Can You Save Money From Closing Air Vents?

We love to be able to save our customers money! When we perform home energy audits across the city of Jacksonville, we help homeowners uncover opportunities to reduce energy usage and related bills. What about air vents, though? There is often a lot of confusion as to whether or not you should be closing up air vents in certain unused rooms. Is this practice that you should act upon routinely?

Air Vents in Every Room

If you have an air conditioning or forced hot air heating system, chances are you have air ducts everywhere! Each room of the household will have a duct to allow the cold or warm air to blow in. What if there are rooms that you never enter? You probably have thought about closing up those vents to reduce air flow. The idea here is that you would save money, right? You may not be as spot-on accurate as you think!

The Case to Keep Air Vents Open

You want always to be sure that your air vents are open. Closing off vents in individual rooms is not a trick to saving money! Damage may arise from closing air vents.

Keeping air vents open is going to help with the entire ventilation of the home. When you close air vents, you are not going to be able to stop all air flow completely. What closing the vents will do, though, is put added pressure on the entire ventilation system!

Increase in Pressure

What will happen when you close up air vents is that you will put more pressure on the system! If you have a heater or an air conditioning system that uses a variable-speed blower, increased air pressure means more power used. The blower will have to put more force into what it is doing and utilize more energy than if all vents were open.

If you are an HVAC owner with a single-speed blower, you are also out of luck. A single-speed blower will reduce air flow, stopping it from moving around. Rooms with open vents will not have adequate airflow to keep them comfortable.

More Damaging Side Effects

Closing air vents can result in even more damaging side effects. Frozen evaporator coils and leaks in the air ducts are just a few! The biggest of all is that you could do permanent damage to your compressor, resulting in a costly repair bill or even a need for replacement.

Our home energy audit professionals in Jacksonville, FL want to save you money. We also want to try and erase many of the myths that exist with HVAC systems. One myth, closing air vents to save money, hopefully, has been laid to rest. Keep those air vents open because closing them could result in increased energy usage and
actual damage to your HVAC system!

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
