Every tools or appliance you usage is do of various contents that are crucial to the functioning. Also if one ingredient is damaged or beginning to have actually some problem, your appliance or devices will not have the ability to perform the duty for which that is make properly. Similarly, her HVAC mechanism has numerous components, among which is the refrigerant line. The refrigerant heat is responsible for the circulation the the refrigerant, which at some point absorbs and also releases the heat and also makes the waiting cool. Yet sometimes, the refrigerant heat may become damaged and/or start leaking, affect the functioning of your system. Below we will discuss some common causes of HVAC refrigerant line leaks in detail, to give you a suitable understanding the the problem.

Purpose the HVAC refrigerant line

Refrigerant is one of the straightforward things essential for an HVAC to role properly. It is a mix of chemicals the circulate within your air conditioner. The refrigerant transforms from fluid to gas when circulating with your system and absorbs and also releases heat during the process. The refrigerant lines provide a passageway to the refrigerant because that circulation. The refrigerant lines room a mix of 2 copper lines that offer the function of connecting the condenser and evaporator coil.

The larger line, also called the suction line, dead the cool gas and also is insulated come prevent any kind of condensation and additionally increase efficiency. The larger line is also known as the vapor heat or the return line. The smaller sized line carries heat liquid and is uninsulated. This smaller sized line is mostly well-known as the fluid line.

These are several of the best refrigerant leak detectors for you:

Causes the refrigerant heat leaks

A damaged or leaking refrigerant heat can cause increased power usage, higher bills, and also inefficiency of her system. If not repaired immediately, the can reason permanent damages to your system. The leaking refrigerant heat is responsible because that the regular loss the refrigerant, prompting repetitive recharge and also the refrigerant price is spiking regularly.

There have the right to be assorted reasons for leaking refrigerant lines, but let us have a look at some common causes of HVAC refrigerant line leaks.

Pinhole leaks:

Formaldehyde is a common element found in home structure products and it naturally forms ‘formic acid’. As soon as the formaldehyde accumulation on the copper lines, it develops formic mountain which gradually eats far the copper lines and creates pinhole leaks. This normally happens after utilizing the HVAC system for a long time. In addition to the copper lines, the formic mountain formation also affects the components of the system. Manufacturers have started instead of the copper lines v aluminum together they space not prone to corrosion.

System vibration:

The exterior unit of the HVAC device is made up of a compressor and also condenser. The compressor has actually a powerful motor and fan unit housed within a metal cabinet and also the motor functions all the moment the system is on. While running the motor provides vibrations yet if the device is mounted properly, a vibration isolator is attached come the system. This vibration isolators absorb any excess movement and also keep the vibrations from circulating v the system. But, in instance the HVAC is not mounted properly and there is no vibration isolator attached come the system, the motor can reason severe vibrations while working. These vibrations can weaken or even fracture the refrigerant lines. In some cases, the clamps top top the copper refrigerant lines have the right to become loosened causing them come rub against the system’s strut. These continuous rubbings type holes in the unit, causing the refrigerant lines to leak.

Line set damage:

There are opportunities that the copper refrigerant lines connecting the condenser and also the evaporator coils space pierced or damaged leading to it come leak. The reasons of such damages can be lawn mowers, building and construction work, someone tripping end the heat set, or penetration by pond and/or screws driven right into the walls of the building if ideal protective procedures are not taken.


Some quantity of formaldehyde is current in the indoor air of almost every home which, over part time, creates corrosion well-known as Formicary corrosion. Formicary corrosion is a result of formic acid generated naturally by formaldehyde. This corrosion can assault the refrigerant lines made of copper, ultimately resulting in refrigerant leaks in ~ several locations throughout the HVAC system. Also in the instance of the heat pumps, the accumulators that room made of steel start to corrode or rust ~ being provided for part years, bring about refrigerant leaks.

The refrigerant lines start to leak one of two people after lengthy use or due to a absence of ideal prevention. The refrigerant leak is a serious and dangerous matter and should not be take away lightly. The biggest problem with the leaking refrigerant heat is that you will must recharge the refrigerant much more frequently, and it is an high value component. Also, if the problem of leaking refrigerant is not encountered properly top top time, that will an outcome in high energy bills and also increased repair or service charges. So, at any time you an alert leakage from her HVAC system, contact an expert at the earliest as if left unattended, this leakage can cause permanent damage to her system.
