How the job changes from site to site

Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
AHU cleaning in Hale
Think of an AHU clean as a full check-up for the ventilation. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. If you are dealing with debris and leaves in the fresh air intake and rooms that smell stuffy when the system runs, we can help.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What affects the quote in Hale
A fixed price needs a few facts first. We check:
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- The times the site is available
- Parking and loading at the site
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any previous report or certificate
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- The postcode and the type of business
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.
Between visits
Here’s the after-treatment advice, in brief:
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Report stiff or damaged access doors
- Plan the next inspection before the last report gets filed away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the unit’s doors and panels in working order. Sections that are awkward to open are the ones that get skipped.
What a clean will not put right
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- Mechanical faults with motors, belts or bearings
- Damaged coils beyond cleaning
- Dirty ducts beyond the unit itself
If in doubt, give us a ring on 0345 646 2711, or email photos and we’ll say what we think before booking.
Parts of the system we cover
- Filter sections
- Dampers and louvres
- Internal panels
- Drain trays
- Supply and extract fans

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Hale, about 35 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. About 4.8 miles north-west of Hale is Fleet Community Hospital, the nearest hospital. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.

Why it’s worth doing now in Hale
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, so cleaning the ducts without the unit only goes so far. Equipment tucked in a roof space or outbuilding near Hale rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.
