Air Conditioning Repairs & Fault Diagnosis in Birmingham & the Midlands
F-Gas certified air conditioning fault diagnosis and repair advice for domestic and small commercial split systems across Birmingham and the Midlands.
What to expect
Clear fault diagnosis before repair work is agreed.
We start with the symptoms, controls and error information, inspect the accessible system components and explain the practical repair options before further work begins.
- Discussion of symptoms, error codes and recent system behaviour
- Initial checks of controls, indoor and outdoor units
- Assessment of airflow, drainage and operating modes
- Safe F-Gas diagnostic checks where refrigerant work is required
- Clear explanation of likely causes and repair options
- Advice on repair, maintenance or replacement where appropriate
Common problems
Diagnosis for cooling, heating, airflow and drainage faults.
A system that stops cooling is not always short of refrigerant. Dirty filters, blocked airflow, control settings, sensors, condensate problems, electrical faults and outdoor-unit issues can produce similar symptoms.
We assess the complete installation rather than relying on an error code alone. The aim is to identify the likely cause safely and avoid replacing parts without proper evidence.
- Unit not cooling or heating correctly
- Weak airflow or unexpected energy use
- Water leaking from an indoor unit
- Unusual noise, odour or vibration
- Error codes or repeated shutdowns
- Controls or remote not responding as expected
Repair or replace?
Practical advice based on condition and long-term value.
Many faults can be resolved without replacing the whole system. We consider the equipment age, condition, parts availability, efficiency and repair cost before discussing the sensible options.
If replacement offers better long-term value, PGAD can survey the room, size the system correctly and provide a separate installation quotation.
Safety
Do not open refrigerant or electrical components yourself.
You can check the user controls, batteries, accessible filters and consumer-unit switches if it is safe and the manufacturer instructions permit it. Switch the system off and seek qualified advice if there is water near electrical equipment, burning smells, damaged wiring or a persistent fault.
