Common questions in Langley Vale
Do you work in villages like Langley Vale?
Yes. Villages and rural sites across the South East are part of our work, Langley Vale included. Just mention lanes, gates or anything else about the site when you book.
Can you work in Langley Vale outside opening hours?
Yes, evening, overnight and weekend work is normal for us. That way a site in Langley Vale does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Do you have insurance?
Yes, we’re fully insured. CHAS and SafeContractor accreditation sit alongside it, for sites that check contractor safety.
Do you repair air handling units?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We clean the unit and report anything we see that needs attention.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
Do you need to switch the unit off?
Yes. Cleaning needs the unit off and isolated, and we time the work to suit the site.
How much notice should we give?
For planned work, earlier is better, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
How often do AHUs need cleaning?
That is set by inspection, in line with TR19® Air. Units in heavy use or in sensitive buildings may need attention more often.
How we handle AHU cleaning in Langley Vale
An air handling unit is the heart of a building’s ventilation: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, so cleaning the unit matters as much as cleaning the ducts. If you have filters that are clogged or overdue and rooms that smell stuffy when the system runs, we can help.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
Good records are part of the job. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

How the job changes from site to site
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins aren’t damaged.
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.

Fixed quotes for AHU cleaning in Langley Vale
You’ll get a fixed price before we start. It takes into account:
- A single visit or a regular plan
- The scale of the work
- What state the system is in
- Where the site is and how we reach it
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 we start.
What to send for a quote
To speed up the quote, send us:
- Any symptoms, from odd noises to smells or leaks
- Any previous report or certificate
- The postcode and the type of business
- The roof, plant room or outside wall the system runs to
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
The process
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Visits to a village like Langley Vale are booked in advance, at a time that suits whoever runs the site.
- We survey the unit from photos or on site and agree what’s included.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- We close up the unit and send the certificate and before and after photos.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
- Clear loose items from the work area
