About our AHU cleaning in Faygate
Every supply and extract system relies on the air handling unit at its centre: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for blocked condensate drains and slimy trays and air handling units never cleaned inside, across internal panels, dampers and louvres and heating and cooling coils.
For a building in or near Faygate, access is agreed in advance and the visit is planned around the journey.
The sign-off is always in writing: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Do you need AHU cleaning in Faygate?
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Faygate, that’s air they breathe for hours at a time.
Most sites get in touch when they notice one of these:
- Units needing a clean before a new tenant or handover
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
If you run a surgery, dental practice or care home near Faygate, clean ventilation matters as much to you as to a hospital like Crawley Hospital (about 3.2 miles north-east).

FAQs for Faygate
Do you work in villages like Faygate?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Do you work at weekends in Faygate?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Faygate needn’t be disturbed. Tell us your opening hours when you ask for a quote.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Which sectors do you work in?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.
What’s included in an AHU clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
What happens if you cannot reach some of it?
We record them on the report, with a note of where it is, and we tell you what would make it reachable, for example new access panels.
Is there a report after cleaning?
Yes. Every clean comes with a TR19® certificate and a photo report. Keep them in the maintenance log.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Fixed quotes for AHU cleaning in Faygate
Every site gets its own quote. This is what makes a difference:
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
- Travel, parking and unloading
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll talk you through it.
Helping us quote
We can often survey from pictures. The most useful are:
- The postcode and the type of business
- Problems your staff have spotted
- Any previous report or certificate
- Photos showing the whole system and its surroundings
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before any work starts.
How it works
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes a single shift for a typical unit, longer for large or heavily soiled ones. Somewhere like Faygate, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- 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.
Getting ready for the visit
- Let us know about parking and loading
- Clear the space around the work
- Let us know when the site is closed or quiet
Getting a quote
Getting a quote does not take long. Call or email with a few details and you’ll normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Between visits
To keep the system working properly between visits:
- Plan the next inspection before the last report gets filed away
- Change filters on schedule and log each change
- Note any water around the unit or leaks below it
- Don’t ignore odours coming through the grilles
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

What you pay reflects the actual work. That is why we survey first, from photos or on site, and the price is agreed before any work starts.

How the job changes from site to site
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.
Internal casing and panels
The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.
