Air conditioning repair in Thedden, done properly
Age alone doesn’t decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. We’re often asked to deal with poor airflow even with clean filters and rattling, buzzing or grinding noises, on VRF systems, ceiling cassettes and heat pumps.
Around Thedden, outdoor units often sit close to gardens and hedges, and a coil clogged with leaves or seeds is a common cause of weak cooling.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What happens on the day
If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. For businesses, we can usually work room by room or zone by zone. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. If a lane or gateway near Thedden is tight for a van, let us know and we’ll plan for it.
- You describe the fault, the make and any error code, ideally with a photo.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- We explain the cause and give you a fixed price for the repair before any work goes ahead.
- We repair the fault, and where refrigerant is involved, the leak is found and fixed before recharging.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Preparing for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Tell us about any building rules, permits or sign-in
- Make sure we can reach the outdoor unit, or where it will go

Related advice
Signs you need air conditioning repair in Thedden
Leaks tend to start where pipes are joined: flare connections, brazed joints and valves, or pipework damaged or rubbed through by vibration. Corrosion on coils can also cause leaks over time, and a slow leak can go unnoticed until the system stops cooling.
Any of these is worth a proper look:
- A suspected refrigerant leak
- Weak airflow from the indoor unit
- A flashing light and a system that won’t run
Before you call, note what the unit is doing and any code on the controller.

Thedden questions
Is Thedden in your area for air conditioning repair?
Yes. Thedden is one of the places we cover. Get in touch with the details and we reply the same working day.
Do you cover smaller places like Thedden?
Yes, and the size of the place makes no difference to how we work. Visits to smaller places are planned so the engineer arrives with what the job needs.
How long does the work take?
It depends on the job, but as a guide it takes anything from an hour or so to a full day, depending on the fault and the parts. We will give you a firmer idea when we quote.
Why is my air conditioning blowing warm air?
Common causes are a blocked filter, the wrong mode or set temperature, an outdoor unit that cannot breathe, a failed sensor or board, or low refrigerant from a leak. Check the filter and the settings first, then phone 07833 053749 or send an email if it’s still not cooling.
How much is an air conditioning call-out?
A diagnosis call-out is from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead. The final cost depends on the fault, the parts and the access.
Why is there ice on my air conditioning pipes?
The coil gets too cold when air cannot move across it or when the refrigerant charge is low. Check the filter first, and if it’s clean, the system needs a diagnosis.
Do you offer maintenance contracts?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is recorded, with F-Gas records where refrigerant work is involved.

Why act early in Thedden
Small faults rarely stay small. A blocked drain becomes water damage, and a slow leak drains the refrigerant until the compressor is working far harder than it should and early diagnosis normally keeps the repair simpler. Getting the date in early helps for a place like Thedden.
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before we start, with VAT shown clearly.

What the work involves, system by system
Wall-mounted split systems
On a wall-mounted split, the indoor and outdoor units talk to each other through a control cable. A break in that communication normally brings up an error code and testing finds whether it’s the cable, a board or a connection.
Condensate drains and pumps
We clear the drain, test the pump and check the fall until the condensate runs away properly. If a pump has failed, we replace it and test it before we leave.
What a customer said
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
