Recharging Your AC – When and How to Recharge Refrigerant

Refrigerant is a key component of a central air system that helps move hot air out so that the AC can return cooler air back into your home. When there is not enough refrigerant, the unit is not able to cool as effectively, if at all.

Adding new refrigerant to the system, or recharging it, is the way to get the system the refrigerant it needs to get back to proper functioning. These are the few risks and concerns to be aware of during the process.

Knowing When AC Refrigerant Needs Recharged

In a closed system refrigerant should never need a recharge since it cannot evaporate. But many air conditioners will develop small leaks over time, especially in the coils that are exposed to outdoor conditions and at risk for corroding. The refrigerant will begin to leak from here until it starts to impact the efficiency of your system. Depending on the size of the leak, this can be its own problem that will need to be fixed when refrigerant is recharged.

Signs that you may have a refrigerant leak can include:

  • Hot Air in Your Vents
  • Higher Heating Bills
  • Hissing Noises as Refrigerant Leaks

Leak and low refrigerant are also some of the things that your HVAC professional will look for during an annual maintenance visit to help stop any problems before they can become worse.

Whenever low Freon is the cause of insufficient cooling, you will need a certified specialist for air conditioning recharging since there are several EPA guidelines regarding the handling of coolant.
