What we’re called out for in Preston
An AHU’s intake draws in outdoor air and everything in it: dust, pollen, leaves and debris. The intake section and first filters take the brunt, and some travels further into the unit.
The symptoms we’re asked about most include:
- Rooms that smell stuffy when the system runs
- Condensate trays that won’t empty
- Dust built up on fan impellers
- Air handling units never cleaned inside
For workplaces around Preston Park station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What to look for in a quote
- Whether the work can be done while the site is closed
- What insurance they carry
- If they look at the system before pricing
- What paperwork you get at the end
AHU cleaning in Preston
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. If you have condensate trays that won’t empty and dirty fans and fan housings, we can help.
For a building near Preston, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

How the job changes from site to site
Heating and cooling coils
Cooling coils stay damp in use, so dirt on them can turn sticky. We clean the coil and the tray beneath it together.
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. We note any we find in the report.
What we do, step by step
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and the same goes into the written report. The visit takes one overnight shift for many single units, with bigger plant phased. Tell us about any gates, ladders or locked plant areas at your site near Preston when you book.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- A TR19® certificate and photo report follow the clean.
Before we arrive
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
How to get a quote
To help us quote: where the site is, what it is and its opening hours, a few pictures and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or email us.
Advice
Ventilation in Preston buildings
There are about 55 schools, colleges and universities, about 88 care, childcare and hospital premises and about 10 hotels and B&Bs on the FSA’s food hygiene register in and around Preston, up to about a mile and a half out. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Preston is about 45 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you. Montefiore Hospital is the nearest hospital, about 1 mile south of Preston. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
If you run a surgery, dental practice or care home near Preston, clean ventilation matters as much to you as to a hospital like Montefiore Hospital (about 1 mile south). Classrooms and halls at schools such as St Bernadette's Catholic Primary School are easiest to work in when pupils are away.

Postcode districts we cover here for AHU cleaning: BN1, BN3 and BN88. Whether your site is on Home Road, Bates Road and Loder Road or anywhere close by, we can help. With the A23 close by, Preston is simple for us to get to at any hour.

Near you in Preston
We work in commercial kitchens and buildings around Preston Park, The Crown and Anchor Inn and Varndean College and the streets around them. Preston has its own railway station: Preston Park station. Nearby you’ll also find Churchill Square (1.5 miles south) and Brighton Transport Museum (0.5 miles south). For a walk, there’s Newmarket Hill and Ladies Mile.
How we price AHU cleaning
We do not publish a price list, because sites vary so much. The quote depends on:
- Site requirements such as sign-in and permits
- A single visit or a regular plan
- The number of sites or systems
- The scale of the work
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.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
The quickest way to a quote is to send photos: 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.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Report water on the plant room floor
- Keep inspection doors on the unit in good order
- Report musty smells from the vents straight away
- Keep filter changes on time and recorded
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.

Preston: your questions answered
Do you do school ventilation cleaning in Preston in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 55 schools, colleges and universities with registered kitchens within about a mile and a half of Preston. Tell us your holiday dates and we will book the visit for when the site is empty.
Can the work in Preston be done at night or at weekends?
Yes, nights and weekends are routine for us. It means the site in Preston keeps running as normal. When you ring 0345 646 2711, or send details by email, mention when the site is quiet.
Do you have insurance?
Yes. We carry full insurance, and we’ve been trading since 2009.
What information do you need?
Only a few details: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then phone us on 0345 646 2711 or email us.
Which parts of an air handling unit do you clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.
How much notice do you need?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
Will you repair the fan or motor?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Is a quote from pictures possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Years of build-up make the job longer and harder, especially where there’s been moisture. In a smaller place like Preston, a site that has to close is felt quickly.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, call 0345 646 2711, or send details by email, and we’ll explain what it covers.
