AHU cleaning in Butlocks Heath
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, once the unit has been shut down and isolated. The work covers filter sections, heating and cooling coils and dampers and louvres, and people most often call us about drain trays holding standing water and debris and leaves in the fresh air intake.
Work in a small place like Butlocks Heath starts with agreeing access and timings.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Stick to the filter change plan
- Diary the inspection date recommended in the report
- Make sure condensate is draining away
- Store the TR19 paperwork where auditors can find it
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 confirm water is draining away.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. In a small place like Butlocks Heath, the journey is planned ahead and the visit arranged around the site’s hours.
- The survey covers the unit, its access and how it can be shut down.
- 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.
Getting ready for the visit
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down

Advice
AHU cleaning around Butlocks Heath
Food Standards Agency data includes about 15 schools, colleges and universities and about 24 caring premises (care homes, nurseries and hospitals) within 1.5 miles or so of the middle of Butlocks Heath. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Butlocks Heath’s nearest hospital, Coldeast, is about 2.6 miles east. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
If you run an office near Netley station, its supply ductwork can gather dust for years before anyone looks inside. If you run a surgery, dental practice or care home near Butlocks Heath, clean ventilation matters as much to you as to a hospital like Coldeast (about 2.6 miles east).

Butlocks Heath questions

Yes, Butlocks Heath is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can you come to Butlocks Heath after we close?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Butlocks Heath needn’t be disturbed. Your opening times are the first thing we ask for.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. Before we leave, we tidy up and clean down.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
How long does it take to clean an air handling unit?
It takes half a day to a full day per unit, with large plant planned over several shifts. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line, and we’ll advise on what to do next.
Can you quote from photos?
Yes, for many jobs. Send wide shots, close-ups of any access panels and anything that worries you, and we usually come back within one working day. If photos are not enough, we will survey first.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
Different parts, different methods
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
Standing water in a tray sits right where the air passes. We clean it and note if the slope or the drain needs attention.
Managing agents and facilities teams in Butlocks Heath
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
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 can quote for the whole system.

When to call us in Butlocks Heath
Air handling units are typically tucked away on roofs, in plant rooms or above ceilings, so they’re easy to forget about. Months can pass without anyone looking inside.
Keep an eye out for these warning signs:
- Dirty coils holding back the airflow
- Fan sections that haven’t been cleaned in years
- Air handling units due a clean after building work
- Intake sections clogged with outdoor debris
Wherever a school like Netley Abbey Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.
