How we handle AHU cleaning in Birch Green
Where a building in Birch Green has had little more than filter changes, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. The work covers internal panels, heating and cooling coils and filter sections, and the jobs we see most are stale or musty smells from the ventilation and units that have only ever had filter changes.
In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Questions from Birch Green
Is AHU cleaning available in Birch Green?
Yes, we work in Birch Green and the places around it. A fixed quote normally follows within one working day of the survey details.
Do you work at weekends in Birch Green?
Yes. We work evenings, overnight and at weekends. The work in Birch Green can fit around your hours. Your opening times are the first thing we ask for.
What do you clean inside the unit?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Which accreditations do you hold?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
What if parts of the system can’t be reached?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.
Will you repair the fan or motor?
AHU cleaning is what we offer here, not mechanical repairs. If we spot a fault, we note it in the report so your maintenance contractor can deal with it.

How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Somewhere like Birch Green, lanes, gates and parking are worth mentioning in advance.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
Preparing for the visit
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Let us know when the site is closed or quiet
Ask for a quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.
Related advice
Why act early in Birch Green
If people in a building in Birch Green complain about stuffy or smelly air, the AHU is worth looking at. Cleaning it deals with the cause rather than the symptom. In a place like Birch Green, ductwork and fans are easy to forget until something goes wrong.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before we start.

What staff can safely do
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That’s our job.
Honest limits
Not every problem is solved by AHU cleaning, and we’ll tell you before work begins. It does not solve:
- Damaged coils beyond cleaning
- Building management system faults
- Ventilation that was badly designed in the first place
If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think.
What the work covers
- Filter sections
- Supply and extract fans
- Drain trays
- Dampers and louvres
- Internal panels
- Heating and cooling coils
Aftercare tips
To keep the system working properly between visits:
- Stick to the filter change plan
- File each AHU report in the maintenance log
- Diary the inspection date recommended in the report
- Make sure the unit’s access doors open easily
The report suggests a date for the next inspection or clean, based on what we found. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Travel, parking and unloading
- One-off work versus a regular cycle
- Whether we need access equipment or extra panels
- What state the system is in
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, give us a ring on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
Helping us quote
Photos let us diagnose from a distance. Try to include:
- Any access panels or hatches you can see
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your opening hours and when the area is out of use
- Any symptoms, from odd noises to smells or leaks
Every quote begins with a look at the system, from your pictures and details or, where that is not enough, a survey on site. Then we send a fixed price so you know the cost before we start.
