Let and managed properties
If you look after several properties, we can quote and plan the work across all of them. Each property gets its own records, so each one has its own history.
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
Air conditioning repair for homes and businesses in Lower Sheering
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, so we diagnose before we repair. The work covers wall-mounted split systems, VRF systems and multi-split systems, and the jobs we see most are frost on the pipework and water dripping from the indoor unit.
We plan the trip to Lower Sheering so the repair can be finished in one visit where possible, unless a part has to come from the manufacturer.
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, so keep it safe.

Lower Sheering: your questions answered
Do you cover Lower Sheering for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Lower Sheering is part of that. Tell us a little about the job and we will take it from there.
Will you come out to Lower Sheering?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
What causes water to leak from an air conditioning unit?
The condensate drain or pump is the usual cause: a blockage, a kink or a pump that has stopped. Turn the system off to stop the water and give us a call.
What does F-Gas certified mean?
Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before booking anyone, and we are happy to show ours.
What does an air con repair cost?
A diagnosis call-out is from £75 + VAT. When we’ve found the fault, the repair is priced before we do it. The cost depends on the fault, the parts and access to the units.
When will I hear back?
We reply to enquiries the same working day. If it’s an emergency, ring the 24/7 line instead.
Can you repair an R22 air conditioning system?
Replacement is normally the better answer. New R22 can’t be used to service systems, and parts for older units are getting harder to find, so a new system on a modern refrigerant is normally the better investment.
What happens if it’s left?
A struggling system costs more to run. A dirty coil, a blocked filter or a low refrigerant charge all make the system work harder for less cooling, and the extra strain can shorten the life of the compressor. Getting the date in early helps for a place like Lower Sheering.

How it works
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there.

- You tell us the symptoms, the make and any error code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- We explain the cause in plain English and give you a fixed price.
- Once you are happy, the repair is done and any refrigerant work recorded.
- We test the system in operation and leave you a note of the fault and the fix.
Preparing for the visit
- Clear a path to the units and the space around them
- Find the manual or the paperwork for the system, if you have it
- Name a contact who can meet us at the agreed time

What else we do in Lower Sheering
Keeping the system healthy
Aftercare is straightforward, and it helps at the next service:
- Clear debris away from the outdoor fan
- If the breaker trips twice, leave it off
- Check the settings and the remote’s batteries first
Where a repair needs parts, we explain what’s been ordered and agree the return visit with you. Parts lead times depend on the supplier, so we keep you posted.
Sensible use helps. Moderate settings and a closed room mean less strain, so it is not running flat out all day.
