Why You Should Open All Your Vents
Has anyone ever told you to close certain vents in your home during the winter and open others during the summer? Or that you should close the vents in rooms where you don’t want to pay for the heat or cooling?
Unfortunately, lots of people have reasons for closing their vents but most of them aren’t good for your system, house, or wallet. In this article, we'll talk about how opening your vents can help you get more out of your heating and cooling system and prevent problems.
Help your heating and cooling systems last longer
The best reason to open your vents is to help your heating and cooling systems last longer. Keeping your vents open prevents overheating and freezing in your furnace and air conditioner. Moving furniture a couple inches away from vents also makes a big difference.
On the flip side, when you close your vents, it creates excess pressure in the ductwork and the furnace. For the system to function well, the motors would have to work many times harder than normal when they’re closed.
Save yourself money
Whether your vents are open or closed, your heating and cooling system will try to move the amount of air it was designed to. Some people think closing vents will save them money because they won’t be heating or cooling rooms they don’t use. But the opposite is true.
By closing the vents, you’re not only not saving money, you’re spending more money. That's because it's shortening the life of key components and the overall life of the system.
Reduce hot and cold spots in your house
Here is the basic concept of a heating and cooling system: Air goes into your return vents and comes out your supply vents. When air can travel freely in and out of your system, the temperature in your home is more even, which reduces hot and cold spots.
If vents or doors block the circulation of air, those rooms cannot change temperature at the same rate. Closed vents mean big temperature changes from room to room.
Closing a Vent Doesn’t Direct the Air to Another Room
The ductwork in your house is like a tree. The trunk of the tree is the air handler, furnace and evaporator coil. The large return air vents are the roots, drawing air into the system to fuel the trunk. The supply vents are the branches, where the trunk is pushing air out to the house and making your home feel nice.
Some people think that closing vents will direct more air into other rooms, but because the branches are not connected to each other at the ends, this logic doesn’t work. Closing vents only suffocates the system and costs you money, since you’ll have to replace the heating and cooling system sooner.
So, you know why opening your vents helps your home, wallet and system. Now what?
Take some time to walk around your home and open your vents. Move furniture a couple inches away from wall vents, move rugs off floor vents. If you can't reach a vent, they seem stuck closed, or you have mobility issues, ask your trusted heating and cooling technician to help you during your annual tune up.
