Because modern energy-efficiency upgrades (such as air sealing and insulation) alter a home's pressure dynamics, understanding how combustion appliances interact with the "house-as-a-system" is critical. This training teaches professionals how to identify life-safety hazards, mitigate carbon monoxide risks, and perform industry-standard diagnostic testing.
