How often should a furnace be inspected?

TSSA advises Ontario residents to have fuel-burning appliances inspected annually through a TSSA-registered fuels contractor. Manufacturer requirements and the equipment’s condition may also affect the maintenance schedule.

Does furnace maintenance prevent every breakdown?

No. Maintenance can identify operating issues, wear, contamination, venting concerns, and airflow problems, but components can still fail later. It provides a better condition check, not a breakdown guarantee.

What should I do if my CO alarm sounds?

Leave the home immediately, move to fresh air, and call 911 or the fire department from outside. Do not search for the source or re-enter until emergency personnel say it is safe.

Heating Tune-Ups

Furnace maintenance that checks operation, safety, and airflow together.

A furnace tune-up should be more than a filter swap. We review the equipment, thermostat call, ignition sequence, burner operation, venting, condensate where applicable, blower, accessible electrical components, airflow symptoms, and the condition that may affect the coming heating season.

What This HVAC Service Includes

Operating and safety checks

Burner and ignition review

Filter and airflow assessment

Venting and condensate inspection

Maintenance establishes a useful baseline

We ask about noise, odours, short cycling, cold rooms, filter history, error codes, and recent repairs before running the system. That context helps distinguish a routine cleaning item from a recurring fault. Findings are explained in plain language, including what needs attention now, what can be monitored, and what may affect future replacement planning.

Combustion equipment requires qualified service

Fuel-fired equipment, gas piping, ignition, burners, venting, and safety controls should be assessed by qualified personnel working for a TSSA-registered fuels contractor where Ontario rules require it. If a gas odour or carbon-monoxide alarm is present, occupants should leave and contact the gas utility or emergency services rather than waiting for a routine appointment.

Airflow problems often show up at the furnace

A restrictive filter, blocked return, closed registers, dirty blower components, altered ductwork, or an equipment setting can affect comfort and operation. Maintenance is a chance to connect homeowner complaints with what the system is doing. It is not a guarantee against every future breakdown, but it can identify visible wear and operating concerns before peak demand.

Diagnose

We confirm symptoms, system type, thermostat behavior, airflow, equipment condition, and urgency before recommending next steps.

Plan

Repair, replacement, controls, ductwork, ventilation, and comfort issues are scoped clearly before work starts.

Service

Heating and cooling work is completed with safety, access, setup, and system operation in mind.

Confirm

We review operation, explain findings, and outline maintenance or replacement considerations when relevant.

A Burning Smell From the Furnace: What to Do First

A brief dusty smell at seasonal startup is different from melting plastic, smoke, a gas odour, or a carbon-monoxide alarm. Treat the warning sign before trying to name the failed part.
