AHU cleaning in Munstead Heath, done properly
Drain trays under cooling coils are meant to empty. When the drain blocks, water sits there and the tray turns slimy, right in the path of the air going into the building. Cleaning and clearing it is a key part of the job. If you’re dealing with dust-coated heating and cooling coils and leaves and litter drawn into the unit, we can put it right.
Work in a small place like Munstead Heath starts with agreeing access and timings.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

How we price AHU cleaning
Sites vary more than people expect. The main factors:
- How many systems or sites are involved
- Parking and loading at the site
- Site requirements such as sign-in and permits
- The condition we find in the survey
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before work begins.
Helping us quote
What to send for a quote:
- The site address and the type of premises
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
If you need AHU cleaning in Munstead Heath, ring 0345 646 2711 or use the quote form. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote typically follows within one working day.

In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Between visits
How long the results last depends on use and care. Here’s what we suggest:
- Make sure condensate is draining away
- Watch for drips or damp patches near the plant
- Flag stale or damp smells in the supply air
- Keep the area around the fresh air intake clear
Once the clean is done, we send a TR19® certificate and a report with before and after pictures. Keep both with the building’s maintenance records.
Regular inspection under TR19® Air shows when cleaning is due instead of leaving it to guesswork.
For landlords and multi-site operators
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
FAQs for Munstead Heath
Will you come out to Munstead Heath?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
Do you do school ventilation cleaning in Munstead Heath in the summer holidays?
Yes, holiday work suits schools best. Around Munstead Heath, the Food Standards Agency lists about 4 schools and colleges with registered kitchens within a mile and a half or so. Tell us your holiday dates and we will book the visit for when the site is empty.
Do you need to switch the unit off?
Yes. The fan must be stopped and the unit isolated, so we plan it for a time that suits the building.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
How much does AHU cleaning cost in Munstead Heath?
Size, condition, access and working hours all affect the cost. Call for a fixed quote, normally ready within one working day.
Do you clean the ductwork as well?
Yes, supply and extract ducts, grilles and diffusers. The survey shows whether the ducts need cleaning now.
Do you have insurance?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is there a survey before the work?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
How it works
Your trading hours come first. We book the visit for a time the area is closed, whether that is an evening, overnight or a weekend. 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. In a small place like Munstead Heath, the journey is planned ahead and the visit arranged around the site’s hours.
- First we agree when the unit can be switched off, including evenings or weekends.
- We take before pictures of each section of the unit.
- We work through the unit from the intake to the outlet.
- We finish with the fan section and the drain tray.
- We take after pictures and issue the certificate and report.
Getting ready for the visit
- Tell us where we can park and unload
- Make sure someone can let us in and lock up afterwards
- Allow time for equipment near the work to be turned off and cool down
How to get a quote
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before we start.

What the work involves, part by part
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Drain trays
Standing water in a tray sits right where the air passes. We clean it and report anything about the tray or drain that needs fixing.
What a clean won’t put right
We will always give you a straight diagnosis, so here’s what AHU cleaning won’t do:
- Problems with the unit’s controls or sensors
- Dirty ducts beyond the unit itself
- Leaking heating or cooling coils
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer before you book.
