Air conditioning servicing in Coldharbour
Servicing does not mean topping up refrigerant. The refrigerant circuit is sealed, so a system that is short of gas has a leak somewhere. If the performance checks point to a leak, we explain the options for finding and fixing it rather than just topping up. The work covers ducted systems, ceiling cassettes and multi-split systems, and people most often call us about F-gas leak checks falling due and frost or ice on the refrigerant pipes.
For a flat or office in Coldharbour, tell us where the outdoor unit is and how we reach it, so let us know how to get to it. If the building has a managing agent, we can book in with them.
The records are your system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

What we do, step by step
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 the rest is down to us. Before we leave, the area is tidied and we explain what we have done. Let us know who controls access to the building in Coldharbour, as that saves time on the day.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- The system is run and checked before anything is opened up.
- Filters, coils and the condensate drain are cleaned and cleared.
- Electrical connections, controls and refrigerant performance are checked, with an F-gas leak check where the system requires one.
- You get a service record, with anything that needs attention explained.
Before we arrive
- Mention any parking restrictions near the property
- Let us know if the units are on a roof, a high wall or in a locked area
- Move furniture away from the wall where we will be working

Air conditioning servicing in Coldharbour: the local picture
The middle of Coldharbour is part of the Coldharbour Conservation Area. Draw a one-mile circle round the middle of Coldharbour and it takes in 10 conservation areas. Church of St Matthias, listed at grade II*, is one of roughly 20 protected buildings and structures in the half-mile around Coldharbour’s centre. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be. About 82% of homes in and around Coldharbour have been built since 2000, according to Valuation Office Agency council tax records, and about 95% of households live in flats, according to the last census (2021). In flats, outdoor units are often on balconies, roofs or high walls, so tell us how we reach yours. In London, a yearly clean of the outdoor coil makes a real difference to how well a system cools.
Businesses close to Canary Wharf station can book an early or late slot so the service does not get in the way of trade. Schools such as Woolmore Primary School can book servicing for half term or the summer break, when rooms are empty.

How the job changes from property to property
Refrigerant performance and leak checks
To find tCO2e, multiply the kg of refrigerant by its GWP and divide by 1,000. As an example, 3 kg of R32 comes to about 2.0 tCO2e, while 3 kg of R410A is about 6.3 tCO2e. We check the label on your system and tell you where it sits.
Fans and electrics
Both units rely on fans to move air. The engineer listens for noise and checks for wobble or wear and cleans dust from the indoor fan.

Looking after your system
Here’s the after-treatment advice, in brief:
- Shut doors to the room so the system isn’t cooling the whole house
- Rinse the indoor unit filters every few weeks when the system is in heavy use
- Diary the next service before this one is forgotten
If you’d rather not keep track of service dates yourself, ask about a maintenance contract. The visits and the price are fixed with your quote so you don’t have to remember.
Act on the early signs. Odd noises, smells and drips are cheaper to sort out before they grow than once the system has stopped.
FAQs for Coldharbour
Does my air con in Coldharbour need a yearly service?
Usually once a year for homes, more often for busy business systems. Larger systems holding 5 tonnes CO2 equivalent or more also need a leak check at least every 12 months under the F-gas rules.
Can I get a fixed-price quote for air conditioning servicing in Coldharbour?
Send us pictures of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.
Will you regas my air conditioning on a service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas with a fixed price for each step.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.

Yes. We work in Coldharbour and the rest of Greater London, within the London and South East area we cover. For a fixed-price quote, give us a ring on 07833 053749.
Do you work on commercial properties?
Yes. From a single let flat to offices, shops and public buildings, we work the same way: survey or diagnosis, a fixed price and proper paperwork.
