Air conditioning repair in Coldharbour
Refrigerant does not get used up, so a low charge means a leak somewhere. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. If the problem is a fault code on the display and frost on the pipework, we can help.
In a London area like Coldharbour, a lot of the systems we repair serve flats and small offices, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
We’re an F-Gas certified company, NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Why deal with it now?
Small faults rarely stay small. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should and early diagnosis typically keeps the repair simpler. If a lease or managing agent is involved in Coldharbour, start the conversation early.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so you know where you stand.

What air conditioning won’t do
Some problems need a different service or another trade:
- A building problem rather than a system fault
- A power cut or a fault on the incoming supply to the building (that is for the network operator)
- Cooling that falls short because the system is too small

FAQs for Coldharbour
Can I get a fixed-price quote for air conditioning repair in Coldharbour?
The easiest way is to phone 07833 053749 with a few details and pictures. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
Is Coldharbour in your area for air conditioning repair?
Yes. Coldharbour is one of the places we cover. Tell us a little about the job and we’ll take it from there.
What accreditations do you have?
As the law requires for refrigerant work, we are an F-Gas certified company. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Do I need to service the system to keep the warranty?
That depends on the brand. If servicing is in the terms, missing one could affect a claim, so we explain the terms on your quote.
Why is my air conditioning leaking water?
The condensate drain or pump is the usual cause: a blocked pipe, a kinked hose or a failed pump. Turn the system off to stop the water and give us a call.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
What causes ice on the indoor coil?
When airflow drops or refrigerant is lost, the coil gets cold enough to ice. Check the filter first, and if it’s clean, the system needs a diagnosis.
