Recently, it is the peak season for home improvement. My friend asked the author, is there a charge for air-conditioning installation? In fact, there is no charge for the installation of air conditioners. However, I need to remind the friends who buy air conditioners. If the copper pipes used by the air conditioners exceed the fixed length provided by the merchants during the installation of the air conditioners, the extra part will be added. You have to pay for it yourself. Speaking of lengthening the copper pipe, then, after the copper pipe is lengthened, does it need to be supplemented with air-conditioning refrigerant?

Today, I will briefly explain to you the things that happened after the air conditioner was extended with copper pipes.

How many meters does the air conditioner need to add refrigerant after lengthening the connecting line?

  Answer:

According to the air-conditioning installation or maintenance process (national standard or industry-related standard): when the air-conditioning installation indoor and outdoor unit connecting pipeline exceeds the standard length of more than 5 meters, the refrigerant should be replenished in time. According to different pipeline specifications or air conditioner models with different cooling capacity, electronic scales are used to quantitatively add refrigerant to ensure the performance of the air conditioner (cooling and heating effect). Cooling or heating operating pressure is low, which has been affecting performance.
