Ductwork in an attic is crazy even when installed well.
Thanks Dad. :cheers:
Grass is wet in the morning. Cool air can't hold as much water.
Air leaving an ac unit is cool and clammy.

Insure only things you can't overcome loosing. Look at all the insurance folk and their lifestyle. That's how they live with what's leftover after all the claims are paid. Keep insurance to the...
With three of them burning like that maybe sabotage? I'm not familiar with those systems but it just seems odd they all burned similar.
If you feel a slight tingling sensation ANYWHERE you are prolly infested...:grin2:
Contact cement glue for duct liner.
It's not normal practice around here. The first piece of duct with liner usually gets metal nosing to keep the air from peeling it off. If the problem will...
So how goes the slum lording?

Just looked at the location and it is surprising they have an ammonia system in the middle of such a congested area. Im sure...
That is a tragedy and I am sorry for the workers family. Just wonder what happened to rupture the 1 1/2" pipe. The fireman saying the location of the shut off valve caused this is not a...
Those things are nasty. My father worked for Ralston Purina and they always had problems with them tearing up stuff and pooping on stuff. He got a permit to shoot them right in the middle of town. ...
Sorry to hear this. I hope you can find peace and comfort in your remaining time.
I respect any guy who gets up and goes to work every day, whatever he does. Different folks have different skills and enjoy different types of work. Not a thing wrong with doing residential or...
It's capitalism....
Everybody wants to make as much as they can. Companies like carrier will build stuff in the USA when it's more profitable to do so. I don't like it, but what would work...
I may just go shirtless with purple body paint...:D
That would not be pretty...
Going to find something purple tomorrow.
God bless you sir.
Why is it so hard to get in?
$4500 for a dsc1212? That's crazy, we get $7500 for those guys and that's the low end....
And...I don't know what a dsc1212 is either...:grin2:

Dang Loonie. Sorry to hear you have been having trouble. Glad you got fixed up. :cheers:
This was not directed at you.
Just went to a medical clinic last week that had 2x the amount of cooling they needed. There were about 50 folks in there and the only complaint was in a room they...
Really, once you do a few calcs...you kind of know what it's going to take to cool a house that is built like every other one in the hood You've been working in for a while.

Hey Brett. Hang in there brother!
A fan will always move more air with less resistance, aka static. A fan will always use more power when it moves more air. So, a fan will use more power with less resistance.

Hope you heal up fast. My doc started telling me to get a shingle shot every year. How much does the shot cost with no insurance help?
I would not worry with a pressure monitor on a resi filter. Just look at them every 3 or 4 months and replace if dirty.
Hey, I already looked for some curve images. :cheers:
What you usually see is a different curve for the same fan at different speeds. You can usually use the fan laws to predict what will happen...
I'd like to see those fan curves...
Its difficult to accurately measure airflow. Checking static with a fan chart is a fast way to check it. I would trust the static method more than a traverse in a bad spot. A good spot being a...

There are companies that make a system to do this for large flow rates. It is a v shaped dam that has a light sensor measuring how deep the sewage is in the pit. It gets deeper with higher flow. I...

If the vent goes through an unconditioned attic it should be b vent. I don't think it will pass inspection. It's not really a fire hazard. Just don't want the fumes condensing in the pipe and...

Hey Brett, I'm taking my girls to unc Friday for the next school year. Hope you get a good report.
Well, you can read the pressure drop across the circuit setter. Would think you would be able to see if its restricting. Is the problem the air is not getting cooled down? Is the entering water...
A few guys met at a shooting range a while back and just shot some targets and hung out one afternoon then had supper together. Sounded like they had a fine time.
Guys like you aint got no business "retiring". You got to much knowledge to keep a lid on it. Get your fanny to a supply house! They need guys like you.
Ive been fortunate to visit two "labs" where they put white smoke in ducts so you could see what the supply air does when it leave the diffuser. 3/4ths of it is heading the other way. The fourth...
My experience has shown me the opposite. Really doesnt matter if supply and returns are right next to each other, IF THE SUPPLY DIFFUSERS ARE PROPERLY SIZED.
Look at a concentric duct package. ...
Just read your post a little closer and i see you dont have enough flow. Is there anything unusual about this unit verses the other 21? Is it higher than the others? If you momentarily valve off...
Is there a preheat coil that is heating the air up before it hits the chilled water coil?
If you have verified you have the correct chilled water flow going through the coil, you need to look at...
Im guessing the inspector failed the final because the switches "did not have proper clearance". Electrician made the first disconnects junction boxes.
