How we handle air conditioning repair in Colney Street
Our emergency line runs 24/7 for urgent breakdowns, from an overheating comms room to water leaking from a unit. Ring 07833 053749 with the make, what’s happening and any code, and we’ll agree the next steps. The work covers VRF systems, ceiling cassettes and heat pumps, and common reasons people get in touch are ice on the pipework or the coil and drips from the indoor unit.
Around Colney Street, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Keeping the system healthy
Looking after it is simple, and it helps at the next service:
- Ask for the leak to be found, not just a top-up
- Rule out the simple causes first: filter, mode and temperature
- Turn the system off if it’s dripping water
If the same symptom comes back, tell us right away. Describe what’s happening and any error code, and we’ll look into it.
Filter cleaning is the simplest prevention there is. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance and the manual shows how to clean them.
What a repair looks like in Colney Street
About 40% of homes across Colney Street and its surrounding area date from 1945 to 1972, according to the Valuation Office Agency’s council tax figures, and about 62% of households live in detached or semi-detached houses, according to the last census (2021). If the outdoor unit is high up or behind a locked gate, mention it when you book. The George and Dragon Public House, listed at grade II, is one of roughly 6 protected buildings and structures in the half-mile around Colney Street’s centre. We keep it in mind in case a new outdoor unit is ever needed, as protected buildings can need consent for that.
For a school like Park Street Church of England Voluntary Aided Primary School, urgent repairs can be booked straight away and bigger work in the holidays.

Do you cover smaller places like Colney Street?
Yes. Colney Street is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.
Who has to arrange F-Gas leak checks?
The operator of the equipment, working with qualified engineers. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
What does the error code on my air conditioning mean?
Codes differ by brand, and the same code can cover several faults. Tell us the code, the make and the model and we will test the system to confirm the cause.
How soon will you get back to me?
You’ll hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Do you work on commercial properties?
Yes. From one rented home to commercial buildings, the approach is the same: survey or diagnosis, a fixed price and proper paperwork.
Common problems we fix in Colney Street
When ice forms on the pipes or coil, something else is wrong. It usually points to poor airflow, such as a clogged filter or a fan problem, or to a refrigerant leak. Turn it off and let the ice melt, then call us.
The things we’re asked about most are:
- A system that won’t switch on
- A system that runs but doesn’t cool the room
- Water dripping from the indoor unit
A photo of the error code and the unit’s rating label helps us plan the repair.

What air conditioning repair can’t fix

- A diagnosis visit finds the cause with proper tests.
- You get the cause explained and a fixed price for the repair.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- The system is run and checked, and you get a written note of the repair.
