Leave it or put it right?
When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. Equipment tucked in a roof space or outbuilding near Durrants rarely gets looked at unless someone books it.
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered, and you will get one fixed quote.

About our AHU cleaning in Durrants
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. We are often asked to deal with dirty coils holding back the airflow and stale or musty smells from the ventilation, across supply and extract fans, dampers and louvres and filter sections.
For a building in or near Durrants, access is agreed in advance and the visit is planned around the journey.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

AHU cleaning around Durrants
The FSA’s food hygiene register lists about 11 hospitals, care homes and childcare premises and about 3 hotels and guest houses with registered kitchens or food service within about 1.5 miles of central Durrants. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. At about 57 miles from central London, Durrants sits well inside the area we cover. Evening, overnight and weekend visits are all possible. For Durrants, the closest hospital is Havant War Memorial Hospital, roughly 2 miles south-west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
Wherever a school like Havant Academy has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near Rowlands Castle station, its supply ductwork can gather dust for years before anyone looks inside. Hospitals such as Havant War Memorial Hospital (about 2 miles south-west) show how much a building can rely on clean ventilation, and smaller healthcare sites near Durrants are no different.

What AHU cleaning cannot fix
We’d rather tell you now than book work that will not help, so these are the things it will not cover:
- Ductwork downstream of the unit, which is a separate clean
- Breakdowns that need a mechanical engineer
- Leaking heating or cooling coils
If you’re not sure, just call 0345 646 2711, or send details by email and we will give you a straight answer.
Where we work
- Heating and cooling coils
- Filter sections
- Drain trays
- Supply and extract fans
- Dampers and louvres
- Internal panels
How the visit works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes from a few hours for a compact unit to a day or more for a large one. Photos of the system and how to reach it help us plan a visit to Durrants.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- We clean or change the filters as agreed, then clean the coils, fan and internal panels.
- We clean out the drain tray and make sure it drains.
- We close up the unit and send the certificate and before and after photos.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Clear the space around the work
- Agree a time when the area can be out of use
Getting 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, you get a fixed price before we start.
Related advice
Different parts, different methods
Rooftop and plant room units
Rooftop units take the weather, and intakes can collect leaves and debris. The intake section gets particular attention.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. We check them, and clean or change them as agreed in the quote, and the housing around them is cleaned too.
Common questions in Durrants
Can you get to a site in Durrants?
Yes, we work in villages as well as towns, and Durrants is covered. Photos of the system and directions to the site help us plan the visit.
Do you do school ventilation cleaning in Durrants in the summer holidays?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Durrants. Booking early in the term gives the best choice of holiday dates.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How often do AHUs need cleaning?
Inspection under TR19® Air decides it. Units in heavy use or in sensitive buildings may need attention more often.
Is there a report after cleaning?
Yes. You receive a certificate and a report showing each section before and after, including anything we think needs attention.
How long does it take to clean an air handling unit?
Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. Size, layout and how dirty it is decide the rest, and we’ll confirm the time when we quote.
Do you do ventilation duct cleaning too?
Yes. Ductwork is cleaned through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where needed.
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.
Fixed quotes for AHU cleaning in Durrants
The diagnosis comes before the price. The main factors are:
- A single visit or a regular plan
- The condition we find in the survey
- How many systems or sites are involved
- Site rules, permits and inductions
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.
What to send for a quote
When you contact us, these details help:
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Facilities teams in offices, schools and healthcare sites book us too in Durrants and across Hampshire. Work can be phased by floor, building or site around the people who use them.
Aftercare tips
Good habits slow the build-up between visits. Our tips:
- Keep inspection doors on the unit in good order
- Keep the certificate and photo report with the plant records
- Keep filter changes on time and recorded
- Clear leaves and litter away from the intake
Photos in the report cover the filters, coils, drain tray, fan and casing, and note any part we couldn’t get to. It also notes faults we spotted, such as damaged panels or a blocked drain.
Make the drain tray part of every maintenance visit. A drain that is cleared early never gets to the slime stage.
