AHU cleaning in Mayes Green
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 have drain trays holding standing water and debris and leaves in the fresh air intake, we can put it right.
In rural areas, ventilation units are often in roof voids or outbuildings, which makes them easy to overlook.
We’re CHAS and SafeContractor accredited, we hold ISO 9001 and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Common problems we fix in Mayes Green
Most units live out of sight on roofs, in plant rooms or in ceiling voids, so they’re easy to forget about. Months can pass without anyone looking inside.
Keep an eye out for these warning signs:
- Plant that has been serviced but not cleaned
- Drain trays holding standing water
- Dirty coils holding back the airflow
- Rooms that smell stuffy when the system runs
Horsham Hospital, about 6 miles south-east, is the nearest hospital to Mayes Green, and healthcare sites of every size need their supply air kept clean.

What affects the quote in Mayes Green
A fixed price needs a few facts first. We check:
- The times the site is available
- The scale of the work
- How easy every part is to reach
- How many systems or sites are involved
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You will have a fixed price before work begins.
What to send for a quote
A few details help us quote accurately. With your enquiry, please include:
- The paperwork from the last visit, if you have it
- The times we could work without disrupting the site
- Detail shots of panels, filters and grilles
- Where the site is and what kind of site it is
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before any work starts.
Aftercare tips
Results last longer with the right care. We suggest:
- Flag stale or damp smells in the supply air
- Store the TR19 paperwork where auditors can find it
- Report stiff or damaged access doors
- Change filters on schedule and log each change
Once the clean is done, we send a TR19® certificate and a report with before and after photos. Keep both with the building’s maintenance records.
Keep the area around the intake clear. What’s near the intake ends up in the unit.
Mayes Green: your questions answered
Do you work at weekends in Mayes Green?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in Mayes Green needn’t be disturbed. Let us know the hours you are closed and we’ll book within them.
Do you cover smaller places like Mayes Green?
Yes, we work in villages as well as towns, and Mayes Green is covered. Photos of the system and directions to the site help us plan the visit.
Do you give a certificate after the clean?
Yes. You get a TR19® certificate plus before and after photos. Keep them in the maintenance log.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
What do you need from me for a quote?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call us on 0345 646 2711 or send us an email.
Will the ventilation be off while you clean?
Yes, while the clean is under way. We can work evenings, overnight or at weekends so the building isn’t left without ventilation when it’s busy.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
Why act early in Mayes Green
Dirt left in an air handling unit does not stay in the unit. It moves on into the ductwork and out into the rooms, so cleaning the ducts without the unit only goes so far. It’s worth booking a check, because nobody sees inside a duct day to day.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes anything from half a day for one small unit to several shifts for a plant room full of them. Pictures of the system and its access let us plan the work in Mayes Green before we set off.
- We start with a survey of the unit and a fixed quote for the work.
- With your site team, the unit is switched off and isolated, then the area around it protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- Standing water and slime come out of the tray and the drain is checked.
- You get a TR19® certificate and a photo report.
Before we arrive
- Move anything stored near the system
- Plan for cooking equipment or plant to be off before we arrive
- Agree a time when the area can be out of use
How to get a quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Other landmarks nearby include Abinger Castle (4.2 miles north) and Horsham Hospital (6 miles south-east). Not far away are Leith Hill and Vann Lake.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
