Condensing furnaces drain acidic condensate, and a clogged trap or line is the most common reason they leak. When a furnace leaks water it is almost never gas — it is condensate or cooling-related water. High-efficiency (condensing) furnaces drain acidic condensate, and in summer the water you see is often from the air-conditioning coil sitting in the same cabinet. Our Red Seal technicians have kept Metro Vancouver homes warm and dry since 1999 — call (604) 359-1081 for same-day help.
Most furnace leaks trace back to one of these causes:
Standing water near the furnace control board, blower, or gas valve can short electronics and create a shock hazard. Shut the furnace off and keep water away from electrical. If you ever smell gas, treat it as a gas emergency — leave and call from outside.
A CANRO technician clears and tests the condensate trap, line and pump, checks the AC pan and drain, inspects the humidifier, and verifies the secondary heat exchanger and inducer. We fix the actual source and test a full heat cycle before we leave.
Most furnace condensate and drainage leaks are repaired for about $150–$450. A new condensate pump runs roughly $250–$500 installed. A cracked heat exchanger is a bigger conversation we will walk you through honestly. Every job starts with a clear, upfront price — no surprises.

Most summer furnace leaks are actually air-conditioning condensate from the coil and pan above the furnace, not the furnace itself. The fix is usually clearing the AC condensate drain.
The water itself can damage electronics and create a shock risk, so shut the unit down. A water leak is not a gas leak, but if you also smell gas, leave and call us right away.
