Is your air conditioner losing cooling power or leaking refrigerant?Sajilo Sewa offers a comprehensive AC leak test and pressure treatment package, including nitrogen pressure testing, vacuuming, and system pressure checks — ideal for new installations, AC repairs, or pre-gas refill procedures. Our technicians follow international service protocols to ensure your AC system is airtight, leak-free, and optimised for refrigerant charging. We provide service for split ACs, inverter ACs, and 1–5 ton wall-mounted units. 🧰 What’s Included in This Package? ✅ Leak Test with Nitrogen Injection High-pressure nitrogen is injected into the system to identify leaks and weak joints. ✅ System Pressure Test Monitors pressure drop over time to confirm system integrity. ✅ Vacuuming (Deep Vacuum Pull) Removes moisture, air, and contaminants from the refrigerant lines to prevent ice formation and corrosion. ✅ Valve and Joint Inspection Visual and pressure-based inspection of service valves, joints, and brazing points. ✅ System Readiness Check Before Gas Refill This package is essential before gas refilling or compressor replacement. 💬 Frequently Asked Questions (FAQs) Q1: What is the purpose of nitrogen pressure testing in AC service? Nitrogen is used to pressurize the system to detect leaks. It’s a dry, inert gas that doesn’t react with internal components, making it ideal for safe leak testing. Q2: Why is vacuuming important before gas refill? Vacuuming removes air, moisture, and non-condensable gases that can reduce cooling efficiency, cause freezing, or damage the compressor. Q3: Can I skip leak testing and just refill the gas? We highly advise against it. If a leak remains, the new gas will escape again—wasting money and harming the environment. Q4: How long does this entire procedure take? The full process (leak test + vacuuming + pressure test) takes approximately 1.5 to 2 hours, depending on system size and condition. Q5: Is this service necessary for new AC installations? Yes, vacuuming and pressure testing are mandatory steps in professional AC installations to ensure leak-free performance. Q6: Do you offer same-day service? Yes, subject to availability, we offer same-day service in Kathmandu, Bhaktapur, and Lalitpur. 📞 Book Your AC Leak & Pressure Test Service Now!
