🛠️ HVAC Depot Pro Tip: Inspect Tubing & Venting First

Before replacing a furnace pressure switch, inspect the rubber tubing, condensate drains, and vent piping for blockages or moisture buildup. Many pressure switch faults are caused by restricted airflow or clogged ports rather than a failed switch itself. Always verify inducer motor operation and pressure tubing integrity during diagnosis.
