May the result turn out to be worth the process.
At least I’ll be able to use the furnace, and more importantly, the A/C when the hot, humid months arrive. For now, I can live with the space heaters. In the summer, there will be no recourse if I expect to breathe properly, and will have to run the A/C.
One thing is sure...I won’t be giving up the ozone machine any time soon.
