AHU cleaning in Purbrook
Our AHU cleaning covers sites in Purbrook 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. We’re often asked to deal with filters that are clogged or overdue and condensate trays that won’t empty, on heating and cooling coils, drain trays and internal panels.
Buildings in towns like Purbrook often have ventilation added in stages, with units on the roof or in a plant room. The work starts with an inspection to decide what needs cleaning, so you’re not paying for more than the system needs.
We are CHAS and SafeContractor accredited, we hold ISO 9001 and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Why deal with it now?
Dirt left in an air handling unit doesn’t stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. A fresh certificate on file is the best thing to have when someone asks to see your records.
The price reflects the work, not guesswork. That’s why every job is surveyed first, and why the quote is fixed before work begins.

Keeping the system healthy
So the system stays in good health:
- Plan the next inspection before the last report gets filed away
- Keep the area around the fresh air intake clear
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
Keep filter changes on schedule between cleans, as that does more than anything to keep the unit clean. Record each change in the maintenance log.
Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
When something else is needed
A few issues sit outside what this work can do:
- Dirty ducts beyond the unit itself
- A system that is undersized for the building
- Controls and BMS settings that run the unit
If you are not sure, just give us a ring on 0345 646 2711 or drop us a line and we’ll give you a straight answer before you book.

What your team can do, and what needs us
Staff cleaning does not 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.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Common questions in Purbrook
Do you cover Purbrook for AHU cleaning?
Yes, Purbrook is covered. Just call us on 0345 646 2711 or email us with a few details of the site.
Do you clean school ventilation in Purbrook in the holidays?
Yes. The holidays are the usual time for school work. Around Purbrook, the Food Standards Agency lists about 10 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
Will you repair the fan or motor?
Mechanical repairs to the unit are for your HVAC maintenance contractor. We will flag anything we notice during the clean.
Do you clean the ductwork as well?
Yes. We clean supply and extract ductwork to TR19® Air as well. Cleaning the unit and ducts together often makes sense, and we can quote for both.
Do you look at the system first?
Yes. For many sites, pictures and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. Each report recommends when the next visit should be.
What do you do to protect the area?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
How often do AHUs need cleaning?
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.
Signs you need AHU cleaning in Purbrook
Dirt in an AHU matters in two ways: air quality, since the unit feeds occupied rooms, and performance, since dirt makes it strain. For the people using the building every day, that’s the air they breathe for hours on end.
Clients normally contact us when they notice one of these:
- Intake sections clogged with outdoor debris
- Units needing a clean before a new tenant or handover
- Drain trays holding standing water
- Units that have only ever had filter changes
Classrooms and halls at schools such as Purbrook Junior School are easiest to work in when pupils are away.

What happens on the day
Night work is normal for us. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a single shift for a typical unit, longer for large or heavily soiled ones. For a site in a town like Purbrook, tell us your opening hours, where we can park and how we reach the roof or plant.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- The fan and drain tray are cleaned and the drain checked.
- After pictures are taken and the certificate issued.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Let us know about parking and loading
Getting a quote
Some systems can be priced from photos; others need a survey. 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.
Advice
Different parts, different methods
Drain trays
Drain trays can rust and leak over time. We record their condition with pictures so you can decide on any repairs.
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.
