What drives the price of air duct cleaning in the Hill Country, why the "$99 whole house" ad never ends at $99, and how to get a number you can trust before anyone starts.
Search for air duct cleaning near Marble Falls, Georgetown or Lakeway and the first thing you see is a $99 special. The second thing, once the truck is in your driveway, is a bill that looks nothing like it. Here is how duct cleaning is actually priced, what moves the number, and how to make sure the price you hear is the price you pay.
Duct cleaning is labor and equipment time. A proper job means a negative-air machine hooked to the trunk line, every supply and return opened and agitated, the plenum and the blower compartment cleaned, and the registers put back. In a typical Hill Country home that is half a day for a two-person crew, not forty minutes with a shop vacuum.
The coupon price usually covers a handful of vents and nothing behind them. Once the technician is inside, the trunk lines, the returns, the coil and the plenum become add-ons, and the homeowner is negotiating in the hallway. The pattern is common enough that the industry association warns about it. If a price sounds impossible for half a day of two people with a truck full of equipment, it is.
Every job starts with a free inspection with photos. You get a written per-line price on the spot. If the system is clean, we say so and leave, which happens more often than people expect. Most of our customers in Georgetown, Leander, Horseshoe Bay and Marble Falls book the same visit for the dryer vent, because the truck is already there.

They came to do the full inspection of our HVAC system and performed a thorough inspection with photos and a very detailed list of quoted recommendations. Gary and team were punctual the 3 times they came to our home and their price was very reasonable.
