About our AHU cleaning in Upper Enham
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, which is why we clean the unit itself, not just the ducts. We are often asked to deal with dust-coated heating and cooling coils and filters that are clogged or overdue, on internal panels, supply and extract fans and heating and cooling coils.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

AHU cleaning in Upper Enham: local notes
There are about 5 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central Upper Enham. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time.

Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you manage a school such as Smannell and Enham Church of England (Aided) Primary School, ventilation cleaning is best booked for the holidays.

Questions from Upper Enham
Do you work at weekends in Upper Enham?
Yes, we can come after you close and finish before you open. The work in Upper Enham can fit around your hours. When you give us a ring on 0345 646 2711, or email photos, mention when the site is quiet.
Do you work in villages like Upper Enham?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Are you accredited?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
How do you keep the site clean during the work?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How long does an AHU clean take?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Do you work with multi-site operators?
Yes. One number covers all your sites across London and the South East, and visits can be set on a regular cycle.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Why it’s worth doing now in Upper Enham
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 Upper Enham simpler. It’s worth booking a check, because nobody sees inside a duct day to day.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Watch for drips or damp patches near the plant
- Stick to the filter change plan
- Do not ignore odours coming through the grilles
- Make sure the unit’s access doors open easily
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Common problems we fix in Upper Enham
No filter stops everything. What gets through settles on coils, fans and the inside of the casing, a little more each month.
It’s time to book a visit if you see:
- Blocked condensate drains and slimy trays
- Dust built up on fan impellers
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
Healthcare buildings such as Andover War Memorial Hospital, about 2.6 miles south-west, depend on their ventilation; if you manage a surgery, clinic or care home near Upper Enham, yours matters too.
