First, turn off your AC to prevent serious water damage and dangerous electrical problems. Next, we highly recommend calling an HVAC company for assistance.
Ac Unit Leaking Water Inside
Your air conditioner’s job is to remove heat and humidity from the air inside your home. To do this, your system draws hot air from an indoor vent (called a return grille) and moves it through your indoor unit’s cold evaporator coil to cool it.
Signs Your Ac Is Leaking Freon
When this happens, moisture builds up in the evaporator coil. Just like condensation on a glass of ice water on a hot summer day.
Normally, the condensate on the coil drips into a drain pan and a condensate drain pipe that takes it outside of your home (or into your plumbing system).
Now that you know why condensation occurs and the relevant parts, here are some common problems that can cause water to leak into your home.
If your drain line is clogged, usually by dirt, algae, insects, or a dirty evaporator coil, the water drain is limited; it causes a buildup of water that has nowhere else to go but your home.
How To Stop Water Leaking From Hvac
And because it’s very hot and humid, your air conditioner runs more often, so it doesn’t take long for large amounts of water to accumulate.
Also, the drain pan can rust, causing water to run out of the pan, causing disastrous leaks and dangerous electrical problems inside your home. Therefore, you will definitely need to replace the pan.
If your AC is fairly new, the problem may be in the way your system’s condensation trap is installed. An improperly designed condensate trap can block the drain and cause the drain pan to overflow with water.
What to do: You will need a professional to find out what to look for in condensate trap design and if it needs replacing.
Why Is My Ac Leaking Indoors?
Condensate on your cold evaporator coil can also freeze. If it does, there is an obvious problem with your AC. It may even freeze in the refrigerant lines to the outdoor unit.
And when it melts, you can have a lot of unwanted water in unwanted places in your home.
There are a number of issues that cause water to leak from your AC, but these are some of the most common. We understand that these things can be quite complex.
Note: Depending on where the indoor unit is and what caused water to leak inside your home, the damage can be quite substantial and extremely dangerous. Most, if not all, of these problems require a professional to ensure safety and proper resolution. Finding water anywhere that does not belong in your home is a major cause for concern. While you’re stressed about where the leak came from (and how much it will cost to fix!), you’re also worried about damaging your home. When your compressed air system leaks water inside, you must act quickly to avoid water damage, which can cost as much as repair bills.
Is Water Leaking From Air Conditioner Dangerous?
In this way, it is very important to turn off the air conditioner to stop the flow of water and prevent further damage.
Wipe up any spilled water to avoid damaging floors, roof walls and the rest of your home. If there is too much water, use a shop vacuum.
Problems with the condensate duct line are the most common cause of an AC system leaking water into the home.
As you know, the way your forced air system cools is by expelling water vapor from the air, and this water collects in it (called “condensation”). At the point where the frame is working as it should, the condensate collects in the evaporator loop and flows down the duct line.
Reasons Your Air Conditioner’s Drain Pan Is Full Of Water
Whenever discount rate setters can ruin a channel line organization, take it as your warning to avoid trying it yourself. Make sure it is repaired by legally trained experts to avoid future water leaks.
If you’re helping, you’re probably replacing a rusty pan. You will need to bring in experts to replace the pump.
This is a cause for concern if your unit continues to run for too long in this state and a fan is seizing up, which is costly to repair. You may also need to replace the entire unit.
Have you neglected your regular air conditioner maintenance? If it hasn’t been maintained and cleaned in a while, your AC curls are probably picking up a lot of debris and dirt. Or, on the other hand, the outer guards of the handles may be broken or damaged. Either way, the condensation probably won’t continue to flow from the curls into the duct line as it should. Instead it is redirected by gaps in the defense and collected garbage and drips from the arm instead of running into the condensation line.
What Is A Condensate Drain Line?
In case you see small drops and puddles instead of too much water, look for obvious droplets falling from the evaporator coil. Last week’s blog post on the review of air conditioners was about conventional air conditioners, which are an evaporator coil sitting above a furnace in a basement. In these systems, condensate leaks can be a mess, but that’s nothing compared to a condensate leak that happens in an attic air conditioner or really anywhere that has a finished space below.
A few weeks ago I came across a leaky unit and found moisture all over the first floor and basement ceilings. The dark blue dots in the image below are wet areas on the basement ceiling and none of them are visible to the naked eye.
I don’t come across many of these units in lofts, so from time to time I have to go back to the state code requirements for these units to make sure the condensate drain system is set up correctly. I was planning to put together an easy-to-use summary of condensation requirements for inspectors at my company, but I decided this would make a good blog topic too, so here they are.
If you want to know every little detail, leaving out some information, read the actual code section. This is the section that deals with the disposal of condensate for areas where damage to the building could occur if condensate leaks. Like in an attic.
Reasons Why Your Ac Unit Is Dripping Water
When this type of installation occurs, there are four options for dealing with condensation. However, they are not listed in this order in the mechanical code; I rearranged the order as I think it makes more sense to read it that way. Choose one of these four:
1. Drain pan with separate drain – A separate drain pan can be placed under the unit and must have its own drain line. This pan should be at least 1-1/2” deep and at least 3” wider in any dimension than the condensing unit.
2. Drain pan with shut-off device – A pan of the same dimensions as listed above can be installed without a secondary drain provided a shut-off device conforming to UL 508 is fitted. I don’t have that standard and neither do I. have this standard. I know what you’re saying but I’ve seen a lot of these shutdown tools and they’re pretty simple. They fit inside the drain pan or are placed on the side of the drain pan. That red device in the picture below. This particular one is called the Concentrator Cup.
If water fills the pan, a float will turn off the air conditioner. This type of device is quite simple and effective and is the most common method used in Minnesota lofts.

3. Shut-off device – a shut-off device for the air conditioner can be installed alone. If this is done, it must be installed on the “primary drain line, overflow drain line, or supplied equipment drain pan”.
4. Separate overflow drain – a separate overflow drain line can be connected to the secondary drain opening on the equipment, but if this is done, it must be drained in a conspicuous place. It cannot simply be evacuated to a floor drain or to the open air. The purpose of this is to alert someone that the water is coming out of a place where it shouldn’t be and there is a problem. Ideally, someone would go check it out and clear the blockage in the blockage that is causing the condensate to leak in an unusual place.
While it’s not common to find air conditioners in lofts in Minnesota, I probably see condensation drain systems installed incorrectly in at least half of them.
