AHU cleaning for kitchens and businesses in Hazeley
Our AHU cleaning covers sites in Hazeley and the rest of Hampshire, in offices, schools, hospitals, care homes and retail. Units are cleaned when the site can spare them, often evenings, overnight or weekends. The work covers filter sections, supply and extract fans and drain trays, and the jobs we see most are blocked condensate drains and slimy trays and intake sections clogged with outdoor debris.
For a building in or near Hazeley, access is agreed in advance and the visit is planned around the journey.
Think of the report as the system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

When to call us in Hazeley
An overdue filter loads up with dirt, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Signs it’s time to call us include:
- Air handling units never cleaned inside
- Coils clogged with dust and debris
- Filters that are clogged or overdue
- Rooms that smell stuffy when the system runs
Healthcare ventilation, from large hospitals like Fleet Community Hospital (about 4.6 miles south-east) to small clinics, depends on clean filters, coils and ducts.
Before booking anyone
- Whether they’re fully insured
- Whether the figure could change on the day
- What hours they’ll be on site
- What paperwork you get at the end
Staff cleaning versus specialist work
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Different parts, different methods
Internal casing and panels
Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.
Filters
What’s on the filters is a good clue to what’s further in. They’re photographed before and after for your records.
Fixed quotes for AHU cleaning in Hazeley
Before we fix a price, we need to know a few things. We look at:
- Site requirements such as sign-in and permits
- How many systems or sites are involved
- How big the system is
- One-off work versus a regular cycle
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you are unsure, call us on 0345 646 2711 or email us for straight advice and a fixed quote.
Helping us quote
When you contact us, these details help:
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- A few general shots of the system
- The times we could work without disrupting the site
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Looking after it afterwards
How long the results last depends on use and care. Here’s what we suggest:
- Keep the area around the fresh air intake clear
- Plan the next inspection before the last report gets filed away
- Check the drain tray is emptying during routine visits
- Report water on the plant room floor
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Regular filter changes are the best protection an AHU has. Overloaded filters let more dirt through to the coils and fan.
Questions from Hazeley
Do you work overnight in Hazeley?
Yes, out-of-hours work is a big part of what we do. That way a site in Hazeley doesn’t have to lose a day’s trading. Just phone us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
Is Hazeley within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What accreditations do you have?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’ve been trading since 2009 and we are fully insured.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, and visits can be set on a regular cycle.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
Where does the waste go?
It’s contained and taken away. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
Are you fully insured?
Yes, fully. We also hold CHAS and SafeContractor for clients who vet their contractors.
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.
