As you might expect, copper refrigerant agent lines need to be changed out whenever you are replacing an AC system or mounting a brand-new one. However, it is additionally crucial to keep in mind that copper refrigerant lines are recommended to be transformed out when upgrading your air conditioning system. It can be appealing to recycle old copper refrigerant lines after a system upgrade, however it is not generally a good idea. In order for a copper line to work effectively, it needs to be totally dehydrated. An old copper cooling agent line may not be sufficiently free from moisture. Because of this, any kind of moisture in the line will certainly integrate with the cooling agent to develop an acid, which can harm the compressor electric motor.

Cooling Agent Lines

These are the metal (normally aluminum or copper) tubes that move the fluid to the evaporating coil and back to the condensing system. It is a part of the air conditioning. This unit is mounted by cooling and heating specialists outside of your home and full of refrigerant gas. When the cooling agent cools down to a liquid by temperature exchange with the outside air, the condensing system pumps the fluid to the evaporator coil to be evaporated into a gas once again.

You may additionally need to replace your copper cooling agent line in case of leaking. A sure sign of a refrigerant line leakage is an oil discolor, because oil moves in the cooling system along with the refrigerant. It continues to be noticeable after the refrigerant has steamed off. A few of the most usual sources of leaks include:

  • Mechanical damage. When exterior copper cooling agent lines are damaged or worn over time by lawnmowers, subjected to severe weather condition, or stepped on by children or workers, it can create a leakage.
  • Deterioration. If the copper refrigerant line is revealed to contaminants, it can lead to deterioration as well as succeeding leaks. This could occur through straight contact with ductwork or other different metals, or it might arise from exposure to a destructive ambience from chemical storage space or furniture refinishing
  • Settling Over Time. When the structure or the condenser settles, it puts tension on the copper refrigerant agent lines, making leaks more likely.

Eventually, a leaky line can minimize the expected quality of the performance of your air conditioning system, so it is vital to solve the trouble as quick as it’s found.

Why Replace Your Lineset When Replacing AC/HVAC?

Linesets for HVAC or AC systems are copper piping that is used to carry cooling agent from the outdoors condenser to the evaporator coil inside and repeats this process in a loop-cycle. Consequently, linesets are needed and essential for mini-split HVAC/AC units or systems to run. More recent HVAC and air conditioner units use R-410 cooling agent, while older systems use R-22 refrigerant. R-22 cooling agent is presently being phased out by the U.S. Environmental Protection Agency since it has chlorine which can add to ozone depletion throughout a leak. As a result of this, those that are changing an old HVAC device will require a brand-new lineset to utilize the R-410 cooling agent.

R-22 or R-410 Refrigerant?

The distinctions among these cooling agents do not stop at the use of chlorine. Cooling agents likewise include different oils which do not blend well with each other. For instance, R-22 has a mineral oil which does not blend with POE oil, which is within R-410 refrigerant for modern air conditioning devices.

When an R-410 cooling agent is used with a lineset that used R-22 at one time, this can cause damages to the whole system and decrease the lifespan of the exterior compressor and system as a whole. Consequently, utilizing a new lineset protects against the possibility of refrigerants being mixed. While old linesets that held R-22 can be flushed, evidence has shown that flushing an R-22 lineset for HVAC systems does not get rid of all the oil residue, which can cause system failures in the future. This implies that a brand new lineset is the best idea for a technician when mounting a brand-new heating and cooling system and replacing an old one.
