The Lennox furnace pressure switch is a safety device that confirms proper airflow and draft before the furnace ignites. It monitors pressure changes created by the inducer motor and signals the control board to allow or stop ignition. If the switch does not close or open correctly, the furnace will not start or may shut down during operation. Problems usually occur due to clogged vent tubes, a faulty inducer motor, damaged wiring, or a defective switch diaphragm. The Lennox furnace pressure switch ensures safe combustion and proper venting of exhaust gases. Identifying these faults and fixing the exact cause helps restore normal furnace operation and prevents system failure.

As summer temperatures rise across the United States, air conditioners play a critical role in keeping homes comfortable and safe. However, proposed tariff changes could increase the cost of cooling equipment at a time when demand is already high. Industry organizations have expressed concerns about the potential impact on both contractors and consumers. The Air Conditioning Contractors of America (ACCA) noted that the change could significantly increase equipment costs, while HVAC distributor association HARDI indicated that some imported HVAC equipment could face tariff-related costs approaching an estimated 25% of a unit's value. Because many air conditioners rely on globally sourced components, higher import costs could eventually contribute to higher prices for homeowners.
