What AHU cleaning looks like in Worth
There are about 14 schools, colleges and universities, about 17 caring premises (care homes, nurseries and hospitals) and about 4 hotels and B&Bs on the FSA’s food hygiene register within about 1.5 miles of central Worth. Busy, occupied buildings like these are where clean supply air matters most. We cover Worth, about 27 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible. Crawley Hospital is the nearest hospital, about 2.2 miles west of Worth. Hospitals show how much a building can rely on its ventilation, and smaller healthcare sites rely on theirs too.
School buildings such as Maidenbower Junior School are normally done in the holidays, so classrooms aren’t disturbed. If you manage offices or shops near Three Bridges station, their ventilation can be inspected and cleaned out of hours.

AHU cleaning in Worth, done properly
If the units serving a building in Worth have only had filter changes for years, there may be dirt on the coils, fan and casing that nobody has looked at. A full AHU clean takes in the whole unit. If you’re dealing with dirty fans and fan housings and dirty coils holding back the airflow, we can put it right, from heating and cooling coils, drain trays and filter sections onwards.
For a building near Worth, the visit is planned around how it’s used, and the journey is planned ahead. The work is the same as in any town: inspect, clean, record.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How we price AHU cleaning
The quote reflects the site in front of us. We consider:
- Whether several sites go on one quote
- Parking and loading at the site
- The condition of the system
- One-off work versus a regular cycle
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
Helping us quote
You do not need the technical terms. It helps if you can send:
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- The postcode and the type of business
- Your last certificate, test record or report
Some systems can be priced from pictures; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before any work starts.
Aftercare tips
Simple habits between visits make a real difference. We recommend:
- Don’t ignore odours coming through the grilles
- Check the drain tray is emptying during routine visits
- Keep filter changes on time and recorded
- Do not store bins or materials near the intake
Stick to the filter change schedule, because good filters protect everything downstream. Record each change in the maintenance log.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
What we are called out for in Worth
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
It’s time to book a visit if you see:
- Fan sections that haven’t been cleaned in years
- Air handling units with blocked filters
- Units needing a clean before a new tenant or handover
- Air handling units never cleaned inside
If you run a surgery, dental practice or care home near Worth, clean ventilation matters as much to you as to a hospital like Crawley Hospital (about 2.2 miles west).

How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Visits to a place like Worth are planned ahead, so we arrive with what the survey says the job needs.
- We agree a shutdown window that suits the building.
- Before cleaning, each section is photographed.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after photos and issue the certificate and report.
Preparing for the visit
- Clear loose items from the work area
- Find the previous report, if there is one
- Arrange a key holder or contact on site

Managing agents and facilities teams in Worth
Keeping records across a portfolio is half the battle. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept on a regular cycle.
Why act early in Worth
Dirty coils and fans make the unit strain to move the same air. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. It’s easy to lose track of when the work was last done on a quieter site.
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
What you get with us
- Trading since 2009
- Fully insured
- Evenings, overnight and weekends, plus 24/7 emergency callout
- CHAS, SafeContractor and ISO 9001
Different parts, different methods
Heating and cooling coils
Coil fins are close together and catch the dust the filters miss. We clean them with care so the fins are not damaged.
Fans and fan sections
The fan moves all of the unit’s air, so dirt on it gets spread around. The impeller, its housing and the fan chamber are cleaned.
FAQs for Worth
Can you come to Worth after we close?
Yes. We work evenings, overnight and at weekends. The work in Worth can fit around your hours. Let us know the hours you’re closed and we will book within them.
Do you work in villages like Worth?
Yes. Worth is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
What do you clean inside the unit?
We clean the filter section, heating and cooling coils, drain trays, fan and internal casing. Filters are cleaned or changed as agreed in the quote.
Is a quote from pictures possible?
Typically, yes. Send a few wide photos plus close-ups of panels, filters or grilles, and we normally come back within one working day. If pictures aren’t enough, we will survey first.
What do you do to protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
What if parts of the system cannot be reached?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, which we can install.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, and we time the work to suit the site.
