Does Closing Air Vents Save Money?

Like most fiscally responsible homeowners, you’re determined to try new things in order to cut costs. Perhaps you’ve considered a new way to cut energy costs by closing AC vents in unused rooms. While doing so may seem like a logical measure to take — it can actually create many problems — including increased energy bills. But, what kind of problems do closed AC vents cause? Does closing air vents save money? And, what can you do instead to save money while improving AC efficiency? Here’s what you need to know.

5 Problems Caused by Closed AC Vents

1. Carbon Monoxide Poisoning

The most sinister problem that can arise from closed AC  vents is carbon monoxide poisoning. Closing the vents can cause your system’s heat exchanger to crack — which can release carbon monoxide gas into your home. Carbon monoxide is a colorless, odorless, tasteless gas that deprives the heart, brain, and other vital organs of oxygen — which is what makes it so deadly. If you need one good reason to keep your air vents open, this is it.

2. Frequent Repairs

Closed vents restrict airflow — which causes your system to work harder than it was designed to. The restricted airflow also causes problems like a frozen evaporator coil and damage to the compressor  — resulting in costly repairs. Ensure the health and lifespan of your system by keeping air vents open and unobstructed at all times.

3. Damaged Ductwork

The increased pressure that forms from the restricted airflow can cause your ductwork to burst. The pressure causes AC ducts to tear and will exacerbate any pre-existing ductwork leaks. Keep your vents open to prevent damage to your ductwork and remember to have your AC ducts regularly maintained. If you do not maintain AC ducts, leaks will worsen over time — resulting in lost efficiency and costly repairs.

4. Mold

Closing AC vents create condensation in your ducts — which increases the risk of mold. Ensure air vents are kept open at all times to prevent mold growth and protect your home’s indoor air quality.

5. Lost Efficiency

While you may have heard that closing air vents in unused rooms can improve efficiency — this couldn’t be farther from the truth. The fact is, closed AC vents do the opposite for your system’s efficiency by causing your AC to work harder to cool your home. The pressure that builds from closed vents makes it harder for your AC to distribute the air — which increases energy costs and shortens the lifespan of your system.

What to do Instead of Closing AC Vents

Schedule Regular AC Maintenance

Preventive maintenance helps improve system efficiency, reduce energy costs, improve indoor air quality, and extend the lifespan of your AC. Check out our AC maintenance checklist to learn more.

Change Your Air Filters

While we recommend changing your air filters once per month, there are other factors that can influence how often you should change them. Learn more about how often to change your air filters.

Clean Your AC Drain Line

The AC drain line — or condensate drain — removes the condensation that’s produced by your AC’s evaporator coil. If your AC drain line isn’t clean, mold and mildew can grow and create a blockage. A clogged AC drain line can increase your home’s humidity and result in water damage to your home. Taking the time to clean your AC’s drain line can improve your system’s efficiency and ultimately save you money. Learn how to clean your AC drain line in six steps.

Upgrade to a Programmable or Smart Thermostat

Programmable and smart thermostats offer many benefits, including increased comfort, reduced energy bills, and the ability to schedule temperature adjustments — all of which help your AC work more efficiently.
