Before you compare quotes
The calculator starts with a diagnostic visit, not a completed repair. Select furnace repair or AC repair to see the corresponding published range. Ask whether the diagnostic charge is credited toward the repair, and whether parts and labour are included.
The AC repair figures use an older Toronto source. These are planning ranges, not current offers from providers; check the source dates below and request a written quote for your equipment and fault.
Tell the contractor the equipment type, make and model, symptoms and any displayed error code. Ask for separate diagnostic, repair and replacement options before approving work.
Prices exclude HST. Confirm the total, scope and any additional charges before booking.
