You can get plenty of strong and quiet cool air or hot air with these fast and cheap.It’s called diy , but you may not be good with carrying hundreds of pounds of cement. Get an electrician or you could kill yourselfI was quoted 25k to do the job but I did for 6. There was some suffering involved. I paid an electrician $1500 so far and $400 in supplies. Nearly done.I have completed most of the learning curve, but I’m almost done.
