Verification guide

TSSA furnace contractor checklist

For fuel-related furnace work in Ontario, verify the business through the Technical Standards and Safety Authority before engagement.

What TSSA says

TSSA states that registered fuels contractors are the only businesses legally authorized to perform fuels-related work in Ontario. The registry is a verification tool, not an endorsement.

What to record

Provider name, current registration/authorization number, fuel type authorization, service area, and whether the registration is active at the time of engagement.

Official registry

Use the official TSSA Authorized Heating Fuel Contractors registry to verify the contractor directly.

Prepare a stronger tssa furnace contractor checklist request

A useful request gives an independent provider enough context to decide whether tssa furnace contractor checklist fits its coverage, capability and current capacity without pretending an online form can determine the final scope.

Information worth preparing

What can change provider fit

Provider fit can change materially based on fuel or equipment capability and service area, repair, maintenance or replacement scope, and current contractor capacity.

Where the matching layer stops

This is a non-emergency matching service, not a diagnosis. For an immediate fire, gas or carbon-monoxide concern, use the appropriate emergency or utility response.

What a provider-ready brief should make clear

A provider-ready furnace request should describe the observable issue, fuel type if known, approximate equipment age, location and desired timing. Note whether there is no heat, intermittent operation, airflow concern, maintenance need or replacement interest. Do not use the form to self-diagnose an immediate gas, fire or carbon-monoxide concern.

How to compare the next step

Compare contractors on relevant equipment capability, response timing, diagnostic or dispatch charges, what is included in the proposed repair or replacement scope and how warranty or follow-up is handled. Licensing and code requirements should be verified for the actual work being performed.
