Do I need a condensate pump for my furnace?

Most furnaces in Ottawa don't need a condensate pump, but high-efficiency furnaces (90%+ AFUE) do produce condensate that needs proper drainage. Whether you need a pump depends on your furnace type and basement layout.

High-efficiency condensing furnaces create water as a byproduct of the heating process. This condensate typically drains by gravity through a plastic tube to a floor drain, utility sink, or sump pit. You'll only need a condensate pump if your furnace is located where gravity drainage isn't possible - for example, if your furnace sits below the level of available drains or if the nearest drain is too far away for gravity flow.

Standard efficiency furnaces (80% AFUE and below) don't produce condensate during normal operation, so they don't require any drainage system. However, if you're upgrading from an older furnace to a high-efficiency model, your HVAC contractor will need to plan for condensate removal as part of the installation.

In Ottawa's climate, proper condensate drainage is crucial because high-efficiency furnaces run frequently during our cold winters. A failed or inadequate drainage system can cause water damage, frozen drain lines, or furnace shutdowns. If your basement floor drain is more than 25 feet away or sits higher than your furnace, a condensate pump (typically $150-$300 installed) ensures reliable drainage.

Safety note: Condensate drainage must be installed according to TSSA requirements and local building codes. Improper drainage can cause carbon monoxide issues or equipment damage. Always have a licensed HVAC technician assess your specific situation during furnace installation or replacement.
