Common questions in Rowfant
Can the work in Rowfant be done at night or at weekends?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Rowfant needn’t be disturbed. Just give us a ring on 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Is AHU cleaning available in Rowfant?
Yes, Rowfant is within the area we cover across London and the South East. A fixed quote normally follows within one working day of the survey details.
Will we get paperwork for the AHU clean?
Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.
Are you fully insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call 0345 646 2711, or email photos and tell us about the site and its opening hours.
Do you look at the system first?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
How we handle AHU cleaning in Rowfant
We clean air handling units for buildings in Rowfant and across West Sussex, working to TR19® Air, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you’re dealing with dust-coated heating and cooling coils and units needing a clean before a new tenant or handover, we can put it right.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What we’re called out for in Rowfant
Whatever surrounds a building in Rowfant, the air drawn into its AHU carries dust, pollen and debris. Most of it lands at the intake and the first stage of filters, and the finer material travels on.
Signs it’s time to call us include:
- Intake sections clogged with outdoor debris
- Dirty fans and fan housings
- Air handling units with blocked filters
- Dust-coated heating and cooling coils

Why it’s worth doing now in Rowfant
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. Out of sight is the usual reason a rural system goes too long without attention.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What affects the cost of AHU cleaning
Every site gets its own quote. This is what makes a difference:
- The times the site is available
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
- How big the system is
You will not find a price list here, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or send us an email, and we’ll explain what it covers.
What we need to know
When you call or email, it’s useful to have:
- Detail shots of panels, filters and grilles
- The postcode and the type of business
- When the site is open and when it’s quiet
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quotes are quick. Send a few details and pictures, and we usually reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
Managing agents and facilities teams in Rowfant
Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Larger estates can be phased building by building around the people who use them.
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we are happy to quote for all of it.

How the job changes from site to site
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.
Looking after it afterwards
Once we have finished, these simple steps help:
- Report musty smells from the vents right away
- Keep filter changes on time and recorded
- Diary the inspection date recommended in the report
- Check the drain tray is emptying during routine visits
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.
