AHU cleaning in Compton
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. Common call-outs are for dust built up on fan impellers and plant that needs cleaning after a refit, across dampers and louvres, supply and extract fans and filter sections.
In a village or hamlet like Compton, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.
Duct Doctor has been trading since 2009, as 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.

Landlords, agents and facilities managers
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.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.

Compton buildings and their air
Compton, about 30 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. Royal Surrey County Hospital is the nearest hospital, about 2 miles north-east of Compton. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.
For schools like Loseley Fields Primary School, the holidays are the usual time to inspect and clean ventilation.

Signs you need AHU cleaning in Compton
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. It’s easy for a long time to go by without anyone opening the panels.
If you notice any of these, it’s worth a diagnosis:
- Coils clogged with dust and debris
- Debris and leaves in the fresh air intake
- Condensate trays that will not empty
- Fan sections that haven’t been cleaned in years
Royal Surrey County Hospital, about 2 miles north-east, is the nearest hospital to Compton, and healthcare sites of every size need their supply air kept clean.
What your quote should include
- Whether the price is fixed
- Exactly which parts of the system are covered
- Whether a survey comes first
- Proof of accreditation you can verify
Why it’s worth doing now in Compton
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 clean on your terms beats a breakdown on nobody’s. Equipment tucked in a roof space or outbuilding near Compton rarely gets looked at unless someone books it.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.
Why us?
- In business since 2009
- Fixed quotes, typically within one working day
- Out-of-hours work and a 24/7 emergency line
- We diagnose before we treat

What AHU cleaning can’t fix
Not every problem is solved by AHU cleaning, and we will tell you before we start. It won’t put right:
- The supply and extract ducts, quoted separately
- Mechanical faults with motors, belts or bearings
- A system that is undersized for the building
If in doubt, phone us on 0345 646 2711, or send details by email and we’ll say what we think before you book.
Parts of the system we cover
- Heating and cooling coils
- Drain trays
- Filter sections
- Internal panels

Compton: your questions answered
Do you work in villages like Compton?
Yes, we work in villages as well as towns, and Compton is covered. A survey first, from pictures or a visit, means we arrive with the right kit.
Can you come to Compton after we close?
Yes. We work evenings, overnight and at weekends. It means the site in Compton keeps running as normal. When you give us a ring on 0345 646 2711 or drop us a line, mention when the site is quiet.
How often do AHUs need cleaning?
It depends on the unit, the filters and how the building is used. Regular inspection shows when it’s due, and we’ll suggest an interval after the first clean.
What should I send you?
Only a few details: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply give us a ring on 0345 646 2711, or email photos.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
Do you work with multi-site operators?
Yes. Send the list of sites and the work at each and we’ll quote them together.
How we price AHU cleaning
We quote each job individually. This is what makes a difference:
- Parking and loading at the site
- A single visit or a regular plan
- Whether several sites go on one quote
- The times the site is available
One small site or a whole estate, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before any work starts.
What we need to know
You don’t need the technical terms. Just send:
- Where the site is and what kind of site it is
- Any previous report or certificate
- Wide photos of the system and the area around it
- How we’d reach plant on a roof or in a plant room
If you need AHU cleaning in Compton, call us on 0345 646 2711 or use the quote form. Let us know the site type and the opening hours, plus pictures or the previous report if they’re to hand. We usually send a fixed quote within one working day.
How the job changes from site to site
Filters
Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
