Water keeps leaking from central air condition

The drain pan for the evaporator needs to be checked for cracks & make sure the evaporator is centrally lined up to the pan. Sometimes condensate shield are installed to manage the water blown off the evaporator coil. Generally with the evaporator housing open, check any signs of where water has been traveling ie rust lines or calcium deposit lines to determine were the water is coming from.

How a Central Air Conditioning System Works



Facts:

• The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
• Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
• Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
• The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
• Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:

• Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
• Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
• Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

It is normal for an air conditioner to leak water out the back. This water is actually the humidity being taken out of your house. Being vented out in to the garage is always an issue with condensate water. I have seen some people take a funnel and run a hose outside the garage somewhere. Keep the vent closed. It will be harder to cool the house with the vent open because it lets outside air in to the house.

Water should come out of the back of a wind unit when it is humid out, usually a drain hole. If water is leaking inside from a window unit, check that the outside drail hole is not clogged or maybe it is not tilted downward enough outside (Usually a very slight tilt down toward the outside to help the water drasin out the back outside). Also, if you have excess water forming, you may need to clean the coil. For central air units water should be drippng outside the home via a pipe or tubing and if the drain tube or pipe is clogged with scum that forms inside the pipe water will back up and overflow in the house near the heater/air conditioning unit. Also, some units have a pump to pump the water out and it may not be working.

Sounds like ether you have a plugged condensate drain,or the drain pan is rusted out.If it it clogged you can squire a bit of water through to unclogg.If it is rusted youll have to wait it out.Good luck.

it happens when aircondition is run for cooling and evaporator is frozen of ice. if you turn off aircon ice will defprost from evaporator.

Most thermostats have a setting for the fan called, "manual". That keeps the fan on continuously. The electronic thermostats can fail in a "fan on" condition. That would require a new thermostat. I also saw one air conditioner with a fan relay welded "on" by electrical surge. That would require a new relay.

This could be 2 issues. 1 being a simple issue and the other requiring service.

First issue:

Make sure you have the thermostat on cool and not Fan.


Secondnd issue:

If the thermostat was on cool and not fan, It sounds like the freeon level is low in your system. This will cause the air to not be cold. You will need to contact your local heating and air conditioning shop and have them take a look at this. You may be low on freeon because of a leak in your system also. It is recommended you get your system checked and tuned up every year. The cost of this is usually between $50 and $90. It is a good idea because they can catch problems early on before they become larger problems. It also will also keep your central air system running efficiently and use less power compared to a system that has not been maintained.

Check for an obstructed drain line.
