What Do I Do about Excessive Condensation Issues with my Air Handler? - Ask the Expert Episode 223

I have the same problem, same size equipment and house. My installer re-used the old drain pipe, I finally ran drano through it to make the problem stop. The copper pipe was also reused and has a pinhole so I also have the problem of replacing the pipe and coolant to deal with.

Hi I am the person who posted this question initially and have had multiple “pros” come to look at my problem they all have tunnel vision and go straight to the drain line and add a vent or take one out or add a larger “p” trap which seems to be a common problem. Not mine. I am producing more condensation than can be drains out and is blowing around inside the air handler which is going to shorten the life and cause many other problems down the road. Please any help would be appreciated. Sincerely Dino Canale

Where can I buy new batteries fo my MrCool 250 Btu air conditioner remote control?

The condensate line into the ac condenser unit is clear, the p-trap and the line out is clear but the pan keeps filling with water. I drain the pan of all the water and it runs for a few days and than the pan fills up again with water shutting the unit down. What else do I need to check?

Reading through this condensation issue. While it appears that the horizontal system sizing (tonnage) was adequate in generating condensate lets step back. Like others noted: Your Physical location was not noted however its humid. A typical 2.5 ton system operating with an indoor air temp setting of 78 degrees could generate a quart of condensate every 30 minutes Starting with an indoor humidity of 75%. With the statement of “Condensate is blowing around the inside of the coil enclosure” This condition can occur for a number of reasons. 1) Coil is not Securely mounted level or slightly pitched to the factory drain plugs. 2) Did you consider running Two separate Drain lines of 3/4” so that the primary and secondary drain ports relieve condensate development. 3) Did the manufacturer provide any internal air deflector necessary for horizontal application? Confirm Refrigerant coil and blower Installation per the manufacturers instructions. 4) If the refrigerant coil is a multiposition Type, was the Internal upflow position drain pan removed for unconditional airflow without obstruction? 5) What is the downstream ductwork or plenum configuration downstream of the full size outlet of the coil? Any abrupt Directional change or fitting takeoff on the plenum can generate airflow Obstructions contributing to the disturbing condensate water turbidity within the drain pan. 5) Make sure the coil connections and ductwork are well insulatec with foul taped joints ensuring that the condensate leakage is truly internal vs external sweating.

The question i have is or has not been sighted as a problem yet but i am concerned about there being way too much condensate coming from this unit. All condensate is coming to the ground. Could there be an under lying problem in some way with the unit? I may be just a worry wort but could there be a cause for excessive drain water. The condensate from the outside unit 6 ft. away produces about 1/3 of the condensate. The units are a 3 ton and a 4 ton. Thanks in advance for your assistance.

We have a Goodman ( new last Nov.) and have that same problem....service guy decided to insulate it more inside of the handler....but it still is sweating.

I have a 2 ton 24 btu from Mr.Cool It is draining fron the inside unit, also on to floor underneath, it's brand new so nothing stopping up ro kinked, no drain pain under some of the pipes, and suggestions
