Whitsbury questions
Do you work overnight in Whitsbury?
Yes, we can come after you close and finish before you open. That way a site in Whitsbury doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you get to a site in Whitsbury?
Yes, Whitsbury is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
What happens to the waste?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
Do you repair air handling units?
AHU cleaning is what we offer here, not mechanical repairs. Any faults we notice are recorded so your maintenance contractor can deal with it.
What’s included in an AHU clean?
The main parts are the filters, coils, drain tray, fan and inside of the casing. We confirm the scope after looking at the unit.
Do you offer maintenance contracts?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
Do you do ventilation duct cleaning too?
Yes, supply and extract ducts, grilles and diffusers. We’ll tell you after the survey whether the ducts need it.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
AHU cleaning in Whitsbury, done properly
Coils are where a lot of the dirt ends up. 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. The work covers heating and cooling coils, supply and extract fans and internal panels, and common reasons people get in touch are condensate trays that won’t empty and units needing a clean before a new tenant or handover.
For a building in or near Whitsbury, access is agreed in advance and the visit is planned around the journey, and the ventilation is inspected, cleaned and recorded the same as anywhere.
A written report with photos follows each visit, 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.

Whitsbury buildings and their air
Salisbury District Hospital is the nearest hospital, about 5.2 miles north of Whitsbury. Healthcare ventilation is a good example of why supply ducts need inspecting: the air goes straight to patients.
Wherever a school like Western Downland Church of England Aided Primary School has ducted ventilation, a half-term visit keeps the work out of lesson time.

Do you need AHU cleaning in Whitsbury?
Wherever there’s a cooling coil, there’s condensate. If the drain tray outlet blocks or the tray doesn’t fall properly, water stands in it, and slime and smells soon follow.
Keep an eye out for any of the following:
- Plant that needs cleaning after a refit
- Drain trays holding standing water
- Leaves and litter drawn into the unit
- Rooms that smell stuffy when the system runs
Salisbury District Hospital, about 5.2 miles north, is the nearest hospital to Whitsbury, and healthcare sites of every size need their supply air kept clean.
Questions to ask before booking
- Whether a survey comes first
- How they set the interval to the next visit
- Whether they’re fully insured
- Whether the quote shows VAT
What your team can do, and what needs us
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
How we price AHU cleaning
Your quote is based on your site. We consider:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- How big the system is
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
Asking for a quote
What to send for a quote:
- Problems your staff have spotted
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- The site address and the type of premises
Quotes are quick. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Why act early in Whitsbury
Cleaning a unit while it only has light dust is quick. Leave it for years and dirt bakes onto coils and casings, particularly where damp has made it stick. It’s worth booking a check, because nobody sees inside a duct day to day.
The cost depends on the size of the system, what state it’s in and access to every part of it. You get a fixed price before we start, so there are no surprises.
Why choose Duct Doctor in Whitsbury
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- Evenings, overnight and weekends, plus 24/7 emergency callout
- Fixed quotes, usually within one working day
- Full insurance on every job

Different parts, different methods
Drain trays
Condensate from the coil drips into a tray beneath it. Standing water and slime are removed and the outlet is checked.
Fans and fan sections
Dust on a fan impeller adds weight and wear. Cleaning keeps it running as intended.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep the area around the fresh air intake clear
- Change filters on schedule and log each change
- Make sure condensate is draining away
- Flag stale or damp smells in the supply air
When we’ve closed the unit up, it can be restarted with your site team. Check the drain tray is emptying over the first few days to confirm water is draining away.
Make sure access doors and panels on the unit open easily. Sections that are awkward to open are the ones that get skipped.
What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes one overnight shift for many single units, with bigger plant phased. Rural roads and tight entrances are worth telling us about before a visit to Whitsbury.
- We start with a survey of the unit and a fixed quote for the work.
- The unit is shut down with your site team and the area protected.
- Filters are dealt with as agreed, and the coils, fan and casing cleaned.
- We clean out the drain tray and make sure it drains.
- You get a TR19® certificate and a photo report.
Before we arrive
- Clear loose items from the work area
- Let us know about permits to work or site inductions
- Agree a time when the area can be out of use
Getting a quote
To get a fixed quote, phone us on 0345 646 2711, or email photos and tell us the type of site, your opening hours and roughly what the system looks like. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.
