Servicing in Writtle: local notes
The Valuation Office Agency’s council tax figures date about 60% of homes in and around Writtle to the post-war years, 1945 to 1972, and the last census (2021) found about 73% of households in detached or semi-detached houses. Access to the outdoor unit is the one detail that most changes how a visit is planned. Roughly a third of a mile or less from central Writtle, you reach the Writtle Conservation Area. Historic England lists about 43 buildings and structures within half a mile of the centre of Writtle, including Church of All Saints (grade II*). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first.
Most homes book one service a year; busy offices and shops may want more.

How we handle air conditioning servicing in Writtle
For an annual service, the price is £95–£150 + VAT, confirmed before the visit is booked. Larger systems with several indoor units, ducted units or commercial plant are priced on their details. There’s no guessing at the bill afterwards. If you are dealing with noisy fans or rattling from the outdoor unit and ice forming on the pipework or outdoor unit, we can sort it out.
In a place like Writtle, the outdoor unit often sits near a garden, hedge or trees, so the outdoor coil can clog with leaves and seeds. Every service includes cleaning it.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Owner checks or an engineer?
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. Ask us to quote for a move instead.
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what air conditioning servicing will not do:
- Major component failures that call for a repair visit
- A system short of gas because of a leak
- Heat gains the system was never sized for
Not sure which it is? You can give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll tell you honestly before booking.
Parts of the system we cover
- Ceiling cassettes
- Air-to-air heat pumps
- VRF systems
- Wall-mounted split systems
- Multi-split systems
- Ducted systems
When to call us in Writtle
Systems that run most of the year collect dirt faster than ones used on a few hot days. A system used for heating as well as cooling, or one in a busy workplace, sees far more running hours, and they benefit from regular attention.
These are the situations we see most often:
- Systems that haven’t been serviced for a while
- Leak check records that need bringing up to date
- New noises from the indoor or outdoor unit
For a school like Writtle Infant School, maintenance visits can be booked out of term.

How it works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. On site, it takes an hour or two for most homes, and longer where there are several indoor units or a ducted system. Photos of the room and the outside wall help us plan a job near Writtle.
- First, we agree a time and confirm the cost of the service.
- The engineer runs the system and checks how it’s performing.
- We clean the filters, coils and fans and clear the condensate drain.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- It’s run once more to confirm all is well, and the record is left with you.
Getting ready for the visit
- Let us know where the consumer unit is
- Tell us about parking and loading
- Find the manual or the paperwork for the system, if you have it

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price so you know the cost before we begin.

Writtle questions
How often do you service systems in Writtle?
Once a year suits most home systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Will you come out to Writtle?
Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
When is an F-gas leak check required?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
Do you work on all makes?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Who has to arrange F-Gas leak checks?
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 every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
