Air Conditioning Repair in Leatherhead
Our engineers work in Leatherhead on air conditioning repair. A look at the job first, a fixed-price quote and written records at the end.
- Water dripping from the indoor unit
- A unit that won’t start
- Ice forming on the indoor unit or pipes
Keeping the system healthy
How well a system lasts depends on use and care. Here’s what we suggest:
- Write down the fault code if there is one
- Only let an F-Gas qualified engineer work on the refrigerant
- Leave space around the outdoor unit
Once the fault is fixed, we test the system in operation. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind, and we tell you about anything we noticed.
Book an annual service. The engineer cleans what you cannot reach and picks up problems before they cause a breakdown and that’s usually simpler than a breakdown repair.
Air conditioning repair in Leatherhead, done properly
A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. Topping up without a repair only delays the next breakdown. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If the problem is an error code or flashing light on the unit and water leaking from the unit or through the ceiling, we can help.
For a repair in Leatherhead, a photo of the error code and the unit’s rating label is a great start. That tells us the make, model and refrigerant, so we can plan the visit properly.
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 any chargeable work goes ahead.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what air conditioning repair will not do:
- An R22 system that has lost its refrigerant
- A room that overheats because of the building, such as a lack of shading or ventilation (the system may need help, not a repair)
- A system that was undersized for the room in the first place (that needs a bigger system, not a repair)
If in doubt, call us on 07833 053749 or use the quote form and we’ll say what we think.

Why it’s worth doing now in Leatherhead

Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you’re not sure what’s needed, call 07833 053749, or email if that’s easier for straight advice and a fixed price.

How the visit works
Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes a single visit for many faults, while some repairs need a second visit once parts arrive, and we clear up before we go. The more we can see first, the quicker the visit to Leatherhead.
- You describe the fault, the make and any error code, ideally with a photo.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- We run the system, check it’s working properly and note anything else that needs attention.
Before we arrive
- Make sure we can reach the outdoor unit, or where it will go
- Let us know if the units are on a roof, a high wall or in a locked area
- Plan for pets to be kept clear during the visit
Getting a quote
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
