Well, the boys from "Alright Heating and A/C Inc." were at the house this morning to fix our furnace. After about thirty minutes of wrestling with frozen connections (rust, not ice) they finally removed the "smart valve" and replaced it with a new one.
I found out that anything with the word "smart" in it, means you can translate that to mean "expensive". I mean $302.00 expensive! Add on another $90 and you got yourself a bill!
Well, to be honest, we don't have to pay for it; that is a church parsonage maintenance issue. At least we'll have heat in the house tonight!
Praise the Lord!
