To ssey trainet, attend refresher traing every few years, expericially when new frigerants or regulations are introduced.

Conclusion

Ini adalah proses pemulihan yang baik untuk para ahli yang bekerja sama dengan profesional HVAC. Ini adalah keamanan keamanan lingkungan, perlindungan teknik dari para pengguna awal yang tidak stabil, dan memastikan bahwa mereka tidak akan membiarkan perusahaan lain melakukan hal-hal yang sama lagi.
