Thanks for the free video. Glad your members get to see the most important stuff. Just know that on my iPad, there is no way to join and be a member. All I see is the subscribe button. And I’m sure most people are in the same boat who click a video only to find out that the main info is behind a paywall that they can’t get to.

Hey that's awesome! I was like #300 I should get a free hat or something 🤔 love the videos man! I know your doing the fellow hvac man a lot of good service by this video. I personally learn better through videos rather than reading books, thanks for being that somebody who is teaching this way

And I’m not the only one feels this way what a tease

someone related to flow.. was redoing the ductwork in an older home that had a newer furnace/ac. I asked the tech to clean the coil while we had the unit disconnected and when he pulled it out, to my surprise we found the installation manual laying there right on top of the coil, blocking flow. Guys, always check the new unit and remove foreign paperwork!

That 8.5x11 manual had been there for a few years!

Can you make a video that compares a few common flex duct brands. Maybe include what can be found at big box stores vs HAVC supply houses.

What size should my trunk line be? Also can one boiler control two air handlers?

[devindailey]

I'm just got my Hvac License in Ga. I familiar with duct sizing. But I want to get much better and use in every job. Whats your recommendation

How do I know the maximum airflow, CFM, that can be handled by some 6” flex duct I have in my attic, if I put in a booster fan to be able to increase aire flow at certain times? The duct says 4000 FPM maximum, it’s 6” duct and I’ve got about 15’ of duct run before the booster fan and then 15’ after the fan to the vent? The fan at top speed says it puts out 400 CFM. Thanks in advance for any help on this.

Thanks for making these kind of videos. I have a 5 ton package unit that I have to install. Can I apply this knowledge to a 5 ton package system as it relates to the duct work I need for it?

Is there a formula for an air return duct size in relation to the supply size in a small sealed room? In other words I will be supplying a room with 2- 6" ducts. What should the return air size be?

I got 4 7” and a 8” and 1 5” vent attach to my plenum in a 750 square feet camp is that good r bad? It’s a wide open camp no ceiling

Hey, I’m a member. Do you have a video on return sizing for a 3 ton unit ?

[michaelmixon]

Question, i have less than 900 square ft home i was given a carrier 3.5 coil with heater blower. i was told that a 3.5 is too big for my home. and i should use a 2.5. i now have a 2.5 condenser by carrier. the house has 2 br, bath, kit, living room and a dinning room off the kit. in the hallway i only have room to access the attice there is no place for a large return. i am told i should put the returns in the ling room and bed room. i am doing the install by myself. what size vents and ducts should i use. i know the coil and condenser don't match. but which is better the coil being bigger or or smaller?

Hello, How would you calculate a mobile home split system with an inside down flow air handler 3 ton . No return . The Mobile home is 16X80 single wide with 8 vents total. The original duct is the rectangular sheet metal, and it is degrading.The mobile home is 1999 model . The local supply shops do not have the sheet metal available & I am considering using Flex duct & I am not sure what size or may I even use flex duct in replacing the sheet metal .
Thank you
