I don’t think it’s a code but it’s Necessary to have a drain pan when you’re installing a system in the attic, The code is only for drain to be connected to the sink and overflow on top of a window or a door
Hey guys I’m 23 years old and I’m 5 months in on my HVAC career but I have a question how do you determine the size of the return and supply plenum? I asked other people I worked with and some say they don’t know others just don’t want to tell me
You have to calculate the return and supply duct size based on the CFM of the unit. For example, if you have a 2 Ton system which is 800 CFM, you calculate the size of the duct based on 800 CFM, And you will need a duct design calculator, to find what size of duct you will need to give you 800 CFM return and supply, I hope that helps God bless
@waisHVAC no you can install it there, sure. It's just a horribly inefficient place to put an air handler and ductwork. Modern efficient design practices always place the air handler and ducts within the building envelope. And from an installers point of view, would you rather service a unit in the attic or inside the living space?
Efficiency nothing to do where you installing the system? to measure the efficiency of central air conditioning and heat pumps. It's calculated by dividing the total cooling output (in BTUs) by the total electric energy input (in watt-hours) over a typical cooling season,
Well you earned a like and im subscribing to this channel right now 🤙 Keep up the good work Sir.
Nice and thanks - noise of course! what kind of the anchor nut you used? is it like swing?
Why don’t you use impact drill with socket attachment for the lag bolts??
Unfortunately I don’t had the socket box with me that day, I know it was annoying to tight the lag bolts with wrench,
Is it code to put the secondary drain pan in? Do you need that if the mechanical is on main the floor?

It is CA code required for sure
Where is the auxiliary pan?
Under the Air handler
What is the name of the tool u use to get the air handler up in the attic?
It’s a genie lift and it works With nitrogen or air compressor
@@waisHVAC nice 👍

No auxiliary drain
Sir I am air conditioner duct fitter you have vacancy I am experience 15 years in Gulf country kuwait
Well you should have started with telling folks to never locate an air handler in the attic of new construction.
I am not sure where you got this information from ? that you can not install air handler in the new construction?
