My mother and father have a strange smell 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 day and she started complaining that their whole house just smells like hot garbage or something, 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, even though she said no! She did say that every time they turned the thermostat up or down, they noticed the awful smell. She said that it didn’t matter whether it was the heating or the cooling system, either. She and my dad had tried running both the electric heater and their central air conditioning unit and the smell remained the same. I really had no idea what the issue could be, so I finally told her that she should just call her local heating and cooling contractor to see what they could tell her. Apparently, the heating and a/c supplier that she spoke to said that periodically your ventilation ducts can get mold and mildew growing inside of them, and whenever this is the case, there can be some really nasty smells that come from the air vents when the heater and a/c system is running. The heating and cooling supplier guessed that this was what was happening at my parents’ house. She scheduled an appointment for them to come do a complete professional air duct cleaning on her heating and air conditioning system. Hopefully, that will clear up the concern and their indoor air quality will be back to normal soon.
