Ice Cold Hospital with The Air Conditioning Blasting

I just ran down to the hospital to take a quick coronavirus test and I suppose they had the control device set to “Snowing”; I am flying in more than five afternoons and if I maintained positive then we would have to get a dentist’s note saying I am okay to fly. Luckily, my test was downside. Now I am home again and I have my central furnace on so I can hot up from that freezing experience. I wonder why they have to keep the hospital so cold? I have no method even though I do have a great method that I am delighted I didn’t become a dentist. I method on cleaning my HVAC method this week as it has been a long time since doing so. I had the flu, not Covid, a few weeks ago and it was 1 of the worst experiences with sickness I’ve felt in a long time. Covid is nothing compared to a terrible flu. I was going to wash my air duct a week ago even though I was still coughing a lot and in no shape to be around dust and bacteria. I guess better now and should be able to wash everything, given that I wear a mask and make sure not to stir up a lot of dust when I am cleaning the vents and ducts. I have a washable HEPA filter so it isn’t a big deal removing the dust from it because I just put it in the dishwasher by itself and it comes out perfectly clean. I l acquired that trick from a YouTube video.
