Do Closed Air Conditioning Vents Save Money?
We completely understand as a homeowner that you’re determined to try to do what you can to cut costs with one strategy being closing A/C 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. So, in short, don’t close your A/C vents! Here are some reasons why as well as what you CAN do to help your cooling system get better performance and efficiency.
Problems Caused by Closed A/C Vents
1. Carbon Monoxide Poisoning
The most sinister problem that can arise from closed air conditioning 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. 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 A/C ducts to tear and will exacerbate any pre-existing ductwork leaks. Keep your vents open to prevent damage to your ductwork. If ducts are not maintained, leaks will worsen over time — resulting in lost efficiency and costly repairs.
4. Mold
Closing A/C 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 A/C vents do the opposite for your system’s efficiency by causing it to work harder to cool your home. The pressure that builds from closed vents makes it harder for your air conditioning system to distribute the air therefore increasing energy costs and shortens the lifespan of your system.
What to do Instead of Closing A/C Vents
Schedule Regular Air Conditioning Maintenance
Preventive maintenance helps improve system efficiency, reduce energy costs, improve indoor air quality, and extend the lifespan of your air conditioning system.
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. Give us a call if you’re unsure how often you should change the filters for your specific system or what kind you need.

Clean Your AC Drain Line
The A/C drain line (condensate drain) removes the condensation that’s produced by your air conditioning system’s evaporator coil. If your AC drain line isn’t clean, mold and mildew can grow and create a blockage. A clogged A/C drain line can increase your home’s humidity and result in water damage to your home. Having a clean drain line will improve your system’s efficiency and ultimately save you money.
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 air conditioning work more efficiently.
