Thinking about shutting vents in rooms you don’t use to save on heating? Turns out, that move could backfire. HVAC pros say closing vents actually makes your furnace work harder, risking pricey repairs and uneven temps. Instead, try lowering your thermostat, sealing drafts, or using a space heater where you hang out most. Your wallet—and your heating system—will thank you! #Business #Industry #HomeHacks
