How we handle AHU cleaning in Holybourne
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Typical jobs include plant that needs cleaning after a refit and filters that are clogged or overdue, on heating and cooling coils, filter sections and supply and extract fans.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Your questions about AHU cleaning in Holybourne
Can you do AHU cleaning in Holybourne?
Yes. We work across London and the South East, and Holybourne is part of that. To start, ring 0345 646 2711 or send us an email with a few photos of the system.
Do you work at weekends in Holybourne?
Yes. We work evenings, overnight and at weekends. That way a site in Holybourne does not have to lose a day’s trading. Just phone us on 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
Is a quote from photos possible?
Often, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Do you clean the ductwork as well?
Yes. Ventilation ductwork cleaning to TR19® Air is part of what we do. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Where does the waste go?
We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
AHU cleaning around Holybourne
Going by the FSA’s register, there are about 5 caring premises (care homes, nurseries and hospitals) and about 3 hotels and B&Bs serving food in and around Holybourne, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. About 44 miles out from central London, Holybourne is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site. About 2.4 miles south-west of Holybourne is Alton Community Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital.
Healthcare ventilation, from large hospitals like Alton Community Hospital (about 2.4 miles south-west) to small clinics, depends on clean filters, coils and ducts.
Holybourne is about 2 miles north-east of Alton, in Hampshire.

Keeping the system healthy
No system stays clean for ever, but care slows the build-up. Our tips:
- Make sure the unit’s access doors open easily
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Look at the condensate drain whenever the unit is serviced
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
What a clean won’t put right
We’d rather tell you now than book work that will not help, so here are the limits:
- Damaged coils beyond cleaning
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
If in doubt, call 0345 646 2711 or send us an email and we’ll say what we think.
What the work covers
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Filter sections
- Internal panels
- Drain trays
For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Larger estates can be phased building by building to keep disruption down.

When to call us in Holybourne
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, building up layer by layer.
Any of these means the system needs a check-up:
- Stale or musty smells from the ventilation
- Intake sections clogged with outdoor debris
- Air handling units due a clean after building work
- Dirty fans and fan housings
Classrooms and halls at schools such as Andrews' Endowed Church of England Primary School are easiest to work in when pupils are away.
Before booking anyone
- When they can work, and whether that’s outside your opening hours
- How areas they cannot reach will be recorded
- When the next visit should be, and why
- Whether the quote shows VAT
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes half a day to a full day per unit, with large plant planned over several shifts. Rural roads and tight entrances are worth telling us about before a visit to Holybourne.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
Getting ready for the visit
- Move anything stored near the system
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool

Why act early in Holybourne
Dirt left in an air handling unit does not stay in the unit. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. Our emergency line runs 24/7, but a planned visit to Holybourne is calmer for everyone.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, give us a ring on 0345 646 2711 or send us an email, and we’ll talk you through it.

What the work involves, part by part
Rooftop and plant room units
