Looking after it afterwards

Simple habits between visits make a real difference. We recommend:

  • Change filters on schedule and log each change
  • Note any water around the unit or leaks below it
  • File each AHU report in the maintenance log
  • Book the next check in line with the report

The report shows each section of the unit before and after, along with anything we couldn’t reach. Any defects we noticed, like a leaking tray or damaged lining, are listed.

Change or clean filters on time. Overloaded filters let more dirt through to the coils and fan.

About our AHU cleaning in Hamstead

Drain trays under cooling coils are meant to empty. 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 drain trays, filter sections and supply and extract fans, and the jobs we see most are dust-coated heating and cooling coils and plant that has been serviced but not cleaned.

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 photos, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What AHU cleaning can’t fix

We’d rather tell you now than book work that won’t help, so these are the things it will not cover:

  • The supply and extract ducts, quoted separately
  • Airflow problems caused by the system’s design
  • Building management system faults

If you’re not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer.

Parts of the system we cover

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

What affects the cost of AHU cleaning

A fixed price needs a few facts first. We look at:

  • Whether we need access equipment or extra panels
  • The condition we find in the survey
  • Parking and loading at the site
  • A single visit or a regular plan

Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

Helping us quote

When you contact us, these details help:

  • The roof, plant room or outside wall the system runs to
  • When the site is open and when it’s quiet
  • The site address and the type of premises
  • Any symptoms, from odd noises to smells or leaks

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.

Your questions about AHU cleaning in Hamstead

Will you come out to Hamstead?

Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.

Can you come to Hamstead after we close?

Yes, out-of-hours work is a big part of what we do. It means the site in Hamstead keeps running as normal. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.

How much does AHU cleaning cost?

Size, condition, access and working hours all affect the cost. Call for a fixed quote, usually ready within one working day.

Do you have a 24/7 line?

Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we’ll advise on what to do next.

Are you insured?

Yes. Duct Doctor is fully insured, and the details are available on request.

What is TR19?

TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.

How long does an AHU clean take?

Expect it to take a single shift for a typical unit, longer for large or heavily soiled ones. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.

Do you look at the system first?

Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.

Different parts, different methods

Filters

Every AHU relies on its filters to catch dust before it reaches the coils. As part of the clean, filters are checked and cleaned or replaced as agreed, and clean the filter housing.

Rooftop and plant room units

Smaller units in ceiling voids are part of the work as well. We protect the area below before opening them.

How it works

We are used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes half a day to a full day per unit, with large plant planned over several shifts. The timing of a visit to Hamstead is set by you, and the travel is our side of the planning.

  1. We start with a survey of the unit and a fixed quote for the work.
  2. We arrange the shutdown with your staff and sheet the area.
  3. We clean or change the filters as agreed, then clean the coils, fan and internal panels.
  4. We clean out the drain tray and make sure it drains.
  5. We close up the unit and send the certificate and before and after pictures.

How to prepare

  • Make sure someone can let us in and lock up afterwards
  • Let us know when the site is closed or quiet
  • Find the previous report, if there is one

Getting a quote

Some systems can be priced from pictures; 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 work begins.

Managing agents and facilities teams in Hamstead

Keeping records across a portfolio is half the battle. Each visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.

Why deal with it now?

Tenants, auditors and owners may want proof that the air handling plant is kept clean. Our certificate and photo report give you clear evidence, for audits, tenants or your own peace of mind. If the system at a site near Hamstead fails, there may be nowhere nearby to move to.

What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
