AHU cleaning across Aimes Green

AHU cleaning in Aimes Green, done properly

We clean air handling units for buildings in Aimes Green and across Essex, working to TR19® Air, in buildings such as offices, schools, healthcare sites and shops. Units are cleaned when the site can spare them, often evenings, overnight or weekends. We’re often asked to deal with stale or musty smells from the ventilation and units needing a clean before a new tenant or handover, on heating and cooling coils, drain trays and supply and extract fans.

Rural buildings with mechanical ventilation, such as care homes and country hotels, often keep their units in roof spaces or outbuildings, where filters and drain trays get forgotten.

Every visit ends with a written report and pictures, so you have a record of what was done and when. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

Between visits

Simple habits between visits make a real difference. Our advice:

  • Flag stale or damp smells in the supply air
  • Look at the condensate drain whenever the unit is serviced
  • Keep the certificate and photo report with the plant records
  • Change filters on schedule and log each change

The report suggests a date for the next inspection or clean, taking into account how dirty it was. Under TR19® Air the timing is set by inspection and risk, not a fixed calendar.

Have the unit inspected regularly, in line with the risk-based approach of TR19® Air instead of leaving it to guesswork.

What happens on the day

When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes half a day to a full day per unit, with large plant planned over several shifts. A quick note on how to find the site and where to park makes a visit to Aimes Green run smoothly.

  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. The fan and drain tray are cleaned and the drain checked.
  5. We take after pictures and issue the certificate and report.

Before we arrive

  • Make sure someone can let us in and lock up afterwards
  • Tell us about site rules, permits or sign-in
  • Find the previous report, if there is one

Getting a quote

The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Signs you need AHU cleaning in Aimes Green

Planned maintenance often covers belts, motors and filters but not cleaning. That means a unit can tick every service box and still be carrying years of dirt.

Look out for any of the following:

  • Plant that has been serviced but not cleaned
  • Debris and leaves in the fresh air intake
  • Filters that are clogged or overdue
  • Fan sections that haven’t been cleaned in years

Hospitals such as St. Margaret's Hospital (about 4.4 miles east) show how much a building can rely on clean ventilation, and smaller healthcare sites near Aimes Green are no different.

How to choose an extract cleaning contractor

Why act early in Aimes Green

Standing water in a drain tray does not clear itself. Left alone, it can overflow, leak into the plant area or ceiling below and spread smells through the system. Clearing it now is a much smaller job. In a small place like Aimes Green, a system that fails can take a site out of use.

Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered, and you’ll get one fixed quote.

What staff can safely do

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. Cleaning inside ducts and units is specialist work.

Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
