The last two houses we have rented had mold in their HVAC systems.
The mold was primarily in the ductwork and it was gross.
It also made the whole family sick. We were diligent with keeping on top of the HVAC maintenance and everything but these were super old houses with super old HVAC systems. That is why I was worried when we decided to buy our own home. I thought it might have a moldy HVAC system too and we would have to pay thousands of dollars to repair it. You can’t just pick up and move when you own a home like you can when you rent one. We looked at a bunch of houses before settling on one that we all loved. Each kid will have their own room now. It has a remodeled kitchen and a fireplace. But the best part is that the house does not have a forced air HVAC system. So no ductwork or parts that can get moldy. Instead it has a ductless mini split system. All of the main working components are outside. The inside parts are up on the wall and not in a utility closet. There is no ductwork. It only has small hoses that lead from the outside to the inside. The whole ductless mini split system could be inspected by us daily if we wanted to make sure there is no mold. I really like that. Additionally, we hired someone to come into the house and use a mold detector already and they said the house is clean. I hope we get the house.
