How do you fix that? Add more vents? Or turn the fan speed down?

Is just one stand pipe supposed to be capped off? When I pull the cap off it ***** water out of the trap.

If your cfm is to high it will pull the water off the coil instead of letting it drip into the pan. This becomes more of a problem when the unit is horizontal. It is accumulating in the supply plenum. When the Unit shuts off, the water will want drain out out through any seam. It is also putting some humidity right back in the shop. The open vent for the condesate drain should be after the trap, which it looks like it is. The one with the cap on it is a clean out. That cap needs to be on there . It also looks like you have a saftey switch on your internal pan. If the pan was backing up, this should shut the unit down. If your blower is a set speed motor, you may be able to wire it to a lower speed. You will have to take the cover off. If it is a 3 speed, it will have a black, blue and red. Black .being the highest and red the lowest.

So is this a problem or not really? It controls the humidity in the shop just fine. I don't really want to lower the fan speed.

Like is the unit going to get messed up over time due to this?

Yes. Over time, the water will increase the rate at which the steel corrodes. On top of that, there is probably a thin layer of insulation inside the air handler that can trap the condensate that doesn’t all run out, promoting the growth of mold.Like is the unit going to get messed up over time due to this?

It is hard to diagnose over the internet on something like this. But it is not right or good for not fixing the problem. I would think that over time, it will cause more problems. You are putting humidity back in the building. If this is issue is caused by to much air flow across the coil, then you are not correctly removing the humidity in the first place. It sounds like this is the first cooling season that this unit has ran. I dont understand why you will not call back the person that installed it. Without the correct air flow, you can not even properly check the charge. First you have to get the CFM dialed in. This is done by measuring static pressure and using the engineering data that came with the unit to calculate CFM. or using a anemometer, unless you are in the trade, theses are not common instruments for a homeowner to have. I did forget to mention in my prior post, If the fan speed is lowered, it may affect the charge. So that needs to be checked also after lowering the speed. A delta T measurement will also help tell what is going on. If this was my unit, I would fix it. I will say it again, you can not properly charge a unit until you have the correct air flow across the evaporator.So is this a problem or not really? It controls the humidity in the shop just fine. I don't really want to lower the fan speed.

Never noticed it doing this back in June when it was 100 outside.

The only other thing that i could think of it being is if the duct is sweating, but you would be able to notice it. And it would drip while the unit is running, not just when it shuts off.

It does drip when running. More so on the outlet side.

Is the duct sweating, is the outside of the duct wet. You should be able to tell the difference whether the duct is sweating or water is just running out at the tapeIt does drip when running. More so on the outlet side.

It doesn't matter when it started. What matters is that you have a issue now. we have given you all possible reasons what could be causing this. We have given you solutions to fix it also. I just don't understand why you don't have the installer come back and take care of it. A brand new unit should not be doing this. Why did you have the charge checked a month ago. Was refrigerant added? or removed? Have you checked the humidity in your shop. You are not making sense, you say in your first post that it is dripping out of the end by the coil, which is the return end. But your pictures show it dripping at the supply plenum.I still don't understand why it didn't have qn issue all summer and now it is.

I'll have the installer come back out. I had them check the charge a month ago because they didn't check it when it was first installed due to it being like 68 degrees outside at the time.

One last question. Are you supposed to refill the trap with water after you clean it out or does it fill by itself?
Terry D

Either way, but it would not hurt just to fill it yourself. Pour some water down the pipe with the cap on itOne last question. Are you supposed to refill the trap with water after you clean it out or does it fill by itself?

I did that yesterday and after that it didn't sound like a bunch of water gurgling around inside the air handler. Maybe it has to run longer.

Yor pics tell the whole story. The trap on the main drain is REALLY shallow and pitched down. It's not allowing normal drainage when the blower is on. That's why all the dripping into the emergency pan doesn start or gets worse until after blower shut down. The auxillary drain is not supposed to be plugged, either. It should have a separate drain or be tied into the emergency pan drain and the exit for both should be where you can readily see it to notifiy you of an overflow. The primary safety switch is also supposed to be on the main drain, not the aux like yours is.

I see what you are saying about the trap, not to much of a trap at that angle, but how would this cause water to accumulate and drip out of the supply plenum instead of dripping at the evaporator area.Yor pics tell the whole story.

It hasn't been doing it lately since it has shorter cycle times. Only when it runs for a long time.

Do you think the shallow trap is the issue? I thought that trap is supposed to be full of water? When I take the cap off it just has a little at the bottom trickling out.

Although LS6Tommy has not weighed back in, he may be thinking that the trap is too shallow to work as a trap, and the air handler suction is interfering with the condensate out flow, thus causing it to spill into the supply plenum.

Yep. Seen it moretimes than I can count. I won't even use those heat formed traps. I always build them up with PVC fittings, or just use a good EZ Trap if the space and funds allow.Although LS6Tommy has not weighed back in, he may be thinking that the trap is too shallow to work as a trap, and the air handler suction is interfering with the condensate out flow, thus causing it to spill into the supply plenum.

UPDATE: I had the people that installed it come out and take a look and had them take the panel off. The tech noticed the splash shield was sitting kind of low so he propped it up so it would drain off better. His theory after me telling him where it typically leaks and him feeling around was that the water was pooling up and getting blown off the little extension splash shield pan. It was wet right below the pan and nowhere else. That was exactly where it was leaking out of the air handler too. Time will tell if this fixes it. It hasn't been leaking much now that the weather is cooler, but I'm going to run the piss out of it today and check back tonight to see if it starts putting water in the pan.
