FAQs
What does it mean that your technicians are NADCA-certified?
NADCA (National Air Duct Cleaners Association) certification is the industry’s gold standard. To earn it, our Church Hill technicians passed rigorous exams on HVAC hygiene, adhere to NADCA’s ACR cleaning standard, and follow a strict code of ethics. When you hire us, you’re guaranteed trained professionals who use approved equipment, maintain safety protocols, and provide thorough documentation of every cleaning.
How often should I have my air ducts cleaned in Church Hill’s climate?
For most homes in Church Hill, we recommend a full duct cleaning every 3–5 years. However, you may need more frequent service if you’ve recently completed renovations, live with pets that shed, have household members with allergies or asthma, or notice visible dust and debris coming from registers. Commercial facilities with higher occupancy or specialized processes often schedule annual or bi-annual cleanings to stay compliant with indoor air quality guidelines.
What signs indicate my HVAC system needs duct cleaning?
Common indicators include: visible dust puffs when the system cycles on, musty or stale odors, uneven airflow from registers, a recent spike in utility bills, or finding excessive dust on furniture shortly after cleaning. Allergy flare-ups or unexplained respiratory issues can also point to contaminated ductwork. A quick inspection by our NADCA-certified crew can confirm whether a cleaning is necessary.
What exactly is included in your duct cleaning service?
Our standard package covers a complete source-removal cleaning: 1) Pre-inspection and digital photo documentation of supply and return ducts; 2) Removal and ultrasonic cleaning of registers and grilles; 3) High-powered negative-pressure vacuuming of the entire duct network; 4) Agitation with rotating brushes and compressed-air whips to dislodge debris; 5) Cleaning of the blower, evaporator coil, and accessible HVAC components; 6) Optional EPA-registered antimicrobial fogging if requested; 7) Post-cleaning photos and a written report for your records.
How long does a typical residential duct cleaning take, and will it disrupt my day?
Most single-family homes in Church Hill take 2–4 hours to complete, depending on square footage and duct complexity. Our team protects flooring and furniture with drop cloths, works in discreet sections, and checks system operation before and after the job. You can remain in the house, and the HVAC system is usually back online within minutes of finishing.
Can duct cleaning really improve indoor air quality and reduce energy costs?
Yes. Removing accumulated dust, pollen, pet dander, and microbial growth lets conditioned air flow freely, easing the load on your blower motor. Studies cited by the EPA show that a clean system can run up to 20% more efficiently. Customers often report fewer allergy symptoms, less household dust, and lower monthly utility bills after service. While results vary, NADCA endorses duct cleaning as a key part of a whole-home indoor air quality strategy.
