Step-by-Step: Our Professional Installation Process
Coolflow has a good reputation for aircon installation and repair in Welgelegen because we focus on the small things. We have a reliable installation process that makes sure your system works well for a long time.
- Site Survey and Design – We begin by checking airflow, where to put the unit, and what the building needs. We think about things like noise, sunlight, and how easy it will be to fix later.
- Copper Line Installation with Nitrogen Purging – Copper pipes move coolant between the inside and outside units. We install them carefully and use nitrogen to keep them clean.
- High-Pressure Leak Testing – After installing the pipes, we use nitrogen to check for leaks. Even small leaks can mess up the system, so we always do this.
- Vacuuming and Refrigerant Charging – We use special pumps to remove air and moisture from the lines before adding coolant. This keeps the system clean and working properly.
- Electrical Setup and Surge Protection – We put in the right-sized electrical circuits and surge protectors to protect the electronics. We also check the wiring to make sure it’s safe.
- System Calibration and Thermostat Setup – We balance the airflow, set the fan speeds, and program the thermostat for the best efficiency.
We write down, test, and double-check every step before we finish.
