Duct cleaning...new home...geothermal?
We have lived in our home for one year.
My 2 yr old's allergies flare when the furnace is on...not so much with air conditioning but heating.
When I vacuum by air vents, it's often dirtier compared to other areas...
My builder said it wasn't necessary as they keep covers on the registers during the building process...but I have to wonder!
Any thoughts? Our home is quite large and I don't want to waste the money if it isn't necessary...
