Fame
Fame for an HVACR is probably limited to local interests. No worries about a national tabloid flying a drone over your backyard to get pictures of you practicing yoga. (Nice form, though.)
Want fame? Try being the person who gets the heat going just in time to save a local elementary school's Winter Carnival. Then again, if you design an energy-saving system that gives climate comfort year around while saving your client a lot of money, some fame will naturally come your way, though it'll probably be the local, word-of-mouth variety.
