About our AHU cleaning in Newhall
If the units serving a building in Newhall have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you are dealing with air handling units due a clean after building work and condensate trays that won’t empty, we can put it right, from filter sections, supply and extract fans and internal panels onwards.
Around a place like Newhall, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Flag stale or damp smells in the supply air
- Look at the condensate drain whenever the unit is serviced
- Keep the area around the fresh air intake clear
- Store the TR19 paperwork where auditors can find it
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
What affects the quote in Newhall
The survey tells us what the work involves. We look at:
- Parking and loading at the site
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- Site rules, permits and inductions
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Problems your staff have spotted
- Wide pictures of the system and the area around it
- The paperwork from the last visit, if you have it
- How we’d reach plant on a roof or in a plant room
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Why act early in Newhall

Common questions in Newhall
Do you do school ventilation cleaning in Newhall in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of Newhall, it pays to plan holiday dates ahead. Send us your term dates when you give us a ring on 0345 646 2711, or email photos, and we will fit the work in.
Can you get to a site in Newhall?
Yes, we work in villages as well as towns, and Newhall is covered. The journey is planned ahead, so a few details about the route help.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.
How long does it take to clean an air handling unit?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. The shutdown is planned to fit, out of hours if needed.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
How much does AHU cleaning cost?
It depends on the site, so we quote each one individually. To get one, call us on 0345 646 2711, or email photos with the site type, opening hours and a few pictures.
Do you work evenings or weekends?
Yes. We time the work to fit the building’s hours. In hospitals and care homes, we agree timings with the site team.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool before work begins, and floors and nearby surfaces are sheeted. On site, it takes from a few hours for a compact unit to a day or more for a large one. Visits to a place like Newhall are planned ahead, so we arrive with what the survey says the job needs.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Let us know when the site is closed or quiet
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
Getting a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before we start.

Do you need AHU cleaning in Newhall?
It matters for two reasons: the unit supplies the air people breathe, and a dirty unit has to work harder. For the people using the building every day, that is the air they breathe for hours on end.
Clients normally contact us when they notice something like this:
- Dust-coated heating and cooling coils
- Leaves and litter drawn into the unit
- Units that have only ever had filter changes
- Units needing a clean before a new tenant or handover
Healthcare ventilation, from large hospitals like Princess Alexandra Hospital (about 2.1 miles west) to small clinics, depends on clean filters, coils and ducts.
What to look for in a quote
- Proof of insurance
- Whether the work can be done while the site is closed
- Whether VAT is included
- How areas they cannot reach will be recorded
Honest limits
AHU cleaning cannot fix everything, and we’ll tell you before any work starts. It won’t put right:
- Coils that are corroded or leaking and need replacing
- Ventilation that was badly designed in the first place
- Ductwork downstream of the unit, which is a separate clean
If you’re not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer before booking.
