No heat in a Vaughan winter or no AC during a heatwave can become dangerous fast. Big League's HVAC emergency team is available 24/7 — no overtime charges, upfront pricing before any work begins.
An HVAC emergency is any situation where your heating or cooling system has failed during conditions that create a health or safety risk. In Vaughan, that means: no heat during temperatures at or below -10°C — especially in homes with infants, elderly residents, or medical conditions — and no cooling during heat warnings when indoor temperatures climb above 35°C. It also includes any suspected gas leak associated with the furnace or HVAC system, carbon monoxide alarm activation, or active flooding from a failed AC condensate line. If your situation doesn't qualify as a medical emergency but you're without heat or cooling and need service fast — we still treat it as a priority call.
When you call 647-558-8458 for an HVAC emergency, you reach a live dispatcher at any hour. We assess the situation over the phone to determine if there's an immediate safety risk, confirm your address, and dispatch the closest available tech with a priority assignment. Your tech arrives with the most common replacement components for both furnace and AC systems — igniters, capacitors, contactors, and sensors — and the tools to diagnose the failure quickly. If the repair can't be completed same-visit due to parts availability, we advise you on interim safety measures and confirm a follow-up slot within 24 hours.
Emergency HVAC service in Vaughan ranges from $185 to $850+ depending on the failure type and parts required. Big League does not charge overtime premiums — your rate is the same at midnight in January as it is at noon in July. All pricing is flat-rate and confirmed before work begins. A $99 diagnostic fee applies when the cause is unknown; this is waived if you proceed with the repair.
