AHU cleaning for kitchens and businesses in Brimsdown

Coils are where a lot of the dirt ends up. Dirt on the fins holds back air and makes the unit work harder to do the same job. We clean coils with methods suited to their condition, taking care not to damage the fins. The work covers heating and cooling coils, drain trays and internal panels, and people most often call us about blocked condensate drains and slimy trays and rooms that smell stuffy when the system runs.

Across London, offices, hotels, schools and healthcare buildings rely on mechanical ventilation, much of it supplied through air handling units on roofs or in basements. In a building in Brimsdown, dust and debris build up in the units and ductwork over time.

Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Brimsdown questions

Can parking be tricky for a job in Brimsdown?

We plan it in advance, so let us know about loading bays, permits and access rules at the building. If the building has a loading slot system, we will book into it.

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

Yes, out-of-term visits are normal for schools. Food Standards Agency records list about 35 schools, colleges and universities with registered kitchens within about a mile and a half of Brimsdown. Send us your term dates when you phone us on 0345 646 2711 or drop us a line, and we will fit the work in.

Do you cover Brimsdown?

Yes. Our area takes in London and the counties of South East England, Brimsdown included.

Can you quote from photos?

In many cases, yes. With good pictures, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.

Can one contract cover all our sites?

Yes. Send the list of sites and the work at each and we’ll quote them together.

Do you repair air handling units?

We clean the unit and flag faults rather than repair them, with the details in the report.

Do you survey before quoting?

Yes. Every job is surveyed first, either from pictures and details you send or on a site visit. Then you get a fixed quote.

Will we get paperwork for the AHU clean?

Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.

How it works

There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, which takes one overnight shift for many single units, with bigger plant phased. A name and number for whoever controls access to the building in Brimsdown saves time on the night.

  1. We agree a shutdown window that suits the building.
  2. We take before photos of each section of the unit.
  3. Filters, coils and internal surfaces are cleaned from intake to discharge.
  4. The fan and drain tray are cleaned and the drain checked.
  5. After pictures are taken and the certificate issued.

Getting ready for the visit

  • Name a contact who can let us in at the agreed time
  • Tell us about site rules, permits or sign-in
  • Clear loose items from the work area

Rooftop and plant room units

Units on roofs and in plant rooms can be awkward to reach. Access is planned during the survey, before we quote.

Drain trays

The drain tray collects water from the cooling coil. We clear standing water, clean out slime and check the outlet is draining.

Many buildings of this kind have supply and extract ductwork that gathers dust and needs inspecting. For Brimsdown, the closest hospital is St Michaels Hospital, roughly 2.5 miles west. If you run a surgery, clinic or care home, your ventilation deserves the same care as a hospital’s, on a smaller scale. In London, ventilation plant is often on the roof or below ground, so the work is typically done out of hours.

Why act early in Brimsdown

A clogged coil or dirty fan makes the unit work harder for the same airflow. That means more wear on the motor and rooms that feel less fresh, and a planned clean is far less disruptive than a breakdown. Every month a London system goes without attention adds to what has to be done later.

Working hours, access and the scale of the site all affect the cost. Each of those is built into the quote, and the price is fixed before we start.

In-house cleaning or a specialist?

When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.

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

What affects the cost of AHU cleaning

  • The condition we find in the survey
  • Access, including roofs, risers and ceiling voids
  • When the work can happen, such as evenings, overnight or weekends
  • The number of sites or systems

What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.
