AHU cleaning for sites in Gomshall

AHU cleaning for kitchens and businesses in Gomshall

Our AHU cleaning covers sites in Gomshall and the rest of Surrey, in buildings such as offices, schools, healthcare sites and shops. The work is timed around when the system can be switched off, including evenings, nights and weekends. Typical jobs include air handling units with blocked filters and air handling units never cleaned inside, across supply and extract fans, dampers and louvres and internal panels.

In a village or hamlet like Gomshall, few buildings have mechanical ventilation, but those that do need it inspected and cleaned like any other.

Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What a clean will not put right

To be straight with you, some problems need a different fix:

  • Airflow problems caused by the system’s design
  • Faulty motors, drives or bearings
  • Controls and BMS settings that run the unit

Not sure which it is? You can call us on 0345 646 2711 or drop us a line and we’ll tell you honestly before you book.

What we work on in Gomshall

  • Heating and cooling coils

Fixed quotes for AHU cleaning in Gomshall

Sites vary more than people expect. The main factors:

  • The times the site is available
  • Site requirements such as sign-in and permits
  • Where the site is and how we reach it
  • A single visit or a regular plan

The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before any work starts, so you know where you stand.

Asking for a quote

Photos let us diagnose from a distance. Try to include:

  • Where the site is and what kind of site it is
  • Your last certificate, test record or report
  • Any access panels or hatches you can see
  • The roof, plant room or outside wall the system runs to

To get a fixed quote, give us a ring on 0345 646 2711 or email us and tell us the type of site, your opening hours and roughly what the system looks like. A few pictures and your last certificate or report help a lot. We usually come back within one working day.

Staff cleaning versus specialist work

Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.

Aftercare tips

Results last longer with the right care. Here’s what we suggest:

  • File each AHU report in the maintenance log
  • Report water on the plant room floor
  • Clear leaves and litter away from the intake
  • Diary the inspection date recommended in the report

Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.

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.

Gomshall buildings and their air

Gomshall, about 25 miles from central London, is within our usual area. The visit is fixed around your opening hours, not ours. For Gomshall, the closest hospital is St. Luke’s Hospital, roughly 4.9 miles west. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.

If you run an office near Gomshall station, its supply ductwork can gather dust for years before anyone looks inside. Classrooms and halls at schools such as Shere CofE Aided Infant School are easiest to work in when pupils are away. St. Luke’s Hospital, about 4.9 miles west, is the nearest hospital to Gomshall, and healthcare sites of every size need their supply air kept clean.

Questions from Gomshall

Will you come out to Gomshall?

Yes, we work in villages as well as towns, and Gomshall is covered. Just mention lanes, gates or anything else about the site when you book.

Do you do school ventilation cleaning in Gomshall in the summer holidays?

Yes, holiday work suits schools best. With about 2 schools and colleges on the FSA’s register within roughly a mile and a half of Gomshall, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or email us with your term dates and we will plan around them.

What is TR19?

BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.

What do you do to protect the area?

We cover floors and nearby surfaces with sheeting before work begins, and anything we remove is contained. At the end, the area is cleaned down.

Which kinds of sites do you work on?

Restaurants and pubs, hotels, schools and colleges, hospitals and care homes, offices and retail, as well as food production and leisure sites.

How long does an AHU clean take?

Typically the clean takes from a few hours for a compact unit to a day or more for a large one. We plan the shutdown around that, including evenings or weekends.

Which accreditations do you hold?

We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

When should our AHU next be cleaned?

It depends on the unit, the filters and how the building is used. Inspection tells you when cleaning is needed, and the report recommends a next date.

Managing agents and facilities teams in Gomshall

Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.

Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.

Different parts, different methods

Internal casing and panels

Loose or damaged linings inside a unit can break up into the airstream. We note any we find in the report.

Fans and fan sections

Dust on a fan impeller adds weight and wear. A clean fan runs more smoothly.

What happens on the day

Each visit runs to the same pattern: sheeting and protection first, make the system safe, do the work, clear away and hand over the paperwork. On site, the work takes one overnight shift for many single units, with bigger plant phased. Somewhere as small as Gomshall, the date and timings are agreed with you well before the day.

  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. Coils and trays are cleaned and the condensate drain cleared.
  5. We close every panel, hand the unit back and send the report and certificate.

Preparing for the visit

  • Agree a time when the area can be out of use
  • Mention any sign-in, permit or induction we need
  • Allow time for equipment near the work to be turned off and cool down
