3 Common Commercial HVAC Problems in Boston, MA During Fall

Why Is My Commercial AC’s Refrigerant Line Icy?

June 16, 2023

If you’ve noticed that the refrigerant line of your commercial AC system is icy, it could be a sign of a significant issue. Understanding why this happens is essential so you can take the necessary steps to resolve it. Below are some of the most common causes of an icy refrigerant line and how experts in Boston, MA, can help you avoid it in the future.

Improper Installation

Poorly installed systems often have inadequate insulation or improperly sealed joints, allowing cold air to seep into the refrigerant line and cause condensation. If this occurs, icy buildup can form on the refrigerant line, restricting airflow and reducing efficiency.

If left unresolved, this problem could damage more of your HVAC system’s components. Professional repair and installation are critical since they help ensure the system works correctly without any complications.

Low Evaporation Temperature

A low evaporation temperature means the refrigerant can quickly and easily absorb heat from the air, cooling a space much more efficiently than with higher temperatures. This is because a lower temperature allows for a more significant pressure differential between the high and low sides of the system, enabling a more efficient transfer of heat.

When the evaporation temperature is too low, however, it can cause the refrigerant line to become icy. A low evaporation temperature is often due to inadequate airflow in the system. The main causes include dirty filters or problems with the indoor fan motor.

Refrigerant Leak

Refrigerant is essential for cooling air; your system won’t be able to sustain a consistent temperature if it leaks. This can cause the line to become overly cold, resulting in ice buildup. Refrigerant leaks usually occur due to aging systems or faulty components, which can be challenging to detect.

When refrigerant leaks from a heating and cooling system, it can cause a decrease in pressure, leading to reduced cooling efficiency and increased energy costs.
