The perforation characteristics of central air conditioning need to be strengthened. Who should I deal with?

The property itself has a corresponding business, but through the reinforcement of the property, the price is generally higher.

I suggest that you find the corresponding practitioners to complete the strengthening according to your own needs.

When installing central air conditioning, holes shall not be punched in the bearing beams or columns of buildings. Punching holes in these load-bearing structures will lead to the deterioration of the overall strength of the building. If holes have been punched, necessary measures should be taken to make up for the mistakes.
