What affects the quote in Sutton
The survey tells us what the work involves. We look at:
- Any permits to work or inductions
- How big the system is
- Travel, parking and unloading
- Whether several sites go on one quote
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll go through it with you.
Helping us quote
You do not need the technical terms. Just send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Wide pictures of the system and the area around it
- How we’d reach plant on a roof or in a plant room
- When the site is open and when it’s quiet
If you need AHU cleaning in Sutton, phone us on 0345 646 2711, or send details by email. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We typically send a fixed quote within one working day.
How we handle AHU cleaning in Sutton
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with rooms that smell stuffy when the system runs and dust-coated heating and cooling coils, we can help.
Somewhere as small as Sutton, ducted ventilation is normally limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Multi-site and managed buildings
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Between visits
Think of this as the after-treatment advice, short and simple:
- Report stiff or damaged access doors
- Check the drain tray is emptying during routine visits
- Note any water around the unit or leaks below it
- Flag stale or damp smells in the supply air
The report shows each section of the unit before and after, and note any part we couldn’t get to. Any defects we noticed, like a leaking tray or damaged lining, are listed.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What your team can do, and what needs us
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.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what AHU cleaning will not do:
- Leaking heating or cooling coils
- Ductwork downstream of the unit, which is a separate clean
- A system that is undersized for the building
If you’re not sure, just ring 0345 646 2711, or send details by email and we will give you a straight answer.
What we work on in Sutton
- Internal panels
- Filter sections
- Heating and cooling coils
- Dampers and louvres
- Supply and extract fans
- Drain trays
How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to Sutton run smoothly.
- First we agree when the unit can be switched off, including evenings or weekends.
- 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.
- After pictures are taken and the certificate issued.
Getting ready for the visit
- Clear loose items from the work area
- Let us know about permits to work or site inductions
- Allow time for equipment near the work to be turned off and cool down

Questions from Sutton
Do you work overnight in Sutton?
Yes, out-of-hours work is a big part of what we do. It means the site in Sutton keeps running as normal. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Do you cover smaller places like Sutton?
Yes, Sutton is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
How long does an AHU clean take?
Typically the clean takes a single shift for a typical unit, longer for large or heavily soiled ones. The shutdown is planned to fit, including evenings or weekends.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Inspection tells you when cleaning is needed, and the report recommends a next date.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
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.
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. We confirm the scope after looking at the unit.

Why deal with it now?
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. Somewhere as small as Sutton, losing a kitchen or building to a fault is felt by everyone who uses it.
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.
