I work in the central air-conditioning sales department. People obviously want to do central air conditioning. You called him, but he said no. What can I do to open this breakthrough?

Generally, the central air conditioning required by the owners has been booked before the renovation, or the decoration company has approached the water tower to do this industry. It is not good to communicate directly with the decoration company. Many owners are used to listening to the decoration company or advertising more. Isn't it very popular to open a shop online? People who sell central air conditioners can go to the 58 air conditioning network for free, so it is much better for the owners to find their own doors than to find them abruptly?
