How we handle air conditioning repair in Twineham
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. A unit blowing warm air might have a blocked filter, a failed sensor, a fault on the circuit board or a refrigerant leak, so we diagnose before we repair. The work covers wall-mounted split systems, multi-split systems and ducted systems, and the jobs we see most are a unit blowing warm air and a unit that barely blows any air.
Around Twineham, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Twineham: your questions answered
Who do I call if my air conditioning fails in Twineham out of hours?
Yes. Our 24/7 emergency line covers Twineham. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Can you do air conditioning repair in Twineham?
Yes. Twineham is one of the places we cover. Just phone 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.
How quickly will you reply?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, with a fixed price before work starts.
Do you work for landlords and businesses?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Tell us who should receive the paperwork.
Why is my air conditioning icing up?
The coil gets too cold when air can’t move across it or when the refrigerant charge is low. Check the filter first, and if it’s clean, the system needs a diagnosis.
Is it legal to repair an R410A system?
Yes. Repairing and recharging existing R410A systems is still legal. As the GB phase-down continues, R410A is getting harder and dearer to buy and we talk through repair against replacement for older systems.
My system uses R22. Can it be repaired?
Most of the time, we recommend replacement. R22 can’t be topped up with new gas, and parts for old models are scarce, so we will quote for a modern replacement and explain why.
For landlords and property managers
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is and we are happy to deal with whoever it is.
Larger air conditioning systems in buildings need more than servicing: 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.
What happens on the day
There’s very little for you to do on the day. Someone needs to let us in and show us the units, or where they’re going, and the rest is down to us. At the end, we tidy up and run through the work with you. Photos of the existing unit help with repairs and servicing in Twineham.
- Tell us the make, the symptoms and any error code, and send a photo of the display if you can.
- At the property, readings and tests narrow the problem down to its cause.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- The fix goes in, with any refrigerant work tested and written into the F-Gas records.
- We run the system, check it’s working properly and note anything else that needs attention.
How to prepare
- Have the make and model of any existing unit to hand
- Keep pets out of the rooms we are working in
- Mention any parking restrictions near the property

What you can do yourself, and what needs us
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
There are a few things you can safely do yourself: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Anything inside the units, the electrics and the refrigerant is engineer’s work.

What else we do in Twineham
Leave it or put it right?
Leaving a fault seldom makes it go away. A drip can turn into a damaged ceiling, and a slow leak can leave the compressor straining, so getting it looked at early typically means a simpler repair. A system that is left with a fault, or without a service, typically costs more to run.
Putting several jobs into one visit can make for a more efficient booking. Mention every unit or room you need covered, and you’ll get one fixed price.
