Commercial HVAC Refrigerant Leak: What should you know?

A commercial HVAC system is comprised of multiple components, some of which are stagnant while some tend to move. The HVAC refrigerant is one such component that helps in efficient cooling of your commercial HVAC units. This refrigerant tends to cycle through your appliance and helps render a cooling effect while passing through the ducts. Given the fact that a refrigerant is what essentially helps your HVAC system, it is important that you get it checked frequently. Get in touch with a local commercial HVAC repair near me to make sure everything works fine.

What is a refrigerant?                              

In simple terms, a refrigerant is the fluid mixture which is used in combination with the heat pump present inside the HVAC unit. Throughout the cycle of refrigeration, the refrigerant tends to transition all the way from a dense liquid to cooling gas that runs through the pipes. Without the presence of this substance, it can be practically impossible for the HVAC systems to cool hot air present inside the room. Services for commercial HVAC repair near me will help you understand the necessities of refrigerant in your HVAC system.

Top Refrigerant Variants

The commonly used refrigerants used in the HVAC system over the course of time include:

  • Chlorofluorocarbons (CFCs) (Including R12):

This particular variant of refrigerant was known to contribute the most to greenhouses gases. The production for new stocks was banned in the year 1994.

  • Hydrochlorofluorocarbons (HCFCs) (Including R22):

It is comparatively less damaging for the environment as well as the ozone layer. However, the EPA has yet mandated the phase out session for this refrigerant under the 2010 Clean Air Act. R22 shall phase out totally by the year 2020.

  • Hydrofluorocarbons (HFCs) (Including R134 and R410A):

With no presence of chlorine in this mix, it has been rendered a safer option for environment. It is now being used as a replacement for R22. HVAC units that operate on the R410A tend to cater better quality of air, efficient working, as well as increased comfort.

Top 5 recognizable signs of HVAC Refrigerant Leak

If there has been a significant depletion of refrigerant levels, it shall take longer for your commercial space to cool down. This can result in frequented visit to the HVAC system’s thermostat for the adjustment of downward temperature. You can confirm the loss of refrigerant by seeking help from commercial HVAC repair near me.

  • Frozen Coils:

When the level of refrigerants in the evaporator coils isn’t sufficient, the coil might not absorb the heat adequately. This shall result in condensation atop the coils which eventually lead to freezing. At times, this frozen condensation might start to melt off and drip upon the floor.
