How we handle AHU cleaning in Church Crookham
If the units serving a building in Church Crookham have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. The work covers heating and cooling coils, filter sections and drain trays, and the jobs we see most are plant that needs cleaning after a refit and intake sections clogged with outdoor debris.
Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, which makes them easy to overlook.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

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.
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. They’re cleaned using methods that won’t bend or flatten the fins.
Do you need AHU cleaning in Church Crookham?
Most units live out of sight on roofs, in plant rooms or in ceiling voids and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.
Keep an eye out for these warning signs:
- Air handling units with blocked filters
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Fan sections that haven’t been cleaned in years
Healthcare ventilation, from large hospitals like Fleet Community Hospital (about 1.8 miles north-west) to small clinics, depends on clean filters, coils and ducts.
Questions to ask before booking
- Whether a written report and photos are included
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
- Whether the quote shows VAT
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
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 can diagnose it and quote.
Ventilation in Church Crookham buildings
There are about 13 hospitals, care homes and childcare premises and about 3 hotels, B&Bs and guest houses on the FSA’s food hygiene register across Church Crookham and its immediate surroundings (about a mile and a half). Buildings like these often rely on mechanical ventilation, which TR19® Air covers. At about 35 miles from central London, Church Crookham sits well inside the area we cover. Evening, overnight and weekend visits are all possible. Fleet Community Hospital is the nearest hospital, about 1.8 miles north-west of Church Crookham. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Velmead Junior School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Your questions about AHU cleaning in Church Crookham
Can a school’s ventilation in Church Crookham be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. Around Church Crookham, the Food Standards Agency lists about 2 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.
Can you get to a site in Church Crookham?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Can you clean the AHU out of hours?
Yes. The clean is planned around when the unit can be switched off. In hospitals and care homes, we agree timings with the site team.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Do you repair air handling units?
Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We clean the unit and report anything we see that needs attention.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
What information do you need?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. Work is timed around how each site runs.
How the visit works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. A few photos of the system help us make the most of a visit to a place like Church Crookham.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Have your last certificate or report to hand
- Move anything stored near the system
- Tell us where we can park and unload

We will always give you a straight diagnosis, so here’s what AHU cleaning will not do:

- Dirty ducts beyond the unit itself
- Controls and BMS settings that run the unit
If you are not sure, just ring 0345 646 2711 or use the quote form and we will give you a straight answer before you book.

How we price AHU cleaning
The quote reflects the site in front of us. We take into account:
- How easy every part is to reach
- The condition of the system
- Whether several sites go on one quote
- Travel, parking and unloading
Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
Asking for a quote
Before you ask for a quote, gather:
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- The site address and the type of premises
Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.
