condition, and it is worth saying plainly because the industry is not always clear about it.
If we diagnose the fault and you have us carry out the repair, you are not charged separately for the visit.
Know the Price Before Work Begins
You are told the repair price before any work starts, so the invoice matches the number you agreed to.
Our technicians explain the diagnosed problem and the proposed repair before proceeding.
Book a Furnace Diagnostic →The Brands We Install and Service
We repair every make that comes through the door, including equipment we did not supply. For replacements, we carry thirteen furnace brands.
Repair, Replace, or Maintain
Choosing the right option depends on furnace age, repair cost and the condition of your heating equipment.
Repair Your Furnace
A furnace under ten years old with a single failed part is almost always worth repairing.
Repairing the failed component can restore heating without the expense of replacing the entire furnace.
Replace Your Furnace
Past fifteen years, with a repair worth a large share of a new system, replacement usually wins.
A cracked heat exchanger ends the discussion at any age because of the carbon monoxide risk.
Maintain Your Furnace
An annual tune up in early autumn catches faults that give warning.
It also keeps the service records your manufacturer warranty is likely to ask for.
