Air conditioning repair in Upper North Dean, done properly
A sealed system shouldn’t lose refrigerant, so a low charge means a leak somewhere. Topping up without a repair only delays the next breakdown. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. Typical jobs include a system that keeps cutting out and ice on the pipework or the coil, across heat pumps, wall-mounted split systems and VRF systems.
Outdoor units in a place like Upper North Dean can be near hedges and fields, so leaves, seeds and cobwebs on the coil are worth checking first.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

The Old House, listed at grade II, is one of roughly 11 protected buildings and structures in the half-mile around Upper North Dean’s centre. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.

Common questions in Upper North Dean
Is Upper North Dean in your area for air conditioning repair?
Yes, Upper North Dean is within the area we cover. To start, call us on 07833 053749 or fill in the contact form with a few photos.
Do you cover Upper North Dean for emergency air conditioning repairs?
Yes: ring the emergency line, day or night, from anywhere in Upper North Dean. Say what the system is doing and whether it shows a code, and we’ll advise on the next step.
Why is my air conditioning leaking water?
Normally a blocked or kinked condensate drain, a failed condensate pump or a unit that isn’t level. Ice that forms on the coil and melts can cause drips too. Switch the unit off and phone us on 07833 053749 or fill in the contact form.
Do I need to service the system to keep the warranty?
For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we will explain them and stick to the interval they set.
Can you set up regular servicing?
Yes. We offer maintenance contracts, set at the interval the system and the manufacturer’s terms need. Each visit is written up and F-Gas records kept where they apply.
How quickly will you reply?
On the same working day you contact us. Then we agree a date that works for you, with a fixed price before work starts.
How much does an air conditioning repair cost?
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.
When to call us in Upper North Dean
Leaks tend to start where pipes are joined: joints, valves and sections of pipe worn by vibration or damage. Coils can corrode and leak too and many leaks are slow enough to go unnoticed for a while.
Customers typically contact us when they notice one of these:
- A unit that barely blows any air
- A flashing light and a system that won’t run
- A suspected refrigerant leak
The rating label on the unit gives the model number, which helps us bring the right parts.
What your quote should include
- Whether testing, commissioning and paperwork are included
- If the quote is based on a survey, pictures or a diagnosis
- Which brand and model they’re proposing, and why
The process
We keep the work area tidy as we go, with sheets down and mess cleared as we go. Any holes, fixings or cable routes are agreed with you before we drill. The visit takes anything from an hour or so to a full day, depending on the fault and the parts. Pictures of the space and where the outdoor unit could go let us plan the work in Upper North Dean.
- 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.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- The system is run and checked in every mode, and we tell you about anything else we noticed.
Getting ready for the visit
- Make sure we can reach the consumer unit or fuse board
- Plan for pets to be kept clear during the visit
- Mention any parking restrictions near the property

How the job changes from property to property
Fans and compressors
At the centre of the system is the compressor. Before blaming the compressor, we check the electrics and the refrigerant circuit. A failed compressor often raises the repair-or-replace question, and we give you both prices.
Condensate drains and pumps
The drain is cleared, the pump tested and the fall checked until the condensate runs away properly. Failed pumps are replaced and test it before we leave.
Let and managed properties
When the building owner and the occupier are different, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.
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 arrange the inspection, get the system ready and put right anything it picks up.
A customer’s words
“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
