AHU cleaning for kitchens and businesses in St Leonards
We clean air handling units for buildings in St Leonards and across Hampshire, working to TR19® Air, in offices, schools, hospitals, care homes and retail. The work is timed around when the system can be switched off, including evenings, nights and weekends. Common call-outs are for air handling units with blocked filters and units that have only ever had filter changes, on dampers and louvres, drain trays and filter sections.
Around a place like St Leonards, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Internal casing and panels
Dust settles on every internal surface of the unit. Each section is cleaned from the intake through to the outlet.

For landlords and multi-site operators
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Honest limits
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, call 0345 646 2711 or send us an email and we’ll say what we think before you book.

The process
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. For a place like St Leonards, we load the van from the survey notes so the work can be done in one visit where possible.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Preparing for the visit
- Mention any parking or loading restrictions
- Let us know when the site is closed or quiet
- Mention any sign-in, permit or induction we need

Advice
Signs you need AHU cleaning in St Leonards
Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
Any of these means the system needs a check-up:
- Dust-coated heating and cooling coils
- Filters that are clogged or overdue
- Intake sections clogged with outdoor debris
- Dust built up on fan impellers
Hospitals such as St Leonard's Hospital (about 0.9 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near St Leonards are no different.

FAQs for St Leonards
Do you offer AHU cleaning in St Leonards?
Yes. Our area runs across London and the South East, St Leonards included. Get in touch with the details and we’ll arrange a survey.
Is St Leonards within the area you cover?
Yes, we work in villages as well as towns, and St Leonards is covered. Just mention lanes, gates or anything else about the site when you book.
How much notice should we give?
Earlier is better, especially for out-of-hours work. We typically quote within one working day, and emergencies are covered by our 24/7 line.
Can you quote from pictures?
Yes, where the pictures show enough. Otherwise, we book a survey at a time that suits the site, and the quote follows that.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How long does an AHU clean take?
As a guide, it takes half a day to a full day per unit, with large plant planned over several shifts. We plan the shutdown around that, out of hours if needed.
Is there a report after cleaning?
Yes, both a certificate and a report with photos. The report also suggests when the unit should next be inspected.
When should our AHU next be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
What your team can do, and what needs us
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Between visits
To keep the system working properly between visits:
- Note any water around the unit or leaks below it
- Stick to the filter change plan
- Keep the area around the fresh air intake clear
- Check the drain tray is emptying during routine visits
Restart the unit with your site team or maintenance contractor once we have finished. Check the drain tray is emptying over the first few days to make sure it stays clear.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
