I have been asked to give a estimate on cleaning 14 AC Units. The Units are on the roof of a industrial plant. If you walk inside the unit - there is dust and a oily residue on the walls, ceiling, & floor. The ducts are not included. They want the 14 exterior units cleaned & the 14 smaller units on the interior.
How would I go about bidding something like this?
Anything to watch out for?
Thanks
