Air handling unit cleaning in Hensting, Hampshire
Our technicians work in Hensting on air handling unit cleaning. Fixed quotes, work around your opening hours and photo reports as standard.
- Air handling units never cleaned inside
- Dirty fans and fan housings
- Filters that are clogged or overdue
How it works
There are three stages on the day: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and photos. The middle part takes longest, and that takes half a day to a full day per unit, with large plant planned over several shifts. If the van will struggle with a lane or gateway near Hensting, let us know and we’ll plan around it.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
How to prepare
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards
- Let us know about parking and loading
Getting a quote
For a fixed quote, call 0345 646 2711 or drop us a line and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We normally come back within one working day.

AHU cleaning in Hensting, done properly
If the units serving a building in Hensting have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full clean deals with all of it. If you are dealing with dirty fans and fan housings and leaves and litter drawn into the unit, we can put it right, from dampers and louvres, supply and extract fans and drain trays onwards.
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.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

What affects the quote in Hensting
The quote reflects the site in front of us. We consider:
- The condition of the system
- Whether we need access equipment or extra panels
- Any permits to work or inductions
- The number of sites or systems
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What to send for a quote
What to send for a quote:
- The postcode and the type of business
- When the site is open and when it’s quiet
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
Quotes are quick. Send a few details and photos, and we normally reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.

What a clean will not put right
AHU cleaning can’t fix everything, and we’d rather say so up front. It does not solve:
- Building management system faults
- Airflow problems caused by the system’s design
- Mechanical faults with motors, belts or bearings
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly.

AHU cleaning around Hensting
The FSA’s food hygiene register lists about 3 care, childcare and hospital premises with registered kitchens or food service within 1.5 miles or so of the middle of Hensting. Busy, occupied buildings like these are where clean supply air matters most. For Hensting, the closest hospital is St John's Rooms And Chapel, roughly 4.3 miles north. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
In Hensting, we look inside the system before deciding what needs cleaning. If you run a surgery, dental practice or care home near Hensting, clean ventilation matters as much to you as to a hospital like St John's Rooms And Chapel (about 4.3 miles north).

Multi-site and managed buildings
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 the report can go to both.
For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
What the work involves, part by part
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
What happens if it’s left?
A light clean now is simpler than a heavy one later. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. A fault that closes a site in a village like Hensting affects everyone who depends on it.
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. You’ll have a fixed price before we start.

What staff can safely do
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
