Call (343) 227-3610 NowWhat Counts as an HVAC Emergency?
If any of these describe your situation right now, skip the form and pick up the phone. We triage calls by severity — life-safety situations (gas leaks, CO alarms) are dispatched immediately.
Why Ottawa Homeowners Call DTech for Emergency HVAC Repairs
Ottawa-Based Dispatch
Our trucks roll from within the city — no waiting for a crew to drive in from Toronto or Kingston. Average arrival time inside the Greenbelt is well under two hours for after-hours calls.
TSSA Gas & 313D Refrigeration
Every technician on our emergency roster holds active TSSA G2/G3 gas-fitter and 313D refrigeration-mechanic licences. We don't subcontract emergency work to unlicensed helpers.
ESA-Compliant Electrical
Heat-pump and furnace electrical connections are inspected and wired to Ontario Electrical Safety Authority standards — critical when dealing with circuit overloads or wiring faults.
Parts On the Truck
Our vans carry hot-surface igniters, flame sensors, control boards, capacitors, contactors, and common blower motors. About 70% of no-heat calls are resolved without a second trip.
Cold-Climate Triage
We've seen what −30 °C does to under-insulated supply lines, outdoor heat-pump coils, and condensate drains. Our techs diagnose freeze-related failures faster because they deal with them every winter.
Members First
Maintenance-plan members are prioritised in the dispatch queue — Total Care members get a 24-business-hour response window even during peak January demand.
What Happens When Our Tech Arrives
Gas leak detection with a combustible-gas analyser, CO readings in the mechanical room, and a visual check for water or electrical hazards.
Read error codes, test voltage at the control board, check flame-sensor microamp readings, verify thermostat signal — a structured process, not guesswork.
If the part is on the truck, we fix it on the spot. If a special-order part is needed, we set up a temporary workaround (portable heater, bypass) to keep you safe until the part arrives.
You see the cost before we proceed. Emergency diagnostic fees are clearly stated — and waived for qualifying maintenance-plan members.
We run a full heating or cooling cycle, measure supply-air temperature, and confirm the system holds steady before leaving your home.
You receive a digital report of what failed, what was repaired, and any recommendations for follow-up — emailed before we pull out of your driveway.
Priority Service for Maintenance Plan Members
Our three membership tiers (Essential, Comfort, Total Care) include escalating emergency priority — from 72-business-hour scheduling down to 24-business-hour response. Members also receive waived or reduced diagnostic fees, so the plan often pays for itself with a single after-hours call.
