Combustion issues can be a service technician’s most challenging and intimidating problem to diagnose. Unless you’re equipped with the proper skills to tackle these issues, it’s easy to become frustrated and just start guessing. I know because that’s exactly what I did for years. Fortunately, I learned there was a better way.
Tracking down combustion problems is like looking for a needle in a haystack. Unless you know where to look, you could spend days searching for something you’ll never find. Proper testing skills systematically give you a way to eliminate big chunks of the haystack until you’re left with a smaller area to focus on. It takes a specially trained HVAC technician to know how and which chunks to eliminate.
