Air handling unit cleaning in Hook, Hampshire
Professional AHU cleaning in and around Hook, timed so the site keeps working and finished with a written report and pictures.
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
- Dirty coils holding back the airflow
Different parts, different methods
Drain trays
A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and note if the slope or the drain needs attention.
Filters
Filter condition tells you a lot about the rest of the unit. We photograph them for the report.
AHU cleaning in Hook, done properly
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 supply and extract fans, drain trays and internal panels, and people most often call us about plant that needs cleaning after a refit and coils clogged with dust and debris.
Visits to a place like Hook are fitted around opening hours. The work is the same as in any town: inspect, clean, record.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too across Hampshire. Larger estates can be phased building by building around the people who use them.
We work for landlords, managing agents and facilities managers as well as the people running the site. 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.

What else we do in Hook
Aftercare tips
Once we have finished, these simple steps help:
- File each AHU report in the maintenance log
- Change filters on schedule and log each change
- Flag stale or damp smells in the supply air
- Report water on the plant room floor
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
When it’s something else
Not every problem is solved by AHU cleaning, and we’d rather say so up front. It doesn’t solve:
- Controls and BMS settings that run the unit
- Ventilation that was badly designed in the first place
- Leaking heating or cooling coils
If in doubt, call us on 0345 646 2711, or send details by email and we will say what we think before you book.

What your team can do, and what needs us
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Hook questions
Can you clean school ventilation in Hook during the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 3 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Hook. Tell us your holiday dates and we will book the visit for when the site is empty.
Can the work in Hook be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Hook doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
What happens to the waste?
It leaves the site with us at the end of the visit. During the work, it’s contained to keep the area clean.
Do you do ventilation duct cleaning too?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, and new panels can be fitted.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
How long does an AHU clean take?
As a guide, it takes anything from half a day for one small unit to several shifts for a plant room full of them. We plan the shutdown around that, out of hours if needed.
When should our AHU next be cleaned?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. We recommend a next date in each report.
How much does AHU cleaning cost in Hook?
It depends on the site, so we quote each one individually. For a quote, give us a ring on 0345 646 2711, or send details by email with the site type, opening hours and a few photos.
Hook buildings and their air
Food Standards Agency records list about 3 schools, colleges and universities, about 3 care, childcare and hospital premises and about 3 hotels and guest houses registered as food businesses within 1.5 miles or so of the middle of Hook. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. About 4.7 miles east of Hook is Fleet Community Hospital, the nearest hospital. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients. Hook is about 40 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.
Hospitals such as Fleet Community Hospital (about 4.7 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Hook are no different. If you manage a school such as Hook Junior School, ventilation cleaning is best booked for the holidays.

When to call us in Hook
Mechanical servicing keeps a unit running, but it doesn’t always include cleaning the inside. So a unit can be well maintained and still dirty.
It’s time to book a visit if you see:
- Drain trays holding standing water
- Dust-coated heating and cooling coils
- Dirty fans and fan housings
- Units that have only ever had filter changes
If you manage offices or shops near Hook station, their ventilation can be inspected and cleaned out of hours.

How the visit works
The visit has three parts: 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 pictures. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. Everything the job in Hook needs is worked out beforehand, from the survey.
- We survey the unit from photos or on site and agree what’s included.
- The unit is shut down with your site team and the area protected.
- 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
- Plan for cooking equipment or plant to be off before we arrive
- Let us know about parking and loading
- Let us know when the site is closed or quiet
Getting a quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.
