Air handling unit cleaning in Offham, Kent

- Air handling units due a clean after building work
- Dust-coated heating and cooling coils
- Intake sections clogged with outdoor debris
Common problems we fix in Offham
Filters catch most of the dust, but not all of it. What gets through settles on coils, fans and the inside of the casing, a little more each month.
Signs it’s time to call us include:
- Coils clogged with dust and debris
- Leaves and litter drawn into the unit
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
Healthcare buildings such as Maidstone Hospital, about 4.8 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Offham, yours matters too.
Questions to ask before booking
- What insurance they carry
- How they set the interval to the next visit
- Whether the work can be done while the site is closed
- Whether the price is fixed
AHU cleaning in Offham, done properly
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. The work covers filter sections, dampers and louvres and supply and extract fans, and common reasons people get in touch are units needing a clean before a new tenant or handover and filters that are clogged or overdue.
Work in a small place like Offham starts with agreeing access and timings.
Each visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site
Fans and fan sections
Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
Between visits
Think of this as the after-treatment advice, short and simple:
- Make sure the unit’s access doors open easily
- Store the TR19 paperwork where auditors can find it
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
When we’ve closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.
Change or clean filters on time. Once filters clog, dirt starts getting past them.

FAQs for Offham
Can you clean school ventilation in Offham during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 6 schools and colleges with food registrations within roughly a mile and a half of Offham. Send us your term dates when you call 0345 646 2711 or email us, and we will fit the work in.
Do you cover smaller places like Offham?
Yes. Villages and rural sites across the South East are part of our work, Offham included. A survey first, from photos or a visit, means we arrive with the right kit.
Is there a report after cleaning?
Yes. You get a TR19® certificate plus before and after pictures. They’re worth keeping with the plant records.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. What happens to the filters is agreed when we quote.
How do you protect the area?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Do you repair air handling units?
We clean the unit and flag faults rather than repair them, with pictures where it helps.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends to keep disruption down.
Managing agents and facilities teams in Offham
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Facilities teams in offices, schools and healthcare sites book us too across Kent. Larger estates can be phased building by building around the people who use them.
How we price AHU cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- The condition we find in the survey
- The times the site is available
- Where the site is and how we reach it
- How easy every part is to reach
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Close-ups of filters, grilles, hatches or access panels
To get a fixed quote, give us a ring on 0345 646 2711 or email us with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
The process
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Offham, the date and timings are agreed with you well before the day.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- 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.
Before we arrive
- Clear the space around the work
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
