Landlords, agents and facilities managers
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.
We also work for facilities teams across offices, schools and healthcare in Marchwood and across Hampshire. Work can be phased by floor, building or site around the people who use them.
AHU cleaning in Marchwood
Where a building in Marchwood has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. Common call-outs are for blocked condensate drains and slimy trays and fan sections that haven’t been cleaned in years, on heating and cooling coils, drain trays and internal panels.
Smaller buildings around Marchwood often keep their ventilation units in a roof void or plant cupboard, out of sight and easy to overlook. Every unit, large or small, has filters, coils and a drain tray to keep clean.
A written report with photos 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.

What AHU cleaning looks like in Marchwood
Food Standards Agency records list about 3 schools, colleges and universities and about 5 caring premises (care homes, nurseries and hospitals) registered as food businesses in and around Marchwood, up to about a mile and a half out. Buildings like these often rely on mechanical ventilation, which TR19® Air covers. The nearest hospital to Marchwood is Western Community Hospital, about 2.3 miles north. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For schools like Marchwood Junior School, the holidays are the usual time to inspect and clean ventilation.

What staff can safely do
Staff cleaning and specialist work aren’t the same thing. 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. That part needs specialist access and equipment.
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.
How the job changes from site to site
Internal casing and panels
We open each section through its doors and close them securely when we are done, and check every one is shut.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with photos so repairs can be planned.
What affects the quote in Marchwood
The survey tells us what the work involves. We look at:
- Site rules, permits and inductions
- How many systems or sites are involved
- The condition we find in the survey
- The scale of the work
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
What we need to know
Photos let us diagnose from a distance. The most useful are:
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- Where the site is and what kind of site it is
- A few general shots of the system
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or drop us a line.
Why deal with it now?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, particularly where damp has made it stick. It’s better to plan the work at a site near Marchwood than wait for a failure.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before work begins.
Why book with us
- We diagnose before we treat
- We’re fully insured
- Accredited under CHAS and SafeContractor, with ISO 9001
- Out-of-hours work and a 24/7 emergency line
Your questions about AHU cleaning in Marchwood
Do you cover smaller places like Marchwood?
Yes. Marchwood is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can you work in Marchwood outside opening hours?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
Can you quote from pictures?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. Some sites still need a visit, and we will say so.
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.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
Can we book visits on a schedule?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
How far ahead should we book?
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.

What we’re called out for in Marchwood
Air handling units are usually tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
These are the problems we see most often:
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
Healthcare ventilation, from large hospitals like Western Community Hospital (about 2.3 miles north) to small clinics, depends on clean filters, coils and ducts.
Before booking anyone
- Which accreditations they hold, and whether you can check them
- Whether a written report and photos are included
- Whether inaccessible sections are listed on the report
- When they can work, and whether that’s outside your opening hours
How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on.

- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
