What Mini Split Installation Involves
Mini split installation entails setting up a ductless heating and cooling system that delivers flexibility and efficiency. This system is made up of an outdoor compressor unit and one or more indoor air handlers. Correct installation is crucial for peak performance.
When You Need Mini Split Installation
You might consider mini split installation if you’re remodeling your home or adding an addition. It’s also perfect for homes without existing ductwork. However, if your home features a central HVAC system, mini splits may not be necessary.
The Installation Process
The installation process typically involves the following steps:
- Site assessment to determine the best locations for indoor units.
- Mounting the indoor air handlers on the wall.
- Installing the outdoor compressor unit on a stable surface.
- Running refrigerant lines and electrical wiring between the units.
- Testing the system to ensure everything works properly.
The entire process usually requires about 4 to 8 hours, depending on the complexity of the installation and the number of units being installed.
Tools and Standards
Installers typically use tools such as refrigerant gauges and screwdrivers. It’s important to follow local building codes and standards, such as those set by the Air Conditioning Contractors of America (ACCA).
