People tend to ask this question twice a year: When it’s freezing outside, and when it’s boiling. A lot of HVAC’s common questions are asked around those times. But this one has an easy answer that applies 7 days a week, 24 hours a day, 365 days a year:
Leave them open.
There are a few different reasons why this helps you:
Longer Lasting Efficiency of HVAC Systems
By leaving your vents closed, you can increase energy consumption and risk overworking your system ahead of its lifespan. Leaving the vents closed increases duct pressure because there are fewer places from which the air can escape, and the air becomes harder to move. With this increased pressure, the fan in you’re A/C unit will work harder than it needs to, so it can move that extra air through whatever openings are available, whether it’s the other vents or even the smallest cracks in the system.
Open Vents Mean Better Air Flow
By keeping your vents open around your house, even in the rooms you use less, the air flow in your home becomes more stable and consistent. This means you’ll be less likely to have to deal uneven temperatures throughout the house which will reduce your utility bill drastically.
Prevent Temperature Struggles
Due to the pressure build up caused by closed air vents, the slow air will struggle to fight heat and humidity like it otherwise could. This can cause a frost buildup on your refrigerant coil which, if left unchecked, can cause a massive ice buildup. This causes the fan to work harder and eventually burn out. The melting ice can then cause water damage. This issue is not as common, but it is one that you could easily avoid with the knowledge in this blog.
Cut Back on Chores
Another thing to consider is that your chore time could be made shorter and easier. You’ll have significantly less dust, mold and hair to keep track of and your air filter will last a bit longer.
When to close the air vents
There really isn’t a time when you should close any of the vents in your house, aside from an emergency where your HVAC system malfunctions and blows bad air or even smoke into your room. Keeping your vents open will help you lower your energy consumption and utility bill, while helping your HVAC system keep your home much more comfortable.
