Is Your Air Conditioner Showing These Signs?
You may need a gas recharge and leak repair if:
- Your system isn’t cooling or heating like it used to
- The outdoor unit pipes are freezing over
- The unit displays error codes or switches off
- You notice unusual noises
- Airflow feels weak or inconsistent
If any of the above are happening, contact Arcas immediately for inspection before the issue worsens.
What Causes Gas Leaks in AC Systems?
- Poor initial installation
- Factory defects
- Corrosion from lack of maintenance
- Rodent damage or external impact
- Moving or relocating the system
- Poor workmanship during servicing
Why It Matters: Environmental and Legal Impact
Refrigerants used in air conditioning systems are powerful greenhouse gases. If released, they can damage the ozone layer and contribute to global warming.
In the UK, under F-Gas regulations, only certified engineers can handle refrigerants. Re-gassing without leak repair is illegal and risks fines, environmental harm, and system failure.
At Arcas, all technicians are F-Gas registered, fully insured, and operate under strict environmental compliance.
