- Air conditioning that is not cooling as well as it did
How we handle air conditioning servicing in Mortlake
A service is as much a check-up as a clean. We listen to the fans, look at the pipework and insulation, test the controls and check the electrical connections are sound, and tells you about anything that looks like it’s heading for trouble. The work covers wall-mounted split systems, VRF systems and ducted systems, and the jobs we see most are a musty or damp smell when the unit starts and iced-up coils or pipework.
Commercial systems in a London area like Mortlake may need F-gas leak checks as well as a service, depending on its refrigerant charge. We record the checks and tell you when the next one is due.
Nothing is signed off by word of mouth: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

What we do, step by step
Each visit follows the same order: check the plan with you, protect the area, carry out the job, test what we’ve done and explain it all to you. On site, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. For a job in Mortlake, tell us about parking, permits and access to the building when you get in touch.
- We start with the basics, such as the brand, the number of indoor units and any symptoms.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- Filters, coils and the condensate drain are cleaned and cleared.
- The wiring, controls and refrigerant performance are checked, plus a leak check on systems large enough to need one.
- We leave you a record of the service and explain anything we found.
How to prepare
- Clear access to the fuse board
- Clear a path to the units and the space around them
- Keep pets and children away from the work area

Your questions about air conditioning servicing in Mortlake
Can I get a fixed-price quote for air conditioning servicing in Mortlake?
The easiest way is to phone 07833 053749 or fill in the contact form with a few details and pictures. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Is Mortlake in your area for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and Mortlake is part of that. Get in touch with the details and we reply the same working day.
When is an F-gas leak check required?
The rules are based on tCO2e, which comes from the refrigerant charge and its GWP. 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 holding less than 10 tCO2e do not need them.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
Is a regas part of an air conditioning service?
Refrigerant is only added after the leak that caused the loss has been dealt with. Topping up without finding the leak means the gas escapes again and that is money wasted.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
Who is responsible for leak checks?
The F-gas rules share it between the equipment’s operator and the engineers who work on it. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.
When to call us in Mortlake
Small refrigerant leaks do not announce themselves. Performance drops slowly and only becomes obvious when the weather is at its extreme.
These are the situations we see most often:
- Systems that haven’t been serviced for a while
- Water dripping from the indoor unit
- F-gas leak checks falling due
For a school like Thomson House School, maintenance visits can be booked out of term.
Before you book anyone
- Which brand and model they’re proposing, and why
- Whether you get F-Gas records where refrigerant is involved
- If the figure could change on the day
What happens if it’s left?
Smells from an indoor unit tend to come back each time it runs. The cure is cleaning where the dirt has built up instead of covering it up. Planning ahead in Mortlake means you choose the date, not the weather.
The pipe route, the height of the units and how we reach them can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
Why us?
- We work on all the leading brands
- 24/7 emergency line for breakdowns
- A reply the same working day
- Covering London and the South East
