We live in an age of the “do-it-yourselfer.” You only need to type a few words into a search engine about any project you’re considering taking on, and you’ll be zapped to a set of videos offering to show you how you can do it.
But there’s a big difference between a video telling you that you can do something and whether you can actually do it. Would you trust DIY instructions on how to fly a plane? Perform heart surgery? Of course, you wouldn’t. And you shouldn’t trust DIY instructions for when it comes to fixing a broken gas furnace. We know it’s tempting to attempt to save money by tackling a faulty heating system on your own. But you absolutely shouldn’t.
