AHU cleaning near South Stifford

AHU cleaning in South Stifford

If the units serving a building in South Stifford have only had filter changes for years, the coils, fan and casing can be carrying far more dirt than anyone has seen. A full clean deals with all of it. Common call-outs are for filters that are clogged or overdue and air handling units due a clean after building work, on drain trays, filter sections and dampers and louvres.

Around a place like South Stifford, ventilation systems tend to be in schools, surgeries, care homes and workplaces. Even a small system collects dust in its ducts and filters.

It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

How the visit works

We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. Tell us when your site near South Stifford is quiet and the visit will be booked for then.

  1. We look at the unit and the plant area during the survey.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Preparing for the visit

  • Name a contact who can let us in at the agreed time
  • Tell us about site rules, permits or sign-in
  • Clear loose items from the work area

Advice

What affects the cost of AHU cleaning

Your quote is based on your site. We consider:

  • Whether several sites go on one quote
  • Access, including roofs, risers and ceiling voids
  • A single visit or a regular plan
  • Working hours and out-of-hours timing

Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re unsure, ring 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

Helping us quote

A few details help us quote accurately. With your enquiry, please include:

  • Anything you’ve noticed, such as smells, noise, drips or poor airflow
  • Detail shots of panels, filters and grilles
  • Photos showing the whole system and its surroundings
  • The roof, plant room or outside wall the system runs to

Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Then call 0345 646 2711, or send details by email.

Why it’s worth doing now in South Stifford

A slimy drain tray only gets worse. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. Light use slows the build-up but does not stop it.

You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we’ll explain what it covers.

South Stifford: your questions answered

Can you work in South Stifford outside opening hours?

Yes, nights and weekends are routine for us. The work in South Stifford can fit around your hours. Tell us your opening hours when you ask for a quote.

Will you come out to South Stifford?

Yes, South Stifford is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.

How do you protect the area?

By covering it before any work starts. The work is kept contained and leave the area clean.

Do you offer emergency callouts?

Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

What should I send you?

The site address, the type of premises and your opening hours, along with a few pictures and any previous report.

Are you fully insured?

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

What do you do with what you remove?

It’s contained and taken away. Grease, debris and waste water are collected as the work goes on rather than letting it spread.

How often do AHUs need cleaning?

There’s no single answer; it comes down to the building and the unit. Regular inspection shows when it’s due, and the report recommends a next date.

Keeping the system healthy

Looking after the system between visits is straightforward, and it helps at the next visit:

  • Do not ignore odours coming through the grilles
  • Keep the certificate and photo report with the plant records
  • Make sure the unit’s access doors open easily
  • Note any water around the unit or leaks below it

Photos in the report cover the filters, coils, drain tray, fan and casing, along with anything we couldn’t reach. It also notes faults we spotted, such as damaged panels or a blocked drain.

Regular filter changes are the best protection an AHU has. Once filters clog, dirt starts getting past them.

Landlords, agents and facilities managers

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.

When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.

What we are called out for in South Stifford

Cooling coils create condensation, and that water has to go somewhere. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and that’s where slime and odours start.

Keep an eye out for any of the following:

  • Stale or musty smells from the ventilation
  • Units needing a clean before a new tenant or handover
  • Plant that has been serviced but not cleaned
  • Dirty filters cutting the airflow

If you manage shops or offices close to Chafford Hundred station, a TR19® Air inspection shows whether the ductwork needs cleaning.

Questions to ask before booking

  • How VAT is shown on the quote
  • What paperwork you get at the end
  • Whether the figure could change on the day
  • Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
