AHU Cleaning in West Grinstead
Professional AHU cleaning in and around West Grinstead, timed so the site keeps working and finished with a written report and pictures.
- Air handling units with blocked filters
- Dirty coils holding back the airflow
- Plant that needs cleaning after a refit
What your team can do, and what needs us
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
How we handle AHU cleaning in West Grinstead
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so you can see the unit’s condition for yourself. The work covers dampers and louvres, drain trays and filter sections, and people most often call us about blocked condensate drains and slimy trays and rooms that smell stuffy when the system runs.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like West Grinstead are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters, coils, fan section and casing are cleaned in turn.
- Drain trays are cleared and cleaned and the outlet checked.
- You get a TR19® certificate and a photo report.
Preparing for the visit
- Have your last certificate or report to hand
- Tell us where we can park and unload
- Tell us the best time to work, such as after service or at a weekend

The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
When something else is needed
It’s worth knowing the limits before booking:
- Mechanical faults with motors, belts or bearings
- A system that is undersized for the building
- The supply and extract ducts, quoted separately
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Filter sections
- Internal panels
- Dampers and louvres
- Drain trays
- Supply and extract fans
- Heating and cooling coils
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Change filters on schedule and log each change
- Make sure the unit’s access doors open easily
- Report water on the plant room floor
- Book the next check in line with the report
If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can quote for both.
Check drain trays and condensate drains during routine maintenance. Catching a slow drain early stops standing water building up.
Why it’s worth doing now in West Grinstead
A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Dealing with it early keeps the clean straightforward. A fault that closes a site in a village like West Grinstead affects everyone who depends on it.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we’ll price it together.

How much does AHU cleaning cost in West Grinstead?
It depends on the site, so we quote each one individually. For a quote, ring 0345 646 2711 or email us and tell us about the site and its opening hours.
What do you need from me for a quote?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
How long does an AHU clean take?
Cleaning takes a single shift for a typical unit, longer for large or heavily soiled ones. Bigger units can be phased, so give us a ring on 0345 646 2711, or send details by email to talk it through.
How often should an air handling unit be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Where does the waste go?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
For landlords and multi-site operators
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Facilities teams in offices, schools and healthcare sites book us too across West Sussex. Work can be phased by floor, building or site around the people who use them.
How we price AHU cleaning
There’s no set price list, because sites vary so much. What we look at:
- How easy every part is to reach
- Whether several sites go on one quote
- When the work can happen, such as evenings, overnight or weekends
- The condition of the system
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.
Helping us quote
Many jobs can be priced from pictures and some basics. Send what you can of the following:
- The times we could work without disrupting the site
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
We don’t publish a price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To start, ring 0345 646 2711 or use the quote form.
