Your questions about AHU cleaning in Hobbs Cross

Is AHU cleaning available in Hobbs Cross?

Yes, Hobbs Cross is covered. To start, ring 0345 646 2711, or email photos with a few photos of the system.

Do you work overnight in Hobbs Cross?

Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Just give us a ring on 0345 646 2711 or email us with your opening times and we’ll plan around them.

What information do you need?

A short description and a few pictures, with the address and opening hours. If we need more, we’ll ask.

Which sectors do you work in?

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

Do you offer maintenance contracts?

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

What accreditations do you have?

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

How do you keep the site clean during the work?

Protection goes down first: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.

What do you clean inside the unit?

The main parts are the filters, coils, drain tray, fan and inside of the casing. The survey confirms what’s in your unit before we quote.

AHU cleaning in Hobbs Cross

The fan pushes every bit of air in the system, so dust on its blades and housing ends up in the airstream. We clean the fan section along with the rest of the unit, once the unit has been shut down and isolated. The work covers dampers and louvres, drain trays and heating and cooling coils, and common reasons people get in touch are rooms that smell stuffy when the system runs and plant that needs cleaning after a refit.

Work in a small place like Hobbs Cross starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.

The paperwork matters as much as the work. Each visit is written up with photos, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What staff can safely do

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.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

Aftercare tips

A little care between visits keeps the system in better shape. Our advice:

  • Keep inspection doors on the unit in good order
  • Flag stale or damp smells in the supply air
  • Watch for drips or damp patches near the plant
  • Make sure condensate is draining away

The ducts served by the unit may need attention too. Cleaning the unit and ducts together gives the best result, and we can survey both.

Don’t let leaves, litter or stored materials build up near the fresh air intake. What’s near the intake ends up in the unit.

What happens on the day

Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes from a few hours for a compact unit to a day or more for a large one. In a small place like Hobbs Cross, the journey is planned ahead and the visit arranged around the site’s hours.

  1. We agree a shutdown window that suits the building.
  2. Before cleaning, each section is photographed.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. We finish with the fan section and the drain tray.
  5. After pictures are taken and the certificate issued.

Before we arrive

  • Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
  • Move anything stored near the system
  • Tell us where we can park and unload

What a clean won’t put right

We will not sell you work that doesn’t address the problem, so here are the limits:

  • Mechanical faults with motors, belts or bearings
  • Dirty ducts beyond the unit itself
  • A system that is undersized for the building

If you are not sure, just give us a ring on 0345 646 2711 or email us and we will give you a straight answer.

Parts of the system we cover

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

How we price AHU cleaning

The quote reflects the site in front of us. We consider:

  • The size of the system
  • Whether it’s a one-off visit or part of a schedule
  • Site requirements such as sign-in and permits
  • Whether several sites go on one quote

Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.

Asking for a quote

To speed up the quote, please include:

  • Your opening hours and when the area is out of use
  • Close-ups of filters, grilles, hatches or access panels
  • Photos showing the whole system and its surroundings
  • The site address and the type of premises

Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.

Why it’s worth doing now in Hobbs Cross

A slimy drain tray only gets worse. Leave it and you risk overflows, leaks into the space below and odours carried round the building. Clearing it now is a much smaller job. Somewhere as small as Hobbs Cross, losing a kitchen or building to a fault is felt by everyone who uses it.

We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

When to call us in Hobbs Cross

Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.

These are the problems we see most often:

  • Rooms that smell stuffy when the system runs
  • Plant that has been serviced but not cleaned
  • Dust built up on fan impellers
  • Dust-coated heating and cooling coils

If you manage a school such as St John's Church of England Voluntary Controlled School, ventilation cleaning is best booked for the holidays.

What your quote should include

  • What records you’ll receive afterwards
  • What happens if part of the system cannot be accessed
  • Whether the work can be done while the site is closed
  • What’s included in the scope, part by part
