Landlords, agents and facilities managers
Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.
For anyone managing more than one building, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
What else we do in New Cross
Your questions about air conditioning repair in New Cross
Do you cover New Cross for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in New Cross. Have the make, model and error code ready, and we will talk you through what happens next.
Can you do air conditioning repair in New Cross?
Yes. New Cross is one of the places we cover. Just give us a ring on 07833 053749 or drop us a line with a few details.
Does servicing affect my warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
What does an air con repair cost?
The first step is a diagnosis, from £75 + VAT, and then you get a fixed price for the repair. You decide before any repair work starts.
What does F-Gas certified mean?
The law says any company working on equipment containing F gas has to be certified, and each engineer needs the right qualifications too. It’s how you know the refrigerant is being handled legally and safely.
Why is water dripping from my indoor unit?
Most of the time, it’s the condensate system: a blockage, a kink or a pump that has stopped. Switch the unit off to avoid water damage, then call us.
Do you survey before quoting?
Yes. We always look before we price, on a survey, or from your pictures and details where the job is simple. Then you get a fixed-price quote.
Common problems we fix in New Cross
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Corrosion on coils can also cause leaks over time and many leaks are slow enough to go unnoticed for a while.
Any of these is worth a proper look:
- A system that runs but doesn’t cool the room
- A flashing light and a system that will not run
- A system that needs topping up again
Schools such as Myatt Garden Primary School can report a fault on the 24/7 line and have non-urgent work done out of term.

Outdoor units serving flats can be awkward to reach, so let us know where yours is. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours.

How the visit works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes a single visit for many faults, while some repairs need a second visit once parts arrive. Photos of the room and where the outdoor unit could go let us plan most of a visit to New Cross in advance.
- You tell us the symptoms, the make and any error code.
- The engineer diagnoses the fault on site, testing rather than guessing.
- You get the cause explained and a fixed price for the repair.
- Once agreed, the repair goes ahead.
- It’s tested running, and the write-up is left with you.
Preparing for the visit
- Have the make and model of any existing unit to hand
- Make sure we can reach the outdoor unit, or where it will go
- Keep pets out of the rooms we are working in

Looking after it afterwards
So the system stays in good health:
- Never add refrigerant yourself or let anyone top up without finding the leak
- Have the system serviced once a year
- Keep the outdoor unit clear of leaves and clutter
A returning symptom is worth reporting quickly. Describe what’s happening and any error code and we will come back to it.
Filter cleaning is the simplest prevention there is. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.
