AHU cleaning for kitchens and businesses in Hailey
The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. Common call-outs are for plant that has been serviced but not cleaned and dirty coils holding back the airflow, on drain trays, filter sections and dampers and louvres.
For a building in or near Hailey, access is agreed in advance and the visit is planned around the journey.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

Why act early in Hailey
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, especially where there’s been moisture. Somewhere as small as Hailey, losing a kitchen or building to a fault is felt by everyone who uses it.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

How we price AHU cleaning
Your quote is based on your site. We consider:
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
- Access, including roofs, risers and ceiling voids
- The scale of the work
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll explain what it covers.
What to send for a quote
There’s no need for technical detail. Just send:
- Wide photos of the system and the area around it
- The times we could work without disrupting the site
- Problems your staff have spotted
- The roof, plant room or outside wall the system runs to
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or email photos.
How it works
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. After that, the work takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Hailey.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Each section is cleaned of dust, debris and slime.
- We clean the coils and clear the tray and drain.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Mention any sign-in, permit or induction we need
- Mention any locked doors, roof access or ceiling voids
- Clear the space around the work
Ask for a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

When to call us in Hailey
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
Clients normally contact us after spotting something like this:
- Filters that are clogged or overdue
- Odours coming through the supply air
- Coils clogged with dust and debris
- Blocked condensate drains and slimy trays
Ventilation work in and around Hailey is risk-based: inspect, then clean what needs it.
What your quote should include
- Exactly which parts of the system are covered
- Whether the quote shows VAT
- If they look at the system before pricing
- What hours they’ll be on site
Hailey questions
Can ventilation in schools around Hailey be cleaned out of term?
Yes. The holidays are the usual time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hailey. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work at weekends in Hailey?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Hailey needn’t be disturbed. Let us know the hours you’re closed and we will book within them.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
Is there a survey before the work?
Yes. We always survey first, either from photos and details you send or on a site visit. Then you get a fixed quote.
Can you fix a faulty AHU?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
Do you work with multi-site operators?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Will the ventilation be off while you clean?
Yes, for the time we’re working on it. Out-of-hours work is available so the building is not left without ventilation when it’s busy.
What do you need from me for a quote?
Where the site is, what it is and when it’s open, along with a few pictures and any previous report.
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What a clean won’t put right
To be straight with you, some problems need a different fix:
- Breakdowns that need a mechanical engineer
- Ductwork downstream of the unit, which is a separate clean
- Leaking heating or cooling coils
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think before booking.
