For landlords and property managers
Running several properties is easier with one contractor. We work across London and the South East, so a run of properties can go into one programme and kept on a regular cycle.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
Air conditioning servicing in South Ruislip, done properly
An air conditioning service is a check and clean of the whole system, indoor and outdoor units together. Filters and coils are cleaned, the drain is cleared, and the electrics, controls and refrigerant performance are all checked. We carry out air conditioning servicing for homes and businesses in South Ruislip and the rest of Greater London, for most leading brands. Typical jobs include no service record for the last year or more and weaker cooling than last year, across air-to-air heat pumps, wall-mounted split systems and VRF systems.
In South Ruislip, the outdoor unit can be on a balcony, a roof or a rear wall, as that affects how long the service takes. Managed buildings may need the visit booked through the agent.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before anything chargeable is done.

Your questions about air conditioning servicing in South Ruislip
Do you cover South Ruislip for air conditioning servicing?
Yes. We work across London and the South East from our base in East Grinstead, and South Ruislip is part of that. Tell us a little about the job and we’ll take it from there.
How do I get a quote for air conditioning servicing in South Ruislip?
Start with a short message: the address, what you need and a picture or two. Where pictures aren’t enough, a survey comes first and the fixed-price quote follows.
Do you have a 24/7 line?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will agree what happens next.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
How often should air conditioning be serviced?
Most systems are best serviced yearly. Some also need F-gas leak checks every 12 or 6 months, depending on their size and refrigerant, and we will tell you if yours does.
When is an F-gas leak check required?
The requirement starts at 5 tCO2e. Many small split systems fall below it: 3 kg of R32, for instance, is about 2.0 tCO2e. We read the charge from the label and work it out for you.
Do you work on systems someone else installed?
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.
What a service looks like in South Ruislip
VOA council tax data date about 42% of homes in the South Ruislip area to the post-war years, 1945 to 1972. Tell us where your outdoor unit is and how to reach it, so we can plan the visit. London outdoor units collect city dust and grime, so the outdoor coil gets particular attention on a service.

Common problems we fix in South Ruislip
How often a system needs servicing depends partly on how hard it works. A system used for heating as well as cooling, or one in a busy workplace, sees far more running hours and so builds up dirt more quickly.
These are the situations we see most often:
- No service record for the last year or more
- Weaker cooling than last year
- Systems that need a 6 or 12-monthly leak check
Schools such as Deanesfield Primary School can book servicing for half term or the summer break, when rooms are empty.

The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Parking bays, permits and roof or balcony access are the first things we ask about in South Ruislip.
- We ask about the system: the make, the number of indoor units and any problems you’ve noticed.
- The engineer switches the system on and checks how it behaves before taking anything apart.
- We clean the filters and coils and make sure the condensate drains away.
- Temperatures and pressures tell us how the refrigerant circuit is doing, alongside checks on the wiring and controls.
- A service record follows, with any faults and the options for fixing them.
How to prepare
- Make sure someone can let us in at the agreed time
- Clear a path to the units and the space around them
- Mention any managing agent or landlord rules we need to follow
