Question

Evaporator coil freezing


Ok, I have a Goodman Ck30-1B unit outside and an evaporator coil in the top of the furnace. The system has run fine until recently. It has started freezing the evaporator coil. When the coil freezes it will freeze all the way out to the line on the unit outside, just the line nothing else. I have checked everything I can think of ( filter, return air vents, draining properly). System doesn't seem to be blowing as cool of air or cooling the house as well as it has in the past. Does anyone have any idea what the heck is going on? Is it just that the refrigerant level is low or do I have a bigger issue? Also what kind of refrigerant does the Goodman CK30-1B take? Can you recharge low refrigerant yourself or do you have to have an HVAC tech do it ( I've seen instructions online for doing it yourself)? Quick answers would be greatly appreciated as I would like to be educated so that I do not get ripped off by an AC company telling me things need fixed that don't need fixed. Thanks all!

Evaporator coil freezing


If you are getting enough air over the evaporator then low charge is the next place to look. Need a set of gauges to do that.

Evaporator coil freezing


Look at the bottom side of your coil. If it's dirty there wont be enough air flow and it will freeze up. The other cause is low on refrigerant and you can't even buy it without being EPA certified. Time for a service call if the coil is clean.

BYW if it's low on charge then it has a leak. Could get real expensive fast. A good tech will go though everything and tell you what it needs to run and what it needs to run right.
