If you only knew that half of it Bob. She completely rebuilt my entire HVAC system. Like from scratch brother. My buddy who is a wholesaler told her the new furnace would be $2200. She went and got the guts somewhere brand new for $700 then modified the box and the trunk to accept it. Then took every duct out of the attic and when the new ducts you can buy these days were too chinzy for her liking she power washed the old ducts with some ridiculous solvent she found, wrapped them all in insulation correctly, bought new vent boots and reinstalled them. She changed the water pump in my van while I was at work. It's a Dodge Caravan. You have to unbolt motor mounts and jack the bastard up to get to the water pump.
She did better than half my roof so I could still go to work.
She cleans up real nice too. ;-)
