Combustion Analysis
Combustion Analysis is a safety and efficiency check that HVAC technicians perform on heating systems like furnaces and boilers. It's like giving the heating system a health checkup to make sure it's running safely and using fuel efficiently. Technicians use special testing equipment to measure how well the system is burning fuel and check if any harmful gases are being produced. This is an important skill because it helps prevent safety hazards like carbon monoxide leaks and ensures customers aren't wasting money on high fuel bills. You might also see this called "combustion testing," "flue gas analysis," or "combustion efficiency testing."
