Where the Water Comes From
Bryant high-efficiency furnaces (90%+ AFUE condensing models such as the Preferred and Evolution series, which share their core design with Carrier) deliberately wring extra heat out of the exhaust gases. The trade-off is condensation: water vapour cools into liquid inside a secondary heat exchanger and must drain away. That condensate is mildly acidic and travels through a trap, drain hoses, and often a condensate pump.
A small amount of contained water is normal. A puddle on the floor is not. It means the condensate route is blocked or leaking, or the moisture is coming from the air-conditioning coil installed in the cabinet above the furnace. Sorting out which one is happening leads straight to the fix.
Common Bryant Furnace Leak Causes
Clogged condensate trap or drain. Bryant's internal trap and tubing collect sediment and biofilm, eventually backing up and overflowing. This is the most frequent cause we see.
Condensate pump problems. Where the drain sits above floor level, a pump moves the water out. A jammed float, burned-out motor, or unplugged pump leads to overflow.
Cracked or disconnected drain lines. The flexible hoses and trap fittings can split or pop loose, often after a service or a bump.
AC coil condensate. During cooling season the evaporator coil above the furnace produces its own water. A plugged coil pan or drain line drips onto the furnace, masquerading as a furnace leak.
Heat exchanger corrosion. Over many years, acidic condensate can corrode the secondary heat exchanger so it weeps. This is uncommon but serious and needs a professional assessment, not a patch.
What You Can Check Safely
Turn the furnace off at its switch and lay down towels. Identify the highest wet point — the trap, a hose connection, the pump reservoir, or the cabinet above (which would indicate the coil). The source usually reveals itself this way. Timing is another strong clue: a leak that shows up only when the air conditioning runs points to the coil above, while a heating-season or year-round leak points to the furnace's condensate system.
If there is a condensate pump, make sure it is plugged in and listen for it running; a full, silent reservoir is a clear sign it has failed or lost power. Look over the visible hoses for kinks, cracks, or slipped connections you can gently reattach, and check the trap is seated and intact. Wipe everything dry, then watch for a minute or two so you can judge whether the leak is still active or was a single overflow.
Leave the deeper work alone: do not pour chemicals into the drain, do not run the furnace with water near electrical parts, and do not open the burner or heat-exchanger sections — those are sealed, gas-side areas meant for a certified technician. If it is leaking more than a slow drip, shut it down and call 604-359-1081.
Why Prompt Repair Protects Your Home
Acidic condensate is hard on metal, so an ongoing Bryant furnace leak corrodes the cabinet base, rusts burners and the control board, and can damage the floor or the ceiling underneath. Given Greater Vancouver's damp conditions, trapped moisture around the furnace also encourages mold growth.
And there is a combustion-safety angle. Water collecting in the wrong spot can disturb the inducer or pressure switch and affect how the furnace burns. If you see a leak together with soot, a CO alarm, or a gas smell, treat it as an emergency — get everyone out and call FortisBC at 1-800-663-9911 or 911, then call us. For an ordinary condensate leak, fixing it early keeps the repair small and the floor dry.
Bryant Furnace Repair Across Greater Vancouver
Furnaces, including every Bryant and Carrier model, are serviced by our parent company, CanroHeat. Our Red Seal–certified technicians cover Vancouver, Burnaby, Surrey, Richmond, the Tri-Cities, New Westminster, and the North Shore. We clear and re-trap condensate drains, replace pumps and cracked tubing, service AC coil pans, and inspect heat exchangers, then confirm the unit is draining and venting properly before we finish.
Because repair cost depends on the cause, we diagnose first and provide an exact written price — no invented figures. We will also flag anything likely to cause the next leak, like a worn pump or a trap overdue for cleaning, so a small fix today does not become a bigger one next winter. Call 604-359-1081 for a quote specific to your Bryant furnace, or to book same-day or weekend service.
