Why deal with it now?

AHU cleaning in South Street

Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. We’re often asked to deal with intake sections clogged with outdoor debris and plant that needs cleaning after a refit, on internal panels, dampers and louvres and drain trays.

For a building in or near South Street, 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.

Each visit ends with a written report and pictures, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods

Drain trays

A tray that does not drain becomes a pool of stagnant water in the airstream. We clean it and report anything about the tray or drain that needs fixing.

Filters

Dirty filters cut airflow and let dirt slip past their frames. We clean the frames and rails so the filters sit tight.

Ventilation in South Street buildings

At about 38 miles from central London, South Street sits well inside the area we cover. Evening, overnight and weekend visits are all possible. About 4.3 miles north-west of South Street is Princess Royal Hospital, the nearest hospital. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

If you manage a school such as Chailey School, ventilation cleaning is best booked for the holidays. Healthcare buildings such as Princess Royal Hospital, about 4.3 miles north-west, depend on their ventilation; if you manage a surgery, clinic or care home near South Street, yours matters too.

For landlords and multi-site operators

Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.

When something else is needed

We will not sell you work that does not address the problem, so these are the things it will not cover:

  • Coils that are corroded or leaking and need replacing
  • The supply and extract ducts, quoted separately
  • Ventilation that was badly designed in the first place

If in doubt, give us a ring on 0345 646 2711 or drop us a line and we’ll say what we think before you book.

What we work on in South Street

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

What staff can safely do

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.

Your questions about AHU cleaning in South Street

Do you clean school ventilation in South Street in the holidays?

Yes. Half-terms and the summer break are the natural time for school work. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of South Street. Tell us your holiday dates and we’ll book the visit for when the site is empty.

Can you work in South Street outside opening hours?

Yes, we can come after you close and finish before you open. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.

What information do you need?

Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then give us a ring on 0345 646 2711, or send details by email.

Are you insured?

Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.

What do you do with what you remove?

Waste is contained during the work and removed when we leave, including grease, debris and dirty water. We do not leave it behind.

Can you set up regular visits?

Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.

Which parts of an air handling unit do you clean?

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.

Will you repair the fan or motor?

Mechanical repairs to the unit are for your HVAC maintenance contractor. We’ll flag anything we notice during the clean.

The process

We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool first, and the area around the work is covered and protected. On site, it takes anything from half a day for one small unit to several shifts for a plant room full of them. A quick note on how to find the site and where to park makes a visit to South Street run smoothly.

  1. We survey the unit from pictures or on site and agree what’s included.
  2. With your site team, the unit is switched off and isolated, then the area around it protected.
  3. Filters, coils, fan section and casing are cleaned in turn.
  4. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

Before we arrive

  • Make sure someone can let us in and lock up afterwards
  • Tell us about site rules, permits or sign-in
  • Let us know about parking and loading

Ask for a quote

The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.

Advice

Aftercare tips

Aftercare is simple, and it helps at the next visit:

  • Do not ignore odours coming through the grilles
  • Plan the next inspection before the last report gets filed away
  • Keep the area around the fresh air intake clear
  • Report stiff or damaged access doors

If the ductwork hasn’t been cleaned, consider it next. Cleaning the unit and ducts together gives the best result, and we can quote for both.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.
