You are low on refrigerant(R-22 Freon) in some cases and the evaporator coil needs cleaning

Could be a couple things. Either your filter is to dirty to allow enough air across the evaporator coil, the evaporator coil is dirty, or your low on freon. When you start it up check and see if the larger of the two interconnecting tubing from the inside to the outside is cold or just ambient temp. if its cold you most likley have an air resrtiction, if its not cold then its most likely low on charge.

Why does my home A/C unit result in a constant stream of water coming out of the overflow drain? I've had the same unit for 5 years, and it seems that it drains water in ever-increasing amounts. Als

Sounds like it is freezing up. Kind of hard to say since you did not say whether it is a central heat and air system. My overflow was constantly draining onto my patio from overflow. I crawled up in the attic and followed the pvc pipe where it came in from the outside and closer to the central unit in the attic I drilled a hole in the 90 degree elbow of the pvc and unclogged the pipe which was frozen from running so long. Then I covered the hole with silicone. no more leak coming from overflow

I have a goodman capf 181A5BA unit which is suppose to be heat and central air but the central is not working how do I turn on the central air part of the unit there is a yellow turn switch on the side of...

Did you switch the thermostat to the cooling mode, and turn the temp setting down?
The yellow turn switch? must be a aftermarket addition.
The power must be turned on the the furnace or air handler and also to the outdoor unit, check breakers, and also the disconnect box, it should be located on the wall near the outdoor section of your A/C.
If this helps, please rate the new guy :)
Check the above and drop me a line if you have any more questions.

Pipes frozen on outside of unit, inside unit does not work

sounds like the compressor relay is stuck in the 'on' position .... hence the compressor will not turn off .... to fix it you will need to turn off the main power (unplug) and take off the front panel then look at the circuit board normally the largest relay on the board is the compressor relay ... sometimes you can snap off the cover or break it off at times and clean the contacts ,give it a little spray with some contact cleaner or lub like wd 40 and that should be it .... alternative to this is just changing the circuit board all together ....

The bigger of the two pipes of my central air unit is frozen and i am getting very little cold air please help

Sounds like you have either a low refrigerant situation or an airflow problem. The lack of cold air is most likely due to a frozen up evaporator coil. You should check your filters and call your service man.

RE: Carrier Unit Central

Try first cutting system power for a couple of minutes, even from main. With some luck it can be enough to reset the system, as it looks like a problem with the control board. The control board has also a coin battery and a reset bridge on it , but to access them you need to take apart control unit. Try fist turning off main power switch for 5 minutes or so.

Central air conditioning system

Check the filter(s). Dirty filters is the primary cause for such failures. Secondly check the thermostat and make sure that it is not turned way too low. Anything above 70 is safe from causing freezing on the unit. If the unit is already frozen then turn the unit off until it is totally thawed and then retry.
