AHU cleaning for kitchens and businesses in Old Alresford
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for blocked condensate drains and slimy trays and dirty filters cutting the airflow, across internal panels, drain trays and filter sections.
For a building in or near Old Alresford, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

What we’re called out for in Old Alresford
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Clients usually contact us after spotting one of these:
- Dirty coils holding back the airflow
- Intake sections clogged with outdoor debris
- Air handling units never cleaned inside
- Rooms that smell stuffy when the system runs
Classrooms and halls at schools such as Perins School are easiest to work in when pupils are away.
What to look for in a quote
- Whether a survey comes first
- What paperwork you get at the end
- Proof of insurance
- Whether inaccessible sections are listed on the report

What AHU cleaning cannot fix
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
- Controls and BMS settings that run the unit
If you’re not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.
Parts of the system we cover
- Supply and extract fans
- Dampers and louvres
- Internal panels
- Drain trays

- Heating and cooling coils
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes anything from half a day for one small unit to several shifts for a plant room full of them, and the area is cleaned down before we leave. If you can send photos, we can arrive in Old Alresford knowing what to expect.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- After photos are taken and the certificate issued.
How to prepare
- Tell us where we can park and unload
- Plan for cooking equipment or plant to be off before we arrive
- Dig out any earlier paperwork for the system

Your questions about AHU cleaning in Old Alresford
Can you get to a site in Old Alresford?
Yes, we work in villages as well as towns, and Old Alresford is covered. The journey is planned ahead, so a few details about the route help.
Can you do AHU cleaning in Old Alresford?
Yes. Our area runs across London and the South East, Old Alresford included. A fixed quote typically follows within one working day of the survey details.
How long does it take to clean an air handling unit?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. We plan the shutdown around that, out of hours if needed.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. We do not leave it behind.
Can you clean the ducts connected to the AHU?
Yes. Ductwork is cleaned through access panels, with anything inaccessible recorded, with new panels fitted where needed.
Do you offer emergency callouts?
Yes, any time. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.

Fixed quotes for AHU cleaning in Old Alresford
We quote each job individually. These are the things that affect it:
- How many systems or sites are involved
- The times the site is available
- Whether it’s a one-off visit or part of a schedule
- Site requirements such as sign-in and permits
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, ring 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- The site address and the type of premises
- How we’d reach plant on a roof or in a plant room
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711 or drop us a line.
Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, so you can show an insurer or inspector what was done at each site.
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side and send the paperwork to whoever needs it.
Why deal with it now?
Facilities teams are often asked for evidence that the ventilation is looked after. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Systems in rural buildings are often out of sight and out of mind.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
