Frequently Asked Questions

We connect a high-powered negative air machine to your main trunk line, seal all registers, and use mechanical agitation tools, compressed air whips, or brush systems to dislodge debris from every run while suction pulls it out of your home. In Leesburg, we regularly find construction debris in newer South Riding builds, heavy pollen accumulation in homes near the Potomac River valley, and pet hair compaction in multi-dog households. Every run is photographed before and after. You receive the photo set and a post-cleaning airflow reading. The process takes 2.5-4 hours for most single-system homes.

You see the evidence. Haven Standard Clause 4 requires photographs and readings from every job: interior duct photos before agitation, interior duct photos after, plus static pressure or airflow readings where accessible. These are yours to keep. In 13 years, CleanRun has photographed the inside of every run on every job, because that is the only way a customer can tell the difference between real work and a vacuum noise. If a company won't show you your own ducts, you're buying a sound.

Every 3-5 years for most homes, sooner if you have pets, allergies, recent renovation, or visible dust at registers. Leesburg's pollen seasons, particularly oak and ragweed peaks, push some homeowners toward the shorter end of that range. Homes near active construction in areas like Lansdowne or One Loudoun also accumulate debris faster. We inspect first and tell you honestly if your system doesn't need cleaning yet. Call (571) 487-7204 for a no-pressure assessment.

Moderately, if your ducts were significantly obstructed. A 2009 NADCA study found clean systems can improve airflow efficiency, but duct cleaning is primarily an indoor air quality service, not an energy retrofit. Where we see real efficiency gains in Leesburg homes is when we find and seal disconnected trunk lines or collapsed flex duct during inspection, issues that leak conditioned air into attics or crawl spaces. We'll photograph any such findings and quote repairs separately if you choose.

Most single-system homes in Leesburg take 2.5 to 4 hours from arrival to final walkthrough. Dual-system homes or properties with attic and crawl space runs may extend to 5-6 hours. We schedule real windows, not all-day waits, and text when your technician is en route. Haven Standard Clause 2: arrive on schedule, with a named tech and a real window.

We run Rotobrush brush-and-vac systems for light residential buildup, Abatement Technologies portable HEPA negative air machines for heavier debris or post-construction cleaning, and compressed air agitation tools for stubborn compaction. The right tool depends on what your pre-inspection photos show. We don't guess, we look first. All equipment is maintained to manufacturer specs and HEPA-filtered to prevent recontamination of your home during extraction.

We do, and we recommend them for Leesburg homeowners with allergy sensitivity or homes where pets generate significant dander. Aprilaire whole-house media cleaners mount at your air handler and filter particles down to MERV 13, far beyond standard fiberglass throwaways. We quote these as optional add-ons with a second written price if your inspection suggests benefit, never as a door upsell. Haven Standard Clause 5 applies to every offer we make.

We use Guardsman professional-grade duct sealants and repair compounds when we find small leaks, disconnected joints, or deteriorating flex duct during cleaning. These are applied after debris removal, not as a substitute for mechanical cleaning. Any repair work is photographed, explained, and quoted in writing before application. We don't sell products, we solve problems and show you the evidence.

Every pro working under our name is required to hold the license and insurance Virginia requires for HVAC and duct cleaning work. We carry general liability and workers' compensation coverage, and your technician's license number is documented on your job record. Haven Standard Clause 3: verified crews, with credentials you can verify. We're independently owned and operated here in Leesburg, working to standards set by CleanRun Air Duct Cleaning.

Standard residential duct cleaning doesn't require a permit in Loudoun County. If our inspection reveals duct repairs, modifications, or full replacement that involves your plenum or air handler connections, we handle permit research and include any requirements in your written scope. Most Leesburg homeowners never need this step, but we check so you don't have to worry about it.

We don't advertise emergency duct cleaning because duct contamination is rarely an immediate safety hazard, it's a cumulative air quality issue. If you've had a sewage backup, pest infestation, or mold bloom that requires rapid response, call (571) 487-7204 and we'll schedule you as quickly as our current bookings allow. Our hours are Monday through Friday 7:00 AM - 8:00 PM, Saturday and Sunday 7:00 AM - 7:00 PM. A live coordinator answers during these hours and connects you with the local team.

Typically within 3-7 business days, depending on season. March through May and September through November book fastest in Leesburg due to allergy season demand. We don't manufacture urgency or claim "only two slots left." We tell you honestly when the next available window falls and whether a nearby date opened due to a reschedule. Haven Standard Clause 2: real windows, real information.

Call or text (571) 487-7204 with 24 hours' notice and we'll move you to the next available window that works. Same-day cancellations with less than 24 hours' notice may incur a fee, which we'll disclose clearly in your confirmation message. We respect your time and ask the same.

Every job carries a written satisfaction guarantee: if our post-cleaning photos and readings don't show measurable improvement in the runs we cleaned, we return and re-clean at no charge. Haven Standard Clause 1 puts the scope and price in writing before work starts; Clause 4 requires the evidence that proves it was done. The guarantee is documented on your invoice, not promised verbally and forgotten. CleanRun has maintained this standard since 2013 across 52,000+ homes.

We stop, photograph the finding, and explain your options before proceeding. Common discoveries in Leesburg include disconnected flex duct in attics, deteriorating duct board at plenum connections, or rodent entry points in crawl space runs. None of these are upsell opportunities, they're conditions that affect your system's performance. We quote any repair separately in writing, and you're free to decline and hire another contractor. Haven Standard Clause 5: no surprises means no pressure too.

We note your cleaning date and system details and send a courtesy reminder at 3 years, with no subscription or automatic booking. You're free to ignore it, schedule earlier if conditions change, or call us for a free re-inspection anytime. We don't lock you into contracts. The reminder is a service, not a sales funnel.

Yes, and you should. We email the full photo set and job summary within 24 hours of completion. Keep these with your home maintenance records, they're useful for future HVAC service calls, home sales, or warranty claims with your equipment manufacturer. The documentation is yours. We keep backup copies per our retention policy, but your primary record should live with you.

We guarantee we removed the debris that was in your ductwork when we arrived, documented by photo. We don't guarantee your home will stay dust-free forever, because dust enters from daily living, outdoor air, and your system's normal operation. What we deliver is a clean starting point and the evidence to prove it. Regular filter changes and proper system maintenance extend the benefit significantly.
