Emergency HVAC in Ottawa, ON

A deeper look at how Ottawa conditions shape the emergency hvac work owners actually need.

Ottawa's no heat emergency call pattern is predictable in its timing. The highest call volume arrives between midnight and 6am on the first extremely cold night of a new cold snap, after the furnace has been cycling at high frequency for several hours and a failing component finally gives out. The three most common failure modes in Ottawa no heat calls are: first, a cracked heat exchanger in a furnace over 20 years old, which causes the safety limit switch to trip and shut down the furnace; second, an inducer motor failure in a condensing furnace, which prevents exhaust venting and triggers the pressure switch lockout; and third, an iced condensate vent in a condensing furnace, where the exhaust pipe termination freezes during sustained minus 20 Celsius temperatures and blocks the venting system, causing a safety lockout. Each of these has a distinct fix. A cracked heat exchanger requires furnace replacement, and in an emergency context we provide a temporary space heating solution while the replacement is scheduled, typically next business day. We maintain a stock of common furnace models to reduce lead time on emergency replacements. An inducer motor failure is often repairable on the same visit if we carry the motor for that furnace model.

A frozen condensate vent can be cleared in 20 to 30 minutes, with a modification to the vent termination to prevent recurrence. Our emergency TSSA technicians carry a diagnostic kit that covers all three of these scenarios and can confirm the failure mode within 30 minutes of arrival. We also carry CO detectors and test for CO presence in the supply air before and after any furnace repair, because CO exposure from a cracked heat exchanger is a risk during the failure period and must be confirmed clear before the furnace is returned to service. In an emergency furnace replacement scenario in Ottawa, we assess whether the property can be adequately heated with space heaters overnight while the replacement furnace is sourced and installed. We document the space heater deployment and maintain communication with the property owner throughout. Displacement to a hotel is a last resort, and we work hard to provide a solution that keeps tenants in the building safely. Call 1-855-910-9090.
