When a new air conditioner starts leaking, something went wrong with the installation.
❌ Water or gas leaks are not normal and are almost always linked to technical faults, inadequate materials, or lack of care in execution.
If you want to avoid headaches right after purchasing the unit, pay attention to these fundamental tips.
1️⃣ Hire a Specialized Installer
The first and most important step is to choose a qualified professional.
👨🔧 An experienced technician:
✔️ Follows correct installation standards
✔️ Uses appropriate tools
✔️ Makes well-sealed connections
✔️ Performs safety tests
Often, the cheap option ends up being expensive when the installation isn't done by someone who understands the process.
2️⃣ Use Quality Materials
The quality of materials makes all the difference in the final result.
🔩 Copper pipes
🔧 Connections and flanges
🧊 Thermal insulation
🔗 Clamps and supports
Inferior materials can cause cracks, corrosion, and joint failures, leading to refrigerant gas or condensate leaks.
3️⃣ Vacuum the Piping Correctly
Vacuuming is an essential step and should never be ignored.
🌀 It removes:
✔️ Moisture
✔️ Air
✔️ Impurities from the piping
When vacuuming is poorly done, the system loses efficiency, the compressor works harder, and leaks can appear over time.
4️⃣ Check Connections, Flanges, and Welds
Most leaks occur at the joints between pipes. 🔍 Therefore:
✔️ Connections must be tightly secured
✔️ Flanges must be well-made, without cracks
✔️ Welds must be free of pores or imperfections
After installation, it is ideal to perform a leak test with nitrogen, capable of identifying even micro-leaks invisible to the naked eye.
5️⃣ Install the Drain Correctly
The drain is responsible for conducting condensation water.
💧 If poorly installed, it can cause:
❌ Internal dripping
❌ Stains on the wall
❌ Infiltration
✔️ The drain must have the correct slope
✔️ Be free of bends
✔️ Not present any obstructions
6️⃣ Perform Tests Before Finalizing the Installation
Before authorizing the service, it is essential to test the system.
🔧 Important Tests:
✔️ Equipment Functioning
✔️ Checking for bubbles with soapy solution at connections
✔️ Observing possible water leaks
These tests ensure that the air conditioner was installed correctly.
✅ Conclusion
Preventing leaks in new air conditioning installations depends on three main factors:
✔️ Professional execution
✔️ Quality materials
✔️ Attention to technical details
When the installation is done well from the start, the equipment works efficiently, safely, and durably, avoiding unnecessary problems and expenses.
👉 Investing in a good installation guarantees peace of mind for many years.
