About our air conditioning servicing in Preston
Servicing does not mean topping up refrigerant. Refrigerant runs in a sealed circuit and shouldn’t need adding to. Where the checks suggest gas has been lost, the right step is to find the leak, and we will set out how. The work covers wall-mounted split systems, multi-split systems and VRF systems, and people most often call us about systems that need a 6 or 12-monthly leak check and warning lights on the indoor unit.
Several units at a home near Preston can be serviced in one visit, which keeps it simple.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

How we price air conditioning servicing
Typical ranges are on our prices page, but every job is priced on its own. What we look at:
- Which make and model is being fitted or worked on
- A single visit or a regular plan
- The pipe route between the units
Every job is different, so we price each one individually. The system, the access, the pipe routes and the parts involved all make a difference.
Asking for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- A short video of any fault, such as a noise or a flashing light
- Any previous service or F-Gas records
- The fuse board and where it is in the property
Want a quote for air conditioning servicing? Please call 07833 053749 or fill in the contact form with a few details about the property. We will talk you through the options and give you a fixed-price quote before anything is booked.
How it works
If the system has to be off for part of the visit, we tell you before work begins so it doesn’t catch you out. For businesses, we can normally work room by room or zone by zone. 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 of the property help us plan a visit to Preston.
- We book a time that suits you and confirm the price.
- We switch the system on and check it in operation.
- We clean the filters, coils and fans and clear the condensate drain.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- A final test run follows, then you get the service record.
How to prepare
- Let us know where we can park and unload
- Plan for pets to be kept clear during the visit
- Make sure someone can let us in at the agreed time
Ask for a quote
Here’s what helps us quote: the address and the type of property, a few photos, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then give us a ring on 07833 053749, or email if that’s easier.

What a service looks like in Preston
About 37% of homes in and around Preston were built before 1919, according to Valuation Office Agency council tax records, and Census 2021 figures found about 78% of households in detached or semi-detached houses. Let us know where the outdoor unit sits and whether a ladder is needed to reach it. Central Preston is inside a conservation area. Historic England lists about 25 buildings and structures within half a mile of the centre of Preston, including Church of St Mildred (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Most homes book one service a year; busy offices and shops may want more. Schools such as Preston Primary School can book servicing for half term or the summer break, when rooms are empty.
Preston is about 6 miles south-east of Herne Bay, in Kent. Preston gets the same approach as every job we take on: diagnosis first, a fixed price and proper paperwork when we’ve finished. Across Kent, we cover 922 places, and Preston is one of them. For properties nearby, see our Bromley page, about 53 miles away.
Our engineers work on The Street, The Forstal and Park Lane and the roads around them. If your postcode is in CT3, you’re inside the area we cover. Close by, we work in Grove (1 mile north-west), West Stourmouth (1 mile north), East Stourmouth (1 mile north-east), Upstreet (2 miles north-west) and Ware (2 miles east). We also work in nearby towns such as Canterbury (6 miles west), Margate (9 miles north-east), Dover (12 miles south) and Folkestone (15 miles south).
What’s near Preston

Looking after your system
Aftercare is straightforward, and it makes the next visit easier:
- Hold on to every service report
- Book the service at least once a year
- Make sure the condensate outlet can drain
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. We agree the visits and the cost up front so you do not have to remember.
Don’t ignore small changes. Odd noises, smells and drips are cheaper to sort out before they grow than once the system has stopped.
Honest limits
Before booking, it helps to know what’s not included:
- Cooling capacity that does not match the space
- Rooms that gain heat faster than any unit could cope with
- Lost refrigerant, where the fix is a leak repair
Not sure which it is? You can ring 07833 053749 or drop us a line and we’ll tell you honestly.

Common questions in Preston
Does my air con in Preston need a yearly service?
For most homes, once a year. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you cover smaller places like Preston?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Every visit is recorded and F-Gas records kept where they apply.
When will I hear back?
You’ll hear from us the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Do you provide F-Gas records?
Yes. Every visit is written up, and any work on the refrigerant circuit goes in the F-Gas records. File them with the system’s paperwork.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Does my air conditioning need an F-gas leak check?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. 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 holding less than 10 tCO2e do not need them.
