“I’m not gonna make it … You go on, leave me behind!”
You’ve probably heard dramatic words like these spoken in many movies and TV shows. What do the heroes usually do in such extreme cases? They pick up their friend and carry them onward, refusing to let them expire.
If, however, it’s your home furnace that’s telling you “I’m not gonna make it to the end of winter … You go on without me!”, then you should probably just say, “Okay!” and have a new furnace put in. You don’t have an audience watching who’ll be disappointed because of an emotional attachment to the furnace.
