Tools of the trade 🤟🏼💯 If you do not have a combustion analyzer and are tasked with the install and/or service of gas burning appliances like furnaces and boilers then get one and get some training on how to use it. It’s not scary, it’s not hard. No one will judge you for wanting to learn. We only judge you for using crap tools and wearing that ugly jacket. Where’d you get that jacket, a dumpster? While you’re at it, get a new jacket weirdo. This ain’t the circus. #auneplumbing #hvactech #hva
