Can this actually happen?
I had a guy come in and clean my furance ducts since I moved in to this home in May and it is almost time to turn on the heat. The previous owners had a dog and we are not animal people so we thought it would be a good idea.
I had a coupon for all ducts cleaned and dryer vent for $55. I expected them to upsell me, which they did as soon as they walked in the door and I declined. When they were done cleaning he told me he saw mildew growing on the blades inside my furnace (which is in the attic). Of course that is a concern since I have a 4 year old. At that time I was not sure if he was upselling me or if it was the truth as he seemed like a "used car sales man". Anyway I told him I would have to look around and talk to my husband. He was pushing me to purchas this $700 service. I called a furance company (in secret) I have dealt with in the past as I had some trust in them and they said they have never heard of that before. They suggested I ask the guy to show me the mildew. I asked they guy to show me and he was shocked, I think he did not expect a girl to go in the attic. He then corrected himself and said the mildew was hard to see but he'd show me and there was a few small specs of white spots. He took his time and I actually couldnt get in the attic because he ladder was too short and was not strong enough to lift myself up.
So to make a long story short, is this normal? should I be worried? I did call a few other people and they said they ever heard of it, but of course for a small fee they could all look for me!
