Yer not slow,just your mind is racing with this house concern.
I am the same way.....wanna know-and be my own best choice.Fukd up my gas forced air furnace a couple yrs ago-tech got there,showed what I fukd up-fixed in 5 mins and educated for 229 dollars.........oh well-learned-paid........an education costs something on any level-school,street smarts/ass kicking it all costs something to learn-Lol
Relax,everybody will survive and you will learn to stay away from those systems-I Kiid-Best to ya man !!
