Commercial Air Conditioning Proposal
五幸商事
If you have been using your air conditioner for over 10 years, we would like to suggest upgrading to a new model. If you are still using R22, it is likely an approximately 20-year-old model. It is a very old model, making parts replacement difficult. Additionally, R22 will be completely phased out next year. Please take this opportunity to contact our company.
