Ice built up on AC hoses
This happened first 2 weeks ago. I did the search online and followed the instructions to turn off the AC unit, turn the AC fan on until all ice melted, and made sure the air filter is clean. Also, I opened up all air vents in the house where I originally closed off those in the basement and half on the main floor as I thought that can help forcing the cold air up to the second floor. But I guess that's one of the reasons causing the frozen hoses.
Anyway, it has been running ok until yesterday again. A bit of ice built up again, but definitely not as serious as what happened two weeks, maybe 1/5 of ice. I turned off the AC and ran on fan again. Then, turned on the AC in the afternoon after all ice melted. However, a bit of ice built up again this morning. I wonder this is normal during the extreme heat days this week and the AC unit is running hard all day as I am working from home ? or there is something wrong with my decade old AC unit ?
Thanks for any advice.
