My mom and dad have a odd smell coming from the air vents in their house, apparently, this has been going on for a while without me knowing about it, but my mom finally called me the other day and she started complaining that their whole home 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 he said no, she did say that every time they turned the temperature control up or down, they noticed the awful smell.
She said that it didn’t matter whether it was the heating or the air conditioner, either. She and my dad had tried running both the heater and their central air conditioning unit and the aroma stayed the same. I honestly had no clue what the problem could be, and so I finally told her that she should just call her local heating and cooling company to see what they could tell her. Apparently, the heating and a/c specialist 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 terrible smells that come from the air vents when the heater and a/c unit is running, then the heating and air conditioning specialist seemed to know 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 their HVAC system. Hopefully, that will clear up the problem and their indoor air conditions will be back to normal soon.
