Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. In a small place like Fittleworth, a system that fails can take a site out of use.
What you pay depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before work begins, so there are no surprises.

How we handle AHU cleaning in Fittleworth
Our AHU cleaning covers sites in Fittleworth and the rest of West Sussex, 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 drain trays, internal panels and heating and cooling coils, and common reasons people get in touch are dust built up on fan impellers and odours coming through the supply air.
In a village or hamlet like Fittleworth, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Common problems we fix in Fittleworth
Whatever surrounds a building in Fittleworth, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
The symptoms we’re asked about most are:
- Dust built up on fan impellers
- Units that have only ever had filter changes
- Leaves and litter drawn into the unit
- Blocked condensate drains and slimy trays
In Fittleworth, we look inside the system before deciding what needs cleaning.
Comparing quotes
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the quote shows VAT
- Whether inaccessible sections are listed on the report
- Proof of accreditation you can verify
What happens on the day
Your staff do not need to do much on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Somewhere as small as Fittleworth, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
- Agree a time when the area can be out of use
How to get a quote

Ventilation in Fittleworth buildings

When something else is needed
We’ll always give you a straight diagnosis, so here’s what AHU cleaning will not do:
- Airflow problems caused by the system’s design
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
If in doubt, call 0345 646 2711, or send details by email and we’ll say what we think.

- Supply and extract fans
Staff cleaning versus specialist work
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Fittleworth questions
Do you work overnight in Fittleworth?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Can you clean school ventilation in Fittleworth during the holidays?
Yes, holiday work suits schools best. Around Fittleworth, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. You can ring 0345 646 2711, or email photos with the dates the site is empty.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.
What information do you need?
A short description and a few photos plus the address and your hours. We will ask for anything else we need.
Do you clean the ductwork as well?
Yes. We reach the ducts through access panels, and any sections we cannot reach are noted in the report, and new panels can be fitted.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. Before we leave, we tidy up and clean down.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Aftercare tips
Results last longer with the right care. We suggest:
- File each AHU report in the maintenance log
- Stick to the filter change plan
- Watch for drips or damp patches near the plant
- Keep inspection doors on the unit in good order
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
