AHU cleaning in Corhampton
Coils are where a lot of the dirt ends up. A coated coil restricts airflow and makes the unit work harder. Coils are cleaned carefully, with methods chosen so the fins are not flattened. The work covers filter sections, dampers and louvres and internal panels, and people most often call us about dust built up on fan impellers and intake sections clogged with outdoor debris.
In a village or hamlet like Corhampton, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

FAQs for Corhampton
Can you get to a site in Corhampton?
Yes, Corhampton is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Can you come to Corhampton after we close?
Yes, out-of-hours work is a big part of what we do. That way a site in Corhampton doesn’t have to lose a day’s trading. Just ring 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
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 to keep disruption down.
Which parts of an air handling unit do you clean?
Filters, coils, drain trays, the fan and the internal surfaces are all covered. Filters are cleaned or changed as agreed in the quote.
Do you survey before quoting?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Which accreditations do you hold?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we’re fully insured.
How much does AHU cleaning cost?
There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before we start.

What’s near Corhampton
Around Corhampton, our work takes us to kitchens and buildings near The Shoe Inn and the streets around them. Not far away are Beacon Hill and St Clair's Meadow.
Part by part
Rooftop and plant room units
Ceiling-mounted and compact units are cleaned too. The space underneath is protected with sheeting first.
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.
Looking after it afterwards
How long the results last depends on use and care. We suggest:
- Diary the inspection date recommended in the report
- Don’t ignore odours coming through the grilles
- Stick to the filter change plan
- Keep inspection doors on the unit in good order
The report shows each section of the unit before and after, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.
Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.
The process
Everything the job needs comes with us, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit 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 Corhampton.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Each section is cleaned of dust, debris and slime.
- Coils and trays are cleaned and the condensate drain cleared.
- The unit is closed up and handed back, with a report to follow.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Let us know about parking and loading
Ask for a quote
Some systems can be priced from pictures; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, the quote is fixed before any work is booked.
Related advice
Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
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.
Signs you need AHU cleaning in Corhampton
Filters that aren’t changed or cleaned on time clog up, 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
- Debris and leaves in the fresh air intake
- Condensate trays that won’t empty
- Coils clogged with dust and debris
Wherever a school like Meonstoke Church of England Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time.
Questions to ask before booking
- When they can work, and whether that’s outside your opening hours
- Whether a survey comes first
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
What AHU cleaning cannot fix
In fairness, there are a few things this work will not fix:
- Airflow problems caused by the system’s design
- Breakdowns that need a mechanical engineer
- Problems with the unit’s controls or sensors
If in doubt, phone us on 0345 646 2711 or send us an email and we will say what we think.
Parts of the system we cover

Leave it or put it right?
If people in a building in Corhampton complain about stuffy or smelly air, the AHU is worth looking at. A clean tackles the source instead of masking it. In a small place like Corhampton, a system that fails can take a site out of use.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we will explain each part.
