It seems like common sense to seal off a room you rarely use so you don’t waste money cooling it. But it’s not the best idea.
If you seal off a room’s air conditioning registers and close the door, you can create extra pressure on your air conditioning system. That can actually cause air to leak through your ducts—and that’s a waste of air conditioning, energy and money.
A study by the Lawrence Berkeley National Laboratory proved that closing registers in unused rooms actually increased energy use throughout the home.
Plus, a hot room with too little air flow is a breeding ground for mold and mildew, which can ruin your furniture and create health problems.
If you are looking for ways to save money on your monthly utility bills, we recommend having an energy audit
preformed on your home.
