About our AHU cleaning in Sarisbury
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with rooms that smell stuffy when the system runs and dirty fans and fan housings, across supply and extract fans, drain trays and heating and cooling coils.
Smaller buildings around Sarisbury often keep their ventilation units in a roof void or plant cupboard, where they’re easy to forget. Filters, coils and drain trays need attention whatever the size of the unit.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Different parts, different methods
Heating and cooling coils
Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.
Filters
Filter condition tells you a lot about the rest of the unit. They’re photographed before and after for your records.

Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Diary the inspection date recommended in the report
- Report water on the plant room floor
- Make sure the unit’s access doors open easily
- Make sure condensate is draining away
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
What affects the cost of AHU cleaning
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether we need access equipment or extra panels
- How big the system is
- Working hours and out-of-hours timing
- What state the system is in
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered and we will price it together.

- Photos showing the whole system and its surroundings

When to call us in Sarisbury
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
What we are most often called out for:
- Dirty coils holding back the airflow
- Units needing a clean before a new tenant or handover
- Plant that has been serviced but not cleaned
- Filters that are clogged or overdue
Coldeast, about under half a mile south, is the nearest hospital to Sarisbury, and healthcare sites of every size need their supply air kept clean.

Why act early in Sarisbury
Leave an AHU uncleaned and the dirt doesn’t stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Around Sarisbury, a kitchen or building out of action is missed straight away.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

What your team can do, and what needs 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.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We will take a look and send you a fixed quote.
The process
Every visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Because the survey comes first, a visit to Sarisbury can usually be finished without a second trip.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Tell us where we can park and unload
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Advice
Sarisbury questions
Can a school’s ventilation in Sarisbury be done out of term time?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 11 schools, colleges and universities with registered kitchens within about a mile and a half of Sarisbury. Booking early in the term gives the best choice of holiday dates.
Do you work in villages like Sarisbury?
Yes. Sarisbury is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
Can you fix a faulty AHU?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
What do you clean inside the unit?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
What does TR19 mean?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we’ll usually reply within one working day.
Can we book visits on a schedule?
Yes. Scheduled maintenance plans are part of what we do, with visits at the interval your system needs. Each report recommends when the next visit should be.
