Buckinghamshire · Air handling unit cleaning
Air handling unit cleaning in Granborough, Buckinghamshire
AHU cleaning for Granborough, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Leaves and litter drawn into the unit
- Dirty filters cutting the airflow
- Dust built up on fan impellers
Multi-site and managed buildings
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
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.
AHU cleaning in Granborough, done properly
An AHU clean is a thorough examination and treatment of the unit. We look inside each section, clean what we find and record it with pictures, so you can see the unit’s condition for yourself. Common call-outs are for dirty fans and fan housings and plant that needs cleaning after a refit, on filter sections, drain trays and supply and extract fans.
In a village or hamlet like Granborough, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.
Each 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.

How we price AHU cleaning
There’s no set price list, because no two systems are the same. What we look at:
- The scale of the work
- Whether several sites go on one quote
- What state the system is in
- How easy every part is to reach
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- Any previous report or certificate
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
For AHU cleaning in Granborough, call 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. We typically send a fixed quote within one working day.
What the work involves, part by part
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. Anything like that is recorded with photos.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
When it’s something else
We will not sell you work that does not address the problem, so here are the limits:
- The supply and extract ducts, quoted separately
- A system that is undersized for the building
- Damaged coils beyond cleaning
If you are not sure, just give us a ring on 0345 646 2711 or email us and we’ll give you a straight answer before you book.
What the work covers
- Internal panels
- Heating and cooling coils
- Supply and extract fans
- Dampers and louvres
- Drain trays
- Filter sections
Looking after it afterwards
Here’s the after-treatment advice, in brief:
- File each AHU report in the maintenance log
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
- Clear leaves and litter away from the intake
The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
Granborough: your questions answered
Do you work in villages like Granborough?
Yes, Granborough is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Do you work overnight in Granborough?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Your opening times are the first thing we ask for.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
How long does it take to clean an air handling unit?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Does the AHU have to be shut down for cleaning?
Yes. We can’t clean a running unit, so it’s switched off and made safe first. We agree the timing with your site team.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we will normally reply within one working day.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
Do you give a certificate after the clean?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
What we do, step by step
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. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Photos of the system and how to reach it help us plan a visit to Granborough.
- We survey the unit from photos or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Tell us where we can park and unload
- Let us know about permits to work or site inductions

Related advice
Leave it or put it right?
Facilities teams are often asked for evidence that the ventilation is looked after. A TR19® certificate and photo report give you that, for audits, tenants or your own peace of mind. It’s simpler to plan the work at Granborough now than to arrange it in a hurry later.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
