FAQs
Why should I have my air-conditioning and heating ducts cleaned?
Over time, dust, pollen, mould spores, pet dander and even construction debris can accumulate inside your ductwork. Each time the system runs, these contaminants are circulated throughout your Bristol home or business, aggravating allergies, reducing air quality and placing extra strain on the HVAC blower. Professional duct cleaning removes this build-up, helping your family breathe cleaner air, protecting sensitive electronic equipment from dust and extending the lifespan of your heating and cooling components.
How often do Bristol properties typically need duct cleaning?
For most domestic properties we recommend a thorough cleaning every 3–5 years. However, Bristol’s damp maritime climate can encourage mould growth, and homes with pets, smokers or recent renovation work may need service every 2–3 years. Commercial premises, especially those that operate extended hours or produce airborne particles (e.g., salons, workshops), often benefit from annual inspections and cleaning. Our technicians can carry out a camera inspection to confirm whether a full clean is warranted.
What certifications do your duct-cleaning technicians hold?
All of our engineers are City & Guilds Level 2 or 3 qualified in Heating & Ventilation, hold Construction Skills Certification Scheme (CSCS) cards, and are trained to the latest BESA TR19 and NADCA ACR standards for duct hygiene. We are also SafeContractor-approved and carry full public liability insurance. These credentials ensure that every clean is performed safely, complies with UK Building Regulations Part F and meets the high standards expected by insurance companies and local authorities in Bristol.
What is included in your duct-cleaning process?
1) Pre-inspection with a high-definition duct camera to map contamination levels. 2) Isolation of the HVAC unit and covering of supply/return grilles to prevent dust migration. 3) Agitation using rotary brush and compressed-air whip tools sized to your ductwork. 4) Extraction with a HEPA-filtered negative-air machine positioned outside the property, capturing 99.97 % of particles down to 0.3 µm. 5) Optional antimicrobial fogging (DEFRA-approved biocide) to inhibit mould regrowth. 6) Post-clean verification, including before-and-after photos and an electronic cleanliness report for your records.
Will duct cleaning disrupt my home or business?
Disruption is minimal. A typical three-bedroom property takes 3–4 hours, while medium-sized commercial systems are usually completed outside core trading hours. Our team uses floor protection, corner guards and vacuum hoses routed through a single exterior door or window. Noise is comparable to a household vacuum cleaner, and there is no release of dust into occupied spaces thanks to sealed negative-pressure containment. We remove and replace all access panels and return your HVAC system to normal operation before leaving.
Can duct cleaning really improve energy efficiency and indoor air quality?
Yes. A 1 mm layer of dust on a heat-exchanger coil can reduce efficiency by up to 21 %. By restoring unrestricted airflow, your system achieves target temperatures more quickly, reducing run-time and lowering energy bills. Cleaner ducts also reduce the recirculation of allergens, mould spores and VOCs, which can alleviate respiratory symptoms and improve overall comfort. Many Bristol customers report noticeably fresher air and a reduction in odours immediately after our service.
