About our AHU cleaning in Woodside
Our AHU cleaning covers sites in Woodside and the rest of Hampshire, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers supply and extract fans, internal panels and filter sections, and common reasons people get in touch are plant that needs cleaning after a refit and drain trays holding standing water.
For a building in or near Woodside, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: dated, with photos, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Part by part
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and clean the filter housing.
Ventilation in Woodside buildings
Woodside is within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours.
Ventilation work in and around Woodside is risk-based: inspect, then clean what needs it. School buildings such as Vernham Dean Gillum's Church of England Primary School are usually done in the holidays, so classrooms are not disturbed.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- How easy every part is to reach
- The condition we find in the survey
- Parking and loading at the site
- Site requirements such as sign-in and permits
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.
Asking for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
We don’t publish a price list, because no two systems are the same. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To get going, call us on 0345 646 2711, or send details by email.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Don’t ignore odours coming through the grilles
- File each AHU report in the maintenance log
- Stick to the filter change plan
- Diary the inspection date recommended in the report
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. In a small place like Woodside, the journey is planned ahead and the visit arranged around the site’s hours.
- 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.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Allow time for equipment near the work to be turned off and cool down
- Tell us where we can park and unload

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

FAQs for Woodside
Can you work in Woodside outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Woodside needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Is AHU cleaning available in Woodside?
Yes. We work across London and the South East, and Woodside is part of that. You can call us on 0345 646 2711 or use the quote form and let us know what needs doing.
Where does the waste go?
It’s contained and taken away. We collect grease, debris and waste water as we go, so it doesn’t spread.
What if parts of the system cannot be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
How far ahead should we book?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Why it’s worth doing now in Woodside
Dirt left in an air handling unit does not 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 Woodside is easier to arrange than an emergency callout.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

When it’s something else
In fairness, some problems need a different fix:
- A system that’s undersized for the building
- Problems with the unit’s controls or sensors
- Damaged coils beyond cleaning
If you’re not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer before you book.
