How we handle AHU cleaning in Fair Oak
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. Typical jobs include filters that are clogged or overdue and dirty fans and fan housings, across filter sections, drain trays and supply and extract fans.
Around a place like Fair Oak, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Every visit ends with a written report and photos, 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.

Fair Oak buildings and their air
Going by the FSA’s register, there are about 4 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) serving food within 1.5 miles or so of the middle of Fair Oak. Busy, occupied buildings like these are where clean supply air matters most. The nearest hospital to Fair Oak is Moorgreen Hospital, about 2.7 miles south-west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
For schools like Fair Oak Junior School, the holidays are the usual time to inspect and clean ventilation. Healthcare buildings such as Moorgreen Hospital, about 2.7 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Fair Oak, yours matters too.

For landlords and multi-site operators
We also work for facilities teams across offices, schools and healthcare across Hampshire. Larger estates can be phased building by building to keep disruption down.
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
What a clean won’t put right
To be straight with you, there are a few things this work will not fix:
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly.
What the work covers
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Supply and extract fans
- Drain trays
Why it’s worth doing now in Fair Oak
Cleaning a unit while it only has light dust is quick. Years of build-up make the job longer and harder, particularly where damp has made it stick. Light use slows the build-up but does not stop it.
What you pay depends on the size of the system, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
Why book with us
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Fixed quotes, usually within one working day
- Work around your opening hours, with 24/7 emergency cover
- Every job surveyed first
See our cost guide and our accreditations.
What staff can safely do
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.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
How we price AHU cleaning
Every site gets its own quote. This is what makes a difference:
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- Where the site is and how we reach it
- How big the system is
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll explain each part.
Helping us quote
Photos let us diagnose from a distance. The most useful are:
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- The times we could work without disrupting the site
- The paperwork from the last visit, if you have it
Here’s what helps us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Then call us on 0345 646 2711, or email photos.
Fair Oak: your questions answered
Do you do school ventilation cleaning in Fair Oak in the summer holidays?
Yes, out-of-term visits are normal for schools. Around Fair Oak, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Just phone us on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you work overnight in Fair Oak?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Fair Oak needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
Do you need to switch the unit off?
Yes. We cannot clean a running unit, so it’s switched off and made safe first. The shutdown is planned with whoever runs the building.
Do you offer emergency callouts?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
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 so the quote reflects it.
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. The coil and its drain tray are cleaned as one job.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, and that takes from a few hours for a compact unit to a day or more for a large one. In a smaller place like Fair Oak, parking is rarely the issue, but tell us about gates, roof access and opening hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Plan for cooking equipment or plant to be off before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Let us know about permits to work or site inductions
How to get a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
