How we handle AHU cleaning in Hascombe
Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers dampers and louvres, supply and extract fans and filter sections, and the jobs we see most are air handling units with blocked filters and air handling units never cleaned inside.
Somewhere as small as Hascombe, ducted ventilation is usually limited to a school, a care home, a surgery or a converted business building, wherever there is one, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Insurers, fire officers and environmental health officers all look at records. That is why every job is written up in a report with pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How the job changes from site to site

Internal casing and panels
Access doors and panels are opened in turn and closed properly afterwards before the unit is handed back.
Hascombe buildings and their air
For Hascombe, the closest hospital is Milford Hospital, roughly 2.6 miles north-west. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Hascombe is about 32 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
For buildings in and around Hascombe, TR19® Air cleaning starts with an inspection.

Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
How it works
We start by comparing what we find with the survey or your pictures. Anything unexpected is raised with you before we go further. After that, the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Somewhere as small as Hascombe, the date and timings are agreed with you well before the day.
- The survey covers the unit, its access and how it can be shut down.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
How to prepare
- Dig out any earlier paperwork for the system
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.

Landlords, agents and facilities managers
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
Common problems we fix in Hascombe
Air handling units are normally tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. Months can pass without anyone looking inside.
If you notice any of these, it’s worth a diagnosis:
- Stale or musty smells from the ventilation
- Leaves and litter drawn into the unit
- Air handling units with blocked filters
- Condensate trays that will not empty
Healthcare buildings such as Milford Hospital, about 2.6 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Hascombe, yours matters too.

Your questions about AHU cleaning in Hascombe
Do you cover Hascombe for AHU cleaning?
Yes. We work across London and the South East, and Hascombe is part of that. Just call us on 0345 646 2711, or send details by email with a few details of the site.
Do you cover smaller places like Hascombe?
Yes, smaller places are covered as well as towns. A survey first, from pictures or a visit, means we arrive with the right kit.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What do you clean inside the unit?
All the internal parts the air touches, from the intake and filters through the coils and fan to the outlet. You get a photo report showing each part before and after.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It isn’t law, but it’s the benchmark.
How often do AHUs need cleaning?
Under TR19® Air, cleaning is led by inspection and risk rather than a set calendar. Each report suggests when the unit should next be looked at.
Does the AHU have to be shut down for cleaning?
Yes, while the clean is under way. Out-of-hours work is available to keep disruption down.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Why deal with it now?
Dirty coils and fans make the unit strain to move the same air. The result is extra wear and a building that does not feel as comfortable, and a clean on your terms beats a breakdown on nobody’s. In a small place like Hascombe, a system that fails can take a site out of use.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
