About our air conditioning repair in Ash
Any repair we carry out in Ash starts the same way: fault codes, electrics, airflow, drain and refrigerant are all checked. After that, you get a plain explanation and a fixed price for the repair. The work covers heat pumps, VRF systems and ceiling cassettes, and people most often call us about frost on the pipework and a system that won’t switch on.
Around Ash, most of our repairs are in homes, with some small businesses. What you tell us about the fault shapes the visit, so describe what it’s doing and send a photo of any error code.
Aftercare is simple, and most of it is in the manual: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. It also keeps you on the right side of any warranty terms that ask for servicing.

The process
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. The work 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 Ash.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- We diagnose on site, checking the codes, electrics, airflow, drain and refrigerant pressures.
- Once the cause is found, we explain it and fix the price for the repair.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- We run the system, check it’s working properly and note anything else that needs attention.
Preparing for the visit
- Mention any roof access, ladders or high-level work
- Tell us about any building rules, permits or sign-in
- Have the make and model of any existing unit to hand

What the work involves, system by system
Fans and compressors
Fan motors and bearings wear over time, and the first sign is often noise or weak airflow. Indoor and outdoor fan motors can usually be replaced, depending on parts availability.
Circuit boards and sensors
Boards and sensors are the system’s nervous system. Sensor faults can stop the system or confuse it and boards can fail with age or after electrical problems.
