Air conditioning servicing in St Leonards, done properly
A manufacturer’s warranty can come with conditions, and regular servicing may be one of them. Each brand sets its own terms and we are happy to go through them with you. You get a record of each service to keep with the warranty paperwork. If you are dealing with no service record for the last year or more and ice forming on the pipework or outdoor unit, we can sort it out.
In a village like St Leonards, outdoor units often face hedges, fields or gardens, so leaves, seeds and cobwebs collect on the coil. A yearly service clears them.
Nothing is signed off by word of mouth: 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. File it with the manual so it’s to hand next time.

What affects the cost of air conditioning servicing
Typical ranges are on our prices page, but every job is priced on its own. What we look at:
- The distance and route between the indoor and outdoor units
- Access, including height, roofs and ladders
- The type of system, from a single split to a larger system
Leaving a fault or an overdue service rarely makes the work cheaper. Small problems, from blocked filters to slow leaks, tend to get worse, and a struggling system uses more electricity to do less. If you are unsure, phone us on 07833 053749 or fill in the contact form and we will give you an honest view and a fixed price.
Asking for a quote
To help us quote quickly, please include:
- Where the outdoor unit is, or where you’d like it
- The make and model of the system, from the label
- A few pictures of the room and the wall the unit is on, or will go on
The quickest way to a quote is to send pictures: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
When it’s something else
Some problems need a different service or another trade:
- Poor original installation, such as drains without a proper fall
- Rooms that gain heat faster than any unit could cope with
- A system that’s too small for the room it serves
If you are not sure, just call us on 07833 053749 or write to us at info@aircondoctor.co.uk and we’ll give you a straight answer before booking.

About 31 miles out from central London, St Leonards is part of the South East area we work across. Church of St Leonard, listed at grade II*, is one of roughly 3 protected buildings and structures in the half-mile around St Leonards’s centre. 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. Clean filters and coils help a system cool better and use less electricity.

What the work involves, system by system
Condensate drains and pumps
When the system cools, every indoor unit makes water. The tray is cleaned and the pipe flushed through so the water has a clear path out.
Maintenance contracts
With a contract, the number of visits, the scope and the cost are agreed in writing before the first visit. It suits homes and businesses alike.
The process
Our engineers arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes anything from an hour for a simple split system to most of a day for a larger installation. We plan the trip to St Leonards around you.
- You tell us the brand, the number of indoor units and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- We test the electrics, the controls and how the refrigerant circuit is performing.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Let us know if the building has a permit or sign-in process
- Let us know where we can park and unload
- Plan for pets to be kept clear during the visit
Getting a quote
Some jobs can be priced from photos, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, the quote is fixed before anything goes ahead.

Your questions about air conditioning servicing in St Leonards
How often should air conditioning in St Leonards be serviced?
For most homes, once a year. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Do you cover smaller places like St Leonards?
Yes, and the size of the place makes no difference to how we work. A few pictures and the postcode are enough to get things started.
When is an F-gas leak check required?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). From 5 to under 50 tCO2e, leak checks are required at least every 12 months, and from 50 to under 500 tCO2e every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
Do you protect the property while you work?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. At the end, we clear up and show you what we have done.
How quickly will you reply?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
How much time does an air con service need?
A service takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Any repair found on the day is priced and agreed before it’s done, and you can give us a ring on 07833 053749, or email if that’s easier to book.
Do you do service contracts for air con?
Yes, and the schedule is set around your system. The price is fixed with your quote and you get a record after each visit.
What a customer said
“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.”
