Low refrigerant isn’t something an AC system “uses up”

Your air conditioner operates as a closed system, so refrigerant should not regularly disappear. If the level is low, there may be a leak that needs to be located and properly addressed—not simply refilled without investigating the cause.

John Brown Heating & Cooling can evaluate your system and explain your repair options clearly.
