Air handling unit cleaning in Rowledge, Surrey
Need AHU cleaning in Rowledge? We survey first, give you a fixed quote and work around your opening hours, finishing with a written report and pictures.
- Dirty filters cutting the airflow
- Dust-coated heating and cooling coils
- Units needing a clean before a new tenant or handover
Common problems we fix in Rowledge
Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. After that, the coils and fan collect what the filter should have caught.
Common reasons sites call us are:
- Condensate trays that won’t empty
- Debris and leaves in the fresh air intake
- Air handling units due a clean after building work
- Air handling units never cleaned inside
If you manage a school such as Rowledge Church of England Controlled Primary School, ventilation cleaning is best booked for the holidays.

How we handle AHU cleaning in Rowledge
The fan pushes every bit of air in the system, so dirt on the impeller and housing gets spread around. Fan, housing and the surrounding panels are cleaned as part of the job, with the unit switched off and made safe first. If you are dealing with drain trays holding standing water and odours coming through the supply air, we can help, from drain trays, supply and extract fans and filter sections onwards.
For a building in or near Rowledge, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

When it’s something else
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- A system that’s undersized for the building
- Controls and BMS settings that run the unit
- Ductwork downstream of the unit, which is a separate clean
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think before booking.

Fixed quotes for AHU cleaning in Rowledge
A fixed price needs a few facts first. We look at:
- Site rules, permits and inductions
- Whether it’s a one-off visit or part of a schedule
- The times the site is available
- Where the site is and how we reach it
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 we need to know
When you contact us, it’s useful to have:
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
- Any previous report or certificate
Quotes are quick. Send a few details and photos, and we usually reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
How the visit works
Your staff do not 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. Photos of the system and how to reach it help us plan a visit to Rowledge.
- We look at the unit and the plant area during the survey.
- The area is protected and the unit made safe.
- Dirt and debris are removed from each section.
- We clean the coils and clear the tray and drain.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
Advice
Rowledge: your questions answered
Can a school’s ventilation in Rowledge be done out of term time?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Rowledge, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Can the work in Rowledge 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. When you call us on 0345 646 2711, or email photos, mention when the site is quiet.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Can you clean the ducts connected to the AHU?
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.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
When should our AHU next be cleaned?
That’s set by inspection, in line with TR19® Air. A hard-working unit, or one serving a hospital or care home, may need cleaning more often.
What should I send you?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
What do you clean inside the unit?
All the internal parts the air touches, from intake to discharge, including coils, fan and drain trays. You get a photo report showing each part before and after.

Local landmarks in Rowledge
Locally, jobs take us to businesses close to Underdown nature reserve, Weydon School and The Hare and Hounds pub and the streets around them. Rowledge’s nearest station is Bentley (Hampshire) station, roughly 2 miles west of the centre. A little further out are Chase Community Hospital (5.6 miles south) and Museum of Farnham (2.2 miles north). For a walk, there’s Beacon Hill and Farnham Heath.
What happens if it’s left?
Dirty coils and fans make the unit strain to move the same air. 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. Systems in rural buildings are often out of sight and out of mind.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

Managing agents and facilities teams in Rowledge
Keeping records across a portfolio is half the battle. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
