What affects the price
The final bill for your air duct service depends on a few straightforward factors. We look at the total square footage of your home, the number of vents and return registers you have, and the specific layout of your HVAC system. If you have multiple furnace units or an especially complex ductwork configuration, that adds to the labor time. We also consider the level of buildup inside the system, as systems that haven't been cleaned in many years often require extra attention to get debris-free. We keep things simple and honest. Exact pricing confirmed free on the call.
