cleaning mold and replacing HVAC stuff

[Guest guest]

Hi group.

I am new, and have been reading for a few weeks.

I discovered mold in my HVAC system 8 weeks ago, and am finally getting a full

replacement of my downstairs HVAC system. The cost of getting it cleaned is not

a whole lot less that replacement and upgrade with the 2009 tax credit. I can't

really move out temporarily, as I live in an area with a LOT of moldy

rentals--confirmed by a friend who has already tried to find a place to live in

mold-free. She can't find one at all. I do have filter fans going 24/7, spray

my own four thieves blend (modified), and have had the system off a LOT, with

windows open as much as I can. I had a book from Amazon, loaned it to a friend

who lost my book.

My plan is this:

1. Replace downstairs air handler, ductwork -- all components, basics. They

are infiltrated from one end of the other with saw dust, mold, and moisture.

1.5 All registers and air returns will be taped off with plastic before

tear-out begins.

2. During tear out, I will be suited and masked with negative air pressure and

filter-fans going constantly. I plan to clean the hole for the registers with a

mixture of boric acid and hydrogen peroxide instead of bleach, as the boric acid

will persist and will kill any remaining mold longer than bleach will. I will

have an exhaust fan with me for each area I am working. I will take probably

four double doses of CSM throughout that day.

3. I will also inspect the underside of my house - well-ventilated crawlspace

while suited to check for water-damaged/moldy areas near the register holes. I

will also pull back carpeting from above to check for mold spread.

3.5 New filters in returns (MERV-11) after new system is in.

4. During replacement (or maybe after) I will ozone the house (pets and people

absent for appropriate during and after times) to help clean the remaining air.

I will probably do this every week for a month, keep the filter-fans going, THEN

about one month out from HVAC system replacement, I will do a repeat air sample

test (third party) to confirm reduction of spores.

I have a new HEPA filter in my vacuum, just put a new one in the car's cabin

filtration, and will also ozone the car and the garage.

I might be leaving out some things.

______________________________

Do you see any gaps in the plan for those of you who do this kind of thing? Are

there any big obvious things I am missing?

Do I need to ozone existing exhaust fans (bathroom, kitchen, etc) for good

measure?

Does ozone affect appearance of a finished wood floor?

Thanks,
