AHU Cleaning in Leagreen
We cover Leagreen for cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
AHU cleaning in Leagreen
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. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. If you have intake sections clogged with outdoor debris and condensate trays that won’t empty, we can put it right, from drain trays, internal panels and heating and cooling coils onwards.
Work in a small place like Leagreen starts with agreeing access and timings.
The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How it works
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. For a village or hamlet like Leagreen, tell us about narrow lanes, gates and parking when you book.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Tell us about site rules, permits or sign-in
Ask for a quote
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. That makes the next inspection of a building in Leagreen simpler. A planned visit to Leagreen is easier to arrange than an emergency callout.
What you pay depends on how big the system is, the condition it’s in and access to every part of it. We give you a fixed price before any work starts, so there are no surprises.

For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.

Ventilation in Leagreen buildings
Food Standards Agency records list about 4 caring premises (care homes, nurseries and hospitals) registered as food businesses in and around Leagreen, up to about a mile and a half out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Lymington New Forest Hospital is the nearest hospital, about 3.5 miles north-east of Leagreen. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Leagreen, clean ventilation matters as much to you as to a hospital like Lymington New Forest Hospital (about 3.5 miles north-east). Wherever a school like Hordle CofE (VA) Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Leagreen: your questions answered
Do you work overnight in Leagreen?
Yes, out-of-hours work is a big part of what we do. That way a site in Leagreen does not have to lose a day’s trading. Just call 0345 646 2711 or use the quote form with your opening times and we’ll plan around them.
Will you come out to Leagreen?
Yes, Leagreen is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Do you offer emergency callouts?
Yes. There’s a 24/7 emergency line for anything that can’t wait until a planned visit. Call us any time and explain what’s happened.

It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.

Yes. We’re fully insured, and we can share the details when you need them.
How do you protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
What do you do with what you remove?
We take it away when we go. While we work, it’s kept contained so the area stays clean.

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
How the job changes from site to site
Filters
Filters are the first line of defence in the unit. As part of the clean, filters are checked and cleaned or replaced as agreed, and the housing around them is cleaned too.
Drain trays
The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.
What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
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.
What affects the cost of AHU cleaning
A fixed price needs a few facts first. We look at:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- How big the system is
- Travel, parking and unloading
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 to send for a quote
To help us quote quickly, please include:
- The site address and the type of premises
- Wide photos of the system and the area around it
- Your last certificate, test record or report
- Detail shots of panels, filters and grilles
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
What a clean will not put right
Not every problem is solved by AHU cleaning, and we will tell you before work begins. It doesn’t solve:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
If you’re not sure, just call us on 0345 646 2711, or send details by email and we’ll give you a straight answer.
