- A fault code on the display

The process
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off. On site, it takes an hour or two to diagnose most faults, with the repair time depending on what we find. If a lane or gateway near Tower Hill is tight for a van, let us know and we’ll plan for it.
- You tell us the symptoms, the make and any error code.
- On the diagnosis visit, we test the electrics, airflow, drain and refrigerant.
- The fault is explained simply and the repair priced up front.
- With your go-ahead, we carry out the repair, recording any refrigerant work.
- We test the system in operation and leave you a note of the fault and the fix.
Before we arrive
- Make sure someone can let us in at the agreed time
- Make sure we can reach the consumer unit or fuse board
- Keep pets and children away from the work area

Air conditioning repair in Tower Hill, done properly
Refrigerant does not get used up, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We find and fix the leak, pressure test, evacuate and recharge to the manufacturer’s charge and write it up in the F-Gas records. If you’re dealing with a suspected refrigerant leak and new noises from the system, we can sort it out.
Around Tower Hill, repairs tend to be home systems, garden rooms and a few businesses. Describe the fault and send a photo of the unit’s label so we can plan the visit.
Any work on the refrigerant circuit is recorded: 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.

What air conditioning won’t do
Air conditioning repair cannot fix everything, and we’d rather say so up front. It does not solve:
- A power cut or a fault on the incoming supply to the building (that’s for the network operator)
- Heat gains the system was never designed for
- A discontinued model with no parts available
Not sure which it is? You can call us on 07833 053749 or drop us a line and we will tell you honestly.
Parts of the system we cover

Air conditioning repairs in Tower Hill: local notes
Roughly a third of a mile or less from central Tower Hill, you reach the Chipperfield Conservation Area. Listed buildings are part of the picture here: about 15 within half a mile of the centre, such as The Boot Public House (grade II). Should a unit ever need replacing on a listed building or in a conservation area, ask us about consent first. About 68% of households live in detached or semi-detached houses, according to the last census (2021). Tell us where your outdoor unit is and how to reach it, so we can plan the visit.
The make, model and error code are the most useful things to tell us. When cooling fails at a school like Kings Langley School, we can time non-urgent repair work around lessons.

Common questions in Tower Hill
Is Tower Hill within the area you cover?
We do. Villages and hamlets get the same service as the bigger towns. Send a few details and pictures, and we reply the same working day.
Can you do air conditioning repair in Tower Hill?
Yes. We work across London and the South East from our base in East Grinstead, and Tower Hill is part of that. To start, give us a ring on 07833 053749 or drop us a line with a few pictures.
How much is an air conditioning call-out?
Diagnosis call-outs start from £75 + VAT. Once we know the cause, you get a fixed price for the repair before any work goes ahead. The cost depends on the fault, the parts and access to the units.
Why is water dripping from my indoor unit?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and phone 07833 053749 or email us.
What can I do with an old R22 system?
Servicing with new R22 isn’t allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a leak usually makes replacement the sensible route. We’ll set out the options and quote for a replacement where it makes sense.
Do you offer an emergency repair service?
Yes, day and night. Emergencies include water coming through a ceiling or a critical room overheating, and we’ll advise on what to do right away. Call 07833 053749.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.
Before you call an engineer
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. 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.
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
