When air con fails in Westhumble
About 20 miles out from central London, Westhumble is part of the South East area we work across. Lovedon Cottage, listed at grade II, is one of roughly 10 protected buildings and structures in the half-mile around Westhumble’s centre. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
Shops and offices around Box Hill & Westhumble station often can’t wait for cooling to come back, which is what the 24/7 line is for. For a school like The Ashcombe School, urgent repairs can be booked straight away and bigger work in the holidays.

Your questions about air conditioning repair in Westhumble
Is there an emergency air con repair line for Westhumble?
Westhumble is within our area, and the emergency line is open 24/7. Have the make, model and error code ready, and we will talk you through what happens next.
Will you come out to Westhumble?
Yes. Westhumble is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
How long does the work take?
Your quote will say how long we expect to be there. In most cases, it takes as long as the fault needs, from a quick fix to a return visit for parts.
What can I do with an old R22 system?
In most cases, we recommend replacement. R22 cannot be topped up with new gas, and parts for old models are scarce, so a new system on a modern refrigerant is usually the better investment.
Can I do the refrigerant work myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Who is responsible for leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
What air conditioning repair can’t fix
In fairness, there are a few things this work will not fix:
- A building problem rather than a system fault
- A discontinued model with no parts available
- A unit that was never big enough for the room
If you’re not sure, just give us a ring on 07833 053749 or email us and we will give you a straight answer before you book.
Parts of the system we cover

System by system
Condensate drains and pumps
The condensate drain is behind most indoor unit leaks. Blockages, kinks and failed pumps are the usual causes, and a unit that has dropped out of level can leak.
Multi-split systems
On a multi-split, one outdoor unit serves several indoor units, so a fault outside can affect every room, while a fault inside may affect only one. That shapes the diagnosis and the repair.

Managing agents and facilities teams in Westhumble
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.
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.
How the visit works
The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Somewhere like Westhumble, it helps to know about lanes, gates and where to park.
- It starts with the symptoms: what the unit is doing, the make and any code on the display.
- The engineer reads the fault codes and checks the electrics, airflow, drain and refrigerant circuit.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- Finally the system is tested in operation and you get a note of the fault and the fix.
Getting ready for the visit
- Keep pets out of the rooms we are working in
- Clear a path to the units and the space around them
- Let us know where we can park and unload
