- Frost or ice on the refrigerant pipes
Before you call an engineer
Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.
Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and ring us on 07833 053749, or email if that’s easier.
How we handle air conditioning servicing in Cranford
A service is not the same as a regas. The refrigerant circuit is sealed, so a system that’s short of gas has a leak somewhere. Where the checks suggest gas has been lost, the right step is to find the leak, and we will set out how. We’re often asked to deal with water dripping from the indoor unit and a unit showing a fault code, across ceiling cassettes, multi-split systems and VRF systems.
In Cranford, the outdoor unit can be on a balcony, a roof or a rear wall, so let us know how to get to it. If the building has a managing agent, we can book in with them.
Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Your questions about air conditioning servicing in Cranford
Can you do air conditioning servicing in Cranford?
We do: Cranford falls inside our working area. To start, give us a ring on 07833 053749 or fill in the contact form with a few photos.
What’s the best way to get a price for air conditioning servicing in Cranford?
Start with a short message: the address, what you need and a picture or two. Simple jobs can be priced from photos; otherwise we arrange a site survey and then give you a fixed-price quote.
How often does air con need a service?
Most systems are best serviced yearly. Larger systems may need leak checks every 12 or 6 months under the F-gas rules, and we will tell you if yours does.
Will you regas my air conditioning on a service?
We check refrigerant performance on every service, but adding gas is separate work. If gas has been lost, the right step is a leak search and repair, then a regas, priced before work begins.
Will servicing keep my manufacturer’s warranty valid?
Warranty terms are set by the manufacturer, not by us. Check your brand’s conditions, which may mention servicing and file every service record.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for breakdowns that can’t wait. Ring 07833 053749 any time and explain the problem.
Who has to arrange F-Gas leak checks?
Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. 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.
The process
The work area is kept tidy throughout, with sheets down and mess cleared as we go. If we need to drill through a wall, we agree the spot with you first. The visit takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. A few photos of the room, the outside wall and the fuse board help us plan a job in Cranford.
- You tell us the brand, the number of indoor units and any symptoms.
- Each indoor unit has its covers lifted so the filters, coil and tray can be cleaned.
- Outside, the coil is cleaned, the fan checked and the area cleared.
- Readings are taken on the electrics and refrigerant circuit, and the controls are tried in each mode.
- Anything we find is explained, with a fixed price if it needs a repair.
Getting ready for the visit
- Dig out any previous service or F-Gas records
- Keep pets and children away from the work area
- Clear access to the fuse board

Different systems, different jobs
Maintenance contracts
We tailor the schedule to how hard the system works, rather than a one-size plan.
Indoor and outdoor coils
Bent or damaged fins restrict the airflow across a coil. We note any damage and tell you if it’s affecting performance.
Air conditioning servicing in Cranford: the local picture
About 48% of homes across Cranford and its surrounding area were built between the wars, according to VOA council tax data. Access to the outdoor unit is the one detail that most changes how a visit is planned. City dust and debris build up on London outdoor units, which is why servicing matters. The Cranford Village Conservation Area lies close to the centre of Cranford, within about a third of a mile. Draw a one-mile circle round the middle of Cranford and it takes in 2 conservation areas. For most visits that makes no difference. It only comes up when an outdoor unit has to be replaced on a protected building.
If you look after a school such as Cranford Primary School, servicing is easiest in the holidays. A service once a year suits most home systems, and some business systems need more.
