Aircon Pressure Test Services Singapore.
A pressure test is the single most important step in aircon installation or repair. At Aircon Servicing & Repair Singapore, we perform proper nitrogen pressure testing to SS 553 standards on every installation and as an independent verification service. We test, hold for the full 24-hour duration, document all readings, and issue an official signed certificate.
5 Situations Making Pressure Testing Non-Negotiable
Skipping this test risks continuous refrigerant leaks, wasted gas top-ups, and expensive ceiling damage. Here is when you must get tested.
New Installation Handover
Holds nitrogen at high pressure for 24 hours minimum before charging refrigerant. Ensures joints are sound before wasting expensive gas.
Essential for new setups →After Brazing or Flare Work
Opening the refrigerant circuit introduces leak risks. A pressure test post-repair is the only way to confirm work integrity.
Independent repair verification →After a Refrigerant Leak
Re-charging without finding the leak is pointless. We isolate and find the exact leak section before refrigerant is added.
Stops continuous gas loss →Pre-Handover Inspection
For new condos & commercial units. Verify pipework integrity independently to prevent years of mystery top-ups later.
Condo & commercial handover →MCST & Warranty Disputes
When installers claim "no leak" but gas keeps disappearing, our signed 3rd-party certificate ends arguments effectively.
Dispute resolution certified →Official SS 553 Certification
We document start/end pressures, ambient temperature corrections, and vacuum micron readings for absolute compliance.

Aircon Pressure Test in Singapore — Nitrogen Tested, Certificate Issued.
A professional aircon pressure test is the single most important step in any installation or major repair, yet it is often skipped. Failing to test pipework properly before charging refrigerant leads to hidden leaks, causing recurring gas loss, poor cooling, and unexpected top-up expenses. At Aircon Servicing & Repair Singapore, we conduct rigorous nitrogen pressure testing following Singapore’s SS 553 standards. We carefully document every reading and issue an official, signed pressure test certificate to guarantee your system is completely sealed and safe.
A proper pressure test is never a quick 10-minute job; a full, compliant test takes between 26 to 28 hours. Our certified technicians recover existing refrigerant, pressurize the pipework using Oxygen-Free Nitrogen (OFN) in three distinct pressure stages, and hold it for a full 24 hours. We log start/end pressures and factor in ambient temperature corrections to detect even the smallest hairline leaks. If a drop occurs, we locate the leak using electronic leak detectors and soap solutions, perform the necessary repairs, and re-test before vacuuming and issuing your certificate.
Pressure testing is essential after any brazing or flare work, following a major leak repair, or before handing over new HDB, condo, or commercial units. It also serves as independent proof for developers, MCST committees, and warranty disputes when resolving persistent leakage claims. Whether you manage a residential split system or a large commercial VRV/VRF setup, our pressure testing saves you thousands of dollars over the lifetime of your aircon by eliminating slow, ongoing refrigerant leaks early on.
While a pressure test provides absolute certainty that your refrigerant pipework is 100% sealed, we remain fully transparent about what it covers. A passed test confirms pipe integrity, but it does not diagnose compressor health, electrical wiring issues, or drainage blockages. For complete peace of mind, we offer combined diagnostic packages alongside pressure testing so you have a complete, honest assessment of your entire cooling system’s health.
We take pride in delivering thorough, engineering-grade work rather than rushed shortcuts. Our official test certificates are recognized by MCSTs, property developers, and insurance assessors for handover and warranty purposes. If another contractor recently repaired a leak and you want independent verification, or if you suspect your original installation cut corners, our experienced team provides reliable testing to give you true confidence in your setup.
