Mold and mildew growing in air vents

My mom and dad have a weird aroma coming from the air vents in their house.

Apparently, this has been going on for a while without me knowing about it.

My mom finally called me the other afternoon and she started complaining that their whole home just smells like hot garbage or something, however I asked her all the normal questions about it, like whether or not they had a dead rodent stuck in a ventilation duct or something, although she said no. She did say that every time they turned the control unit up or down, they noticed the terrible smell. She said that it didn’t matter whether it was the heating or the air conditioning system, either. She and my dad had tried running both the heater and their central air conditioning unit and the aroma remained the same. I really had no idea what the cause could be, and so I finally told her that she should just call her local heating and cooling business to see what they could tell her. Apparently, the HVAC business that she spoke to said that occasionally your ventilation ducts can get mold and mildew growing inside of them. Whenever this is the case, there can be some really bad smells that come from the air vents when the HVAC systems are running, then the heating and cooling business suggested that this was what was happening at my parents’ house. She made an appointment for them to come do a complete professional air duct cleaning on her heating and cooling system. Hopefully, that will clear up the issue and their air quality will be back to normal soon.
