How we handle air conditioning repair in Wallingford

We treat a faulty system the way a doctor treats a patient: diagnose the cause, treat it properly and sign it off when it’s working. Guessing is expensive, and topping up refrigerant on a system with a blocked filter fixes nothing. Typical jobs include a unit that won’t start and new noises from the system, on ducted systems, VRF systems and multi-split systems.

Outdoor units around Wallingford often sit near hedges, trees and lawns, where leaves and cuttings can clog the coil and cut the cooling. We check the coil early on.

Whatever the visit, you get a written record: commissioning details for an installation, a fault and repair note for a repair, or a record of the service. File it with the manual so it’s to hand next time.

Keeping the system healthy

Looking after it is simple, and it makes the next visit easier:

  • Check the filter, the mode and the set temperature before calling us
  • Switch the unit off if water is leaking from it
  • Write down the fault code if there is one

After the repair, the system is run and checked in every mode it has. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.

Filter cleaning is the simplest prevention there is. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips, so keep them clean as the manual describes.

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.

Ducted and cassette systems

With ducted and cassette units, most of the system is hidden in the ceiling, so access matters. Condensate pumps are common on both, and a failed pump is a frequent cause of water leaks.

Common questions in Wallingford

Who do I call if my air conditioning fails in Wallingford out of hours?

Yes: ring the emergency line, day or night, from anywhere in Wallingford. Have the make, model and error code ready, and we’ll talk you through what happens next.

Will you come out to Wallingford?

Yes. Wallingford is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.

Is there a survey before the work?

Yes. For simple jobs, photos and a few details can be enough, while larger systems and faults that need testing are seen on site.

Can you set up regular servicing?

Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.

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.

My system uses R22. Can it be repaired?

Most of the time, we recommend replacement. New R22 can’t be used to service systems, and parts for older units are getting harder to find, so we will quote for a modern replacement and explain why.

Why isn’t my air con cooling?

There are several possible causes, from simple to serious. We read any fault code and test the system to find which and you get a fixed price before the repair.

When something else is needed

Not every problem is solved by air conditioning repair, and we’ll tell you before we start. It won’t put right:

  • A discontinued model with no parts available
  • A power cut or a fault on the incoming supply to the building (that’s for the network operator)
  • A unit that was never big enough for the room

Not sure which it is? You can phone 07833 053749 and we will tell you honestly before booking.

The make, model and error code are the most useful things to tell us. If a system fails at a school such as Fir Tree Junior School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

How the visit works

On the day, we arrive at the time agreed with you and run through the plan before anything else. Floors and furniture near the work are covered with dust sheets, and anything electrical is made safe before work starts. On site, it takes a single visit for many faults, while some repairs need a second visit once parts arrive. Send pictures of the space and the outside wall, and we can plan the work near Wallingford.

  1. You describe the fault, the make and any error code, ideally with a photo.
  2. We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
  3. Once the cause is found, we explain it and fix the price for the repair.
  4. The repair is carried out, and any refrigerant work is leak tested and recorded.
  5. We run the system, check it’s working properly and note anything else that needs attention.

How to prepare

  • Keep pets and children away from the work area
  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Mention any parking restrictions near the property
