AHU cleaning in New Milton
If the units serving a building in New Milton have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full AHU clean takes in the whole unit. If you’re dealing with air handling units never cleaned inside and drain trays holding standing water, we can help.
For a building near New Milton, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What your team can do, and what needs us
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.

What the work involves, part by part
Drain trays
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
What affects the cost of AHU cleaning
The price is fixed before any work begins. It’s based on:
- One-off work versus a regular cycle
- Parking and loading at the site
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The postcode and the type of business
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- Any access panels or hatches you can see
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, call 0345 646 2711 or send us an email.
When it’s something else
In fairness, there are a few things this work won’t fix:
- Problems with the unit’s controls or sensors
- Leaking heating or cooling coils
- Mechanical faults with motors, belts or bearings
If in doubt, phone us on 0345 646 2711 or drop us a line and we’ll say what we think before you book.

Common questions in New Milton
Can you clean school ventilation in New Milton during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 9 schools, colleges and universities with registered kitchens within about a mile and a half of New Milton. You can call us on 0345 646 2711 or send us an email with the dates the site is empty.
Do you work in villages like New Milton?
Yes, New Milton is part of our area, however small the site. A survey first, from photos or a visit, means we arrive with the right kit.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What’s included in an AHU clean?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. What happens to the filters is agreed when we quote.
How do you keep the site clean during the work?
Floors and surfaces near the work are sheeted before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
How long will the unit be out of action?
The work takes half a day to a full day per unit, with large plant planned over several shifts. Large plant can be split over several shifts, and you can phone us on 0345 646 2711 or use the quote form to plan it.
Can you quote from pictures?
Normally, yes. Send wide shots, close-ups of any access panels and anything that worries you, and a fixed quote usually follows within one working day. Some sites still need a visit, and we will say so.
Can one contract cover all our sites?
Yes. We work across South East England and London, so we can schedule a run of sites on one programme. Every site has its own report.
What happens on the day
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes one overnight shift for many single units, with bigger plant phased, and we clear up before we go. Visits to a place like New Milton are planned ahead, so we arrive with what the survey says the job needs.
- We agree a shutdown window that suits the building.
- 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 pictures and issue the certificate and report.
Getting ready for the visit
- Move anything stored near the system
- Let us know about parking and loading
- Agree a time when the area can be out of use
Get a fixed quote
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
Aftercare tips
Here’s the after-treatment advice, in brief:
- Note any water around the unit or leaks below it
- Report musty smells from the vents straight away
- Plan the next inspection before the last report gets filed away
- Keep the certificate and photo report with the plant records
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to make sure it stays clear.
Change or clean filters on time. Once filters clog, dirt starts getting past them.
Common problems we fix in New Milton
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Keep an eye out for any of the following:
- Dirty coils holding back the airflow
- Units that have only ever had filter changes
- Blocked condensate drains and slimy trays
- Air handling units due a clean after building work
If you run a surgery, dental practice or care home near New Milton, clean ventilation matters as much to you as to a hospital like Lymington New Forest Hospital (about 5.1 miles east).
What your quote should include
- Whether a survey comes first
- Whether the price is fixed
- Whether the work can be done while the site is closed
- Proof of accreditation you can verify
