Hampshire · Air handling unit cleaning
Air handling unit cleaning in Holt End, Hampshire
AHU cleaning for Holt End, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Coils clogged with dust and debris
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Store the TR19 paperwork where auditors can find it
- Stick to the filter change plan
- Book the next check in line with the report
- Make sure condensate is draining away
The report suggests a date for the next inspection or clean, based on what we found. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
AHU cleaning for kitchens and businesses in Holt End
Where a building in Holt End has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. Common call-outs are for dust-coated heating and cooling coils and drain trays holding standing water, across heating and cooling coils, drain trays and filter sections.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
Every visit ends with a written report and photos, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Why deal with it now?
A clean unit feeds cleaner air into the ductwork, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. In a place like Holt End, ductwork and fans are easy to forget until something goes wrong.
Working hours, access and the scale of the site can all change the price. We take each of them into account, and the price is fixed before work begins.

How it works
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. If you can send photos, we can arrive in Holt End knowing what to expect.
- First the unit is surveyed, from pictures or a visit, and the scope agreed.
- 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.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Move anything stored near the system
- Mention any parking or loading restrictions
How to get a quote

How much does AHU cleaning cost in Holt End?
It depends on the site, so we quote each one individually. To get one, ring 0345 646 2711, or send details by email with the site type, opening hours and a few photos.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you do ventilation duct cleaning too?
Yes, the ductwork, grilles and diffusers the unit serves. We’ll tell you after the survey whether the ducts need it.
Will the ventilation be off while you clean?
Yes. The unit has to be shut down and isolated before it’s opened. The shutdown is planned with whoever runs the building.
How often should an air handling unit be cleaned?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- How big the system is
- Whether several sites go on one quote
- Site rules, permits and inductions
- The times the site is available
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.
Asking for a quote
A few details help us quote accurately. With your enquiry, please include:
- The site address and the type of premises
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Then phone us on 0345 646 2711 or use the quote form.
Staff cleaning versus specialist work
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.

Different parts, different methods
Filters
Dirty filters cut airflow and let dirt slip past their frames. The filter section is cleaned so new or cleaned filters sit properly.
Heating and cooling coils
Because cooling coils run wet, the dirt on them tends to cling. We clean the coil and the tray beneath it together.

When to call us in Holt End
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.
Common reasons sites call us include:
- Plant that needs cleaning after a refit
- Condensate trays that won’t empty
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
Classrooms and halls at schools such as St Mary's Bentworth Church of England Primary School are easiest to work in when pupils are away.
