Every devices or appliance you usage is do of various materials that are critical to its functioning. Even if one component is damaged or start to have actually some problem, her appliance or equipment will not have the ability to perform the role for which the is made properly. Similarly, your HVAC system has countless components, one of which is the refrigerant line. The refrigerant heat is responsible for the circulation of the refrigerant, which eventually absorbs and also releases the heat and also makes the air cool. But sometimes, the refrigerant heat may become damaged and/or begin leaking, affect the functioning of her system. Below we will comment on some common reasons of HVAC refrigerant line leaks in detail, to give you a appropriate understanding the the problem.

Purpose that HVAC refrigerant line

Refrigerant is just one of the an easy things important for one HVAC to duty properly. The is a blend of chemicals the circulate within her air conditioner. The refrigerant transforms from liquid to gas if circulating v your system and also absorbs and also releases heat during the process. The refrigerant lines administer a passageway to the refrigerant because that circulation. The refrigerant lines are a mix of two copper currently that offer the purpose of connecting the condenser and also evaporator coil.

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

These are few of the ideal refrigerant leak detectors for you:

Causes that refrigerant heat leaks

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

There deserve to be various reasons for leaking refrigerant lines, yet let us have actually a look at at some common reasons of HVAC refrigerant heat leaks.

Pinhole leaks:

Formaldehyde is a common aspect found in home structure products and it naturally creates ‘formic acid’. As soon as the formaldehyde accumulation on the copper lines, it forms formic acid which progressively eats away the copper lines and also creates pinhole leaks. This commonly happens after making use of the HVAC mechanism for a long time. Together with the copper lines, the formic mountain formation also affects the components of the system. Manufacturers have started replacing the copper lines v aluminum as they are not prone to corrosion.

System vibration:

The exterior unit that the HVAC device is consisted of of a compressor and also condenser. The compressor has a an effective motor and fan unit housed within a metal cabinet and the motor functions all the time the system is on. While running the motor renders vibrations yet if the system is set up properly, a vibration isolator is attached to the system. These vibration isolators absorb any kind of excess movement and also keep the vibrations indigenous circulating through the system. But, in case the HVAC is not mounted properly and also there is no vibration isolator attached to the system, the engine can cause severe vibrations when working. These vibrations can weaken or even fracture the refrigerant lines. In some cases, the clamps ~ above the copper refrigerant lines deserve to become loose causing them come rub versus the system’s strut. These continual rubbings kind holes in the unit, resulting in the refrigerant lines to leak.

Line collection damage:

There are opportunities that the copper refrigerant present connecting the condenser and the evaporator coils room pierced or damaged leading to it to leak. The causes of such damages can it is in lawn mowers, building work, who tripping end the line set, or penetration by pond and/or screws driven into the walls of the structure if ideal protective actions are no taken.


Some lot of formaldehyde is existing in the at home air of virtually every residence which, over some time, creates corrosion well-known as Formicary corrosion. Formicary corrosion is a an outcome of formic acid generated naturally by formaldehyde. This corrosion can assault the refrigerant lines make of copper, at some point resulting in refrigerant leaks in ~ several locations throughout the HVAC system. Even in the case of the heat pumps, the accumulators that space made that steel begin to corrode or rust after being offered for some years, bring about refrigerant leaks.

The refrigerant lines begin to leak one of two people after an extensive use or because of a absence of ideal prevention. The refrigerant leak is a serious and dangerous matter and should not be taken lightly. The biggest difficulty with the leaking refrigerant heat is that you will should recharge the refrigerant more frequently, and also it is an expensive component. Also, if the concern of leaking refrigerant is not faced properly ~ above time, that will result in high energy bills and also increased fix or company charges. So, whenever you notice leakage from her HVAC system, call an professional at the earliest together if left unattended, this leakage can cause permanent damages to your system.
