About our air conditioning repair in Horsell
A symptom is only a clue: warm air, drips and error codes can each have several causes. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, so we diagnose before we repair. We are often asked to deal with rattling, buzzing or grinding noises and drips from the indoor unit, across ceiling cassettes, ducted systems and heat pumps.
Around Horsell, most of our repairs are in homes, with some small businesses. We plan the visit from what you tell us about the fault, so a description and a photo of any error code really help.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Refrigerant leaks
A low refrigerant charge always means a leak. We find it, repair it, pressure test the circuit, evacuate it and recharge to the manufacturer’s charge, and the work is recorded in the F-Gas records.
Circuit boards and sensors
Testing comes before any part is replaced, so you do not pay for a part that wasn’t the problem. Parts may need ordering, and we tell you if so.

When to call us in Horsell
Refrigerant leaks often start at joints: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Corrosion on coils can also cause leaks over time, and a slow leak can go unnoticed until the system stops cooling.
Look out for these signs:
- Water dripping from the indoor unit
- A flashing light and a system that won’t run
- A unit that barely blows any air
For a school like Woking High School, urgent repairs can be booked straight away and bigger work in the holidays.
What your quote should include
- Whether you get F-Gas records where refrigerant is involved
- Who does the electrical work, and whether they can certify it
- Whether testing, commissioning and paperwork are included
