You work in a trade the scammers ruined. Every homeowner has seen the $49 'whole house special' that turns into a $1,200 upsell, so they search for duct cleaning already suspicious. That's actually your opening: the company that looks transparent, certified, and honestly priced wins by default, because the bar set by the coupon blasters is on the floor.
Modern Websites builds duct and vent cleaning sites around proving legitimacy: real pricing explained plainly, your process shown step by step, certifications displayed, and a dryer vent safety page that sells a service most homeowners don't know they need. Live in 7 days, $250 a month, everything included.
