Excessive AC Condensation Problem This morning's Warranty Inspection had a situation I have not encountered before and I would like some input on it. The weather this morning was low 80s with scattered rain. It has been a particularly wet and humid summer here. When I walked in I noticed that it was pretty cold in the house. My wife likes to keep it pretty cool at home so I am used to 74 or so temps. This was uncomfortably COLD to me. When I got to the thermostat it was holding steady at 65. When I got to the attic to look at the unit, I noticed a lot of moisture on the decking all along the primary condensate trap and line. Then I saw a pool of water on the top of the furnace housing. Looking further there was water in the secondary/emergency drain pan. Then I noticed moisture at the supply plenum. There was moisture on the top at some of the duct connections (they were pretty well installed with mastic) and some moisture on the decking under the plenum. As I bent down to look closer under the plenum I noticed that the bottom panel of the plenum was bowed out.

I touched it and my finger went straight through and a stream of water flowed out. The material was completely saturated. I brought the homeowner up to the attic and explained the moisture problems to him and put a bucket under the plenum. I asked if they always kept the thermostat set at 65. The answer was yes. I would love some input on this problem/situation. I told him that due to the low temperature they are maintaining, they are creating excessive condensation, as well as apparently creating condensation inside the plenum and perhaps even the ductwork. That he should have everything checked by a licensed HVAC guy and discuss with him whether there are any modifications they can add or incorporate that will allow them to cool the house that much, without these problems developing. I also suggested that he have a mold sampling done. As it seems that this is a perfect environment and has been present for months. Are there any methods that can be incorporated to remove moisture and allow them to run the system that low?

It seems to me that even if you get the moisture out of the conditioned air, you cant do anything about the 140 degree high humidity air of the attic surrounding all the ductwork and plenum's. I have attached some pictures, but it is hard to see the moisture and problems.refrigerant recovery unit for sale australia Re: Excessive AC Condensation Problemcheap split system air conditioners sale Tom Dietrich For Northampton Countyac window unit extensions Express-Times Endorses Tom Dietrich Remember to vote Nov. 3rd. That is what I thought too. The primary drain was drain fine, you could hear it and I could confirm it with my IR. I din't even ask what their electric bill was. But, as you said the system was just so cold, that everything around the evaporator, located up in the hot, humid attic was condensing out water.

They are going to get it checked out. I told them, and think they understand, that I believe it was more of a usage outside of normal parameters problem than a installation problem. I willcheck back with them later and see what the HVAC guy says. BB code is On [IMG] code is On Plumbing problem at home. Light Bulbs- All Ya Wanna Know Condensation Line Drainage Problem Frost, Ice, & Condensation @ RIM JOISTHere’s a common question we get during Florida summers, “Why is my AC leaking water inside my home?There are multiple causes of this problem. Here’s a common question we get during Florida summers, “Why is my AC leaking water inside my home? But first, turn your AC’s thermostat to “Off” to prevent further damage to your home.To understand why this is happening, you need to know how water forms on your AC in the first place. Your AC’s inside unit contains the evaporator coil (pictured on the right) that cools the warm air blown over it.

This causes condensation (moisture) to form on the coil, just like how water droplets form on a cold glass of water on a hot day.The moisture on the coil drips into a drain pan and down a condensate drain line (a white PVC pipe) that leads out your home.So, with all that in mind, here are a few things that cause that water to leak into your home. A clogged condensate drain line is the most common cause of water leaking from your AC into your home.If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home. In that case, you’ll need to unclog it. There are multiple unclogging methods, like using a wet/dry vac on the condensate line.But the surefire way is to have a professional use a special vacuum to suck the blockage material out. Got an old air conditioner (12-15 years)? The drain pan may be damaged or rusted through, so water just falls right through. You’ll need to replace the pan. Is your furnace and indoor AC unit installed in the basement?

If so then there is a condensate pump that pumps the water outside. But if the pump breaks, the water isn’t being pumped outside anymore. You will need to repair or replace the pump. A dirty air filter blocks airflow over the evaporator coil. When that happens, the evaporator coil gets too cold and freezes over. When it melts, it drips an excess amount of water that the pan may not be able to handle.Check your air filter to see if it’s dirty and change it if needed. You should be changing it every 1-3 months (depending on the season). Similar to a dirty air filter, low refrigerant will lower pressure in the AC system, causing the evaporator coil to freeze over. When the coil melts, water overflows the drain pan.You’ll notice you’re low on refrigerant when:Depending on the severity of the refrigerant leak you’ll either repair the leak or replace the whole AC unit.If you need a new one, read our article, “My Air Conditioner is Dying, and I Need a New One…If changing the air filter did not help, contact Cool Today to repair your air conditioner.
