Gas and Oil Home Heating Furnaces - Furnace in flood??

Hi we buy houses for rentals--we close today on a house that was in a flood--back water about 3 years ago--the house has been in foreclosure for 5 yrs so no one removed the furnace or hotwater tank--the basement got about 3.5 ft of water--oh and the ac condensor unit was covered too--it was 3 years ago so dry lol--but we are hoping the furnace can be cleaned and used again--the hot water tank we will replace--what all do we need to do to the furnace--we will have pros but I just do not trust service ppl anymore to do a complete job--I will take my before photos today and make an album and will post it if you want to see it--oh I only paid 27 for the house so no I am not crazy lol even if I have to buy a new furnace--oh 2 other ?'s how do you remove a furnace if it would flood again--well before it would lol--and I have a space upstairs that I could put the HW tank and a furnace--how hard would it be to move a furnace to the next level--I will do this if I have to buy another furnace

If you think that much about flood. Id put a new furnace and the water heater up in the attic and be done with it. Or on the first floor and blow down in the ducts you have now. I did that for one of my sons
Down in Mobile AL.
For the AC condenser Might put it up on a 1' or 2 ft high pad.
If the units sat for 3 years not athing did to them. just get all new.

can't you stop the flooding?

Furnace should be professionally inspected, cleaned, and serviced if it has been in a flood. The following link provides helpful info: http://www.cdc.gov/nasd/docs/d001401-d001500/d001495/d001495.html
