Pardon my ignorance in this post, I'm not very familiar with HVAC and the correct terminology so I've tried to circle some things for clarity in the photos attached.
Two nights ago I noticed that our house had gotten noticeably warmer (we usually keep the thermostat somewhere around 69-70 degrees). I checked the thermostat to realize that the house's temperature was around 5 degrees warmer than the setting, so I went and checked the indoor unit. On quick check, I noticed that there was ice around copper tubes and an insulated pipe that runs into the front of the unit (I've circled where I noticed the ice in 1.jpg attached).
I turned off the unit and let it sit for a few hours then I took out all the filters (I have permanent hydrostatic - I think that's what they are called - filter system in place). When pulling those out, I looked up in the AC into a sloped vent and the entire thing was covered by a sheet of solid ice (see 2.jpg attached).
Perhaps it's worth noting that when running, it does blow air and the air isn't overtly cold but it's not warm either, it's somewhere in the middle temperature wise.
I'm sure I need to call out an HVAC tech to fix it but do you all have any ideas on what's causing the issue, if there are anyways to fix it without an tech call, and if I need a tech any ballpark on the cost to fix such an issue?
Thanks for the help!
