What's Involved in an Air Conditioning Service?
Regular servicing keeps a system running efficiently, protects the warranty and catches small problems before they become breakdowns. But what counts as 'a service' varies a lot between providers, so it's worth knowing what should actually be done.
Price is mainly driven by the number of indoor units, the type of system (wall-mounted splits are quicker than ducted or cassette systems), and access — a unit on a high wall or in a tight loft space takes longer to reach safely.
What a proper service includes
- Cleaning or replacing filters
- Cleaning the indoor coil and checking condensate drainage
- Checking refrigerant pressures and looking for signs of leaks
- Cleaning the outdoor coil and checking fan operation
- Checking electrical connections and controls
- Confirming the unit is running at its rated performance
What affects the price
- Number of indoor and outdoor units on site
- System type — wall splits, cassettes, ducted or floor consoles
- Access, including height, ladders or restricted plant rooms
- Whether it's a routine service or a service that uncovers a fault needing parts
How often to service
For most domestic systems, an annual service is enough to keep things running well. Commercial systems, particularly those running long hours in catering or retail environments, often benefit from twice-yearly visits, and F-Gas rules may require more frequent leak checks depending on the refrigerant charge size.
How we quote servicing
We can quote a one-off service or set up a maintenance contract with a fixed annual visit schedule. Either way you get a written quote before work begins, and any additional work found during the visit — such as a part needing replacement — is always agreed with you before we proceed.
FAQs
Common questions
How long does a service take?
A single wall-mounted split usually takes under an hour; multi-unit or commercial systems take longer depending on count and access.
Do I need to be present during a service?
For domestic visits it helps if someone can let us in, but for commercial sites we can often work directly with facilities contacts.
What happens if a fault is found during a service?
We'll explain what we've found and quote any necessary parts or repair work before proceeding, rather than adding surprise charges.
Does servicing affect my warranty?
Many manufacturers require evidence of regular servicing to keep a warranty valid, so keeping records matters.

How often should air conditioning be serviced?
Once or twice a year covers most systems, but comms rooms, kitchens and dusty industrial sites need more.
