PTAC Air Conditioning Unit - Excessive Condensation Question

Hi Everyone,

About a month ago I replaced my PTAC air condition unit in my tenants apartment with a new one. The company I used replaced it with an Ice Air unit. My tenant stated that for the past couple of days after running the unit throughout the night that she is seeing excessive condensation on the grill (pictures as of this morning attached).

When I lived in that same apartment with the old unit I would also see some condensation here and there when I would wake up in the morning after running the AC unit all night.

Is this normal or would you recommend I request a service call? I appreciate your feedback.

If it is only a month old I would call the installer and see what they say.

Thanks Geochurchi. I've called them to come revisit the unit. I'll keep everyone posted with any updates.

It would be normal to have condensation on the discharge grill if the humidity were very high.
One thing that would reduce condensation was if you operated the a/c on high fan as opposed to low as shown in your picture.
High fan would raise the supply air temperature.

It would also condense less if the unit were to run for a long enough time to reduce the humidity in the space.
You will get less condensation if you operate the a/c to lower the humidity then leave it running in hot weather so that it doesn't have to remove moisture each time you turn it on and off.
Instead of turning it off, lower the temperature slightly when away or at night.

It does use a bit more power to run continuously but not as much as you would think. Because removing moisture from the air takes as much as half of the cooling power and would not

You should not be seeing any type of condensation. We work on these units all the time here in Tampa and I can tell you that when I see those, i actually recommend replacing them

High RH in the space, or unit is not draining.
