I've a mobile tech due in two days, his way is to put it on its side, but thanks to everyone's comments we'll at least do it early in morning so time to let it sit if need be before heat of the day comes on. After two mobile techs did not even return my calls was more motivated to go with the first presumably competent one I could find. Local state park ranger spoke highly of him.
New question I did not think to ask before.... while the ac works as well as last year, a difference this summer is after an hour or so running, the airflow rate is sometimes significantly less---sometimes, not always, like an old soul that occasionally runs out of oomph, that is, just barely maintaining temperature at that point, not cooling down anymore. Shut it off for a couple of hours and then it cools with full airflow force again. My guess is the coils may be clogged/quite dirty, appreciate hearing anyone's thoughts. The more understanding I have the more apt I am to appreciate the tech's know-how level and how thorough they are. Thank you.
