A Richardson homeowner was wiping down the same shelves every couple of days and still losing the fight. Every time the AC kicked on, a thin film of dust settled back over the furniture, and the family’s spring allergies felt worse inside the house than out in the yard.They called Lara’s Air Duct Cleaning. We were out the same day.
What We Found
The home was built in the 1980s and the ducts had never been professionally cleaned. The ductwork itself was fine, no damage and no mold, but years of fine dust, pet dander, and North Texas pollen had packed into the supply runs and the register boots. The supply side is the half of the system that pushes conditioned air back out into your rooms.
When the supply side is loaded like that, every cycle carries a little of the buildup out through the vents and into the living space. You dust, it comes back. Allergies spike the moment the system runs. And because the blower is fighting a restricted path, the system runs longer than it should and the electric bill drifts up, all from something you can’t see until a vent comes off.
How We Cleaned It

We don’t guess our way through a system. We inspect first, then set up to trap every particle before a single vent comes off.
Camera inspection first. We ran a borescope through the supply and return runs so the homeowner could see exactly what we saw: heavy dust on the supply walls and inside the register boots, no mold, no damage. The camera sets the scope of work, not a sales pitch.
Negative air vacuum. We connected our high-powered vacuum to put the whole duct system under negative pressure. Once debris breaks loose, it gets pulled toward collection instead of drifting back into the home.
Compressed air whip. Our air whips agitate the dust packed along the supply walls and inside the boots, the buildup of a vacuum alone slides right past. Loosen and capture at the same time, in the right order.
Whole system, supply and return. The return side feeds whatever it pulls straight back into the supply, so we cleaned the full path instead of stopping at the room vents. Cleaning one side and skipping the other is how “cleaned” ducts end up dirty again in a matter of months.
Registers and grilles are detailed. We pulled, washed, and reset every supply register and return grille, so the parts you actually see and touch matched the work happening inside the walls.
The Result

After the whole-system cleaning at this Richardson, TX home:
- Airflow at the supply vents picked up noticeably as soon as the system ran
- Dust and pet dander fully cleared from the supply runs and register boots
- No dust pushed out into the living space during the cleaning
- The homeowner reported far less resettling dust and easier breathing inside the first week
Why This Matters for Your Home
Supply-side buildup is easy to miss because the symptoms look like ordinary housekeeping: more dusting, worse allergies, a system that never quite keeps up. The cause sits inside the duct walls the whole time.
Richardson makes it worse than most people expect. A lot of the housing stock here is older, with aging duct connections that hold more dust, and the city sits right under North Texas’s cedar and ragweed load on top of steady construction dust and long, dry summers that keep the AC running for months.
The AAFA’s 2023 Allergy Capitals report ranked Dallas #2 in the country that year, which is a big part of why so many homes around the Telecom Corridor and the rest of Richardson feel worse indoors when pollen peaks.
If you want proof before you spend a dollar, the smartest first step is a camera-based Richardson air duct inspection, so you know what’s actually in the system. From there, residential air duct cleaning handles the duct interiors, and Richardson HVAC cleaning covers the blower and coil side when the buildup reaches the equipment. NADCA recommends cleaning every 3 to 5 years, sooner with pets, allergies, or recent renovation work. If you’re dusting more than you used to, your allergies kick in the second the system turns on, or you can’t remember the last time the ducts were touched, it’s time.
