Aftercare tips

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

  • Keep inspection doors on the unit in good order
  • File each AHU report in the maintenance log
  • Don’t ignore odours coming through the grilles
  • Clear leaves and litter away from the intake

When we have closed the unit up, it can be restarted with your site team. Keep an eye on the condensate drain over the next few days to make sure it stays clear.

Keep the area around the intake clear. What’s near the intake ends up in the unit.

How we handle AHU cleaning in Fenn Street

Every supply and extract system relies on the air handling unit at its centre: air is pulled in, filtered, conditioned and sent out through the ducts. Anything that collects inside the unit can end up in the rooms it serves, so cleaning the unit matters as much as cleaning the ducts. Common call-outs are for units that have only ever had filter changes and filters that are clogged or overdue, on heating and cooling coils, drain trays and internal panels.

In a village or hamlet like Fenn Street, few buildings have mechanical ventilation, but where it’s fitted, it needs the same inspection and cleaning as anywhere.

We are CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Fixed quotes for AHU cleaning in Fenn Street

The diagnosis comes before the price. The main factors are:

  • Working hours and out-of-hours timing
  • How easy every part is to reach
  • Site rules, permits and inductions
  • The number of sites or systems

When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.

What to send for a quote

There’s no need for technical detail. Just send:

  • The site address and the type of premises
  • Any symptoms, from odd noises to smells or leaks
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • Any access panels or hatches you can see

We do not publish a price list, because no two systems are the same. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711, or email photos.

Signs you need AHU cleaning in Fenn Street

Filters that are not changed or cleaned on time clog up, cutting airflow and sometimes letting dirty air bypass them altogether. Then the rest of the unit takes the load.

What we are most often called out for:

  • Units that have only ever had filter changes
  • Plant that needs cleaning after a refit
  • Dust-coated heating and cooling coils
  • Debris and leaves in the fresh air intake

School buildings such as High Halstow Primary Academy are normally done in the holidays, so classrooms are not disturbed.

Questions to ask before you book

  • Whether VAT is included
  • Whether the work can be done while the site is closed
  • Whether the quote is based on a survey or pictures
  • Whether a written report and pictures are included

  • Filter sections

What we do, step by step

The visit has three parts: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. Most of the time goes on the work itself, which takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Fenn Street, the date and timings are agreed with you well before the day.

  1. The survey covers the unit, its access and how it can be shut down.
  2. We sheet the area and the unit is isolated.
  3. Each section is cleaned of dust, debris and slime.
  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.

Getting ready for the visit

  • Plan for cooking equipment or plant to be off before we arrive
  • Mention any locked doors, roof access or ceiling voids
  • Tell us about site rules, permits or sign-in

Getting a quote

Quotes are quick. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

Advice

Multi-site and managed buildings

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.

Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.

Questions from Fenn Street

Is Fenn Street in your area for AHU cleaning?

Yes. We work across London and the South East, and Fenn Street is part of that. Get in touch with the details and we will arrange a survey.

Do you cover smaller places like Fenn Street?

Yes, we work in villages as well as towns, and Fenn Street is covered. A survey first, from photos or a visit, means we arrive with the right kit.

Do you clean the ductwork as well?

Yes. We reach the ducts through access panels, with anything inaccessible recorded, and new panels can be fitted.

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 often should an air handling unit 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.

Do you work with multi-site operators?

Yes. Send the list of sites and the work at each and you’ll get one fixed quote.

Is there a report after cleaning?

Yes, both a certificate and a report with photos. It includes a recommended date for the next check.

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.

How the job changes from site to site

Rooftop and plant room units

Units on roofs and in plant rooms can be awkward to reach. We plan safe access as part of the survey, before we quote.

Fans and fan sections

The fan section is cleaned with the unit switched off and isolated in agreement with the site.
