PREVENTATIVE HVAC & GAS APPLIANCE MAINTENANCE • TORONTO & THE GTA
Maintain your HVAC system before it becomes a repair call.
Professional preventative maintenance helps identify developing problems, keep equipment operating properly
and reduce the risk of unexpected breakdowns when you need your system most. DAVESDUCTS maintains furnaces,
air conditioners, heat pumps, air handlers, tankless water heaters, boilers, ductless systems and gas fireplaces.
WHY PREVENTATIVE MAINTENANCE?
Small problems are easier to deal with before they become big ones.
HVAC and gas-fired equipment accumulates dirt, wear and operating issues over time. Regular maintenance
gives a technician an opportunity to inspect, test and service the equipment before those conditions
contribute to poor performance or an unexpected service call.
Reduce Unexpected Breakdowns
Identify dirty components, deteriorating parts and abnormal operation before they result in a service call.
Maintain System Performance
Dirty coils, restricted filters and neglected components can reduce airflow, capacity and overall system performance.
Support Maintenance Records
Documented maintenance creates a service history for the equipment and may be useful when warranty support is required.

MAINTENANCE VS. REPAIR DIAGNOSIS
If the equipment has failed, the visit becomes a service call.
Maintenance pricing is intended for equipment that is operating and being serviced preventively.
If the equipment is not operating properly, has an active fault, will not ignite or our technician must
diagnose an equipment failure, the visit will be treated as a service call and the applicable
diagnostic/service-call rate will apply. Repairs, replacement parts and additional labour are extra
unless specifically quoted or authorized.
WHAT YOU’RE PAYING FOR
A maintenance visit is more than a quick visual check.
Most HVAC maintenance visits take approximately 1.5–2 hours, depending on the equipment, condition,
access and findings. Service time for gas fireplaces and other appliances varies by design,
accessibility and condition.
Licensed HVAC Service
Maintenance is performed by qualified technicians who can identify when a condition requires diagnosis or repair.
System-Level Checks
We evaluate applicable controls, safety devices, airflow, electrical, drains, combustion and operating conditions.
Documented Findings
Where deficiencies are found, DAVESDUCTS can explain what was observed and what corrective work should be considered.

A boiler can be operating while pumps, expansion control, zoning, combustion or system pressure are
developing problems. DAVESDUCTS can maintain, service and repair hydronic systems as part of our broader mechanical scope.
Boiler Operation
Inspect boiler operation, controls, thermostat and zoning response.
Hydronic Components
Inspect pumps, expansion tank, accessible piping, system pressure and temperature.

GAS FIREPLACE MAINTENANCE
Gas fireplace maintenance & safety inspection.
Regular gas fireplace maintenance helps identify ignition, combustion, venting and component issues before
they contribute to unreliable operation. The exact scope varies by fireplace design, condition and accessibility.
Gas fireplace maintenance applies to an operating appliance receiving preventative service. If the fireplace
will not ignite, repeatedly shuts down, has an active fault or requires troubleshooting, the appointment
becomes a diagnostic service call. Repairs, replacement parts and additional labour are extra.
MAINTENANCE VS. REPAIR
Maintenance is not the same as troubleshooting a malfunction.
If equipment is already failing, showing an error code, not heating, not cooling, not igniting, leaking
or repeatedly shutting down, the correct appointment may be a diagnostic service call rather than routine maintenance.
Book Maintenance When
- The equipment is operating normally
- You want seasonal preventative service
- You want the equipment inspected and cleaned
- You are maintaining a service history
Book a Service Call When
- The equipment is not heating, cooling or igniting
- An error code or lockout is present
- There is water leakage or abnormal noise
- Performance has changed significantly
- You need fault diagnosis and repair
WHEN TO SCHEDULE
Book before peak season — not during the first extreme-weather breakdown.
Customers are responsible for arranging their maintenance visits. We recommend scheduling heating
maintenance before the heating season and air-conditioning maintenance before the cooling season.
Heating Equipment
Schedule furnaces, boilers, hydronic systems and heating-mode heat pumps before the heating season where practical.
Gas Fireplaces
Schedule fireplace maintenance before regular fall and winter use so ignition, burner operation, venting and combustion can be checked.
Cooling Equipment
Schedule central AC and cooling-mode heat pump maintenance before sustained hot weather arrives.
Tankless & Year-Round Systems
Tankless water heaters and systems used throughout the year can be scheduled based on usage, water quality and maintenance history.
