I got screwed over by my local air conditioning business. We are currently in a big battle that might result in a lawsuit. The issue started that I wanted to get a new central air conditioning system. I hired the AC company and stressed that I wanted an overflow kill switch with this cooling unit. What this part does is stop the AC from running if there is a clog or excessive leaking inside of the system. The reason I wanted this is because my last cooling system leaked a bunch and I was constantly fighting mold. The air cooling technician assured me he would give me the part on the new AC system. The air conditioner was installed and went to work. Not even three weeks later I had a major leak in the house. Water was all over the place and mold was forming everywhere in my house. The AC unit was covered in mold, the floor and even the walls. There also was mold forming within my walls as well. The house was basically ruined after three weeks of cooling use. I called a different HVAC company to take a look at my system. The guy told me that there was no overflow switch installed so that is why the water leaked. I have called the other company to complain since they have caused thousands of dollars in damage. They have yet to respond to my calls. This is why I am thinking of taking legal action against them. They need to take responsibility for what they did.
