Pennington AHU cleaning
AHU cleaning for Pennington, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.

- Fan sections that haven’t been cleaned in years
How we price AHU cleaning
Sites vary more than people expect. The main factors:
- The scale of the work
- Whether several sites go on one quote
- The times the site is available
- Access, including roofs, risers and ceiling voids
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. We give you a fixed price before work begins, so you know where you stand.
What to send for a quote
Before you ask for a quote, gather:
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- Your opening hours and when the area is out of use
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
How we handle AHU cleaning in Pennington
Think of an AHU clean as a full check-up for the ventilation. We look inside each section, clean what we find and record it with photos, so you can see the unit’s condition for yourself. Typical jobs include odours coming through the supply air and intake sections clogged with outdoor debris, on internal panels, dampers and louvres and drain trays.
In a smaller place like Pennington, buildings with ducted ventilation are more likely to be a school, a surgery, a care home or a small business unit than an office block. Even a small system collects dust in its ducts and filters.
The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What happens if it’s left?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, ready to show anyone who asks. In a smaller place like Pennington, a site that has to close is felt quickly.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and the price is agreed before any work starts.

Landlords, agents and facilities managers
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
The process
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, 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. Tell us about any gates, ladders or locked plant areas at your site near Pennington when you book.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
How to get a quote
To get a fixed quote, call us on 0345 646 2711, or email photos 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 will typically have a quote within one working day.

What the work involves, part by part
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Drain trays
Condensate from the coil drips into a tray beneath it. We clear standing water, clean out slime and check the outlet is draining.
What AHU cleaning cannot fix
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Breakdowns that need a mechanical engineer
- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
If you are not sure, just call us on 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.
Where we work
- Supply and extract fans
- Heating and cooling coils
- Dampers and louvres
- Filter sections
- Internal panels

What your team can do, and what needs us
Staff cleaning does not 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.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
AHU cleaning around Pennington
Food Standards Agency data includes about 6 schools, colleges and universities, about 13 hospitals, care homes and childcare premises and about 4 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Pennington. Busy, occupied buildings like these are where clean supply air matters most. Pennington’s nearest hospital, Lymington New Forest Hospital, is about 1.4 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.
Wherever a school like Priestlands School has ducted ventilation, a half-term visit keeps the work out of lesson time. Healthcare ventilation, from large hospitals like Lymington New Forest Hospital (about 1.4 miles north) to small clinics, depends on clean filters, coils and ducts.

Your questions about AHU cleaning in Pennington
Do you cover smaller places like Pennington?
Yes, Pennington is part of our area, however small the site. The journey is planned ahead, so a few details about the route help.
Do you work at weekends in Pennington?
Yes, nights and weekends are routine for us. The work in Pennington can fit around your hours. Tell us your opening hours when you ask for a quote.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
What should I send you?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
Can you look after several sites?
Yes. Our area covers London and the South East, so sites at different addresses can be planned together as one programme. Every site has its own report.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
What does TR19 mean?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
How long does it take to clean an air handling unit?
As a guide, it takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, out of hours if needed.
