Your questions about air conditioning repair in Hersham
Is Hersham in your area for air conditioning repair?
We do: Hersham falls inside our working area. Get in touch with the details and we reply the same working day.
Do you cover smaller places like Hersham?
We do. Villages and hamlets get the same service as the bigger towns. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Do you offer an emergency repair service?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Call 07833 053749 and tell us the make, the symptoms and any error code, and we will agree the next steps with you.
When will I hear back?
We reply to enquiries the same working day. For a breakdown that cannot wait, call our 24/7 emergency line.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is recorded, with F-Gas records where refrigerant work is involved.
Can you repair an R22 air conditioning system?
Most of the time, we recommend replacement. New R22 cannot be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is typically the better investment.
Are you F-Gas certified?
AirCon Doctor is an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.
Air conditioning repair in Hersham, done properly
Faults on all the leading makes are part of our everyday work, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. It does not matter who installed it, so tell us the make and model if you know it. We’re often asked to deal with a suspected refrigerant leak and new noises from the system, on multi-split systems, VRF systems and ceiling cassettes.
For a repair near Hersham, we bring the common parts and tools for the make you have, and any part that needs ordering is priced before it’s fitted.
The records are your system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler and it’s worth keeping safe.

How it works
If the system has to be off for part of the visit, we tell you before we start, so you can plan around it. For businesses, we can typically work room by room or zone by zone. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Because we plan from pictures or a survey, a job in Hersham can typically be finished in one visit.
- We start with what the unit is doing, the make and any code.
- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- Once agreed, the repair goes ahead.
- It’s tested running, and the write-up is left with you.
How to prepare
- Clear a path to the units and the space around them
- Let us know where the consumer unit is
- Name a contact who can meet us at the agreed time

What a repair looks like in Hersham
The last census (2021) found about 60% 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. The Hersham Village Conservation Area lies close to the centre of Hersham, within about a third of a mile. On the National Heritage List, around 4 entries fall within 0.5 miles of the middle of Hersham; The Barley Mow Public House (grade II) is one. Swapping an outdoor unit on a listed building or in a conservation area may need consent, so we will flag it if a replacement is needed.
If a system fails at a school such as Bell Farm Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays. Near Walton-On-Thames station, as anywhere, a photo of the error code on the controller is the quickest way to start a repair.

What affects the cost of air conditioning repair
We quote each job individually. This is what makes a difference:
- What we find on the survey or diagnosis
- What kind of system it is
- Whether we need access equipment for high-level work
A single unit or a whole estate, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before we start, with VAT shown clearly.
What we need to know
Simple jobs can often be priced from pictures and some basics. Send what you can of the following:
- Where the property is and what kind of building it is
- The paperwork from the last service, if you have it
- A close-up of the unit’s label showing the model number
Every quote starts with a look at the job, from a site survey or, where the job is straightforward, from pictures and measurements. After that, we send a fixed price before any work starts.
Landlords, agents and facilities managers
If you look after several properties, we can quote and plan the work across all of them. Every address has its own paperwork, so each one has its own history.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
What a customer said
“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.”
