Boiler Air Pressure Switch Replacement in Greater Vancouver
Confirms safe airflow and venting before the burner lights. Supplied and professionally installed by licensed gas fitters — never sold for DIY.
What the Air Pressure Switch Does
The air pressure switch proves the combustion fan is moving air and the flue is clear before the control allows ignition. A failed switch or blocked sensing tube is a frequent cause of no-heat lockouts.
It senses the pressure difference created by the running fan; only when the correct draft is proven does it close its contacts and let the ignition sequence proceed.
We supply and fit the air pressure switch as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
