Your questions about AHU cleaning in Dummer

Can you come to Dummer after we close?

Yes, evening, overnight and weekend work is normal for us. It means the site in Dummer keeps running as normal. Just call us on 0345 646 2711, or send details by email with your opening times and we’ll plan around them.

Is Dummer within the area you cover?

Yes. Dummer is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.

What about areas you cannot get to?

The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, which we can install.

What does AHU cleaning cost?

The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote and we will usually reply within one working day.

Is there a survey before the work?

Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.

What types of premises do you cover?

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

How much notice should we give?

The more notice, the better, especially for out-of-hours work. We usually quote within one working day, and there’s a 24/7 line for emergencies.

Do you need to switch the unit off?

Yes. Cleaning needs the unit off and isolated, so we plan it for a time that suits the building.

AHU cleaning for kitchens and businesses in Dummer

Heating and cooling coils trap dust that gets past the filters. Dirt on the fins holds back air and makes the unit work harder to do the same job. Coils are cleaned carefully, with methods chosen so the fins are not flattened. Common call-outs are for odours coming through the supply air and dirty coils holding back the airflow, across drain trays, supply and extract fans and dampers and louvres.

For a building in or near Dummer, access is agreed in advance and the visit is planned around the journey.

Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What a clean will not put right

An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:

  • Faulty motors, drives or bearings
  • Ventilation that was badly designed in the first place
  • Damaged coils beyond cleaning

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

Where we work

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

Why it’s worth doing now in Dummer

Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, ready to show anyone who asks. Equipment tucked in a roof space or outbuilding near Dummer rarely gets looked at unless someone books it.

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 the price is fixed before any work starts.

How it works

The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes from a few hours for a compact unit to a day or more for a large one, and we clear up before we go. Rural roads and tight entrances are worth telling us about before a visit to Dummer.

  1. We survey the unit from photos or on site and agree what’s included.
  2. The unit is shut down with your site team and the area protected.
  3. Filters are dealt with as agreed, and the coils, fan and casing cleaned.
  4. We clean out the drain tray and make sure it drains.
  5. You get a TR19® certificate and a photo report.

Getting ready for the visit

  • Tell us the best time to work, such as after service or at a weekend
  • Mention any parking or loading restrictions
  • Dig out any earlier paperwork for the system

For landlords and multi-site operators

Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.

How the job changes from site to site

Heating and cooling coils

Dirt on a coil slows the air and makes it harder for the coil to heat or cool. A clean gets air moving through the coil properly again.

Fans and fan sections

The fan section is cleaned with the unit switched off and isolated with your site team.

Keeping the system healthy

No system stays clean for ever, but care slows the build-up. Our tips:

  • Report water on the plant room floor
  • Stick to the filter change plan
  • Keep inspection doors on the unit in good order
  • Clear leaves and litter away from the intake

If the ductwork hasn’t been cleaned, consider it next. A clean unit feeding dirty ducts only solves half the problem, and we can survey both.

Make the drain tray part of every maintenance visit. A drain that’s cleared early never gets to the slime stage.

What affects the quote in Dummer

Before we fix a price, we need to know a few things. We check:

  • How many systems or sites are involved
  • Site rules, permits and inductions
  • Travel, parking and unloading
  • The times the site is available

Every site is different, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all make a difference.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in touch, it helps to send:

  • Close-ups of filters, grilles, hatches or access panels
  • The site address and the type of premises
  • The paperwork from the last visit, if you have it
  • Problems your staff have spotted

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.
