FAQs
Why is professional air-duct cleaning important for homes and businesses in Delano?
Delano’s hot, dusty summers and frequent agricultural activity push a lot of pollen, field dust, and outdoor contaminants into HVAC systems. When these particles settle in your supply and return ducts they recirculate every time the system runs, aggravating allergies, lowering indoor air quality, and forcing the equipment to work harder. Certified duct cleaning removes this buildup, helping your heating and cooling system operate more efficiently, reducing energy bills, extending equipment life, and giving you cleaner, healthier air to breathe.
How often should I have my ducts cleaned by a certified technician?
The National Air Duct Cleaners Association (NADCA) recommends a full duct inspection every 2 years and a complete cleaning every 3-5 years under normal conditions. In Delano we often suggest the shorter end of that range—about every 3 years—because wind-blown valley dust, nearby agriculture, and prolonged AC use tend to load ducts faster. You should also schedule a cleaning sooner if you’ve recently completed a remodeling project, moved into a previously occupied home, or notice visible dust plumes, musty odors, or an unexplained spike in allergy or asthma symptoms.
What warning signs indicate my ductwork needs cleaning now?
• Vents or registers show dark buildup or fuzzy clumps.<br>• You smell a persistent musty or dusty odor when the HVAC system turns on.<br>• Home gets dusty again just hours after cleaning.<br>• Family members experience worsened allergies, coughing, or sinus issues indoors.<br>• You hear rattling debris or see particles blowing from vents.<br>• Your energy bills have crept up even though thermostat settings haven’t changed.<br>If any of these are present, book a professional inspection—often the fix is a thorough duct cleaning combined with a new, properly rated air filter.
What does your Delano duct-cleaning service include?
1. Pre-visit phone consultation and transparent pricing. 2. On-site NADCA-certified technician walkthrough and camera inspection of supply, return, and trunk lines. 3. Sealing of registers, then connection of a high-powered negative-air vacuum to create containment. 4. Rotary brush and compressed-air whip agitation of each branch to dislodge debris while the vacuum extracts contaminants into HEPA-filtered bags. 5. Cleaning of blower compartment, evaporator coil surface, and return plenum as needed. 6. Optional antimicrobial fog treatment (eco-friendly, food-grade) to inhibit mold growth. 7. Final camera verification, filter replacement, and detailed report showing before-and-after images.
How long will the cleaning take and will it disrupt my day?
Most single-family homes in Delano take 2–4 hours, depending on square footage, the number of supply runs, and how heavily soiled the system is. Larger homes or commercial spaces can run 4–8 hours. Our crews arrive in clearly marked vans, lay down protective floor coverings, and use sealed containment so dust stays out of living areas. You can stay in the home during the service, and your HVAC system can typically be powered back on immediately afterward.
Are your technicians certified and insured, and what standards do you follow?
Yes. Every technician is NADCA-certified, EPA-section 608 licensed for refrigerant handling, and trained in OSHA safety protocols. We carry full liability and workers’ compensation insurance specific to HVAC and indoor air quality work in California. Our company adheres to NADCA’s ACR Standard (Assessment, Cleaning & Restoration) and uses HEPA-filtered negative-pressure vacuums to meet or exceed EPA guidelines for source removal. You receive documentation of certification, proof of insurance, and a written 100 percent satisfaction guarantee with every service.
