When i turn on the central air condition, it starts making loud beeping noise that sounds like door buzzer every couple minutes! the noises go away once i turn off the ac. does anyone know what the problem is? thanks!!
It means it has a fault. try resetting unit by switching circuit breaker off and on it might go away

It's supposed to do that. There should be a drain line on it to direct the water to drain. That line may be plugged up, you'll have to check it out.

SOURCE: My central heating and air-conditioning unit completely stopped working - the model# is e2eb-015hb
manually bump the contactor whare the main power comes in with a insulated object isf unit starts then check for call from stat on stat wire from common to red 24v ac transformer good or see if indoor fan comes on next check call from stat common to yellow 24 v then look for low psi switch to see if it has it locked out could be low on gas

With the phase out of R22, it is suggested to replace the system with a more energy efficent R410A system.

Most heat pumps have an auxillary heat. Many are electric auxillary heat with a heat strip in the air handler. A common malfunction is for the electric auxillary heat to operate when the heat pump is set on cool. To confirm this, locate the conductor that runs from the heat sequencer to the connection on the heat strip. You will see this on the top section of the air handler. Use the clamp on part of the amp meter over that wire. If the thermostat is set on cool and the heat strip is drawing amps, it means the heat is coming on while the heat pump is set on cool. There is usually one or two causes for this, either the sequencer is bad or there is low voltage wires usually behind the thermostat or in the air handler closet that are touching that shouldn't be touching.
If this is not the case, if its not a problem of where the heat is coming on with the air conditioner, it could be a case of the reversing valve malfunctioning. The way a heat pump works is it reverses the flow of the refridgerant. For instance, many heat pumps the reversing valve is activated in cool. That would mean that there is a low voltage circuit that activates the reversing valve when the heat pump is in cool. I'm not sure what model/brand your heat pump is, Goodman and Janitrol for instance, the heat pump reversing valve is activated in cool. In any case, if the reversing valve is not operating properly, when the air conditioning is set to cool it will actually be heating. Or you could set it to heat and it may actually be cooling instead of heating. Please check these two items first and if you have any further questions, please let me know. Especially if you know of any additional problems like the evaporater is icing up or if the air handler fan is not operating when it should.

Several types out there. 99% of them use the same basic wiring.
Red is power from transformer to t'stat. Sometime there is a wire for common from transformer to t'stat too, but not always.
While is for heat. Green is for fan. Yellow is for cooling.
These 4 to 5 wires go on the terminals that are maked with letters: C=common, RH/RC is for power, W=heat, Y=cooling, G=fan.
In most cases, 2 wires from the indoor unit will go to the outdoor unit to power it for cooling. Usually connected to the yellow wired, Y terminal and common or grounded to the unit if the transformer is done in the same fashion.
If you have a heat pump, totally different animal and different wiring too.
Hope this helps you. Good Luck.

is this noise indoor or outdoor, and like a BEEP BEEP or just a similiar sound?
