AHU cleaning in Liphook, done properly
Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Whatever builds up inside it travels with that air, which is why we clean the unit itself, not just the ducts. We are often asked to deal with plant that has been serviced but not cleaned and intake sections clogged with outdoor debris, across filter sections, dampers and louvres and drain trays.
Around a place like Liphook, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Smaller systems still gather dust and need inspecting.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
We also work for facilities teams across offices, schools and healthcare in Liphook and across Hampshire. Work can be phased by floor, building or site around the people who use them.
Why it’s worth doing now in Liphook
Stuffy rooms and stale smells in a building in Liphook can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Even a site near Liphook that is only busy part of the week needs its system checked on a schedule.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
What you get with us

When to call us in Liphook
Wherever there’s a cooling coil, there’s condensate. A blocked outlet or a badly sloped tray leaves standing water, and slime and smells soon follow.
Keep an eye out for these warning signs:
- Dirty fans and fan housings
- Units needing a clean before a new tenant or handover
- Air handling units never cleaned inside
- Leaves and litter drawn into the unit
Classrooms and halls at schools such as Bohunt School are easiest to work in when pupils are away.
What to look for in a quote
- Whether they recommend a next date
- Proof of insurance
- Proof of accreditation you can verify
- Whether the quote shows VAT
What affects the cost of AHU cleaning
The diagnosis comes before the price. We look at:
- Parking and loading at the site
- The size of the system
- What state the system is in
- A single visit or a regular plan
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
Many jobs can be priced from photos and some basics. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Detail shots of panels, filters and grilles
- Your last certificate, test record or report
Quotes are quick. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Liphook: your questions answered
Can the work in Liphook be done at night or at weekends?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Is Liphook within the area you cover?
Yes, Liphook is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
How much does AHU cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711, or email photos and tell us about the site and its opening hours.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How often should an air handling unit be cleaned?
It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.
Can you price the work without visiting?
Often, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.
Are you fully insured?
Yes, we are fully insured. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Will we get paperwork for the AHU clean?
Yes. You get a TR19® certificate plus before and after photos. They’re worth keeping with the plant records.
How the job changes from site to site
Fans and fan sections
Before the fan is touched, the unit is shut down and made safe with your site team.
Filters
Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.

How the visit works
Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, tidy up and hand over the paperwork. On site, the work takes a single shift for a typical unit, longer for large or heavily soiled ones. Your opening hours decide when we come to Liphook, not ours.
- We start with a survey of the unit and a fixed quote for the work.
- 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.
- Standing water and slime come out of the tray and the drain is checked.
- A TR19® certificate and photo report follow the clean.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Clear loose items from the work area
- Let us know about parking and loading
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.
