How the job changes from site to site
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Older trays can corrode and start leaking. We record their condition with pictures so repairs can be planned.
About our AHU cleaning in Frinsted
Our AHU cleaning covers sites in Frinsted and the rest of Kent, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. If you are dealing with drain trays holding standing water and rooms that smell stuffy when the system runs, we can help, from heating and cooling coils, dampers and louvres and filter sections onwards.
Work in a small place like Frinsted starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Your questions about AHU cleaning in Frinsted
Do you work at weekends in Frinsted?
Yes, nights and weekends are routine for us. It means the site in Frinsted keeps running as normal. Your opening times are the first thing we ask for.
Do you cover smaller places like Frinsted?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
How much does AHU cleaning cost in Frinsted?
Every site is different, so each gets its own fixed quote. For a quote, call 0345 646 2711 or email us with the site type, opening hours and a few pictures.
How long will the unit be out of action?
The work takes a single shift for a typical unit, longer for large or heavily soiled ones. Large plant can be split over several shifts, and you can call 0345 646 2711 or drop us a line to plan it.
Can you quote from photos?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
What a clean will not put right
Some problems need a different service or another trade:
- Building management system faults
- Dirty ducts beyond the unit itself
- Faulty motors, drives or bearings
If in doubt, give us a ring on 0345 646 2711 or send us an email and we’ll say what we think before you book.
Parts of the system we cover
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Internal panels
- Dampers and louvres
- Filter sections
For landlords and multi-site operators
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Common problems we fix in Frinsted
Filters that aren’t changed or cleaned on time clog up, which cuts the airflow and can let air slip round the filter. After that, the coils and fan collect what the filter should have caught.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Odours coming through the supply air
- Dirty coils holding back the airflow
- Plant that has been serviced but not cleaned
School buildings such as Milstead and Frinsted Church of England Primary School are normally done in the holidays, so classrooms aren’t disturbed.
Questions to ask before you book
- Which accreditations they hold, and whether you can check them
- If the quote is a fixed price or an estimate
- Proof of insurance
- Whether the work can be done while the site is closed
How the visit works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. Visits to a village like Frinsted are booked in advance, at a time that suits whoever runs the site.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Tell us where we can park and unload
- Let us know when the site is closed or quiet
Getting a quote
To help us quote: where the site is, what it is and its opening hours, pictures of the system and the last certificate or report, if there is one. Then call 0345 646 2711, or send details by email.
Advice
What affects the cost of AHU cleaning
You will get a fixed price before work begins. It’s based on:
- Access, including roofs, risers and ceiling voids
- Parking and loading at the site
- The times the site is available
- How big the system is
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.
Asking for a quote
When you contact us, it’s useful to have:
- Where the site is and what kind of site it is
- The times we could work without disrupting the site
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
Some systems can be priced from photos; 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 work begins.

Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
