Extract fan repair for kitchens and businesses in Liss
If an extract fan in Liss is struggling or has stopped, we diagnose the fault and send you a fixed quote to repair or replace it. When the fan gives up mid-service, our 24/7 emergency line is there. We’re often asked to deal with a humming noise from the fan motor and a worn or slipping fan belt, on roof and wall fans, bearings and fan motors.
In a smaller place like Liss, a failed extract fan means a closed kitchen, and a closed kitchen loses trade. Our 24/7 emergency line is there for exactly that.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

When it’s something else
To be straight with you, there are a few things this work will not fix:
- Ductwork designed too small for the kitchen’s cooking
- Problems with the gas supply or its interlock valve
- Odour complaints that need filtration rather than a fan repair
If in doubt, ring 0345 646 2711, or email photos and we will say what we think.

Liss: your questions answered
Who would carry out a food hygiene inspection at a kitchen in Liss?
Kitchens in Liss are inspected by East Hampshire council’s environmental health officers. An officer may ask how the kitchen is ventilated, so keep repair records with your maintenance file.
Can the work in Liss be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Liss doesn’t have to lose a day’s trading. Just ring 0345 646 2711, or send details by email with your opening times and we’ll plan around them.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it does not spread.
What makes a kitchen extract fan rattle or whine?
It can be one of a few things, including bearings, belts, grease and mounts. It’s worth having it diagnosed before it leads to a breakdown.
Do you cover Liss?
Yes. Our area takes in London and the counties of South East England, and that includes Liss.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we’re on site, so we book a time when it would be closed anyway.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
Extract fans in Liss
Food Standards Agency data counts about 4 restaurants, cafés and works canteens within 1.5 miles or so of the middle of Liss. A kitchen with a dead extract fan gets hot and smoky fast, and kitchens like these feel it at once. Liss is about 47 miles from central London, well within the area we cover across London and the South East. The visit is fixed around your opening hours, not ours. In Liss, food businesses are inspected by environmental health officers from East Hampshire council. Under food hygiene rules, a kitchen needs suitable and sufficient ventilation. So a failed fan is worth fixing before the next service, not the next month.
If you run a kitchen close to Liss station and the extract fan is getting noisy, a planned repair after closing beats a breakdown at the rush. A fan that rarely runs, like one in a hall kitchen near Church of St Mary or elsewhere in Liss, can seize between uses. Holidays are the time to replace a tired kitchen fan at schools such as Liss Infant School, rather than mid-term.
Liss is about 3 miles north-east of Petersfield, in Hampshire. Liss gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where needed and a written report with photos. Our Hampshire coverage runs to 683 places, Liss among them. There’s also a page for Portsmouth, about 18 miles away.

Near you in Liss
Locally, jobs take us to businesses close to Whistle Stop pub. There’s a railway station in Liss itself: Liss station. Well-known places in the area include Petersfield Community Hospital (3.6 miles south-west) and Bear Museum (3.5 miles south-west). For a walk, there’s Liss Riverside Railway Walk South and Wheatham Hill.
How the visit works
The visit has three parts: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. The middle part takes longest, and that takes a few hours for most repairs, longer for a full fan replacement. Evenings, weekends or a closed day all work for a site in a place like Liss.
- We take details of the symptoms and book a time that suits the kitchen.
- On site, the fan is safely isolated.
- The fan and its controls are checked to pin down the fault.
- A fixed quote for the repair or replacement follows.
- We fix the fault and run the fan to check it.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What happens if it’s left?
Vibration does damage beyond the fan. It loosens fixings, strains duct connections and wears the housing, so a small repair can grow into a bigger one. A site near Liss that has to close at short notice is hard to cover for.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Aftercare tips
So the system stays in good health:
- Make sure every filter is in place and clean
- Save our number for the 24/7 emergency line
- Note when the fan trips or cuts out
- Keep all filters fitted while cooking
If the fan had grease on it, the rest of the system almost certainly does too. We can book a TR19® clean of the whole extract, with a certificate and photo report.
Small faults, like a worn belt, are quick to fix. Left for months, they can damage the motor or bearings so early attention pays.
How we price extract fan repair
Your quote is based on your site. We consider:
- The condition of the system
- When the work can happen, such as evenings, overnight or weekends
- How big the system is
- Access, including roofs, risers and ceiling voids
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
What we need to know
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Your last certificate, test record or report
- A few general shots of the system
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
If you need extract fan repair in Liss, ring 0345 646 2711, or email photos. Let us know the site type and the opening hours, and send photos or your last report if you can. We typically send a fixed quote within one working day.
What the work involves, part by part
Motors and bearings
Rumbling and grinding typically come from the bearings. We diagnose whether it’s the bearings or the motor itself before recommending a fix.
Fan controls
Speed controllers and isolators sit between the supply and the fan. When they fail, the fan may not start or may run at the wrong speed.
Staff cleaning versus specialist work
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 and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
