Residential Air Duct Cleaning in Houston & Surrounding Areas
If you are experiencing excess dust, odors, or visible mold on your ceiling registers, Power Vac America can help. We have been performing residential air duct cleaning in Houston and the surrounding area since 1991 — more than 30 years of experience cleaning Houston-area homes.
Power Vac America cleans your air conditioning system and air ducts in full accordance with NADCA standards. You benefit from our decades of residential experience, our NADCA certifications, and our state A/C contractor’s license (TACLA 28012 E).
In the state of Texas, the residential air duct cleaning contractor is required to hold an air conditioning contractor’s license to clean evaporator coils, cut access openings for proper cleaning of plenums, and to use any anti-microbial products.
When Do You Need Residential Air Duct Cleaning?
Excess Dust?
Over time, dirt, debris, dust, and dander build up inside your air conditioning system and ductwork. The EPA has noted that indoor air can be significantly more contaminated than outdoor air. When buildup accumulates in your ducts, it recirculates through your home every time the system runs. Proper air duct cleaning removes that buildup at the source — so your vents are delivering cleaner air, not redistributing what’s already in the system.
Mold or Fungus?
Visible mold or fungus on ceiling registers and vents is a clear sign your air ducts need attention. In Houston’s humid climate, mold and fungus commonly develop in supply plenums and register boxes. Effective air duct cleaning removes the food source — dust, debris, and dander — then treats the system with an anti-microbial fog and anti-fungal coating to discourage future growth. Our technicians can also identify where moisture is entering the system so the source can be addressed.
Odors?
Musty or mildew-like odors coming from your air conditioning system often indicate a buildup of dirt, debris, dust, dander, and mold within the system. These odors can originate anywhere from the pan beneath the air handler to the inner lining of the ductwork itself. Professional air duct cleaning thoroughly removes all contaminants from the entire A/C system, followed by an anti-microbial fog treatment and anti-fungal coating to address current odors and discourage recurrence.
5 Steps to Cleaning Your Air Ducts
In the state of Texas, air duct cleaning contractors are required to hold an air conditioning contractor’s license to clean evaporator coils, cut access openings for proper cleaning of plenums, and to use any anti-microbial products. At Power Vac America, a NADCA-certified Air System Cleaning Specialist (ASCS) will be in charge of your project.
Upon arrival, we conduct a full inspection of the system. This confirms the system can be properly cleaned and allows us to finalize the scope of work before we begin. We document the condition of the system at the start of every job.
The first goal is source removal — getting rid of all dirt, debris, dust, and dander inside your A/C system. We clean every component of the HVAC system to NADCA standards, including the return ductwork, air handler unit, blower, evaporator coils, supply ductwork, and all grilles and registers.
- Clean the Return: Using a portable HEPA-filtered vacuum, we manually clean the return chase and ductwork. Where appropriate, negative suction and a rotary power brush are used. The return grille is also cleaned.
- Clean the Air Handler: We manually clean the air handler unit (typically in the attic), including the return plenum, blower, evaporator coils, and supply plenum.
- Clean the Supply: We establish negative pressure vacuum on each supply air duct run. Each duct is cleaned with a rotary power brush through the supply register opening in each room. The HEPA-filtered collection unit captures debris to prevent it from being released into the home. Supply vents and registers are replaced with new ones where we carry the correct size, or cleaned and replaced otherwise.
To discourage future fungus and bacteria growth, we resurface the internally lined portions of the supply plenum with a Restoration Insulation Encapsulator/Coating. This also helps prevent degradation of the internal fiberglass liner from air erosion. In most cases, after a proper cleaning your ducts will not need to be cleaned again for several years.
Once thoroughly cleaned, we treat the non-porous components of the system with an EPA-registered anti-microbial where necessary. This step must only be performed by a licensed contractor with the credentials to work on air conditioning systems — which Power Vac America holds under TACLA 28012 E.
Upon completion, we report back to you everything that was done — including before and after photos in most cases. We also flag any conditions within the unit that may need repair. While we do not perform mechanical repair work ourselves, we are happy to refer you to an A/C company or relay our findings to your existing A/C contractor.

Frequently Asked Questions
How much does residential air duct cleaning cost in Houston?
Cost varies based on the size of your home, the number of vents, and the condition of the system. Power Vac America provides free estimates — contact us or call 713-645-4611 for pricing specific to your home.
How long does residential air duct cleaning take?
Most residential jobs take between 2 and 4 hours depending on the size of the home and system. Our technicians work efficiently and clean up after themselves before leaving.
How often should I have my air ducts cleaned?
NADCA recommends having your air ducts inspected regularly and cleaned when contamination is present. For most Houston-area homes, a cleaning every 3 to 5 years is typical — though homes with pets, recent construction, water damage, or visible mold may need more frequent service.
Do you clean the evaporator coils?
Yes. Power Vac America holds a Texas A/C contractor’s license (TACLA 28012 E), which is required by state law to clean evaporator coils. Many duct cleaning companies are not licensed to do this — we are.
Will you replace my vents and registers?
We carry a supply of the most common vent and register sizes on our trailer. We replace them with new ones at no extra charge where we have the correct size. Otherwise they are cleaned and replaced.
Do I need to be home during the cleaning?
We recommend someone be present at the start and end of the job for the inspection walkthrough and final report. Our technicians are background checked and drug tested.
