AHU cleaning in Kingston Stert

Landlords, agents and facilities managers

Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept on a regular cycle.

Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, ready to show insurers, fire officers or EHOs.

AHU cleaning in Kingston Stert

We clean the parts of the unit where dirt and moisture gather: the filter section, heating and cooling coils, drain trays, fan and casing. You get a TR19® certificate and a photo report showing the unit before and after. Common call-outs are for plant that has been serviced but not cleaned and odours coming through the supply air, across internal panels, drain trays and filter sections.

For a building in or near Kingston Stert, access is agreed in advance and the visit is planned around the journey.

The sign-off is always in writing: a written report, dated and illustrated with pictures, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Looking after it afterwards

After the visit, a few habits help the work last:

  • Flag stale or damp smells in the supply air
  • Watch for drips or damp patches near the plant
  • Clear leaves and litter away from the intake
  • Keep the certificate and photo report with the plant records

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.

Don’t let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.

Signs you need AHU cleaning in Kingston Stert

Filters catch most of the dust, but not all of it. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.

What we’re most often called out for:

  • Plant that has been serviced but not cleaned
  • Filters that are clogged or overdue
  • Dust-coated heating and cooling coils
  • Dust built up on fan impellers

Classrooms and halls at schools such as Aston Rowant Church of England Primary School are easiest to work in when pupils are away.

Your questions about AHU cleaning in Kingston Stert

Do you work in villages like Kingston Stert?

Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.

Can you work in Kingston Stert outside opening hours?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Let us know the hours you are closed and we’ll book within them.

Are you fully insured?

Yes. Duct Doctor is fully insured, and the details are available on request.

Do you offer maintenance contracts?

Yes, of course. Tell us what you have and how it’s used and we will propose a schedule with a fixed quote.

What do you do with what you remove?

We take it away at the end of the visit. While we work, it’s kept contained to keep the area clean.

How do you keep the site clean during the work?

Floors and surfaces near the work are sheeted before we start, and waste is contained as we go. At the end, the area is cleaned down.

What happens if you cannot reach some of it?

They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, along with a quote to put access in.

How much does AHU cleaning cost in Kingston Stert?

There’s no set price, as it depends on the job: the size of the system, its condition, access and when we can work. We fix the price before any work starts.

What the work involves, part by part

Fans and fan sections

Every bit of air passes the fan, so a dirty fan sends dirt downstream. We clean the impeller, housing and surrounding section.

Internal casing and panels

The inside walls and floor of the casing collect dust and debris. We clean each section from intake to discharge.

When something else is needed

We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

  • Leaking heating or cooling coils
  • Breakdowns that need a mechanical engineer
  • The supply and extract ducts, quoted separately

If in doubt, call us on 0345 646 2711, or email photos and we will say what we think before you book.

What we work on in Kingston Stert

  • Drain trays
  • Filter sections
  • Heating and cooling coils
  • Supply and extract fans
  • Dampers and louvres
  • Internal panels

How the visit works

The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes from a few hours for a compact unit to a day or more for a large one. If you can send photos, we can arrive in Kingston Stert knowing what to expect.

  1. We agree a shutdown window that suits the building.
  2. We take before pictures of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. The fan and drain tray are cleaned and the drain checked.
  5. We take after photos and issue the certificate and report.

How to prepare

  • Tell us the best time to work, such as after service or at a weekend
  • Tell us where we can park and unload
  • Mention any locked doors, roof access or ceiling voids

Getting a quote

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
