How the job changes from site to site
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.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
About our AHU cleaning in Braishfield
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. If you have dirty filters cutting the airflow and dirty coils holding back the airflow, we can help.
Work in a small place like Braishfield starts with agreeing access and timings.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What a clean won’t put right
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Coils that are corroded or leaking and need replacing
- The supply and extract ducts, quoted separately
- Building management system faults
If in doubt, call us on 0345 646 2711 or drop us a line and we will say what we think.
Where we work
- Internal panels
- Filter sections
- Supply and extract fans
- Heating and cooling coils
- Drain trays
- Dampers and louvres
How it works
Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the AHU cleaning, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. We agree a date with you, plan the drive to Braishfield and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Before we arrive
- Let us know about parking and loading
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
To get a fixed quote, give us a ring on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.

Also in Braishfield
Do you need AHU cleaning in Braishfield?
Filters that aren’t changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.
Any of these means the system needs a check-up:
- Condensate trays that will not empty
- Leaves and litter drawn into the unit
- Odours coming through the supply air
- Dust-coated heating and cooling coils
Romsey Community Hospital, about 2.2 miles south, is the nearest hospital to Braishfield, and healthcare sites of every size need their supply air kept clean.
Before booking anyone
- What insurance they carry
- Whether VAT is included
- Whether a survey comes first
- Proof of accreditation you can verify
Looking after it afterwards
Here’s the after-treatment advice, short and simple:
- Change filters on schedule and log each change
- Store the TR19 paperwork where auditors can find it
- Plan the next inspection before the last report gets filed away
- Look at the condensate drain whenever the unit is serviced
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
Questions from Braishfield
Do you cover Braishfield for AHU cleaning?
Yes, we work in Braishfield and the places around it. Just give us a ring on 0345 646 2711, or email photos with a few details of the site.
Can you come to Braishfield after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Can you fix a faulty AHU?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
What do you do with what you remove?
It leaves the site with us when we go. During the work, it’s contained to keep the area clean.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
Do you do ventilation duct cleaning too?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can survey both on the same visit.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

- The times the site is available
- Travel, parking and unloading

The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- When the site is open and when it’s quiet
- The paperwork from the last visit, if you have it
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
