Guildford questions
Do you work overnight in Guildford?
Yes, out-of-hours work is a big part of what we do. The site is handed back ready to open. Your opening times are the first thing we ask for.
Is Guildford in your area for AHU cleaning?
Yes. We work across London and the South East, and Guildford is part of that. A fixed quote normally follows within one working day of the survey details.
What should I send you?
A short description and a few photos plus the address and your hours. We’ll ask for anything else we need.
How often do AHUs need cleaning?
TR19® Air takes a risk-based approach, so it depends on inspection rather than a fixed interval. Each report suggests when the unit should next be looked at.
Do you give a certificate after the clean?
Yes, both a certificate and a report with photos. It includes a recommended date for the next check.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can you set up regular visits?
Yes. We run scheduled maintenance contracts, with visits at the interval your system needs. Each report recommends when the next visit should be.
Which parts of an air handling unit do you clean?
Everything inside the unit that air passes over, from intake to discharge, including coils, fan and drain trays. The photo report shows each section before and after.
AHU cleaning for kitchens and businesses in Guildford
All the building’s air passes through the fan, so dirt on the impeller and housing gets spread around. We clean the fan section along with the rest of the unit, with the unit switched off and made safe first. The work covers heating and cooling coils, supply and extract fans and drain trays, and common reasons people get in touch are intake sections clogged with outdoor debris and plant that has been serviced but not cleaned.
Offices, schools and hotels in Guildford stay in use while their ventilation is cleaned, so we work zone by zone, out of hours where needed.
Every visit ends with a written report and photos, 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.
What AHU cleaning looks like in Guildford
Food Standards Agency data includes about 37 schools, colleges and universities, about 30 caring premises (care homes, nurseries and hospitals) and about 3 hotels, B&Bs and guest houses in and around Guildford, up to about a mile and a half out. Classrooms, bedrooms and care spaces are often served by ducted air, and that ductwork collects dust over time. Mount Alvernia Hospital is the nearest hospital, about 0.9 miles south-east of Guildford. Clean air matters most where people are unwell, and that is as true in a care home as in a hospital. Guildford is about 27 miles from central London, well within the area we cover across London and the South East. A survey and a fixed quote come first, then the visit at a time that suits you.
If you run a surgery, dental practice or care home near Guildford, clean ventilation matters as much to you as to a hospital like Mount Alvernia Hospital (about 0.9 miles south-east). Classrooms and halls at schools such as Sandfield Primary School are easiest to work in when pupils are away.

Part by part
Drain trays
Drain trays can rust and leak over time. Their condition goes into the report with photos so repairs can be planned.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Store the TR19 paperwork where auditors can find it
- Report musty smells from the vents right away
- Make sure the unit’s access doors open easily
- Make sure condensate is draining away
Once the clean is done, we send a TR19® certificate and a report with before and after photos. They belong in the plant or maintenance log.
Make sure access doors and panels on the unit open easily. If a section is hard to get into, it tends not to get checked.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Where a site in Guildford has more than one system, we can take them one at a time to keep the rest running.
- First we agree when the unit can be switched off, including evenings or weekends.
- Before cleaning, each section is photographed.
- Filters, coils and internal surfaces are cleaned from intake to discharge.
- We finish with the fan section and the drain tray.
- After pictures are taken and the certificate issued.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
- Mention any sign-in, permit or induction we need

Related advice
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Do you need AHU cleaning in Guildford?
Planned maintenance often covers belts, motors and filters but not cleaning. So a unit can be well maintained and still dirty.
What we’re most often called out for:
- Fan sections that haven’t been cleaned in years
- Plant that needs cleaning after a refit
- Dust-coated heating and cooling coils
- Drain trays holding standing water
For workplaces around London Road (Guildford) station with mechanical ventilation, cleaning can be done in the evening or at weekends.
What your quote should include
- Whether the price is fixed
- What happens if part of the system cannot be accessed
- Whether a survey comes first
- Whether the work can be done while the site is closed
What a clean will not put right
Some problems need a different service or another trade:
- Problems with the unit’s controls or sensors
- Ductwork downstream of the unit, which is a separate clean
- Airflow problems caused by the system’s design
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.

What affects the cost of AHU cleaning
The survey tells us what the work involves. We look at:
- When the work can happen, such as evenings, overnight or weekends
- What state the system is in
- Where the site is and how we reach it
- How easy every part is to reach
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before any work starts.
What we need to know
Photos let us diagnose from a distance. Try to include:
- Your opening hours and when the area is out of use
- A few general shots of the system
- Where the site is and what kind of site it is
- Any symptoms, from odd noises to smells or leaks
Here’s what helps us quote: where the site is, what it is and its opening hours, pictures of the system and any previous report or certificate. Once you have those, ring 0345 646 2711, or email photos.
