Does My Aircon Need To Be Re-Gassed?

Air conditioning systems play a crucial role in maintaining indoor comfort, especially during the hot summer months.

However, over time, an air conditioner may require maintenance, including recharging the refrigerant. In this blog post, we will explore the signs that indicate an air conditioner may need to be recharged and why proper refrigerant levels are essential for its optimal performance.

Understanding the Role of Refrigerants:

Refrigerant is a vital component of an air conditioning system. It is responsible for absorbing heat from indoor air, cooling it down, and then releasing the heat outside. Refrigerant operates in a closed loop, continually cycling through the system. It does not get used up or consumed under normal circumstances, However, if there is a leak, the refrigerant level can decrease, impacting the system’s cooling capacity.

Decreased Cooling Performance:

A noticeable decline in cooling performance is one of the primary signs indicating the need for an air conditioner to be re-gassed. If the air conditioner is blowing warm air or if it takes significantly longer to cool the room, it could indicate low refrigerant levels. Insufficient refrigerant hampers the system’s ability to extract heat effectively, resulting in reduced cooling capacity.

Increased Energy Consumption:

Another indicator of low refrigerant levels is a sudden increase in energy consumption. When refrigerant levels are inadequate, the air conditioner needs to work harder and run for more extended periods to achieve the desired temperature. This extra strain on the system leads to higher energy usage and, consequently, increased utility bills.

Ice Formation on Coils:

If you notice ice forming on the evaporator coils of your air conditioner, it could be a sign of low refrigerant. Insufficient refrigerant flow causes the evaporator coils to become excessively cold, leading to the formation of ice. Ice buildup restricts airflow and further reduces the system’s cooling efficiency.

Hissing Sounds or Refrigerant Odor:

If there is a refrigerant leak in the system, you may hear hissing sounds near the indoor or outdoor unit. Additionally, some refrigerants have a distinctive odor, so if you notice a chemical smell around your air conditioner, it could indicate a leak. In such cases, it is crucial to turn off the system and contact a professional HVAC technician for inspection and repair.

Professional Evaluation:

It is important to note that assessing and recharging refrigerant levels is a task best left to qualified professionals. HVAC technicians have the necessary tools and expertise to diagnose refrigerant issues accurately, identify leaks, and recharge the system as needed. Attempting to handle refrigerant without proper training can be hazardous and may also void the manufacturer’s warranty.


Proper refrigerant levels are essential for the optimal functioning of an air conditioning system. If you observe a decline in cooling performance, increased energy consumption, ice formation, or suspect a refrigerant leak, it may be time to have your air conditioner re-gassed. Contact a licensed HVAC company, like All-Temp Services, to assess your system, identify any leaks, and recharge the refrigerant to restore your air conditioner’s efficiency and performance. Regular maintenance and timely recharging of refrigerant will help ensure that your air conditioner continues to provide reliable cooling comfort for years to come.
