What affects the cost of AHU cleaning
A fixed price needs a few facts first. We check:
- Parking and loading at the site
- What state the system is in
- Working hours and out-of-hours timing
- A single visit or a regular plan
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.
What we need to know
When you call or email, it’s useful to have:
- Any previous report or certificate
- Any access panels or hatches you can see
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before any work starts.
How we handle AHU cleaning in New Marston
Drain trays under cooling coils are meant to empty. If the outlet blocks, standing water and slime build up, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you are dealing with air handling units never cleaned inside and air handling units due a clean after building work, we can help, from heating and cooling coils, internal panels and supply and extract fans onwards.
For a building near New Marston, the visit is planned around how it’s used, and the journey is planned ahead. The method does not change: inspect first, clean, then record what was done.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Why it’s worth doing now in New Marston
A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. A planned visit to New Marston fits your hours; an emergency does not.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, phone us on 0345 646 2711 or use the quote form and we will give you an honest view and a fixed quote.

How the job changes from site to site
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
Filters
Filters are the first line of defence in the unit. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Managing agents and facilities teams in New Marston
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. With shared responsibility, good records help everyone.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
What AHU cleaning cannot fix
A few issues sit outside what this work can do:
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
- Controls and BMS settings that run the unit
If in doubt, call us on 0345 646 2711 or send us an email and we’ll say what we think before you book.
Parts of the system we cover
- Dampers and louvres
- Drain trays

New Marston: your questions answered
Do you do school ventilation cleaning in New Marston in the summer holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 82 schools and colleges with food registrations within roughly a mile and a half of New Marston. Booking early in the term gives the best choice of holiday dates.
Can the work in New Marston be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
When should our AHU next be cleaned?
There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and we will suggest an interval after the first clean.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
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.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked and expects a risk-based approach.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
Is a quote from pictures possible?
Yes, for many jobs. Send a few wide pictures plus close-ups of panels, filters or grilles, and we typically come back within one working day. Some sites still need a visit, and we will say so.
Looking after it afterwards
Simple habits between visits make a real difference. We recommend:
- Make sure condensate is draining away
- Keep the certificate and photo report with the plant records
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
We recommend when the unit should next be inspected or cleaned, taking into account how dirty it was. TR19® Air is risk-based, so the interval depends on the unit and how the building is used.
Make the drain tray part of every maintenance visit. Catching a slow drain early stops standing water building up.
