Respected sir/madam,
I had a central air conditioner installed by sears 2 yrs ago. This year it caused over $30k in damage to my house. The condensation drain was improperly installed and the drip pan had tiny holes in it caused by the installer. there also was a 3/4 inch gap between the air handler and bottom of the return vent. The condensation had dripped into my attic and saturated the insullation (like a sponge). It then ran down my walls and between my sub floor and wood floor. This caused major mold issues(over $6k). Once the mold was cleaned it took almost 3 months to get my house back to normal. Had to rip up and replace w/w carpeting, wood floor, sub floor. Also had to remove much of my ceiling and several walls. My insurance covered all except the actual repair of the ac, approx 2k.
