Freeze UP

Just as a general condition of this AC, what are the possible causes for this. We are in Central Fla, its 92F outside.

Dirty filter, fan speed to low, or low on refrigerant.

Tx. We let it melt last evening, changed out the filter, cleaned out the condensate line, seemed to have plenty of air blowing out of the registers afterwards, but this again today. Seems like low on refrigerant then.?

Low on refrigerant or a lot of humid air getting into the return.

Is this the first time you are having this problem ?

That coil looks like it's wedged in the corner of the ductwork and it doesn't look like it's allowing the air to flow properly thru it.

Yes, the first time for a freeze up. Don't know why the front area (towards the inspection cover) is thick with ice on the "fins" and not so much towards the back side. I assume the fan is pulling the air up thru the "A" coil and then on to the duct distribution for the house?? I'll try to get a model/make number. Tx

Grandson just emailed me and said he had a tec out this evening and this is what he said:

"The coil is dirty! Also, we have issues with the duct work..
They used an old style and it breaks down from heat..
This allows air to penetrate the duct work and heat the cool air - the hot air then enters the house. This is why there is a discrepancy with thermostat temperature..
It was also low on gas... Tech said that the line changes sizes multiple times underground from the handler to the condenser. This means it was spliced a few times and is probably leaking!
Should have her running strong by the end of the week!
The coil is going to be cleaned, freon was added, and they are replacing the duct work this week."

Sounds like you guys were dead on!! Tx.

Icing on one side or part of the coil is a classic indication of a low charge.

Multiple problems.... at least you know now what to do to get the cold air back.

Good luck
