Tools of the Trade: Smoke Puffer/Smoke Pencil
Ever wonder exactly where that draft is coming from? Whether you’re an HVAC tech, energy rater, or just a DIYer trying to seal up a leaky home, a smoke pencil/puffer is an absolute game changer. Smoke puffers are great to use for troubleshooting, especially because it gives a steady stream and is easy to carry in the toolbag.
Unlike those old-school smoke candles that make a huge mess, these little puffers create a clean, non-toxic v***r that lets you see exactly what the air is doing in real-time. It makes it so easy to find leaks in ductwork or pinpoint exactly which part of a window or door is letting the air in. It can also be used to check for negative pressure or just to visualize how the air is balancing out in a room. Another positive is that this is a troubleshooting tool that is portable enough to live in a toolbag.
