Air conditioning servicing in Croydon
Is your Croydon air conditioning due a service? We maintain systems in flats, houses, shops and offices across the borough, whoever installed them. A yearly visit keeps the air clean, the running costs down and the drain clear, covers any leak check the law requires, and catches the small faults before the first hot weekend.

Name, number and postcode. We ring you to go through it.
- Systems fitted by anyone
- Leak checks where the law requires
- Written record every visit
What does a service include?
- Filters washed, the indoor coil and fan cleaned.
- Condensate drain flushed and tested, since a blocked drain is the usual cause of a dripping unit.
- Outdoor coil cleared of leaves, fluff and pollen.
- Electrical connections, isolator and controls checked.
- Supply and return air temperatures measured and recorded.
- Pipework and joints inspected, with a leak check where the refrigerant charge requires one.
How often should it be done?
Once a year for most homes, ideally in spring before the first heatwave. Cafés, salons and busy shops clog filters faster and may need two visits. If you have the manufacturer's handbook, follow its interval, because a warranty can hinge on it. In between, the washable filters in the indoor unit lift out and rinse under the tap.
When is a leak check required by law?
When the refrigerant charge reaches 5 tonnes of CO2 equivalent, counted by global warming potential rather than weight.
| Charge in the system | Check at least |
|---|---|
| From 5 tonnes, below 50 | Once every 12 months |
| From 50 tonnes, below 500 | Once every 6 months |
GOV.UK gives 5 tonnes as 2.4kg of R410A, which catches many larger domestic splits and most commercial systems, while a small unit on a lower-impact gas may sit below the line. A fitted leak detection system doubles the interval. The rating plate on your outdoor unit tells us where yours stands. Source: GOV.UK guidance.
What does a service cost?
Checkatrade's national guide is £70 to £120 per unit for a one-off service. Several units at one address, difficult access or a commercial system will move that, so tell us how many units you have and where they are and we will price the visit before we come. Source: Checkatrade cost guide.
Who is allowed to touch the refrigerant?
An engineer holding an F-gas qualification: Category 1 for anything, Category 2 for smaller systems, and Category 4 for leak checks that do not open the circuit. If the system belongs to someone else, the firm doing the work also needs a company certificate from an approved body. Cleaning a filter needs no qualification at all. Our F-gas guide explains how to check a firm. Sources: GOV.UK on qualifications; GOV.UK on companies.
Questions people ask
Will you service a unit another company installed?
Yes. The make and model from the label and any previous service sheet help, but neither is essential.
Does the service include topping up the gas?
No, because a sealed system should not lose any. If the charge is low there is a leak, and that is a repair, not a service.
I manage several flats with units. Can you do them in one go?
Yes. Send the addresses and we will group the visits.
