Ventilation in College Town buildings
There are about 10 schools, colleges and universities, about 16 caring premises (care homes, nurseries and hospitals) and about 5 hotels and guest houses on the FSA’s food hygiene register within about 1.5 miles of central College Town. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. College Town’s nearest hospital, Frimley Park Hospital, is about 2.2 miles south-east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes. College Town is about 31 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
School buildings such as College Town Primary School are typically done in the holidays, so classrooms are not disturbed. Healthcare buildings such as Frimley Park Hospital, about 2.2 miles south-east, depend on their ventilation; if you manage a surgery, clinic or care home near College Town, yours matters too.

AHU cleaning for kitchens and businesses in College Town
If the units serving a building in College Town have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. The work covers dampers and louvres, drain trays and heating and cooling coils, and the jobs we see most are odours coming through the supply air and fan sections that haven’t been cleaned in years.
Around a place like College Town, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
A written report with pictures follows every visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
What a clean will not put right
To be straight with you, there are a few things this work will not fix:
- Ductwork downstream of the unit, which is a separate clean
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.
Parts of the system we cover
- Dampers and louvres
- Supply and extract fans
- Heating and cooling coils
- Internal panels
- Drain trays
- Filter sections
How the visit works
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. All told, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the journey to College Town and bring what the job is likely to need.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool

Advice
Signs you need AHU cleaning in College Town
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Most sites get in touch when they notice something like this:
- Air handling units with blocked filters
- Dust-coated heating and cooling coils
- Odours coming through the supply air
- Plant that needs cleaning after a refit
If you manage shops or offices close to Blackwater station, a TR19® Air inspection shows whether the ductwork needs cleaning.
Before booking anyone

- Whether the whole system is included, or only the parts that are easy to reach
Questions from College Town
Can ventilation in schools around College Town be cleaned out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 10 schools and colleges on the FSA’s register within roughly a mile and a half of College Town, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can you come to College Town after we close?
Yes, nights and weekends are routine for us. It means the site in College Town keeps running as normal. Your opening times are the first thing we ask for.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Do you need to switch the unit off?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
Multi-site and managed buildings
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
Whether it’s one building or many, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- File each AHU report in the maintenance log
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
- Don’t store bins or materials near the intake
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. A drain that is cleared early never gets to the slime stage.
