re: AC Frozen in a Block of Ice UPDATE

If the unit is frozen then everything is working. The problem is you have a freon leak. Freon has a pressure temperature relationship. IF you are a little low and the pressure on the downstream side of the expansion valve is below 32 then it is cold enough that water condensation will freeze and form ice. This starts to block the air flow and you will feel like the blower is not blowing as hard. Never heard of over-cooling. What you described isn't over cooling, you are freezing from low freon. Best way to deal with this is turn AC off and run the AC fan only. Eventually it will melt that ice and you will notice air coming out of the registers normally. Kick the AC back on and it should blow cold but will probably re-freeze again in a day or two. At some point the accumulation of leaking freon causes too much pressure drop before expansion valve, and then the unit won't cool. It sounds like you have a small leak and just need to get it fixed.
So this is pretty much the information I got today from the second company. He got here late and there was still ice so he thawed out what he could and will be back in the morning to finish the job. Will know for sure but he said this is the most likely culprit. Will keep y’all posted tomorrow.
I’ve already learned my lesson that I’m not using Keefe’s again. They did none of this and literally just told me my unit was dead. Burkhardts is the company I’m using now FYI.

Are you in the BR area? I know Burkharts services the New Orleans metro area but didn’t know they serviced BR.
