Your questions about AHU cleaning in Barnsole
Can you come to Barnsole after we close?
Yes, nights and weekends are routine for us. It means the site in Barnsole keeps running as normal. When you phone us on 0345 646 2711 or use the quote form, mention when the site is quiet.
Will you come out to Barnsole?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
What do you do to protect the area?
Floors and surfaces near the work are sheeted before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that cannot wait. Ring any time and tell us what’s happened.
Do you clean the ductwork as well?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
How we handle AHU cleaning in Barnsole
An air handling unit is the heart of a building’s ventilation: it draws air in, filters it, heats or cools it and pushes it round the ductwork. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers heating and cooling coils, filter sections and drain trays, and the jobs we see most are debris and leaves in the fresh air intake and condensate trays that won’t empty.
For a building in or near Barnsole, access is agreed in advance and the visit is planned around the journey.
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.

Keeping the system healthy
Think of this as the after-treatment advice, in brief:
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the area around the intake clear. Anything around the intake is likely to be drawn in.
Leave it or put it right?
Stuffy rooms and stale smells in a building in Barnsole can sometimes be traced back to the AHU. Cleaning it deals with the cause rather than the symptom. A planned visit to Barnsole is easier to arrange than an emergency callout.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before we start.

Landlords, agents and facilities managers
Multi-site operators often want one contractor and one number. We work across London and the South East, so a run of sites can go into one programme and kept to a regular schedule.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We’re happy to deal with either side, and the report can go to both.
Part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Drain trays
Older trays can corrode and start leaking. Their condition goes into the report with pictures so you can decide on any repairs.
How it works
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Seeing the system in pictures first means the trip to Barnsole can be planned properly.
- We survey the unit from pictures or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
How to prepare
- Name a contact who can let us in at the agreed time
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
The quickest way to a quote is to send pictures: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.

When something else is needed
AHU cleaning can’t fix everything, and we will tell you before any work starts. It won’t put right:
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711 or use the quote form and we will tell you honestly.

What affects the quote in Barnsole
The survey tells us what the work involves. The main factors are:
- Whether we need access equipment or extra panels
- Travel, parking and unloading
- The size of the system
- Site requirements such as sign-in and permits
No two sites are the same, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
