Rotherbridge AHU cleaning
Our technicians work in Rotherbridge on cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Fixed quotes, work around your opening hours and photo reports as standard.

- Dust-coated heating and cooling coils
How we handle AHU cleaning in Rotherbridge
Units vary a lot in size, age and layout, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and give you a fixed quote, so you know where you stand. If you have plant that needs cleaning after a refit and filters that are clogged or overdue, we can put it right.
Somewhere as small as Rotherbridge, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

Do you need AHU cleaning in Rotherbridge?
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Rotherbridge, that’s air they breathe for hours at a time.
Keep an eye out for any of the following:
- Dirty fans and fan housings
- Blocked condensate drains and slimy trays
- Rooms that smell stuffy when the system runs
- Intake sections clogged with outdoor debris
Healthcare buildings such as Midhurst Community Hospital, about 5 miles west, depend on their ventilation; if you manage a surgery, clinic or care home near Rotherbridge, yours matters too.
Before you book anyone
- How areas they can’t reach will be recorded
- Whether the quote is based on a survey or photos
- Which accreditations they hold, and whether you can check them
- Whether the whole system is included, or only the parts that are easy to reach

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Rotherbridge buildings and their air
Going by the FSA’s register, there are about 3 care, childcare and hospital premises serving food across Rotherbridge and its immediate surroundings (about a mile and a half). Busy, occupied buildings like these are where clean supply air matters most. Rotherbridge is about 43 miles from central London, well within the area we cover across London and the South East. Evening, overnight and weekend visits are all possible. The nearest hospital to Rotherbridge is Midhurst Community Hospital, about 5 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Classrooms and halls at schools such as Petworth Cof E Primary School are easiest to work in when pupils are away.

How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes a single shift for a typical unit, longer for large or heavily soiled ones. A quick note on how to find the site and where to park makes a visit to Rotherbridge run smoothly.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Agree a time when the area can be out of use
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
Related advice
Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
Part by part
Rooftop and plant room units
Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
FAQs for Rotherbridge
Can you do AHU cleaning in Rotherbridge?
Yes, Rotherbridge is covered. Get in touch with the details and we’ll arrange a survey.
Can the work in Rotherbridge be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Rotherbridge needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Can you price the work without visiting?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote typically follows within one working day. If pictures aren’t enough, we’ll survey first.
What do you do with what you remove?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it does not spread.
Leave it or put it right?
Dirt left in an air handling unit doesn’t 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. A planned visit to Rotherbridge is easier to arrange than an emergency callout.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Keeping the system healthy
How long the results last depends on use and care. Here’s what we suggest:
- Don’t store bins or materials near the intake
- Keep the certificate and photo report with the plant records
- Report water on the plant room floor
- Report stiff or damaged access doors
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
