Check the business you are actually hiring
A website, branded van and convincing salesperson do not establish which business is responsible for your job. Ask for the legal business name, address, contact details and the name that will appear on the contract and invoice. If the salesperson represents another installer, ask how that relationship works and who is accountable for the finished result.
In Toronto, a heating project can involve several trades and subcontractors. The homeowner should not have to discover their roles after work starts. Ask who coordinates the job and who handles defects, warranty visits and complaints. Keep the proposal linked to the verified business rather than assuming every company using a similar trade name is the same operation.
Match qualifications to the work
TSSA's contractor directory identifies registered businesses authorized for fuels-related work in Ontario. Verify the relevant business independently and check that the planned work fits its role. A contractor's registration and an individual technician's qualifications are related checks, not interchangeable substitutes for one another.
Where electrical contracting is involved, ESA advises hiring a Licensed Electrical Contractor and verifying the licence through its official tools. Ask who will perform that work if the heating company uses a subcontractor. These checks do not guarantee a perfect project, but they establish essential accountability. A general claim that everyone is licensed is weaker than identifying the responsible parties for the actual work in your home.
Evaluate the assessment, not just the pitch
A credible proposal should follow an assessment of the house and current system. Listen for questions about occupied rooms, existing comfort, distribution, electrical constraints and planned renovations. The contractor should explain why the recommended design suits those conditions.
Be cautious when equipment is selected only from the old label or the home's approximate floor area. Ask what remains to be inspected and whether the price could change afterwards. A careful contractor may identify uncertainties rather than promise a seamless job immediately. The quality of that explanation helps you distinguish a considered installation plan from a sales offer that leaves difficult decisions until the equipment is already at the property.
Request evidence for major claims
If the contractor says replacement is necessary, ask for the diagnosis and the basis for that conclusion. If the offer promises substantial savings, request the assumptions and calculation method. If the work is said to qualify for assistance, verify the program directly and match the exact equipment and property conditions.
Do not interpret questions as a challenge to every recommendation. They help both parties identify the decision being made. A sound answer may include a repair option, further testing or a limitation on what can be concluded during the first visit. A claim that requires immediate commitment before the supporting information can be provided deserves particular scrutiny when no emergency has been established.
Use references to ask specific questions
A reference is most helpful when the previous project resembles yours: an occupied Toronto semi, a finished basement, a heat-pump conversion or a hydronic upgrade. Ask whether the quoted scope was delivered, how changes were handled and whether follow-up occurred. Generic praise offers less information about the kind of work you need.
Online reviews can reveal patterns but should not replace registration, design and contract checks. Consider whether complaints concern communication, unresolved performance or unexpected charges. Ask the contractor directly about their process for those issues. Do not assume a large number of favourable reviews proves the proposed equipment is correctly sized or that a particular technician will attend your installation.
Agree the responsibilities in writing
The contract should identify equipment, work, exclusions, payment stages and expected completion arrangements. Ask who obtains any required permissions and how you will receive the relevant records. Ontario's homeowner contract guidance provides a useful reference for reviewing substantial renovation and repair commitments.
Ask about insurance and how property damage would be handled. Confirm the process for changes and the approval needed before extra charges are incurred. If a subcontractor performs part of the installation, the agreement should make the coordination clear. Documents should allow you to compare the final work with what was promised without depending on an oral description from a salesperson who is no longer involved.
Know the follow-up route before paying
Request the contact route for installation concerns, routine service and warranty matters. Ask whether the company will explain commissioning records and demonstrate controls at handover. A vague promise that someone will call later leaves avoidable uncertainty after a major purchase.
Before final acceptance, reconcile equipment and work against the agreement and identify unresolved items. Keep all versions, invoices and relevant correspondence. If a problem arises, provide a concise record of the symptom, dates and previous responses, then use the documented complaint route. Verification before hiring cannot remove every risk, but it makes responsibility much clearer than choosing on a phone number, a low price or urgency alone.
