Air Ventilation Supply and Extract Duct Cleaning: The Key to Healthy Indoor Air
Table of Contents
Are you concerned your home or workplace might be harbouring hidden dust, mould, and allergens in the air ducts? At Lex Hygiene, we specialise in Air Ventilation Supply and Extract Duct Cleaning—a crucial service for maintaining healthy indoor air quality. Whether you’re responsible for a residential space, commercial premises, or industrial setting, clean and efficient duct systems are essential.
1. What Is Air Ventilation Supply and Extract Duct Cleaning?
Air ventilation systems circulate fresh air in (supply) and draw stale air out (extract). Over time, these duct systems accumulate:
- Dust and debris
- Mould and fungal spores
- Grease (in kitchens)
- Allergenic particles (pets, pollen)
Supply duct cleaning ensures clean air is delivered into your living or working spaces.
Extract duct cleaning, meanwhile, ensures stale, moisture-laden air is properly removed—reducing condensation and damp issues.
2. Why You Should Prioritise Duct Cleaning
- Health & Air Quality: Dirty ducts can circulate dust, mould, bacteria, and allergens—exacerbating asthma, allergies, respiratory irritation, and overall asthma control.
- Energy Efficiency & Cost Savings: Clogged or contaminated ducts make fans and HVAC systems work harder, driving up energy usage and costs. A thorough clean restores airflow, increasing efficiency.
- Fire Safety (Kitchens & Extract Systems): In commercial kitchens, extract hoods can accumulate grease—a fire hazard. Regular cleaning mitigates risk.
- Compliance and Insurance: Many public/commercial buildings are required to maintain acceptable air quality as part of regulatory compliance. Regular duct cleaning helps meet building regulations and can strengthen insurance claims in case of incidents.
3. Our Professional Air Ventilation and Extract Duct Cleaning Process
At Lex Hygiene, we follow a rigorous seven-step process, designed to deliver excellence:
- Site Assessment & Planning – We survey the duct layout (supply and extract routes) and use data to scale our toolkit accordingly.
- High-Power Vacuuming – Using HEPA-filtered vacuums, we remove loose dust and debris from all ductwork, grills, and access panels.
- Abrasive or Rotary Brush Cleaning – We deploy specialist rotary brushes to dislodge deeper buildup.
- Sanitisation & Anti‑microbial Treatment – Optional disinfecting spray eliminates microbial residue and helps prevent mould regrowth.
- System Testing & Performance Check – We test airflows before and after to ensure efficiency.
- Reporting & Certification – Detailed before-and-after photos plus performance data and a cleaning certificate.
- Maintenance Scheduling – We recommend a cleaning interval—from one to three years depending on use. Residential may lean toward two-year cycles; commercial and hospitality quicker.
4. The Advantages of Clean Supply and Extract Ducts
- Improvements to Indoor Air Quality: Less dust, fewer allergies.
- Lower Energy Bills: Repaired system efficiency saves you money.
- Extended HVAC Lifespan: Less stress on motors and fans.
- Hygiene & Reputation: For businesses—especially hospitality and healthcare—clean air systems reflect standards of cleanliness and care.
5. When Should You Get It Cleaned?
- Routine maintenance for residential systems: every 2–3 years
- Higher-risk environments (e.g. food prep kitchens, wet areas, heavy occupancy): annually
- Signs you may need cleaning now:
- Visible dust on air vents
- Musty or stale odours
