About our AHU cleaning in Somerley
No two plant rooms are the same, from a small ceiling-mounted unit to a large rooftop plant. We look at the unit first, from photos or a site visit, and send you a fixed quote before any cleaning starts. The work covers heating and cooling coils, internal panels and drain trays, and the jobs we see most are air handling units never cleaned inside and air handling units with blocked filters.
Work in a small place like Somerley starts with agreeing access and timings.
A written report with pictures follows each visit, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
How we price AHU cleaning
Your quote is based on your site. We consider:
- What state the system is in
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
Helping us quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Photos showing the whole system and its surroundings
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, call 0345 646 2711 or send us an email.
How it works
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. The work itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Pictures of the system and its access let us plan the work in Somerley before we set off.
- 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.
- We take after photos and issue the certificate and report.
How to prepare
- Clear the space around the work
- Agree a time when the area can be out of use
- Find the previous report, if there is one
How to get a quote
To get a fixed quote, give us a ring on 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You’ll typically have a quote within one working day.

Your questions about AHU cleaning in Somerley
Do you work at weekends in Somerley?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
Will you come out to Somerley?
Yes. Villages and rural sites across the South East are part of our work, Somerley included. Photos of the system and directions to the site help us plan the visit.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line, for problems that cannot wait. Ring any time and tell us what’s happened.
Are you insured?
Yes. We are fully insured, and the details are available on request.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Can you quote from pictures?
Yes, if we can see what we need. If not, a site survey comes first, then a fixed quote.
Will the ventilation be off while you clean?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Managing agents and facilities teams in Somerley
Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Work can be phased by floor, building or site around the people who use them.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
How the job changes from site to site
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Drain trays
The drain tray collects water from the cooling coil. Standing water and slime are removed and the outlet is checked.
Ventilation in Somerley buildings
Food Standards Agency data includes about 3 hospitals, care homes and childcare premises in and around Somerley, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 5.2 miles north-east of Somerley is St Richard's Hospital, the nearest hospital. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. At about 59 miles from central London, Somerley sits well inside the area we cover. The visit is fixed around your opening hours, not ours.
For schools like Birdham CE Primary School, the holidays are the usual time to inspect and clean ventilation.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- File each AHU report in the maintenance log
- Clear leaves and litter away from the intake
- Do not ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

What we are called out for in Somerley
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Clients normally contact us when they notice something like this:
- Condensate trays that will not empty
- Air handling units never cleaned inside
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
Hospitals such as St Richard's Hospital (about 5.2 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Somerley are no different.
