Honest limits

AHU cleaning can’t fix everything, and we’ll tell you before work begins. It won’t put right:

  • Breakdowns that need a mechanical engineer
  • Leaking heating or cooling coils
  • Ventilation that was badly designed in the first place

Not sure which it is? You can ring 0345 646 2711 or use the quote form and we will tell you honestly.

Where we work

  • Supply and extract fans

  • Dampers and louvres

How we handle AHU cleaning in Mayfair

A cooling coil drips condensate into a tray that should drain away. If the outlet blocks, standing water and slime build up, in the airstream that feeds the building. Cleaning and clearing it is a key part of the job. The work covers heating and cooling coils, dampers and louvres and drain trays, and the jobs we see most are air handling units never cleaned inside and air handling units with blocked filters.

Many London buildings have had their ventilation extended and altered through several fit-outs, with old runs left behind that are hard to reach. An inspection first shows where cleaning is needed in a building in Mayfair.

Every visit ends with a written report and photos, 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.

Do you need AHU cleaning in Mayfair?

Air handling units are usually tucked away on roofs, in plant rooms or above ceilings and are rarely seen by anyone but maintenance staff. It’s easy for a long time to go by without anyone opening the panels.

Clients typically contact us when they notice one of these:

  • Drain trays holding standing water
  • Rooms that smell stuffy when the system runs
  • Dirty coils holding back the airflow
  • Filters that are clogged or overdue

If you run a surgery, dental practice or care home near Mayfair, clean ventilation matters as much to you as to a hospital like London Eye Hospital (about 0.5 miles north).

What your quote should include

  • Proof of insurance
  • If the quote is a fixed price or an estimate
  • Whether inaccessible sections are listed on the report
  • Exactly which parts of the system are covered

Questions to ask before you book

What affects the quote in Mayfair

We quote each job individually. This is what makes a difference:

  • What state the system is in
  • A single visit or a regular plan
  • How many systems or sites are involved
  • The size of the system

Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, phone us on 0345 646 2711 or drop us a line and we’ll give you an honest view and a fixed quote.

What we need to know

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

  • Photos showing the whole system and its surroundings
  • Where the plant sits or the system leaves the building, such as a roof or outside wall
  • The site address and the type of premises
  • Any symptoms, from odd noises to smells or leaks

Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before we start.

Why deal with it now?

When the unit is clean, less dirt reaches the ducts, so the ducts and grilles stay cleaner between cleans. It also means the next inspection has less to find. A building in Mayfair may have flats or offices above and alongside, and a fault in the system can affect them too.

Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.

How the visit works

Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Afterwards, the area is left tidy and the written report follows. A name and number for whoever controls access to the building in Mayfair saves time on the night.

  1. First we agree when the unit can be switched off, including evenings or weekends.
  2. We take before photos of each section of the unit.
  3. We work through the unit from the intake to the outlet.
  4. We finish with the fan section and the drain tray.
  5. We take after pictures and issue the certificate and report.

Before we arrive

  • Let us know about permits to work or site inductions
  • Name a contact who can let us in at the agreed time
  • Mention any locked doors, roof access or ceiling voids

Get a fixed quote

We don’t publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, and then give you a fixed quote. To start, ring 0345 646 2711 or use the quote form.

Advice

What the work involves, part by part

Drain trays

Older trays can corrode and start leaking. Their condition goes into the report with photos so you can decide on any repairs.

Filters

What’s on the filters is a good clue to what’s further in. We photograph them for the report.

Common questions in Mayfair

How do you handle parking and loading in Mayfair?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.

Can you come to Mayfair after we close?

Yes, out-of-hours work is a big part of what we do. The work in Mayfair can fit around your hours. Let us know the hours you’re closed and we’ll book within them.

How much notice do you need?

It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.

Can you price the work without visiting?

In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.

Do you repair air handling units?

Motors, belts, controls and coils that need repair are a job for your maintenance contractor. We’ll flag anything we notice during the clean.

Do you work with multi-site operators?

Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Every site has its own report.

How much does AHU cleaning cost in Mayfair?

The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, usually ready within one working day.

Are you fully insured?

Yes. We carry full insurance, and we’ve been trading since 2009.

Managing agents and facilities teams in Mayfair

For anyone managing more than one site, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so each one has its own record.

From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.

Ventilation in Mayfair buildings

The FSA’s food hygiene register lists about 88 schools, colleges and universities, about 33 hospitals, care homes and childcare premises and about 286 hotels and guest houses with registered kitchens or food service within 1.5 miles or so of the middle of Mayfair. Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. Ventilation cleaning in London buildings is normally planned for evenings or weekends. London Eye Hospital is the nearest hospital, about 0.5 miles north of Mayfair. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale.

Workplaces around Bond Street station with an air handling unit need the filters, coils and drain tray looked at, as well as the ducts. Classrooms and halls at schools such as LITE Regal International School are easiest to work in when pupils are away.
