Does Your AC Need Freon Recharge?

It often seems as though there is a never-ending list of components in an HVAC system. So many pieces have to work together to keep everything running smoothly. And one of the most critical HVAC system components is freon. Freon is the cooling agent, also known as the refrigerant, that is used in most air conditioning systems today. A cooling agent is needed to remove the heat from the air indoors and distribute the remaining cool air through the house. Freon takes on this crucial job. 

In this article, homeowners can learn more about freon's benefits in an AC system, the common problems that it can have, and when homeowners should consider freon recharge services.

AC Problems from Low Freon

Because freon plays such a critical role in the functionality of an AC system, if the freon starts to run low, it can spark all sorts of problems.

  • Inefficient cooling: Freon removes heat from the air. If the AC system is low on freon, it will take longer to remove the heat and cool the house. 
  • Ice buildup: Low levels of freon mean lower pressure in the AC system, and that lower pressure causes lower temperatures that could freeze the evaporator coil.
  • Unusual hissing noises: One of the most common causes of AC systems running low on freon is a leak. Because of the high pressure in refrigerant lines, there is often a loud hissing noise that will start when a leak occurs.

Homeowners should always pay attention to these signs to resolve any problems as soon as they pop up.

The Many Benefits of Freon

Every AC unit requires a refrigerant to cool the air in a home, and the most common refrigerant is freon (also referred to as R-22). The AC unit has a series of coils and compressors. The unit will first compress freon gas, causing it to heat up. The heated freon gas then moves through the various coils in the system, which then cools it down to liquid form. This cooled, liquid freon can then absorb the heat from the air leaving the conditioned air that circulates the house allowing everyone in the home to stay cool and comfortable. 

Freon has remained a long-used and well-trusted refrigerant to keep the AC system running smoothly and efficiently. However, as mentioned, freon can cause problems for an AC unit from time to time. Homeowners must regularly service their AC unit, checking the freon levels to ensure everything is running as it should. 

When to Consider Freon Recharge ServicesCartoon AC Repair Technician

A freon recharge is simply the act of refilling the freon in an AC unit. Over time, freon will start to run low, slowing, or stopping the removal of heat from the air. Refilling their freon allows homeowners to keep the AC system running efficiently so they can continue to experience the cool and comfortable air they need.

However, homeowners should not attempt to recharge freon on their own. Freon is a toxic substance that can become lethal if not handled correctly. For homeowners to protect their safety and the safety of those around them, it's best to contact an HVAC professional to handle the situation.
