I’m considering having the HVAC ductwork inspected and possibly cleaned, but I’ve realized there are quite a few companies offering air duct cleaning Miami services. That makes it difficult to know what separates a thorough professional service from a basic cleaning. What questions should homeowners ask before hiring someone? I’m especially interested in things like whether they inspect the entire duct system, explain what they find, protect the home during cleaning, and clearly describe what equipment they use. If you’ve hired a duct cleaning company in Miami before, what did you wish you had asked beforehand?
