About our AHU cleaning in Pitch Green
Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. Common call-outs are for units that have only ever had filter changes and condensate trays that won’t empty, on drain trays, filter sections and internal panels.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Keeping the system healthy
To keep the system working properly between visits:
- Change filters on schedule and log each change
- Report water on the plant room floor
- Make sure condensate is draining away
- Plan the next inspection before the last report gets filed away
Restart the unit with your site team or maintenance contractor once we’ve finished. Keep an eye on the condensate drain over the next few days to confirm water is draining away.
Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.
What AHU cleaning can’t fix
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Ductwork downstream of the unit, which is a separate clean
- Ventilation that was badly designed in the first place
- Building management system faults
Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we will tell you honestly.

What else we do in Pitch Green
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- What state the system is in
- Working hours and out-of-hours timing
- The size of the system
- Whether it’s a one-off visit or part of a schedule
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before we start.
Helping us quote
When you call or email, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
FAQs for Pitch Green
Do you cover smaller places like Pitch Green?
Yes, we work in villages as well as towns, and Pitch Green is covered. Let us know about access, parking and anything unusual about getting there when you book.
Is Pitch Green in your area for AHU cleaning?
Yes, Pitch Green is covered. A fixed quote normally follows within one working day of the survey details.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
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.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so offices, schools and shops can carry on.
Do you have insurance?
Yes. We’re fully insured, and the details are available on request.
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.
What should I send you?
Some pictures and a quick description of the system, with the address and opening hours. We will ask for anything else we need.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. We clean the intake and first stage of filters along with the rest.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
The process
Each visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the AHU cleaning, tidy up and hand over the paperwork. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. Rural roads and tight entrances are worth telling us about before a visit to Pitch Green.
- First the unit is surveyed, from photos or a visit, and the scope agreed.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Let us know about parking and loading
- Agree a time when the area can be out of use
- Arrange a key holder or contact on site
