    how do you clean a unit that is in a closet? It's the central air and heating unit in the home. It does have the PC pipe attached from unit to drain, my question is do they have an overflow valve in which excess water drains? If so, then that will tell me that the original drain process is not working properly.

Hello Cheryl, what they are talking about is a drain. As air conditioners run they collect moisture from the air on the evap(in cooling mode) or condenser ( in heat mode). This moisture will run off the part and flow into the tray. In the cooling mode, the moisture is slung onto the condenser to help cool it down, thus be more effective. I always recommend once a year remove the unit and clean all the coils and oil the fan motor. Household oil will work for this. During this cleaning find and clean out the drain. If it gets clogged that water can run back into the home. The PC pipe is sometimes attached to the unit to direct the water to a designated place. These units are common in hotels and they use the pipe to keep the water from dripping on the guest as they walk under the windows. Hope this helps.

    Hello Cheryl, Sorry about that, since you didn't state it was an HVAC system I assumed the window style. On your unit all the water does is drain out. There isn't any overflow as the water isn't used for anything. The plastic pipe is your drain system. They become clogged over time. I use 50 psi of compressed air to blow out the drain, then slowly flush it out with hot water from the tap. Depending on how clogged the drain is, you may have to do this several times. There should be a outlet on the outside of your home where the water goes. I have seen this get clogged at the outlet to sometimes with plant material. Hope this helps.

All my other AC Units have had a drain directly to the sewer system...usually connected under a sink. Does my Ruud unit only have the drain to the outside of the house? Usually, when the AC is draining...

If you have a CENTRAL air unit, you should have an overflow to a drain in the furnace area. So I don't understand what you are saying about a connection to the drain under the sink!

Do you have the make and model correctly listed? Because with your question it does not agree what I know about the Ruud Central air that you listed.

My frigidaire air conditioner is spitting water out the side and the drain hole is clear is there a secondary drain hole?

The tray that holds the condensed water from the evaporator
may be clogged, it may be clogged before the cleanout hole,
where the tray joins the pvc, if this is the case you may have to
power down your ac unit, there is a panel on your heater unit
that you will have to access to expose the evaporator coils and
you will see the tray where the condensation builds up and flows
thru a pvc pipe to go outside. also make sure that the pipe going
outside is at a slope so that the condensation can flow and not
clog the pipe. make sure that water can flow from the tray thru
the cleanout hole. once you correct the problem. you need to reseal all the seams with duct tape or metalic tape, you can purchase at most hardware stores, to make sure their are no ac
cool air leaks other than thru your ac vents. good luck!

There is water leaking out from the bottom of my furnace. It leaks whenever the ac is running.

Hello, sounds like a clogged condensate line or a faulty condensate pump if the unit has one. Cleaning the drain line should fix the problem.

Radiator fluid is leaking by firewall when the a/c is on. It isn't condensation. Can't find a hose leaking. Envo has front and rear air. It is when the front air is on.

HMMM thinking out aloud here ,you sure its not condensation running down from the low pressure pipe on the AC ,,,, touch it with your finger and see if tastes sweet if so its antifreeze ,and the only cause of this that i think of is the shut off valve ,so when ac is on the valve closes and its leaking ,when ac is off the valve is open and its not leaking ,stop gap measure for rest of summer is to put two brake pipe clamps on the heater hoses

When the ac unit is on the water comes in the house

The condensate drain line is clogged, causing the condensation water to overflow. You can use a shop vac to clear the line. attatch it to the outlet side of the line. also clean out the condensate drain pan located at the bottom of the indoor coil.

HVAC problem

One thing you can check is the condensation line to see if there are wires going to it. This is the plastic pipe coming out of the indoor unit. If there is a float switch and the condesate line is clogged then it will not allow the a/c to operate. If the line is clogged you can use a WET/DRY vacuum on the end of the pipe which should be next to the outdoor unit. Hope this solves the problem. Good luck. Keep me posted please.
