About our air conditioning servicing in Cassington
We’re asked to service systems for many different reasons: smells at start-up, a unit that struggles on hot days, drips from the indoor unit, or a service that is overdue. Whatever the reason, the visit follows the same thorough checks. Typical jobs include iced-up coils or pipework and systems that need a 6 or 12-monthly leak check, on VRF systems, wall-mounted split systems and ceiling cassettes.
Several units at a home near Cassington can be serviced in one visit.
Equipment warranty comes from the manufacturer, on its own terms, and we explain those terms on your quote. Terms differ from brand to brand, and we are happy to talk you through them.

Why deal with it now?
For most systems at or over 5 tCO2e, leak checks are a legal requirement, not a choice. Skipping a year leaves a gap in the records the rules expect you to keep, and it’s simpler to keep to the schedule. A dirty or faulty system works harder and costs more to run.
The cost depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. We give you a fixed price before work begins, so you know where you stand.
Why book with us
- A fixed price before any work starts
- MCS certified heat pump installers
- Clear warranty information from the manufacturer
- NICEIC approved for electrical work

Honest limits
Before booking, it helps to know what’s not included:
- Pipework or drainage that was badly installed in the first place
- A system short of gas because of a leak
- A failed compressor, fan motor or circuit board, which needs a repair

Different systems, different jobs
Fans and electrics
We look at the wiring and terminals for anything loose or discoloured. Loose connections can cause faults that come and go, so this matters.
Maintenance contracts
The visit frequency is set around the system and how it’s used so it fits your site.
How it works
Refrigerant work is done by qualified engineers working for an F-Gas certified company, and electrical work is done by us as NICEIC approved contractors. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes an hour or so for a single wall-mounted unit, longer for a multi-split system. For a village like Cassington, tell us about narrow lanes, gates and parking when you book.
- When you book, we ask what make it is, how many rooms it serves and whether anything seems wrong.
- The system is run and checked before anything is opened up.
- Filters, coils and the condensate drain are cleaned and cleared.
- We check the electrics, the controls and how the refrigerant circuit is performing, and carry out a leak check where the rules call for it.
- We leave you a record of the service and explain anything we found.
Getting ready for the visit
- Clear the space around the indoor unit, or where it will go
- Tell us about parking and loading
- Clear access to the fuse board

FAQs for Cassington
Does my air con in Cassington need a yearly service?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
Will you come out to Cassington?
Yes. Cassington is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
When is an F-gas leak check required?
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 instance, is about 2.0 tCO2e. We check the label and tell you whether your system needs checks and how often.
How soon will you get back to me?
We reply to enquiries the same working day. For a breakdown that can’t wait, call our 24/7 emergency line.
Is a regas part of an air conditioning service?
The service checks how the refrigerant circuit is performing, but does not include adding gas. If it’s low, a leak repair comes first and the regas follows, priced before any work starts.
Will you work on another installer’s system?
Yes. We look at it first and tell you what we find, including any issues with how it was fitted. Any work is priced before it goes ahead.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and we hold it.
What a service looks like in Cassington
VOA council tax data date about 40% of homes in the Cassington area to the post-war years, 1945 to 1972, and about 71% of households live in detached or semi-detached houses, according to Census 2021 figures. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. The middle of Cassington is part of the Cassington Conservation Area. Listed buildings are part of the picture here: about 22 within half a mile of the centre, such as Church of St Peter (grade I). For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
For a school like St Peter's Church of England Primary School, maintenance visits can be booked out of term. A service once a year suits most home systems, and some business systems need more.
