How the job changes from property to property
Condensate drains and pumps
The drain is cleared, the pump tested and the fall checked, so the water goes where it should. Failed pumps are replaced and test it before we leave.
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.
About our air conditioning repair in Seven Sisters
Not sure whether it’s worth calling an engineer? A quick check of the filter, settings and remote can rule out the simple causes, then call 07833 053749 or drop us a line if the problem is still there. We reply to enquiries the same working day. If the problem is an error code or flashing light on the unit and frost on the pipework, we can sort it out.
In a managed building in Seven Sisters, the repair may need booking through the agent or building manager, so tell us who controls access. Roof access can need keys or permits, and we plan for that before we arrive.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

Common questions in Seven Sisters
Who do I call if my air conditioning fails in Seven Sisters out of hours?
The emergency line is open around the clock, and Seven Sisters is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Is Seven Sisters in your area for air conditioning repair?
Yes. We work across London and the South East from our base in East Grinstead, and Seven Sisters is part of that. Tell us a little about the job and we’ll take it from there.
What can I do with an old R22 system?
Most of the time, we recommend replacement. R22 can’t be topped up with new gas, and parts for old models are scarce, so we’ll quote for a modern replacement and explain why.
How soon will you get back to me?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
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 the law, not just our preference, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Do you work on commercial properties?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Why is there ice on my air conditioning pipes?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first and if that is not it, we’ll find the cause.
Safe owner checks
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and give us a ring on 07833 053749 or use the quote form.

How it works
Protection comes first: sheets over the floor and any furniture nearby and nothing is moved without asking you. Then the electrics are made safe and the work begins. It takes a single visit for many faults, while some repairs need a second visit once parts arrive, and we clear up before we go. For a job in Seven Sisters, tell us about parking, permits and access to the building when you get in touch.
- First the diagnosis: fault codes read, electrics and airflow checked, drain and refrigerant tested.
- Prescribe: tell you the cause and the fixed cost of the cure.
- Where a repair does not make sense, you’ll hear it from us, with the alternatives.
- The treatment: the repair itself, with any leak found and fixed before recharging.
- Finally, a check that it’s working and a record of what we did.
Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Unlock any gate, garage or side passage we need
- Clear a path to the units and the space around them
How to get a quote
Some jobs can be priced from photos, while others need a survey. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, the quote is fixed before anything goes ahead.

What air conditioning repair cannot fix
We won’t sell you work that does not address the problem, so these are the things it will not cover:
- A refrigerant fault on an R22 system (new R22 cannot be used for servicing, so replacement is usually the answer)
- A unit whose parts are no longer made (replacement may be the only option)
- Heat gains the system was never designed for
If in doubt, call us on 07833 053749 or fill in the contact form and we’ll say what we think before booking.
