Well: your questions answered
Can you work in Well outside opening hours?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Well needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Will you come out to Well?
Yes. Villages and rural sites across the South East are part of our work, Well included. Let us know about access, parking and anything unusual about getting there when you book.
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’ll suggest an interval after the first clean.
How long does it take to clean an air handling unit?
Cleaning takes from a few hours for a compact unit to a day or more for a large one. Bigger units can be phased, and you can call 0345 646 2711 or use the quote form to plan it.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’ve been trading since 2009 and we’re fully insured.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
Can you fix a faulty AHU?
We clean the unit and flag faults rather than repair them, with the details in the report.
AHU cleaning in Well, done properly
Our AHU cleans for sites in Well cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. Typical jobs include intake sections clogged with outdoor debris and air handling units never cleaned inside, across heating and cooling coils, drain trays and dampers and louvres.
For a building in or near Well, access is agreed in advance and the visit is planned around the journey.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

Part by part
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. We clean them with care so the fins are not damaged.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
What affects the quote in Well
There’s no set price list, because no two systems are the same. What we look at:
- How big the system is
- How many systems or sites are involved
- When the work can happen, such as evenings, overnight or weekends
- Travel, parking and unloading
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before we start.
What to send for a quote
To help us quote quickly, please include:
- The site address and the type of premises
- The paperwork from the last visit, if you have it
- Wide photos of the system and the area around it
- When the site is open and when it’s quiet
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before work begins.
What AHU cleaning cannot fix
AHU cleaning cannot fix everything, and we will tell you before we start. It does not solve:
- The supply and extract ducts, quoted separately
- Mechanical faults with motors, belts or bearings
- Building management system faults
If in doubt, call 0345 646 2711 or use the quote form and we’ll say what we think.
What the work covers
- Heating and cooling coils
- Drain trays
- Internal panels
- Filter sections
- Supply and extract fans
- Dampers and louvres
What else we do in Well
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
When to call us in Well
An overdue filter loads up with dirt, which cuts the airflow and can let air slip round the filter. Then the rest of the unit takes the load.
Signs it’s time to call us include:
- Units that have only ever had filter changes
- Fan sections that haven’t been cleaned in years
- Rooms that smell stuffy when the system runs
- Air handling units with blocked filters
Hospitals such as Fleet Community Hospital (about 5.8 miles north-east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Well are no different.
Before you book anyone
- Whether the quote is based on a survey or photos
- Exactly which parts of the system are covered
- What happens if part of the system cannot be accessed
- When they can work, and whether that is outside your opening hours
What we do, step by step
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. After that, the work takes one overnight shift for many single units, with bigger plant phased. Photos of the system and how to reach it help us plan a visit to Well.
- We agree a shutdown window that suits the building.
- We take before photos of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
How to prepare
- Agree a time when the area can be out of use
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
How to get a quote
Getting a quote doesn’t take long. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party and send the paperwork to whoever needs it.
We regularly work with managing agents. Send the address, what’s needed and how access works and we will come back with a fixed quote.
