Surrey · Air handling unit cleaning
Air handling unit cleaning in Horne, Surrey
One call covers cleaning of air handling units, including filters, coils, drain trays, fans and internal surfaces in Horne, from survey to sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.

How the job changes from site to site
Fans and fan sections
Build-up on fan blades can upset the balance and add wear. Cleaning keeps it running as intended.
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. Cleaning restores the open path through the fins.
How we handle AHU cleaning in Horne
Our AHU cleans for sites in Horne cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. Every clean comes with a TR19® certificate and before and after pictures in a report. If you have leaves and litter drawn into the unit and air handling units never cleaned inside, we can help, from dampers and louvres, filter sections and internal panels onwards.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Honest limits
We will not sell you work that doesn’t address the problem, so here are the limits:
- Dirty ducts beyond the unit itself
- Building management system faults
- Ventilation that was badly designed in the first place

What the work covers
- Internal panels
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Heating and cooling coils
- Filter sections
What your team can do, and what needs us
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Do you need AHU cleaning in Horne?
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. Most of it lands at the intake and the first stage of filters, and some travels further into the unit.
Clients normally contact us when they notice one of these:
- Coils clogged with dust and debris
- Dirty filters cutting the airflow
- Condensate trays that won’t empty
- Units that have only ever had filter changes
Healthcare buildings such as East Surrey Hospital, about 4.2 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Horne, yours matters too.

Your questions about AHU cleaning in Horne
Can you work in Horne outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Horne can fit around your hours. Your opening times are the first thing we ask for.
Do you work in villages like Horne?
Yes. Villages and rural sites across the South East are part of our work, Horne included. Photos of the system and directions to the site help us plan the visit.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Are you insured?
Yes, we are fully insured. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Are you accredited?
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.
What do you clean inside the unit?
Every section that collects dirt: filters, coils, tray, fan and panels. We confirm the scope after looking at the unit.
What about areas you cannot get to?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, with any faults we noticed.
What happens if it’s left?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. Out of sight is the usual reason a rural system goes too long without attention.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will go through it with you.

What affects the cost of AHU cleaning
Before we fix a price, we need to know a few things. We look at:
- Access, including roofs, risers and ceiling voids
- Site requirements such as sign-in and permits
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
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 play a part.
Asking for a quote
Many jobs can be priced from photos and some basics. Send what you can of the following:
- How we’d reach plant on a roof or in a plant room
- Where the site is and what kind of site it is
- Any access panels or hatches you can see
- Your opening hours and when the area is out of use
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
How it works
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Horne run smoothly.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Mention any parking or loading restrictions
- Clear loose items from the work area
