Air conditioning servicing in Dudswell, done properly
People in Dudswell book a service for all sorts of reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that’s overdue. Whatever the reason, the visit follows the same thorough checks. If the problem is drips or damp patches below an indoor unit and noisy fans or rattling from the outdoor unit, we can sort it out.
Most systems around Dudswell need servicing once a year, ideally in spring before the warm weather.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

What a service looks like in Dudswell
The middle of Dudswell is part of the Dudswell Conservation Area. There are 2 conservation areas within a mile of the centre of Dudswell. Arne Cottage, listed at grade II, is one of roughly 6 protected buildings and structures in the half-mile around Dudswell’s centre. If a repair turns into a replacement on a listed building or in a conservation area, we check the planning position before changing the outdoor unit. About 72% of households live in detached or semi-detached houses, according to Census 2021 figures. Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day.
If you look after a school such as St Mary's CofE Primary School, servicing is easiest in the holidays. Spring is a good time for a service, before the system is needed for cooling.

Dudswell: your questions answered
Is Dudswell within the area you cover?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How often do you service systems in Dudswell?
A yearly visit is right for most households. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Whose job is it to check the system for leaks?
Responsibility is shared between the operator, normally whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.
Which accreditations do you hold?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
Is an F-gas leak check a legal requirement for my system?
The requirement starts at 5 tCO2e. Plenty of small splits sit under it, as 3 kg of R32 works out at about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
What does an air con service involve?
Filters, coils, fans and the condensate drain are all cleaned and checked. The electrics, controls and refrigerant circuit are tested too plus a leak check on systems that need one.
Will servicing keep my manufacturer’s warranty valid?
That’s down to your manufacturer’s terms, which vary. If servicing is required, a regular service record is the evidence, and we can explain what your brand asks for.

How we price air conditioning servicing
Typical ranges are on our prices page, and your quote is built on your job. The quote depends on:
- Whether we need access equipment for high-level work
- How many units are involved
- What state the existing equipment is in
What you pay reflects the actual work. That’s why every job is looked at first, and why the quote is fixed before work begins.
What to send for a quote
Good pictures often save a visit. The most useful are:
- Your installation or service records
- The remote or wall controller showing any error
- The outdoor side of the property, including any roof or flat area
Our prices page gives typical ranges, but your quote is based on your job, because every property is different. Once we’ve looked at the job, from pictures or on a survey, you get a fixed price. To start, phone 07833 053749 or write to us at info@aircondoctor.co.uk.
What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. For a village like Dudswell, tell us about narrow lanes, gates and parking when you book.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- If a repair is needed, you hear why and what it costs before anything is done.
Before we arrive
- Plan for pets to be kept clear during the visit
- Unlock any gate, garage or side passage we need
- Clear a path to the units and the space around them
Getting a quote
VAT is set out clearly on every quote, with the rate that applies to your job. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. To get one, call 07833 053749.
Related advice
Safe owner checks
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo or a short video of the display is even better.
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. If you need something moved, we can quote for it.
What air conditioning servicing cannot fix
Before you book, it helps to know what’s not included:
- Rooms that gain heat faster than any unit could cope with
- A system that’s too small for the room it serves
- Parts that have failed and need replacing
If in doubt, phone 07833 053749 or drop us a line and we’ll say what we think.
What the work covers
- Ceiling cassettes
- Air-to-air heat pumps
- Ducted systems
- Multi-split systems
- Wall-mounted split systems

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
