No Cool Air Coming Out The Vents
This problem can occur even when the air conditioner (or condensing unit) is running outside. It’s important to clarify that the term air conditioner is referring to the outdoor unit. It’s entirely possible for the indoor furnace to circulate air without the outdoor unit kicking on. This is a common problem but not what we’re trying to address in this blog. Our concern today is why the air conditioner can operate but not produce cool air from the ducting system. This is most likely to occur when the air conditioning system is low on refrigerant. R22 and R410A refrigerants serve as the heat removal agent in a cooling system. When a system becomes low on refrigerant, it immediately loses cooling capacity. That is why the system can appear to be running as it normally would but the air isn’t being cooled.
If you experience this inconvenience you’ll need to either add more refrigerant or replace what’s leaking. Step one is to call for a professional technician to determine how low your system is operating. From there, the option of repair vs. replacement can be considered in more detail.
