About our AHU cleaning in Turnford
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with blocked condensate drains and slimy trays and stale or musty smells from the ventilation, we can help, from supply and extract fans, internal panels and filter sections onwards.
Around a place like Turnford, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.
We have been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Why act early in Turnford
When the unit is clean, less dirt reaches the ducts, so the whole system stays cleaner for longer. It also means the next inspection has less to find. Around Turnford, a kitchen or building out of action is missed right away.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.

Signs you need AHU cleaning in Turnford
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For anyone working, learning or staying in a building in Turnford, that’s air they breathe for hours at a time.
Any of these means the system needs a check-up:
- Dirty filters cutting the airflow
- Odours coming through the supply air
- Units that have only ever had filter changes
- Intake sections clogged with outdoor debris
Wherever a school like Longlands Primary School and Nursery has ducted ventilation, a half-term visit keeps the work out of lesson time.

AHU cleaning in Turnford: local notes
There are about 11 schools, colleges and universities and about 15 care, childcare and hospital premises on the FSA’s food hygiene register within about 1.5 miles of central Turnford. Busy, occupied buildings like these are where clean supply air matters most. Turnford, about 16 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. About 4.8 miles south-west of Turnford is St Michaels Hospital, the nearest hospital. Clean air matters most where people are unwell, and that’s as true in a care home as in a hospital.
Hospitals such as St Michaels Hospital (about 4.8 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Turnford are no different.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. 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 need training, the right equipment and safe access. That is our job.
What the work involves, part by part
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Problems with the unit’s controls or sensors
- Mechanical faults with motors, belts or bearings
- Ductwork downstream of the unit, which is a separate clean
Not sure which it is? You can ring 0345 646 2711 or drop us a line and we will tell you honestly.

How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before any work starts, and the area around the work is covered and protected. On site, it takes one overnight shift for many single units, with bigger plant phased. We plan the journey to Turnford and bring what the job is likely to need.
- We survey the unit from pictures or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool

What affects the cost of AHU cleaning
We quote each job individually. This is what makes a difference:
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- A single visit or a regular plan
- How easy every part is to reach
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Any symptoms, from odd noises to smells or leaks
- How we’d reach plant on a roof or in a plant room
- Wide pictures of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
