Air conditioning vacuum test
A vacuum test is crucial for ensuring your air conditioning system is leak-free and performs efficiently. It prepares the system for optimal refrigerant charge and reliable operation.
Air conditioning vacuum test
If your air conditioning system is underperforming, has recently had components replaced, or needs a new refrigerant charge, a vacuum test is essential. It's a key diagnostic step before adding refrigerant to prevent future issues and ensure system integrity.
Our engineers will evacuate all air and moisture from your AC system using a specialist vacuum pump. This process creates a deep vacuum, which not only removes non-condensable gases but also boils off any residual moisture. They'll then monitor the vacuum level for a specified period to detect any pressure rise, indicating a potential leak.
