Refrigerant lines are insulated copper lines that transport refrigerant between your outdoor and indoor ac or heat pump units. One line transports gaseous refrigerant while the other carries liquid coolant. They are an essential part of a cooling system, as they allow the condenser and coils to transport and displace heat from your home.
Yes, refrigerant lines need to be replaced whenever you upgrade or replace your air conditioner or heat pump. Do not try and reuse old refrigerant lines, as the sealant on the lines can wear down over time. If this happens, moisture will get in and mix with the coolant, which can damage the inside of your system.
Refrigerant lines typically last 20-25 years. Any damage or contamination can shorten the lifespan of your lines, but typically that’s how long they should last. To ensure that you get the full life expectancy out of your lines, make sure you get a high-quality install from a trusted technician.
If properly installed and cared for, your refrigerant lines will last as long if not longer than the rest of your AC unit. Unless they suffer specific damage, you shouldn’t have to replace them until you replace your system entirely.
