Frequently Asked Questions

Most residential air duct cleanings in Miami take 2.5 to 4 hours from arrival to final walkthrough. A typical 3-bedroom home in West Park or Miramar with 12–18 vents takes about 3 hours. Larger homes in Ives Estates with 25+ vents or systems with heavy mold remediation needs can run 4–6 hours. We don't rush — proper cleaning requires accessing every vent, agitating debris with mechanical brushes, and negative-pressure vacuum extraction. We'll give you a specific time estimate when you call (833) 628-3661.

We seal each vent, create negative pressure throughout your duct system, then use mechanical brushes and compressed air tools to dislodge debris while powerful vacuums extract it outside your home. In Miami's climate, we pay special attention to condensate lines and evaporator coils where humidity breeds mold. We finish with a camera inspection showing before-and-after footage. For homes in Lake Lucerne and Golden Glades near busy roads, we often find significant pollen and brake dust accumulation. The process is thorough but non-disruptive — you're welcome to stay home. Call (833) 628-3661 to schedule.

Every 3 to 5 years for most Miami homes, though annual cleaning is smart if someone has allergies, asthma, or you have multiple pets. In coastal neighborhoods like North Miami Beach, salt air accelerates corrosion and debris buildup, pushing some clients toward 2–3 year intervals. Post-hurricane or after major renovations in Carol City or Norland, we recommend immediate inspection. If you see visible dust puffing from vents, smell mustiness, or your energy bills spike unexpectedly, don't wait. Call (833) 628-3661 — we can assess whether you're due.

Yes — clean ducts can improve HVAC efficiency by 15–25% according to Department of Energy estimates, and we've measured similar results in Miami homes. Restricted airflow from debris buildup forces your system to run longer cycles, which is brutal during July and August when Miami heat indexes hit 105°F+. After cleaning ducts in a 2,400 sq ft home in Scott Lake last summer, the homeowner's next FPL bill dropped $47. Your mileage varies based on how dirty the system was, but the physics are clear: free airflow equals less energy waste. Call (833) 628-3661 for a free assessment.

Yes, significantly — most of our Miami customers report 60–80% less visible dust on surfaces within two weeks of cleaning. The dust you wipe off your Norland or Miami Gardens furniture isn't "normal Florida dust" — it's recirculated debris from your ductwork, including skin cells, pollen, fabric fibers, and outdoor particulates pulled in through your HVAC system. We remove the reservoir of accumulated debris so your filter can actually do its job instead of being overwhelmed. One Lake Forest client told us she stopped dusting twice weekly after our service. Call (833) 628-3661 to breathe easier.

We use Rotobrush brush-and-vac systems for residential ductwork, Nikro HEPA-filtered negative air machines for containment, and Honeywell air quality monitors to verify results after cleaning. For commercial jobs in Miramar and larger homes in Ives Estates, we deploy truck-mounted power vacuums with 15,000+ CFM suction. We don't use chemical "foggers" as a substitute for mechanical cleaning — that's a shortcut that leaves debris behind. Our equipment is serviced weekly in our Miami warehouse, not rented or shared with other contractors. Call (833) 628-3661 to ask about our current setup.

We use Guardsman mastic sealant for small duct leaks and joint repairs, applied after cleaning when we find separations in your ductwork. For larger breaches in flex duct common in 1980s–1990s Miami construction, we replace sections rather than patch. We don't upsell sealant as a miracle cure — it's a targeted repair for specific problems we document with camera footage. In Golden Glades and Andover, we've found that poorly installed original ductwork benefits more from proper sealing than from cleaning alone. We'll show you exactly what needs attention. Call (833) 628-3661.

Yes — Rotobrush systems are specifically designed to navigate flexible ductwork safely, and approximately 70% of Miami homes built after 1975 have flex ducts. We adjust brush speed and stiffness based on duct diameter and condition; in older Lake Lucerne homes with brittle flex duct, we use softer brushes and lower torque. Rigid metal ducts in pre-1970 homes near Scott Lake handle more aggressive agitation. We inspect with cameras before selecting tools, so there's no guesswork that could damage your system. Call (833) 628-3661 to discuss your duct type.

Yes — we're state-licensed and carry full general liability and workers' compensation insurance, which is legally required but surprisingly rare among Miami duct cleaning outfits advertising on social media. Florida doesn't require a specific "air duct cleaning license," but we hold HVAC contractor credentials that allow us to access and service your full system, not just vacuum vents. Always verify licensing before letting anyone cut into your ductwork. We've been called to fix damage from unlicensed operators in West Park and Carol City. Call (833) 628-3661 — we're happy to provide documentation.

Every technician is background-checked, drug-screened, and completes 120+ hours of hands-on training before working solo in Miami homes. Michael Brown personally trains new hires on Miami-specific challenges: hurricane debris infiltration, salt air corrosion patterns in coastal systems, and the particular mold strains common to our subtropical humidity. Our team averages 4+ years with us — low turnover means experienced techs who know your neighborhood's housing stock. In 11 years, we've never had a theft or damage complaint. Call (833) 628-3661 and ask for our team credentials.

No permit is required for standard residential air duct cleaning in Miami-Dade or Broward counties. If we discover and replace damaged ductwork during service, minor repairs typically don't trigger permitting either. However, full duct replacement or modifications to your HVAC system's electrical or gas connections do require permits and inspections — we handle that paperwork when applicable. We've navigated Miami-Dade's permitting process for larger projects in North Miami Beach and Miramar. For standard cleaning, we arrive and work same-day with no bureaucratic delay. Call (833) 628-3661 to schedule.

Yes — we offer same-day and next-day emergency service throughout Miami, Miami Gardens, Norland, and surrounding areas for situations like post-fire smoke damage, visible mold blooms, or severe pest infestation. During hurricane season, we prioritize flooded systems in Carol City, Lake Lucerne, and Golden Glades where standing water creates immediate mold risk. Our typical response for urgent calls placed before 2 PM is arrival within 4–6 hours. We don't charge emergency premiums for same-day scheduling — just standard rates. Call (833) 628-3661 now; if we can't get to you today, we'll tell you honestly when we can.

Visible mold spreading from vents, sewage backup into ductwork, post-fire smoke contamination, and dead animal removal are true emergencies requiring immediate professional attention. In Miami's humidity, a dead rodent in your Lake Forest ducts can create unbearable odor and bacterial contamination within 48 hours. We don't treat "I forgot to schedule before my in-laws arrive" as an emergency — but we do keep slots open for genuine crises. If you're unsure whether your situation is urgent, call (833) 628-3661 and we'll triage over the phone. Estimates are free, and we'll be straight about whether you need us today or can wait.

We cover all of Miami-Dade and southern Broward, including Norland, Scott Lake, Andover, Miami Gardens, Carol City, Lake Lucerne, Golden Glades, Ives Estates, Lake Forest, West Park, Miramar, and North Miami Beach. Our warehouse near Miami Gardens keeps us within 30 minutes of most listed neighborhoods during normal traffic. We don't charge travel fees for standard service areas — the quote you get is all-inclusive. For addresses outside our core zone, we'll tell you upfront if any additional travel time applies. Call (833) 628-3661 with your address for confirmation.

We guarantee your satisfaction for 90 days — if dust, debris, or odors return due to our workmanship, we'll re-clean at no charge. This covers mechanical cleaning quality, not new contamination from construction, flooding, or pest re-infestation. In Miami's environment, we can't guarantee you'll never need cleaning again, but we do guarantee we did the job right the first time. Our 4.9-star average across 867 reviews reflects how rarely warranty claims occur. We also warranty any duct repairs or sealant work for one full year. Call (833) 628-3661 for warranty documentation.

We don't invoice until you approve the results — walk through with our technician, review the before-and-after camera footage, and confirm you're satisfied before payment. In 11 years serving Miami, we've had fewer than 10 refund requests, and we honored each one without argument. If you notice dust blowing from vents or musty smells returning within 90 days, call (833) 628-3661 immediately. Michael Brown personally reviews every complaint and will either dispatch a senior tech to address the issue or process your refund. Our reputation in communities from Andover to West Park depends on your honest review.

We guarantee our cleaning removes visible mold and treats affected surfaces, but we cannot guarantee mold won't return if underlying moisture problems persist. In Miami's climate, mold regrows within weeks when humidity exceeds 60% and condensation collects in poorly insulated ducts — common in older homes near Scott Lake and Carol City. We identify and report moisture sources during cleaning (leaky condensate pans, unsealed returns, missing insulation) so you can address root causes. Some clients add whole-home dehumidification or UV light installation for long-term protection. Call (833) 628-3661 to discuss prevention options after your cleaning.
