What happens if it’s left?
Stuffy rooms and stale smells in a building in Blackgang can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. Out of sight is the usual reason a rural system goes too long without attention.
We don’t list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

How we handle AHU cleaning in Blackgang
Heating and cooling coils trap dust that gets past the filters. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins aren’t flattened. Common call-outs are for air handling units due a clean after building work and plant that has been serviced but not cleaned, on filter sections, internal panels and supply and extract fans.
Somewhere as small as Blackgang, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but those that do need it inspected and cleaned like any other.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

FAQs for Blackgang
Will you come out to Blackgang?
Yes. Villages and rural sites across the South East are part of our work, Blackgang included. Photos of the system and directions to the site help us plan the visit.
Can you work in Blackgang outside opening hours?
Yes, nights and weekends are routine for us. The work in Blackgang can fit around your hours. Let us know the hours you’re closed and we will book within them.
What do you clean inside the unit?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. The photo report shows each section before and after.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
How often do AHUs need cleaning?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we will talk you through the next steps.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes half a day to a full day per unit, with large plant planned over several shifts. A few pictures of the system help us make the most of a visit to a place like Blackgang.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Name a contact who can let us in at the agreed time
- Dig out any earlier paperwork for the system
Getting a quote
For a fixed quote, call us on 0345 646 2711 or send us an email and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

Fixed quotes for AHU cleaning in Blackgang
The price is fixed before any work begins. It takes into account:
- The number of sites or systems
- Where the site is and how we reach it
- The condition we find in the survey
- One-off work versus a regular cycle
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
- Wide pictures of the system and the area around it
- Any previous report or certificate
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call us on 0345 646 2711, or email photos.
Other services in Blackgang
Keeping the system healthy
To keep the system working properly between visits:
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
- Don’t ignore odours coming through the grilles
- Note any water around the unit or leaks below it
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Do you need AHU cleaning in Blackgang?
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Clients typically contact us after spotting one of these:
- Units that have only ever had filter changes
- Dirty fans and fan housings
- Intake sections clogged with outdoor debris
- Dirty filters cutting the airflow
If you run a surgery, dental practice or care home near Blackgang, clean ventilation matters as much to you as to a hospital like Whitecroft Hospital (about 5.7 miles north).
What to look for in a quote
- Whether the quote shows VAT
- What happens if part of the system can’t be accessed
- If the quote is a fixed price or an estimate
- Whether a survey comes first
Different parts, different methods
Rooftop and plant room units
Many AHUs sit on roofs or in plant rooms with limited access. We plan safe access as part of the survey, before we quote.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. Each section is cleaned from the intake through to the outlet.
Honest limits
We’d rather tell you now than book work that will not help, so here are the limits:
- Damaged coils beyond cleaning
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
If in doubt, ring 0345 646 2711, or send details by email and we will say what we think before you book.
