Frequently Asked Questions

We clean the entire supply and return network from the plenum to each register, plus the blower compartment, evaporator coil (if accessible without refrigerant disturbance), and filter slot. In San Antonio's limestone-heavy Hill Country environment, we regularly find compacted dust and construction debris in older Terrell Hills and Alamo Heights homes built before modern filtration standards. Our Rotobrush and Nikro equipment agitates and extracts debris from each run, and we photograph the interior before and after for your record.

A standard residential system takes 3-5 hours for a two-person crew. Larger homes in Castle Hills or Windcrest with multiple zones, or systems that have not been serviced in over a decade, run longer. We book a real arrival window, text when the tech is en route, and stay until the documented work is complete. Rushing a duct job means leaving debris behind.

Every 3-5 years for most homes, sooner if you have pets that shed, recent renovation dust, or occupants with allergies or respiratory conditions. San Antonio's combination of Hill Country pollen, caliche dust, and high summer humidity accelerates buildup in return lines. Homes near construction in Live Oak, Converse, or Universal City often need more frequent attention. We inspect and advise based on what we actually find, not a calendar.

Moderately, if your system was significantly obstructed. The Department of Energy estimates that 25-40% of heating and cooling energy is wasted through inefficiency; clean ducts remove one source of resistance and allow designed airflow. The bigger gains usually come from sealing leaks at the plenum and connections, which we inspect and can quote separately. We measure static pressure before and after so you see the change, not just hear about it.

No. Our equipment is HEPA-contained and vented outside. You may hear compressor noise and feel temporary airflow changes as we seal registers for zone-by-zone extraction. Most homeowners in Leon Valley and Helotes work from home through the process. We do ask that pets be secured away from the work area for their safety and ours.

We run Rotobrush brush-and-vac systems for flexible ductwork common in post-1980s San Antonio construction, and Nikro portable HEPA collectors for tighter access or sensitive finishes. For commercial jobs and rigid metal trunk lines, we deploy Abatement Technologies negative-air machines that maintain containment throughout the building. The right tool for the duct type matters more than brand loyalty.

Yes, as a separate service with its own flat-price quote. Dryer vent buildup is a leading cause of house fires, and San Antonio's hard water minerals combine with lint to form dense blockages in longer vent runs. We use rotary brush systems and airflow meters to verify restoration to manufacturer-specified exhaust rates. We do not bundle it into duct cleaning without your explicit approval.

We do not disturb asbestos-containing materials. If your San Antonio home was built before 1985 and has original duct insulation, we inspect first and refer to certified abatement contractors if friable material is present. Our crews are trained to recognize suspect materials and stop work rather than risk fiber release. Documentation of what we found and why we paused is part of your record.

Every pro working under our name is required to hold the license and insurance Texas requires for HVAC and duct cleaning work. We carry general liability and workers' compensation coverage, and our license numbers are available on request. Haven Clause 3 means background-checked crews, and we put the lead technician's name in your confirmation text so you know who arrives.

Standard residential duct cleaning does not require a permit in San Antonio or Bexar County. If our inspection reveals that duct modification, re-routing, or significant repair is needed, we advise on permit requirements and can refer you to licensed HVAC contractors for that scope. We do not perform work that triggers permitting without ensuring compliance.

We are independently owned and operated here in San Antonio, led by Tomas Reyes, and part of the CleanRun Air Duct Cleaning brand that has served over 52,000 homes since 2013. The Haven Standard, our documentation system, and our equipment purchasing power come from the brand. The local knowledge, the trucks you see on 1604 and I-10, and the relationships with homeowners in Kirby and Selma are ours.

We are not an emergency response service. Our hours are Monday through Friday 7:30 AM to 7:30 PM, Saturday 8:00 AM to 6:30 PM, and Sunday 8:00 AM to 6:30 PM. If you have a true HVAC emergency, like no cooling in August or a suspected gas leak, contact your HVAC contractor or utility provider first. We schedule diagnostic and cleaning appointments within those hours, typically within a few business days depending on season.

Turn off your system and call your HVAC contractor or fire department if the smell is acrid or persistent. Dust burning off a heat exchanger after long disuse is common and usually harmless, but electrical odors or melting plastic require immediate professional assessment. Once the hazard is cleared, we can inspect and clean the ductwork to remove residual contamination. Our role starts after safety is confirmed.

Yes, and for allergy-sensitive households, timing cleaning before peak cedar and oak seasons in December through March can reduce initial allergen load. We seal the system during work and use HEPA containment, so outdoor pollen does not enter during the process. Many Windcrest and Alamo Heights homeowners schedule in October and November for this reason.

Every job carries a written warranty against workmanship defects, documented on your invoice. If we missed a run, damaged a register, or left debris behind, we return and correct it at no charge. Haven Clause 1 requires the scope and price in writing before work starts; Haven Clause 4 requires the evidence that proves completion. The warranty is in that same document.

You receive dated before-and-after photos of every run we accessed, plus static pressure readings if applicable. In 13 years, CleanRun has photographed the inside of every duct run on every job, because that is the only way a customer can tell the difference between real work and a vacuum noise. Your documentation is your proof, not our word.

Contact us within 30 days. We review your documentation, re-inspect if needed, and correct any deficiency under our workmanship warranty. Haven Clause 5, No Surprises, means we do not argue about whether the work happened; we look at the photos and readings together and resolve it. Our reputation in San Antonio depends on homeowners in Terrell Hills and Leon Valley recommending us without reservation.

We guarantee that we cleaned what we scoped, documented what we found, and left the system as described in your written agreement. Indoor air quality depends on many factors beyond duct cleanliness: filtration, humidity control, source removal of contaminants, and building envelope integrity. We advise honestly on what duct cleaning can and cannot address, and we document our actual results rather than promise outcomes we cannot control.
