Air con is freezing/not blowing hard. Water around inside unit. What gives?

Question

The blower fan is working. I changed filter/cleaned outside condenser fins. This helped for 2 days. It is difficult to get to the A Coil to clean, but will look if you guys think this is the problem.

Answer 1

Sounds like you have 2 issues, the first is that the A-coil should be cleaned, should be an access panel that it slides into the ductwork.  The other is that the condensate drain appears to be plugged/dirty, this will need to be cleaned/unclogged as well.  Best of Luck.  Turn the Power Off first!!!

Answer 2

Run the fan ONLY for 30 minutes to clear the ice.Then restart it as normal.It will start cooling again.Could be a backed up drain,dirty coil,or a low refrigerant charge.Check the coil with a flashlight and a mirror.Check the drian by sticking your finger in the pan to check for water or blow the drain out first.

It will keep freezing up till you correct the problem.You'll have to call for servive to check your refrigerant charge.Good luck.

Answer 3

Sounds like your inside coil is freeezing up.  This can be due to not enough air flow or low refrigerant charge.  You need to turn your ac unit off because the freezing could damage your evaporator coil causing a leak in the refrigerant system.  If that happens, you will need a new evaporator coil.

Shut it off and let it defrost overnight.  The easiest thing is to add freon and if it does not freeze up again, problem solved.  

If it does freeze up again then it is an airflow problem.  Clean the evaporator coils and the fins on the blower.  It could also be the bearings on the blower or the blower motor is not spinning at the right rpm.  Sometimes you can set a higher fan speed for the blower motor.

8 out of 10 times it is low refrgerant

Answer 4

First turn power off to unit, get flashlight -take front cover off where a-coil is. I think your a coil is probably freezing up. When you are low on freon the coil will freeze up- this also blocks air flow as ice won't let air flow around coil.

When your ac kicks off - then the ice melts on the coil and drops into pan, sometimes ice chunks block the drain pan outlet and water backs up.

If that's not it - then I suspect your a-coil has dirt in it.

I would call a hvac tech to clean it right-would also be a good time to check unit for proper amount of freon.

You can purchase coil cleaner if you want to try it yourself, it's like the stuff touchless car washes use - it eats away at the dirt and debris. Hook a suction hose from a shop vac up to the drain pan outlet after you remove the pipin from it, Put some coil cleaner in a hand pump sprayer- shut power off and go to work. Rinse with clean water. Have some old towels handy in case you need to sop up some water that spills out.

Answer 5

If it is actually freezing the A coil, it is lack of air flow or low refrigerant charge.  Clean the A coil, cut open the duct and clean it.  Also, check the return and supply air vents are somehow not plugged, you need 400 cfm across the coil face, per ton of cooling so it does not freeze, are the fan blades clean?.   Is it a belt slipping if it is an older unit?  If all else fails, you will need a mechanic, not cheap these days.  You know, Canadian Tire now sells a refrigerant replacement in a can.  Are you in Canada?  It is some kind of propane based refrigerant.  Charge and soap test the joints for a leak, maybe you will get lucky.  Did somebody turn the thermostat right down to the bottom (don't do that) just leave it at say  23 C.
