AHU Cleaning in Firle
AHU cleaning for commercial sites in Firle and across East Sussex. CHAS, SafeContractor and ISO 9001, and fully insured.
- Units that have only ever had filter changes
- Rooms that smell stuffy when the system runs
- Dust built up on fan impellers
Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Store the TR19 paperwork where auditors can find it
- Diary the inspection date recommended in the report
- Make sure the unit’s access doors open easily
- Do not ignore odours coming through the grilles
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due, rather than waiting for a problem.
AHU cleaning in Firle
Our AHU cleans for sites in Firle cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have plant that has been serviced but not cleaned and dust-coated heating and cooling coils, we can put it right, from supply and extract fans, filter sections and internal panels onwards.
In a village or hamlet like Firle, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- Whether several sites go on one quote
- What state the system is in
- Access, including roofs, risers and ceiling voids
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, ring 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What to send for a quote
To help us quote quickly, send us:
- The times we could work without disrupting the site
- How we’d reach plant on a roof or in a plant room
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
How the job changes from site to site
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
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.
Firle questions
Do you work overnight in Firle?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Firle needn’t be disturbed. Tell us your opening hours when you ask for a quote.
Will you come out to Firle?
Yes, Firle is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How long will the unit be out of action?
The work takes one overnight shift for many single units, with bigger plant phased. Bigger units can be phased, and you can call 0345 646 2711, or email photos to plan it.
What about areas you cannot get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, plus photos of the system and your last certificate or report if you have one.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What we do, step by step
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. In a small place like Firle, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Preparing for the visit
- Find the previous report, if there is one
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
Ask for a quote
To get a fixed quote, call us on 0345 646 2711 or use the quote form and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. You’ll normally have a quote within one working day.

Why act early in Firle
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A planned visit to Firle is easier to arrange than an emergency callout.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll talk you through it.

For landlords and multi-site operators
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
