In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
About our AHU cleaning in Norton
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. The work covers dampers and louvres, supply and extract fans and internal panels, and common reasons people get in touch are units needing a clean before a new tenant or handover and plant that has been serviced but not cleaned.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
A written report with photos follows every visit, 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.

FAQs for Norton
Will you come out to Norton?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
Can you come to Norton after we close?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Norton needn’t be disturbed. Your opening times are the first thing we ask for.
Is a quote from pictures possible?
Yes, if we can see what we need. If not, a site survey comes first, and the quote follows that.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What does AHU cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, typically ready within one working day.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What do you need from me for a quote?
A short description and a few photos plus the address and your hours. If we need more, we will ask.
When to call us in Norton
It matters for two reasons: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
It’s time to book a visit if you see:
- Filters that are clogged or overdue
- Units that have only ever had filter changes
- Stale or musty smells from the ventilation
- Units needing a clean before a new tenant or handover
Healthcare ventilation, from large hospitals like Fairfield Hospital (about 1.6 miles west) to small clinics, depends on clean filters, coils and ducts.

Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Report stiff or damaged access doors
- Keep filter changes on time and recorded
- Look at the condensate drain whenever the unit is serviced
- Don’t store bins or materials near the intake
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 make sure it stays clear.
Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
From a single site to a large estate, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with photos.
How it works
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. All told, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Norton, the date and timings are agreed with you well before the day.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Dig out any earlier paperwork for the system
- Make sure equipment near the work can be switched off and left to cool
- Tell us where we can park and unload

Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price so you know the cost before any work starts.

Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Our emergency line runs 24/7, but a planned visit to Norton is calmer for everyone.
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
