Service was professional. Techs showed me before and afters of cleaning. Mildew smell is gone inside the house. Two complaints: 1. They did not bother to put the foot stool and ladder they borrowed, back after use. If you ask to use someone else’s equipment, put it back when you’re done – it’s pretty basic. They seemed to be in quite a rush to leave. 2. I was charged a $50+ “disposal fee” to throw out an old air filter upstairs, but they forgot to throw out the downstairs air filter too.
