How we handle AHU cleaning in Crowmarsh Gifford
Our AHU cleans for sites in Crowmarsh Gifford cover the parts that collect dirt: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. If you are dealing with plant that has been serviced but not cleaned and dirty filters cutting the airflow, we can put it right, from dampers and louvres, filter sections and heating and cooling coils onwards.
Work in a small place like Crowmarsh Gifford starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work aren’t the same thing. 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.
Keeping the system healthy
Results last longer with the right care. We suggest:
- Report water on the plant room floor
- Report stiff or damaged access doors
- Keep the area around the fresh air intake clear
- Look at the condensate drain whenever the unit is serviced
If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
How we price AHU cleaning
The survey tells us what the work involves. We look at:
- The scale of the work
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
Helping us quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Any access panels or hatches you can see
- Wide pictures of the system and the area around it
- Problems your staff have spotted
- Any previous report or certificate
To get a fixed quote, ring 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few photos and your last certificate or report help a lot. You will normally have a quote within one working day.
Crowmarsh Gifford questions
Do you cover smaller places like Crowmarsh Gifford?
Yes, we work in villages as well as towns, and Crowmarsh Gifford is covered. Photos of the system and directions to the site help us plan the visit.
Can you clean school ventilation in Crowmarsh Gifford during the holidays?
Yes, out-of-term visits are normal for schools. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Crowmarsh Gifford, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
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.
Is there a survey before the work?
Yes. Photos often do the job, and larger or hidden systems get a visit.
Does the AHU have to be shut down for cleaning?
Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.
How much does AHU cleaning cost in Crowmarsh Gifford?
Size, condition, access and working hours all affect the cost. Ask us for a fixed quote and we will typically reply within one working day.
Can you clean the AHU out of hours?
Yes. Evening, overnight and weekend work is all possible, so the building keeps running in the day.
Can you come out in an emergency?
Yes, day and night, every day of the year. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Part by part
Heating and cooling coils
A dirty coil holds back the air and makes heating and cooling less effective. A clean gets air moving through the coil properly again.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with pictures.
How the visit works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. From there, it takes anything from half a day for one small unit to several shifts for a plant room full of them. Rural roads and tight entrances are worth telling us about before a visit to Crowmarsh Gifford.
- The survey covers the unit, its access and how it can be shut down.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Preparing for the visit
- Clear the space around the work
- Tell us the best time to work, such as after service or at a weekend
- Plan for cooking equipment or plant to be off before we arrive
How to get a quote
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.

When it’s something else
Not every problem is solved by AHU cleaning, and we will tell you before any work starts. It will not put right:
- Breakdowns that need a mechanical engineer
- Ventilation that was badly designed in the first place
- Dirty ducts beyond the unit itself
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we will tell you honestly.
Where we work
- Dampers and louvres
- Internal panels
- Supply and extract fans
- Drain trays
- Heating and cooling coils
- Filter sections
When to call us in Crowmarsh Gifford
Cooling coils create condensation, and that water has to go somewhere. A blocked outlet or a badly sloped tray leaves standing water, and that is where slime and odours start.
Common reasons sites call us are:
- Debris and leaves in the fresh air intake
- Dirty filters cutting the airflow
- Dirty fans and fan housings
- Dust-coated heating and cooling coils
Ventilation work in and around Crowmarsh Gifford is risk-based: inspect, then clean what needs it.
