RedDestroyer Gaming I’m not buying it, he’s obviously either wearing giant pimp shoes, in a custom made dwarves house, or riding on drones shoes! Occam’s razor, next you’ll ever telling me there is a frame shaped step ladders, don’t steal my idea! TM patent pending! Maybe he really is tall, but I come from family of really tall, sister is taller than me. That’s like 7’ 5” ? Mar fans syndrome or pituitary gigantism! It’s common sense! Oh, before you say it, it’s not stilts!
@@ViralRivers Yes it is. But the point is, that air is being diverted to the other supply registers and it's not going to damage the furnace/air handler.
Thanks I totally forgot about this minor adjustment to help divert more cool air upstairs. I had all the downstairs wide open. its a stupid simple thing that I didn't even think about. thanks!
thank you I am not from California and I am going crazy with the AC. I have 2 story house and I can't sleep at night is too hot and the downstairs is frozen ...
If you only closed a vent 50% does it make a difference or just have higher pressure coming out through the vent, vs the 85% you did in the example. Is 85% the recommend amount to see a noticeable difference? Thx
Closing to 85% is a horrific suggestion IMO. Start with ALL VENTS FULL OPEN. MAXIMUM CLOSURE = 45% ON 1/3RD OF THE DIFFUSERS. HOW MUCH did the TOTAL AIR FLOW RATE DECREASE?
I’m no pro but they say that messing with the register is not good because it will force the hvac. I will deff leave register open and mess with the dampers instead .
I'm new to forced air heat/ac and have a new home. I have three zones, two on the main floor and one downstairs. There's a big temperature difference from downstairs to upstairs....roughly 6-8 degrees. The downstairs zone was set to blow 20% into the main floor zone. Is that standard? We all know heat rises so why is there air blowing in a separate zone when you don't need it? I only have access to the registers with dampers.
then you just set you desired temperature on that one thermostat and find which rooms are hotter in the cooling season and which ones are colder in the heating season and see which ones you need to close
What if you have a 2 story and 1 unti controls 1/2 of the house up and down and the other unit controls the other 1/2 up and down? How do balance in that case?
If you turn downstairs off and feel no air coming out then you have dampers if you do feel air and even the thermostat being off then theres your issue..
I’ve been in commercial TAB work for 9 years. First off, a “balanced” HVAC system has nothing to do with temperature, it’s only the correct CFM / air transfer rates per room size. Always have at least one diffuser wide open, anything more is building more static pressure than an air handler is designer to do.
Don't you think the duct is designed to have adequate air flow to each room based on the location of the room and size of the room? If the design is right and the duct is installed correctly then, I believe all the registers should stay open all the time instead of adjusting the register opening /closing.
Ok so i have a multi-level house and only one thermostat, the basement is freezing and the upstairs is hot (where the thermostat is located). It’s causing a giant temperature difference throughout the house. What can i do??
Ok so I like my house cool but can’t stand freezing cold air because I’m very thin. My husband on the other hand doesn’t like me closing the vents 85%. He thinks I’m messing up the system. Wish this was an easy fix. It kinda is. Thankful I have air at least!
What if I have Thermastats in a 2 story home and leave upstairs off and leave thermostat downstairs on in winter? House is still very warm with upstairs thermostat off.
If you was to do that then you have the house equiptment to warm up your house in 30-45 mins but your choosing to take now 2hrs-to possible all day to just rely on the downstair vents to somepoint warm up upstairs (all doors open in the house) thats like choosing to drive 20mph on the highway but you have the capacity and availbility to go 65mph and get point a to be in minutes
Wait, I'm not here to disqualify this video by any means, but the correct way of balancing a home is by installing manual dampers. Installing manual dampers at the plenum, closing, or opening them at the plenum is truly the only way to balance a home correctly. Closing off registers is only going to create noise. Think about it: if the air has already reached its termination point at the register, it's not going to be pushed back through the ductwork just because one has closed off the register. Air simply doesn't work like that, especially with the air right behind it trying to exit as well. Air is like water; it travels to the path of least resistance. So, attacking it at the point of contact (when it's coming across the coil) is the best method balancing a home. But carry-on...
@@NoBody-ro3xjim curious is @aerialhearing wrong? I mean to some degree a really well built and insulated system is designed to have x number of vents open with hvac system operating at whatever efficiency level. I was told to leave them all basically open because system was built for that number if vents and returns etc. However, my issue was that the ductwork inbetween floors 1 and 2 would condensate so bad it would stain the paint on the dry wall around that same ductwork. I added a big vent in my garage making garage cooler and boom problem solved at least 85% less water bleeding through and staining paint. Any thoughts?
@@NoBody-ro3xjwas that a compliment or sarcastic statement meaning @aerialheating dont know what they talking about or more specifically there statement is completely not correct?
@@NoBody-ro3xjit wasnt for nothing if your comment was a negative one and you had things to say to back it up. I have heard alot of contradicting things from the professionals and have learned alot lately regarding hvac from peoples comments/you tube rather than the actual tech.
Home owners can't air balance and air balancing is done at dampers not registers. Changing system airflow at the register can cause damage to the system and drive up utility bills.
Nope, if you if you wanna try and fix that problem yourself cheaply would be to go out and buy a ecobee thermostat and use their wireless temp sensor and put it in your hottest room But professional help 1.theyll have to check blower fan speed 2.check pressures/refrigerant 3.check ductwork
Closing vents will help but youll eventually would want what your closing to be cold in there too..making your thermostat run longer and still have a hot spot
@@jacksongil9123 typically no..but if its a vent thats blows out hard then maybe but till take like 12 hrs for you to tell or it freezes up right away which ever comes first
Two thermostats means 2 different furnaces. Bad advice to lower the temperature in one system. Close all the doors to rooms ALL THE TIME and ensure there is a 1 inch gap between the bottom of the door and the floor surface. Change filter often. Make sure system is clean. A sealed system runs much more efficiently.
Can i ask why to have a one inch gap? I rent several rooms out in my house to people ans for noise control and privacy there isnt as much air passing through closed door and most normal people do or have. I ask also because i have two story house that really heats upstairs in summer and freezes downstairs more in winter and i have consistently used 30 percent more than comparable house around me that haven't had all kinds of energy or star whatever upgrades and thus are registered as energy efficient homes. It was also like this first couple years when it was just me and one other person. I was like dam all these other houses are families and i am still averaging 30 percent more than those comparable sized homes that werent energy certified?
@@nomoreliberties Do you have a gas powered forced air heating/ cooling (most people call it air conditioning) system with return vents in the hallways? And, are people opening their windows during the winter? And yes, heat rises while cold air falls. That is why the firemen tell you to lie on the floor to get cool and less smokey air and crawl your way to an exit.
Bad advice. Your system is meant to run with them all open. If you have a room or 2 that you need to shave off 10%-20%, that's one thing... but slamming them up to 85% closed... well, many things could go wrong at that point. ESPECIALLY since many homeowners have been sold over sized units by unknowledgeable salesmen. If you need to close them, then there is a bigger issue. OK, I just checked out your website, and you are NOT an Air Balance company! You don't even offer that service! You obviously don't understand what an Air Balance technician does, so stick with what you know!
Heidi S I disagree. The system needs to be engineered with a certain CFM designed for each room. Some rooms are bigger than others. Balancing dampers need to be used to achieve the correct airflow.
Our houses are designed by registered mechanical engineers in the state of Nevada. On our plans, there is a low and high CFM requirement depending on which way the house is facing. We wanted this video to be simple and easy for our homeowners to understand so we left out technical details such as this so as not to cause more confusion to our homeowners. Thank you for your concern and input. We appreciate it. :)
While greatly simplified, it's not nearly as bad as you say, Heidi. Also, by "Air Balance Companies", you probably mean a "certified air balance contractor". Those are generally only for commercial systems. You don't have to be one to give advice on residential systems. My only suggestion related to this video would be to caution homeowners that closing registers increases the total resistance in the duct system, which decreases total airflow. A well designed system can handle that, but most systems are not well designed. It sounds like these guys do a good job.
+Sierra LLC Air Conditioning & Heating so when the register dampers are 100% open, they are near the high cfm requirement; and when 85% - 100% closed, they are near the low cfm requirement?
Sheesh what a waste of a video. I expected a video to go into how the ducts in the house ventilates the air in the home. This is an example of how to move the vents in your car to face you for more cold air to vent to your direction. Video can be summed in one second. Close vents. Lol.
Nice video BUT very very misleading statement in there about the duct not being fully closed is better! Any long time HVAC tech, or physicist for that matter, will tell you, and knows, that air like water follows the path of least resistance!!! Meaning either fully opened or fully closed is best. If you only close it 85% then the flaps are at a weird angle and sticking in a direction that will in fact deflect the air the other way and have the opposite affect of what you're trying to achieve. So basically does the opposite of what this video claims which is what you actually WANT to happen. If you want the upstairs to get cool air in summer,simply close as many vents on the first floor as possible. The first floor will still get plenty of air. And the thermostat is on the first floor so if it is 70 on the first floor but 85 upstairs it will shut off and the upstairs remains hot. so by closing off all vents downstairs the thermostat will get a better reading and a more level and comfortable temperature throughout the home
