Fixed quotes for AHU cleaning in Fairlands
There’s no set price list, because no two systems are the same. The quote depends on:
- A single visit or a regular plan
- How many systems or sites are involved
- Parking and loading at the site
- The size of the system
A single site or a whole portfolio, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.
What we need to know
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any access panels or hatches you can see
- The times we could work without disrupting the site
- Any previous report or certificate
Photos are the quickest way to a quote: 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 we can price many jobs without a visit.
AHU cleaning for kitchens and businesses in Fairlands
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’re dealing with fan sections that haven’t been cleaned in years and dirty filters cutting the airflow, we can help, from internal panels, heating and cooling coils and dampers and louvres onwards.
Work in a small place like Fairlands starts with agreeing access and timings, and the ventilation is inspected, cleaned and recorded the same as anywhere.
Good records are part of the job. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

How the job changes from site to site
Heating and cooling coils
Heating and cooling coils have tightly packed fins that trap fine dust. They’re cleaned using methods that will not bend or flatten the fins.
Internal casing and panels
We open each section through its doors and close them securely when we’re done, and check every one is shut.
When to call us in Fairlands
Mechanical servicing keeps a unit running, but it does not always include cleaning the inside. That means a unit can tick every service box and still be carrying years of dirt.
Most sites get in touch when they notice one of these:
- Debris and leaves in the fresh air intake
- Dust built up on fan impellers
- Filters that are clogged or overdue
- Blocked condensate drains and slimy trays
Wherever a school like Worplesdon Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

What else we do in Fairlands
Fairlands questions
Do you work in villages like Fairlands?
Yes. Villages and rural sites across the South East are part of our work, Fairlands included. The journey is planned ahead, so a few details about the route help.
Can the work in Fairlands be done at night or at weekends?
Yes, we can come after you close and finish before you open. That way a site in Fairlands doesn’t have to lose a day’s trading. Let us know the hours you’re closed and we will book within them.
Can you clean the ducts connected to the AHU?
Yes. We reach the ducts through access panels, and any sections we can’t reach are noted in the report, with new panels fitted where necessary.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before work begins, and waste is contained as we go. At the end, the area is cleaned down.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, from grease and debris to used cleaning water. None of it is left on site.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
Are you insured?
Yes, fully. CHAS and SafeContractor accreditation sit alongside it for clients who vet their contractors.
Aftercare tips
Once we’ve finished, these simple steps help:
- Report stiff or damaged access doors
- Watch for drips or damp patches near the plant
- Make sure condensate is draining away
- Keep filter changes on time and recorded
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.
Do not let leaves, litter or stored materials build up near the fresh air intake. Anything around the intake is likely to be drawn in.
The process
Your staff do not need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. We agree a date with you, plan the drive to Fairlands and turn up when the site is quiet.
- We agree a shutdown window that suits the building.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- The fan and drain tray are cleaned and the drain checked.
- After photos are taken and the certificate issued.
How to prepare
- Find the previous report, if there is one
- Mention any parking or loading restrictions
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

Advice
Why act early in Fairlands
Leave an AHU uncleaned and the dirt does not stay put. It’s carried through the ductwork and out of the grilles, which is why the unit and the ducts are best cleaned together. In a small place like Fairlands, a system that fails can take a site out of use.
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.
