How we handle air conditioning servicing in Coulsdon
Servicing is also a chance to spot faults early. We listen to the fans, look at the pipework and insulation, test the controls and check the electrical connections are sound, then explains anything that looks like it could cause a problem later. If you are dealing with a system that struggles to cool on warm days and humming, rattling or squealing from the system, we can help.
In Coulsdon, the outdoor unit can be on a balcony, a roof or a rear wall, as that affects how long the service takes. Managed buildings may need the visit booked through the agent.
If a fault appears while the equipment is under the manufacturer’s warranty, tell us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

How the visit works
There’s very little for you to do on the day. Just let us in and point us to the units, or to where they’ll be fitted, and the rest is down to us. At the end, we tidy up and run through the work with you. Before a visit in Coulsdon, we ask where the van can stop and how we reach the outdoor unit.
- It begins with a few questions about the make, the rooms served and any symptoms.
- Inside, the filters, coil and drain tray of each indoor unit are cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- Electrical connections, controls and refrigerant performance are tested.
- If a repair is needed, you hear why and what it costs before anything is done.
How to prepare
- Have the make and model of any existing unit to hand
- Plan for pets to be kept clear during the visit
- Let us know if the units are on a roof, a high wall or in a locked area
Getting a price
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Tell us the address and what you need, and simple jobs can often be priced without a visit.

Common questions in Coulsdon
How often should air conditioning in Coulsdon be serviced?
Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Do you cover Coulsdon for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Coulsdon is part of that. To start, give us a ring on 07833 053749, or email if that’s easier with a few photos.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it, and the quote is based on that.
Does my air conditioning need an F-gas leak check?
Only if the system is at or above the threshold of 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for example, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Will you make a mess?
Floors and furniture near the work are covered with dust sheets before we start, and we tidy up as we go. Before we leave, we clear up and run through the work with you.
What air conditioning won’t do
We’d rather tell you now than sell you work that will not help, so these are the things it won’t cover:
- A system that’s too small for the room it serves
- A failed compressor, fan motor or circuit board, which needs a repair
- Pipework or drainage that was badly installed in the first place
If in doubt, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk and we will say what we think before you book.

For landlords and property managers
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed-price quote.
When the building owner and the occupier are different, the lease or tenancy agreement normally sets out who maintains what. We’re happy to deal with either side and send the records to whoever needs them.
What we are called out for in Coulsdon
The outdoor unit lives outside. Leaves, grime and plant growth gather on the fins and around the unit, which makes it harder for the unit to shed or pick up heat.
Keep an eye out for these signs:
- Drips or damp patches below an indoor unit
- Humming, rattling or squealing from the system
- Air conditioning that isn’t cooling as well as it did
Businesses close to Coulsdon South station can book an early or late slot so the service doesn’t get in the way of trade.
