Indoor Air Quality Solutions, IAQS

I have a house in Clermont, Florida and I called Indoor Air Quality Solutions, IAQS because I had recently bought a house. It's been a debacle. There's a bad mold smell in the house, and there are mold stains coming through the sheetrock. The new humidifier doesn't work and the two-year-old air conditioning unit is not working properly. The house was power-washed before it was used, but there's still black mold on the walls. I'm very disgusted, as this is a very expensive house, and we've already spent so much to try and resolve this. The dehumidifier works, but when it is, the air conditioner tends to stop after it reaches a certain degree. The problem has not been taken care of, and it feels like there's no resolution in sight. It's been a really bad experience for us.
