Home Ac Unit Leaking Water – Much attention is paid to maintaining a properly functioning air conditioning system. Small problems like HVAC leaks are easy to overlook and can cause a lot of trouble if left unattended. Understanding how your system works is a big help in making sure that small leaks don’t become bigger problems.
Most standard heating, ventilation and cooling (HVAC) systems are fluid heat exchangers. The refrigerant is compressed by a compressor and then condensed in a series of spiral tubes called a condenser, releasing the absorbed heat into the atmosphere outside the building. The fan blows on the condenser, so the blast from the outdoor HVAC unit is usually hot. Once liquefied, the gas evaporates in another set of tubes inside the building, called an evaporator. As it does this, the compressed gas expands and cools the surrounding air. The fan blowing over the evaporator is what gives you the source of fresh air you feel coming out of the HVAC duct. After the evaporator, the gas is dried by a receiver/dehumidifier and passes through the compressor to start the cycle again.

As you can see, the proper operation of an HVAC system is highly dependent on the availability of refrigerant. There must be enough of it and it must remain in the system at all times. Therefore, the HVAC system is called a closed loop – the fluid circulates in it without escaping. However, no machine is ever absolutely perfect, so there are many places where this refrigerant can leak.
Why Is My Air Conditioner Leaking Water?
Since the refrigerant flows as a gas, it is extremely difficult to detect a leak, but there are a few things you can look for:
Refrigerant isn’t the only thing you may notice leaking from your HVAC system. A small amount of oil grease/bearings from the fans is normal, but any large oil leak could indicate a faulty compressor and it would be wise to call in an expert. Determining the exact location of any leak is no easy task, so if you suspect one, it’s best to give our friendly Art Plumbing AC and Electric team a call.
All HVAC systems require an annual maintenance check, and if you haven’t been serviced in a while and suspect it may be leaking, it’s better to call in an expert sooner rather than later. Allowing a leaky system to operate can damage the compressor and fan, resulting in an expensive repair bill (not to mention additional utility bills).
The last common HVAC leak is water. As the gas evaporates, it cools the surrounding air above the dew point and thus condensation occurs. This water usually enters a sump under the evaporator and flows by gravity to the outside of the building through a pipe. So if a pipe is dripping next to the outdoor unit, it is perfectly normal. However, if water suddenly starts leaking from the indoor unit or ducts, there is a problem with the system and it is better to check it – unventilated water causes corrosion.

You see, your AC’s job is to draw heat and moisture out of the air in your home. To do this, the system draws warm air through an internal vent (called the return grille) and passes it through the cold evaporator coil of the unit to cool the air.

In this case, moisture forms on the evaporator coil. Like the condensation that forms on a glass of ice-cold water on a hot summer day.
Typically, the condensate on the coil drains into a drain pan and through a condensate drain pipe that drains it out of the house (or into the plumbing system).
Now that you know why condensation occurs and what parts are involved, here are some common problems that can cause a water leak in your home.
If the drain line is clogged – often by dirt, algae, insects or a dirty evaporator coil – water drainage is restricted; which results in a build-up of water that has nowhere to go outside the house.

And because it’s so hot and humid, the air conditioning comes on more often, so it doesn’t take long for large amounts of water to accumulate.
In addition, the drain pan can rust, allowing water to enter the pan and cause catastrophic leaks and dangerous electrical problems in your home. So you will definitely have to replace the boiler.
If your air conditioner is fairly new, the problem could be with how the condensation trap was installed in the system. A poorly designed condensate trap can block drains and cause the drain pan to overflow with water.
What to do: You will need a professional who knows what to look for in a condensate trap design and whether it needs to be reinstalled.

The condensate on the cold evaporator coil may also freeze. If so, there is an obvious problem with the air conditioning. It may even freeze along the entire length of the refrigerant lines in the outdoor unit.
And when it melts, there can be a lot of excess water in unwanted places throughout your home.
There are many problems that cause air conditioning to leak water, but these are some of the most common. We understand that things can get very complicated.
Note: Depending on the location of the indoor unit and the specific cause of water leakage into the house, the damage can be very serious and very dangerous. Many, if not all, of these problems require a specialist to ensure safety and correct resolution. Finding water anywhere in your home is a major cause for concern. In addition to worrying about where the leak is coming from (and how much it will cost to fix!), you are also concerned about damage to your home. The moment air systems force you to leak water indoors, you need to act quickly to avoid water damage as well as costly repair bills.
Why Your Air Conditioner Is Leaking Water?
Thus, closing the air conditioner is necessary to stop the flow of water and prevent any other damage.
Dry any spilled water to avoid damaging the floor, walls, roof, and the rest of your home. Use a shop vacuum cleaner if there is a lot of water.
Drain pipe problems are the most common cause of water leakage from an indoor air conditioning system.
As you may know, a forced air system cools itself by introducing water vapor into the air, which collects in the water (known as “condensation”). When the foundation is working properly, condensate collects on the evaporator loop and flows down the drain line.
Air Conditioner Leaking Water? Here’s What You Should Do
Whenever low-cost installers can mess up a duct line, take that as a tip not to try it yourself. Have the repair done by certified experts who have been trained to prevent future water leaks.
If you help, you can probably replace the rusty pan. You will have to bring in experts to replace the pump.
This is a cause for concern if the unit is operated for too long in this condition, which may result in a blown blower which is expensive to repair. In addition, it may be necessary to replace the entire device.
Are you neglecting regular air conditioning maintenance? In case they haven’t been serviced and cleaned for a while, the AC coils are likely to get a lot of deposits and dirt. Or, on the other hand, the protection outside the loops may be broken or corrupted. In either case, the condenser will probably not continue to flow down the duct coils as it should. Instead, it gets redirected through security gaps and garbage collected, and dribbles in a loop instead of running in the condenser line.
