Had the crawl space inspected today by a mold specialist. Yes we have mold......... Inspector wants to tear out the insulation between the floor joists, clean up the mold & apply an encapsulant. Will also apply one piece moisture barrier & seal off foundation vents ( now has 4 mil plastic over 80% of the ground generously overlaped....He will also use an air scrubber. He wants to install a Humidex in the crawl space. Says this will improve the air in our house also?? Verification on this please? Waiting for estimate> >>>>>>>> Now what I REALLY need help with is what to do with the existing heat pump.. It is eleven years old BUT we do NOT have the emergency heat unit (furnace?). When it gets in the mid 20's I have to turn the heat pump OFF & turn on the ceiling heat strips.... Here's the problem --------- When I turned the heat off a few weeks ago there was still a very noticable draft coming through all of the vents especially the ones closet to the heat pump & it smelled of MOLD big time. I then wrapped each vent cover in clear wrap & again in reynolds wrap stopping that air from coming into the house..... Even after doing this the specialist smelled mold in the house (so do I).. Specialist wants to clean the ducts & seal the duct work but I am concerned this may not get rid of all the mold. (there is no mold on the coils).. The worse smell is in the room over the main trunk area (before it starts branching off)& I'm thinking that might be where most of the mold is..... I am leaning toward having the heat pump replaced (perhaps even the duct work that may be as old as the house -1975ish?) with a split unit & the furnace part will have to go inside the crawl space (per previous HVAC tec)......... IF I replace the heat pump is there a unit or ? that can be used to do what the Humidex does? Hubby is a teacher so we need to do all this on teachers pay. We want to sell the house 3-4 years down the road...( R U permitted to suggest brands here)?.................... Curious question regarding the existing heat pump. Is it suppose to be drafty like that even when the wind is not blowing? Where is the air coming from that is coming through those vents?............... Added..... I do have a dehumidifier set at 50 % in the crawl space & it is dry. We are near Louisville,KY.
Thanks again for all of your suggestions.
