Have you ever been in a house and wanted to turn around and head out the door? Poor indoor air quality can cause you to feel quite uncomfortable in the house. At times, it’s because the air conditioner isn’t turned on during a hot summer day. But, other times it’s the air conditioning that’s the reason your house smells so bad. In such a situation, you have to get to the bottom of this before the system makes your house unlivable. That was the situation I found myself in last summer. I was coming home from work and was greeted by the most unpleasant smell when I opened my front door. I had to step back outside to make sure I hadn’t stepped into the wrong house. It smelled like something had died in the house and was rotting. Or perhaps a skunk had found its way inside and sprayed it’s nasty scent in every room. But, it soon hit me that the air conditioner was the source of the awful smell. I went ahead and turned it off then opened as many windows as possible to let out the bad smell. Since I knew nothing about fixing air conditioners, I had to phoned the area HVAC business for assistance. I spoke to an HVAC technician and explained to him the smell in my house. He came by an hour later after asking me if I had turned off the air conditioner. It turns out there was an actual dead animal in my ductwork that has started rotting. I was quite puzzled about how it got up there. The HVAC expert explained there was a gap in the ductwork big enough for it to squeeze through.
