A Loud Condensate Pump and a Filter Nobody Had Checked: Both Replaced

A Barrie homeowner called us about an unusually loud noise coming from their furnace’s condensate pump. Our technician confirmed the pump was faulty and replaced it. While the American Standard furnace was open, he also found an air filter so clogged with dust that it had to go too.

The Problem

When the Condensate Pump Gets Noisy

A high-efficiency furnace makes water as it runs, and the condensate pump is what carries that water away to a drain. It usually hums along quietly. This one had become unusually loud, and that’s what prompted the call.

On inspection, our technician found the noise came from a mechanical problem inside the pump itself. It wasn’t something a cleaning would fix, so the pump needed replacing.

The Repair

Swapping Out the Faulty Condensate Pump

We took the defective pump out and installed a new condensate removal pump in its place. The old unit, shown here, is stained from use.

The new pump took care of the noise the homeowner had called about.

The Extra Finding

An Air Filter Packed With Dust

Since the furnace was already open, our technician checked the air filter. It was extremely dirty, with the pleats heavily clogged by dust and debris.

That matters more than it looks. A filter this blocked restricts airflow through the furnace, cuts heating efficiency and puts extra strain on the whole HVAC system. It’s also easy to miss, because nothing about it makes noise.

The Result

A New Filter and a Quieter Furnace

We removed the old filter and put a new one in, so the furnace now pulls air through a clean filter again.
