- Air handling units due a clean after building work

The process
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and pictures. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. Pictures of the system and its access let us plan the work in Christmas Pie before we set off.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before photos of each section of the unit.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- We take after photos and issue the certificate and report.
Before we arrive
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

How we handle AHU cleaning in Christmas Pie
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. We’re often asked to deal with leaves and litter drawn into the unit and plant that has been serviced but not cleaned, on heating and cooling coils, drain trays and supply and extract fans.
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’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

FAQs for Christmas Pie
Do you work at weekends in Christmas Pie?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Christmas Pie needn’t be disturbed. Let us know the hours you are closed and we will book within them.
Can you do AHU cleaning in Christmas Pie?
Yes, we work in Christmas Pie and the places around it. A fixed quote usually follows within one working day of the survey details.
Will we get paperwork for the AHU clean?
Yes, a TR19® certificate and a photo report. It includes a recommended date for the next check.
Do you look at the system first?
Yes. For many sites, photos and a few details are enough, and larger or hidden systems get a visit.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, and we can fit those.
How long does it take to clean an air handling unit?
Expect it to take from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.
Aftercare tips
After the visit, a few habits help the work last:
- Flag stale or damp smells in the supply air
- Keep filter changes on time and recorded
- Report water on the plant room floor
- Diary the inspection date recommended in the report
Keep filter changes on schedule between cleans, because good filters protect everything downstream. Record each change in the maintenance log.
Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
What affects the quote in Christmas Pie
Before we fix a price, we need to know a few things. We look at:
- Whether we need access equipment or extra panels
- The size of the system
- The condition of the system
- Site rules, permits and inductions
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
Helping us quote
When you contact us, these details help:
- Photos showing the whole system and its surroundings
- The roof, plant room or outside wall the system runs to
- Your opening hours and when the area is out of use
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.
Why it’s worth doing now in Christmas Pie
A clogged coil or dirty fan makes the unit work harder for the same airflow. The result is extra wear and a building that does not feel as comfortable, and a planned clean is far less disruptive than a breakdown. In a place like Christmas Pie, ductwork and fans are easy to forget until something goes wrong.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll go through it with you.
Why us?
- Out-of-hours work and a 24/7 emergency line
- We are fully insured

When to call us in Christmas Pie
Whatever surrounds a building in Christmas Pie, the air drawn into its AHU carries dust, pollen and debris. The intake section and first filters take the brunt, and some travels further into the unit.
These are the problems we see most often:
- Dirty filters cutting the airflow
- Condensate trays that will not empty
- Plant that needs cleaning after a refit
- Units that have only ever had filter changes
Healthcare buildings such as Guildford Hospital, about 2.6 miles east, depend on their ventilation; if you manage a surgery, clinic or care home near Christmas Pie, yours matters too.
Questions to ask before you book
- Whether the price is fixed
- What happens if part of the system cannot be accessed
- Whether the quote is based on a survey or photos
- How they set the interval to the next visit
What a clean will not put right
We’d rather tell you now than book work that will not help, so these are the things it won’t cover:
- Airflow problems caused by the system’s design
- Controls and BMS settings that run the unit
- Leaking heating or cooling coils
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we will tell you honestly.
What the work covers
- Supply and extract fans
- Internal panels
- Heating and cooling coils
- Dampers and louvres
- Drain trays
- Filter sections
In-house cleaning or a specialist?
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’ll take a look and give you a fixed quote.
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Christmas Pie buildings and their air
Going by the FSA’s register, there are about 4 caring premises (care homes, nurseries and hospitals) serving food within 1.5 miles or so of the middle of Christmas Pie. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. We cover Christmas Pie, about 31 miles from central London, as part of our work across London and the South East. We work evenings, overnight and at weekends, so the visit fits around the site. For Christmas Pie, the closest hospital is Guildford Hospital, roughly 2.6 miles east. Healthcare buildings depend on clean supply and extract ventilation, and the same applies to surgeries, clinics and care homes.
Wherever a school like Puttenham CofE Infant School has ducted ventilation, a half-term visit keeps the work out of lesson time. If you run an office near Wanborough station, its supply ductwork can gather dust for years before anyone looks inside.
