How we handle AHU cleaning in Locks Heath
Our AHU cleans for sites in Locks Heath cover the parts that collect dirt: filters, coils, drain trays, fans and the internal panels. You get a TR19® certificate and a photo report showing the unit before and after. If you have dirty coils holding back the airflow and dust built up on fan impellers, we can put it right, from supply and extract fans, heating and cooling coils and dampers and louvres onwards.
Visits to a place like Locks Heath are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

For landlords and multi-site operators
Whether it’s one building or many, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and photos, so you can show an insurer or inspector what was done at each site.
Different parts, different methods
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
Filters
What’s on the filters is a good clue to what’s further in. We photograph them for the report.
Questions from Locks Heath
Can a school’s ventilation in Locks Heath be done out of term time?
Yes, and it’s the easiest time to do it. Around Locks Heath, the Food Standards Agency lists about 11 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work at weekends in Locks Heath?
Yes, out-of-hours work is a big part of what we do. It means the site in Locks Heath keeps running as normal. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
What happens if you can’t reach some of it?
The report shows them clearly. In ductwork, new access panels are often the answer, and we can fit those.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Can you clean the ducts connected to the AHU?
Yes, supply and extract ducts, grilles and diffusers. We will tell you after the survey whether the ducts need it.
Which kinds of sites do you work on?
Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, plus food production and leisure sites.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with the details in the report.
What a clean will not put right
To be straight with you, there are a few things this work will not fix:
- Coils that are corroded or leaking and need replacing
- Dirty ducts beyond the unit itself
- Airflow problems caused by the system’s design
If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
Where we work
- Supply and extract fans
- Filter sections
- Heating and cooling coils

- Drain trays
Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Look at the condensate drain whenever the unit is serviced
- Note any water around the unit or leaks below it
- Store the TR19 paperwork where auditors can find it
- Book the next check in line with the report
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Keep the unit’s doors and panels in working order. If a section is hard to get into, it tends not to get checked.
Locks Heath buildings and their air
The FSA’s food hygiene register lists about 11 schools, colleges and universities and about 27 caring premises (care homes, nurseries and hospitals) with registered kitchens or food service across Locks Heath and its immediate surroundings (about a mile and a half). Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. About 0.6 miles north-west of Locks Heath is Fareham Community Hospital, the nearest hospital. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
If you manage shops or offices close to Swanwick station, a TR19® Air inspection shows whether the ductwork needs cleaning. Healthcare buildings such as Fareham Community Hospital, about 0.6 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near Locks Heath, yours matters too.

How we price AHU cleaning
The survey tells us what the work involves. We look at:
- Whether several sites go on one quote
- How easy every part is to reach
- Site requirements such as sign-in and permits
- The condition of the system
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.
What we need to know
We can often survey from pictures. Try to include:
- How we’d reach plant on a roof or in a plant room
- The times we could work without disrupting the site
- Wide pictures of the system and the area around it
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, give us a ring on 0345 646 2711 or email us.
What we do, step by step
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes half a day to a full day per unit, with large plant planned over several shifts. Around Locks Heath, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- We survey the unit from pictures or on site and agree what’s included.
- We arrange the shutdown with your staff and sheet the area.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Drain trays are cleared and cleaned and the outlet checked.
- We close up the unit and send the certificate and before and after pictures.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Tell us about site rules, permits or sign-in
- Mention any parking or loading restrictions
Get a fixed quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Advice
Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
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.
