About our air conditioning servicing in Lexden
Some systems need F-gas leak checks by law, and some do not. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. If you are dealing with weaker cooling than last year and systems that haven’t been serviced for a while, we can help.
We book services in Lexden at a time that suits you, and most single systems take an hour or two.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

How it works
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we’ve done and explain it all to you. The visit itself takes a short visit for one split system, longer for multi-split, ducted or commercial plant. Around Lexden, access is usually simple, though gates and garden access are worth mentioning.
- First, we agree a time and confirm the cost of the service.
- We switch the system on and check it in operation.
- We clean the filters, coils and fans and clear the condensate drain.
- Electrical and refrigerant checks follow, including a leak check if the rules require one.
- A final test run follows, then you get the service record.
Preparing for the visit
- Make sure we can reach the consumer unit or fuse board
- Make sure someone can let us in at the agreed time
- Dig out any previous service or F-Gas records

Lexden questions
Can you do air conditioning servicing in Lexden?
Yes. Lexden is one of the places we cover. Get in touch with the details and we reply the same working day.
Will you come out to Lexden?
Yes. Lexden is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you survey before quoting?
Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.
How often should air conditioning be serviced?
Yearly servicing is the usual starting point, with more visits for systems that run a lot. Check your manufacturer’s warranty conditions too, as they may set out servicing requirements.
Does my air conditioning need an F-gas leak check?
It depends on the system’s tonnes of CO2 equivalent (tCO2e). At 5 to under 50 tCO2e, it’s at least every 12 months; at 50 to under 500 tCO2e, every 6 months. Hermetically sealed systems under 10 tCO2e are exempt.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.

Indoor and outdoor coils
Outside, the coil gives off or picks up heat. Leaves, dirt and debris clog the fins, so we clean it and clear the area around the unit.

“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
