We use this when we paint metal, vinyl, and asbestos.

For $15k, I'd better be doing a full-blown install of a couple of 5 ton units.If it really is that expensive, at the very least get some $11/hr workers to take out the old boilers/radiators/ect. then take them to a metal recycler and sell the metal for scrap.

Any filthy vent that is found points to a room where I'd give this added attention.Leaving windows open might also contribute dust from the outside.Sometimes the return "ductwork" isn't what you might think (it is not really sheet metal within walls, it just uses the space between studs and floor joists with a cover of metal or foil).

(I only tape to glass or metal.

I am interested in precious metals.

As for the HVAC system, to replace a furnace, condenser and coil with a new 2.5 ton unit (probably big enough for a 1200 sf house), I would generally pay $3000-3500.This assumes the ductwork didn't need any repair...

I have a feeling it has the old metal exterior...That park even looks nice and clean, is it?

I financed a steel fabrication business where we produced metal enclosures for the telecommunications industry, thos small metalboxes you see on telephone lines, terminal boxes you might have noticed in neighborhoods that the phone company uses.

I will probably re-side it for aesthetic reasons, as the old metal siding is pretty dingy, but maybe I can get it to clean up.

I've been told there's no universal type of springs and that there's no way to get replacement Mayfair springs anymore for the metal windows, and that I'll have to have all of these perfectly good windows replaced.
