Surrey · Air handling unit cleaning
Grayswood AHU cleaning
Air handling unit cleaning for businesses, landlords and public buildings in Grayswood. CHAS, SafeContractor and ISO 9001, and fully insured.
- Plant that needs cleaning after a refit
- Intake sections clogged with outdoor debris
- Units that have only ever had filter changes
When to call us in Grayswood
No filter stops everything. The fine dust that passes the filters lands on the coils, the fan and the internal panels, a little more each month.
If you notice any of these, it’s worth a diagnosis:
- Dust built up on fan impellers
- Blocked condensate drains and slimy trays
- Dirty filters cutting the airflow
- Air handling units never cleaned inside
School buildings such as Grayswood Church of England (Aided) Primary School are usually done in the holidays, so classrooms aren’t disturbed.

AHU cleaning for kitchens and businesses in Grayswood
An AHU clean is a thorough examination and treatment of the unit. Every section is opened, cleaned and photographed, so the report shows exactly what was done. The work covers drain trays, filter sections and internal panels, and the jobs we see most are rooms that smell stuffy when the system runs and dirty fans and fan housings.
For a building in or near Grayswood, access is agreed in advance and the visit is planned around the journey.
The report is your system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Grayswood buildings and their air
Going by the FSA’s register, there are about 3 care, childcare and hospital premises serving food in Grayswood and the streets around it, up to about 1.5 miles out. Where buildings like these have air handling units, filters, coils and drain trays need regular attention. Grayswood, about 37 miles from central London, is within our usual area. A survey and a fixed quote come first, then the visit at a time that suits you. The nearest hospital to Grayswood is Haslemere and District Hospital, about 1.2 miles south-west.

The visit itself takes from a few hours for a compact unit to a day or more for a large one. A quick note on how to find the site and where to park makes a visit to Grayswood run smoothly.
- We look at the unit and the plant area during the survey.
- We sheet the area and the unit is isolated.
- Dirt and debris are removed from each section.
- Coils and trays are cleaned and the condensate drain cleared.
- We close every panel, hand the unit back and send the report and certificate.
Before we arrive
- Mention any sign-in, permit or induction we need
- Clear loose items from the work area
- Make sure someone can let us in and lock up afterwards

Honest limits
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Controls and BMS settings that run the unit
- Faulty motors, drives or bearings
- A system that is undersized for the building
If you are not sure, just call us on 0345 646 2711 or use the quote form and we’ll give you a straight answer before booking.
What the work covers
- Supply and extract fans
- Drain trays
- Filter sections
- Heating and cooling coils
- Internal panels
- Dampers and louvres
Different parts, different methods
Internal casing and panels
Damaged internal linings or loose panels can shed material into the air. Anything like that is recorded with photos.
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 the housing around them is cleaned too.
How we price AHU cleaning
Sites vary more than people expect. What affects the quote:
- Working hours and out-of-hours timing
- How big the system is
- How many systems or sites are involved
- Whether it’s a one-off visit or part of a schedule
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
What we need to know
When you call or email, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- Your opening hours and when the area is out of use
Here’s what helps us quote: the address, the type of site and when it’s open, a few photos and any previous report or certificate. Once you have those, phone us on 0345 646 2711 or use the quote form.
Your questions about AHU cleaning in Grayswood
Can you get to a site in Grayswood?
Yes, we work in villages as well as towns, and Grayswood is covered. Photos of the system and directions to the site help us plan the visit.
Do you offer AHU cleaning in Grayswood?
Yes. We work across London and the South East, and Grayswood is part of that. You can ring 0345 646 2711 or use the quote form and tell us what needs doing.
How long will the unit be out of action?
It takes from a few hours for a compact unit to a day or more for a large one. The unit’s size and condition make the biggest difference, and the quote will give you a clear idea.
Do you work evenings or weekends?
Yes. We work evenings, overnight and weekends, so the building keeps running in the day.
Will the ventilation be off while you clean?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
Can you quote from pictures?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we cannot see enough, we arrange a survey.
Do you repair air handling units?
The clean includes noting faults, but repairs sit with your maintenance contractor, with pictures where it helps.

What else we do in Grayswood
What staff can safely do
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Why deal with it now?
Stuffy rooms and stale smells in a building in Grayswood can sometimes be traced back to the AHU. A clean tackles the source instead of masking it. Systems in rural buildings are often out of sight and out of mind.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, call us on 0345 646 2711, or email photos and we will give you an honest view and a fixed quote.
