Air Duct Cleaning FAQ — Independence, MO

Is there a real schedule for duct cleaning, or is three to five years just a number people repeat?

Three to five years is a reasonable default for most Independence homes, but the house decides, not the calendar. A 1960s ranch with a full basement, sheet metal trunk-and-branch duct, two shedding dogs and a finished downstairs fills up faster than a 2003 subdivision home with flex duct in a vented attic and nobody home all day. Remodeling moves it up fast, because drywall dust and sawdust end up in the returns and stay there. If you pull a register cover and see fuzz standing up on the duct wall, you are past due regardless of when we last came.

What does the crew actually do once they are inside the house?

We start at the furnace or air handler, look at the blower and coil, and count supplies and returns so we know what we are dealing with. Then we cut into the trunk line, hook up negative-air equipment, and seal every register so the suction pulls through the branches instead of leaking out. Rotating brushes and compressed-air whips go down each run to knock material off the duct wall while the vacuum carries it out of the house. Last, we patch the access points, put the register covers back, and run the system so you can see the airflow difference.

Should I plan on losing the whole day?

No. A typical Independence home runs three to five hours door to door. Postwar split-levels sometimes take longer because the original octopus system was retrofitted over the years and there are odd branches tucked behind basement framing that nobody documented. Big 1990s-2000s homes on the south and east edges with two systems and long attic flex runs land at the upper end. We will tell you our estimate of the time when we walk the house, before the equipment comes off the truck.

Why does the number come out different from one house to the next?

Register count is the biggest single driver, because every supply and return is a separate run that has to be whipped and vacuumed. After that it is access: ductwork hanging open in a full basement is quick, while flex buried under blown insulation in a vented attic means crawling and more labor hours. A second system doubles most of the work. Heavy contamination, construction debris, or a return chase that was never sealed properly also adds time, and we look at all of it during the free walkthrough before anything is committed.

Do I need to clear rooms out first, and how dirty does this get?

Leave the furniture alone. We only need a path to each register and roughly three feet of clearance in front of the furnace, and we will slide a chair or an end table ourselves if one is sitting on a floor vent. The vacuum runs under negative pressure with the collection unit outside or vented out, so the dust leaves the house instead of landing on your floors. We put down drop cloths at the equipment and in the walkways, and we wipe the register faces before we reinstall them.

My airflow is bad and the house feels stuffy. Is that the dryer vent or the HVAC?

They are separate systems, and the symptoms tell you which one. If towels take two cycles, the laundry room gets hot and humid, or the dryer cabinet is warm to the touch, that is lint in the dryer duct. If some rooms never cool down in a 95-degree July afternoon, registers blow weak everywhere, or you see dust streaking on the ceiling above a vent, that is the HVAC side. A clogged dryer vent is also a fire issue, so it gets handled on its own terms. We check both while we are there and tell you straight which one is the problem.

What if there is mold in my ductwork?

We stop and show you. Independence summers run dew points at 70 and above for weeks, and a cold supply line crossing a humid basement or an under-insulated attic run will sweat and grow something. Surface growth on sheet metal can be cleaned and treated with an EPA-registered antimicrobial. Growth inside fiberglass duct board or soaked flex liner cannot be cleaned, and that section has to be replaced instead. If the problem is a moisture source rather than the duct itself, we say so, because cleaning it without fixing the humidity just buys you a few months.

Does a new filter come with the job?

We swap in a standard filter at the end so clean duct is not pulling through a loaded one, and that is part of the service. If you run a four or five inch media cabinet on a Carrier, Trane, Lennox, American Standard, Rheem or Goodman system, those are sized specifically and we may ask you to have one on hand. We will also tell you what MERV rating your blower can handle, since a filter that is too restrictive starves the system. During the November through March furnace season and the long cooling window, plan on checking it monthly.

Can somebody come out today?

Often yes. We hold slots on the daily schedule for same-day calls, and if you reach us in the morning there is a good chance we get to you that afternoon. Peak weeks in July and August and the first hard cold snap in November book up faster, so earlier in the day is better. Call and we will tell you honestly what is open rather than boo
