- Dirty coils holding back the airflow
- Intake sections clogged with outdoor debris
- Condensate trays that won’t empty
Between visits
A little care between visits keeps the system in better shape. We recommend:
- Do not store bins or materials near the intake
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
- Report water on the plant room floor
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
AHU cleaning in Great Holland, done properly
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. We’re often asked to deal with blocked condensate drains and slimy trays and dust-coated heating and cooling coils, across filter sections, internal panels and dampers and louvres.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

AHU cleaning in Great Holland: local notes
There are about 3 schools, colleges and universities and about 4 hospitals, care homes and childcare premises on the FSA’s food hygiene register across Great Holland and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.
Wherever a school like Kirby Primary Academy has ducted ventilation, a half-term visit keeps the work out of lesson time.

The process
A visit follows the same order every time: protect the area, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and leave you the report. On site, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere like Great Holland, lanes, gates and parking are worth mentioning in advance.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Getting ready for the visit
- Move anything stored near the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system

Different parts, different methods
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Fans and fan sections
The fan section is cleaned with the unit switched off and isolated in agreement with the site.

When to call us in Great Holland
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Clients normally contact us after spotting something like this:
- Filters that are clogged or overdue
- Coils clogged with dust and debris
- Odours coming through the supply air
- Condensate trays that will not empty
If you run an office near Kirby Cross station, its supply ductwork can gather dust for years before anyone looks inside.

Your questions about AHU cleaning in Great Holland
Can ventilation in schools around Great Holland be cleaned out of term?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 3 schools and colleges with food registrations within roughly a mile and a half of Great Holland. Send us your term dates when you call us on 0345 646 2711 or drop us a line, and we will fit the work in.
Do you work at weekends in Great Holland?
Yes, nights and weekends are routine for us. The work in Great Holland can fit around your hours. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Which parts of an air handling unit do you clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Do you give a certificate after the clean?
Yes, both a certificate and a report with pictures. The report also suggests when the unit should next be inspected.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Can you fix a faulty AHU?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too in Great Holland and across Essex. Work can be phased by floor, building or site to keep disruption down.
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
