The song "knock three times , on the ceiling if you need meeeee! This sounds like a slow drain or plugged drain line, just reverse the water flow with a water hose or preassure! (last if its an old system over 20 yrs old you could have a rusted drain pan. try introducing bleach into the system (clorox)!............Thank-you very much!

Put new batteries in the thermostat. Make sure that the switch that power the furnace is in the "on" position. Sometimes people mistake that switch for a light switch and turn it off.

Our central AC has severe leaking ( condensation)...what to do ?


Every airconditioner will create condensation that needs to drain. Your condensation is not going where it is supposed to, probably because the drain is plugged. Find the cooling coils (they might be in the basement, but are probably in the attic) they will be right next to the fan. There will be a pan or tray under the coils and there will be some kind of small diameter pipe or hose that should go to a sewer inlet, or might possibly go outside. You might possibly have a small collecting tank with a pump that will be operated by a float switch. Lots of possiblities, but it is likely going to be obvious once you find the drain hose.
Good luck.

I have a Ruud Model UBHC-17J11NFD in my basement. Water is coming from the bottom of unit and pooling onto the basement floor. What should I check first?


Hello, most likely you have a clogged condensate line, in order to clean it you will need a wet/ dry vac and attach it to the outlet of the line and the suction pressure should dislodge the clog. Also, if the unit uses a condensate pump make sure it is working, if its not it can cause water to pour out onto the floor.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


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.

WATER LEAKING


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.

Water is leaking inside the house


The drain that should be carrying the condensate water outside is stopped up. Compressed air works well to clear the drain.

Leaking central a/c unit


All central A/C units have a condensate drain line that comes from just under the evaporator in the Main air supply plenum.

You may have a blockage in that drain line and will have to remove the pipe to clear the obstruction. Try flushing the drain pipe with warm water until it flows easily from the top to the end.

You might have a gravity drain that goes into a floor drain or a french drain along the basement walls. The other typical drain installation is a condensate pump that the water drains into and when the float in the tank is lifted, a small pump turns on and pumps the water (condensate) out of the house either thru a drain hose thru the wall, or into a drain in the basement, etc.

Check the entire drain line and anything connected to it for any possible obstructions and/or blockage.

If you have any other questions once you take a look at your installation, just add a comment and I'll check back within a day to provide more info, based on your input.

I hope you found this very helpful and best regards!

My indoor unit airconditioner located in my basement


Hi, all a/c's produce water as condensation. Portables have a hose connector near the base. Wall mounted have a permanent hose that allows water to vent out. This pipe can get blocked by dust and fluff usually at the elbow joint. Try useing a small drain cleaning wire or extract all the water out ( i use a big syringe ) and put half a cup full of kettle boiled water in, or a drain cleaner. be sure to flush out well. Good luck. steve, UK

 during Cooling and Dry modes, if the unit is used under conditions of
lower temperature (18C)  the heat-exchanger may freeze, leading to water leakage and other damage.
If the unit is used for long periods under high-humidity conditions, condensation may form on the surface of the indoor
unit, and drip onto the floor or other objects underneath. (About 80% or more)



Increase Temp to 20 and also run coil dry cycle,
