About our AHU cleaning in Comp

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. We clean coils with methods suited to their condition, taking care not to damage the fins. If you are dealing with plant that needs cleaning after a refit and dust-coated heating and cooling coils, we can help.

In rural areas, ventilation units are often in roof voids or outbuildings, where filters and drain trays get forgotten.

The paperwork matters as much as the work. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

How the visit works

The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes half a day to a full day per unit, with large plant planned over several shifts, and we clear up before we go. Seeing the system in pictures first means the trip to Comp can be planned properly.

  1. The survey covers the unit, its access and how it can be shut down.
  2. The area is protected and the unit made safe.
  3. Dirt and debris are removed from each section.
  4. We clean the coils and clear the tray and drain.
  5. We close every panel, hand the unit back and send the report and certificate.

Before we arrive

  • Agree a time when the area can be out of use
  • Plan for cooking equipment or plant to be off before we arrive
  • Find the previous report, if there is one

Every quote begins with a look at the system, from your pictures and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before any work starts.

What a clean will not put right

We will not sell you work that doesn’t address the problem, so these are the things it will not cover:

  • Ventilation that was badly designed in the first place
  • Mechanical faults with motors, belts or bearings
  • Building management system faults

If in doubt, give us a ring on 0345 646 2711, or email photos and we will say what we think before you book.

Parts of the system we cover

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

Fixed quotes for AHU cleaning in Comp

The survey tells us what the work involves. We look at:

  • The condition we find in the survey
  • A single visit or a regular plan
  • Access, including roofs, risers and ceiling voids
  • Working hours and out-of-hours timing

The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before work begins.

What to send for a quote

We can often survey from photos. The most useful are:

  • The paperwork from the last visit, if you have it
  • The roof, plant room or outside wall the system runs to
  • The site address and the type of premises
  • The times we could work without disrupting the site

We don’t publish a price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, call 0345 646 2711, or send details by email.

What the work involves, part by part

Heating and cooling coils

Because cooling coils run wet, the dirt on them tends to cling. The coil and its drain tray are cleaned as one job.

Internal casing and panels

Dust settles on every internal surface of the unit. We clean each section from intake to discharge.

Multi-site and managed buildings

Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.

The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.

FAQs for Comp

Do you clean school ventilation in Comp in the holidays?

Yes, out-of-term visits are normal for schools. With about 5 schools and colleges on the FSA’s register within roughly a mile and a half of Comp, it pays to plan holiday dates ahead. Just call us on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.

Can you work in Comp outside opening hours?

Yes, we can come after you close and finish before you open. The work in Comp can fit around your hours. Your opening times are the first thing we ask for.

How much does AHU cleaning cost?

The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll typically reply within one working day.

What happens to the waste?

We take it away at the end of the visit. While we work, it’s kept contained so the area stays clean.

Will we get paperwork for the AHU clean?

Yes. Every clean comes with a TR19® certificate and a photo report. They’re worth keeping with the plant records.

Do you need to switch the unit off?

Yes, while the clean is under way. Out-of-hours work is available so the building isn’t left without ventilation when it’s busy.

Can one contract cover all our sites?

Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.

Do you have a 24/7 line?

Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.

Why act early in Comp

Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, which is why the unit and the ducts are best cleaned together. In a place like Comp, ductwork and fans are easy to forget until something goes wrong.

Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at, and you will get one fixed quote.

Keeping the system healthy

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

  • Plan the next inspection before the last report gets filed away
  • Look at the condensate drain whenever the unit is serviced
  • Keep inspection doors on the unit in good order
  • Clear leaves and litter away from the intake

Restart the unit with your site team or maintenance contractor once we have finished. Keep an eye on the condensate drain over the next few days to make sure it stays clear.

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