How the job changes from property to property
Fans and electrics
The indoor and outdoor fans move the air across the coils. The engineer listens for noise and checks for wobble or wear and clean the indoor fan where dust has built up.
Refrigerant performance and leak checks
The engineer looks at how well the system is moving heat, using temperatures and pressures to see whether it’s working as it should. If the readings suggest gas has been lost, we explain what that means.
About our air conditioning servicing in Croxley Green
Many manufacturers attach conditions to their warranties, and some of those may include regular servicing. The terms differ from brand to brand, so it’s worth reading yours and we’re happy to go through them with you. Our service record shows the work was done. If you are dealing with a system that struggles to cool on warm days and a musty or damp smell when the unit starts, we can sort it out.
Most systems around Croxley Green need servicing once a year, best done before summer.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

Let and managed properties
Bigger systems bring extra duties: a TM44 inspection by an accredited energy assessor is required at least every 5 years for systems over 12 kW. We can arrange it, prepare the system for it and fix what it finds.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system, and we can work for either side.
Common questions in Croxley Green
Will you come out to Croxley Green?
Yes, and the size of the place makes no difference to how we work. Send a few details and pictures, and we reply the same working day.
Does my air con in Croxley Green need a yearly service?
A yearly visit is right for most households. Some manufacturers’ warranty terms ask for regular servicing, so it’s worth keeping the records.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
Can I fit air conditioning or a heat pump myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s a legal requirement, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.
Do you offer emergency call-outs?
Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
Which brands do you work with?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For a new system, we suggest the make and model that suit the property and tell you why.
How quickly will you reply?
The same working day. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.

What we do, step by step
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. We agree a date with you and plan the visit to Croxley Green so we arrive with what’s needed.
- A date is fixed and the service price confirmed in advance.
- Before any cleaning, the system is run so we can see how it behaves.
- Then the cleaning: filters, coils, fan and the drain line.
- The electrics, controls and refrigerant performance are checked, with a leak check where required.
- A final test run follows, then you get the service record.
How to prepare
- Make sure someone can let us in at the agreed time
- Let us know if the building has a permit or sign-in process
- Tell us about access, such as roof hatches, high walls or locked plant areas

What owners can safely do
There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Do not move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
