PuronAlmost all systems we now install use Puron, the environment-friendly refrigerant. It won’t be long until all systems are required to use this type of refrigerant. If you are considering replacement, it does not make sense to install a system that uses R22 Refrigerant, a refrigerant that will soon be obsolete. At Brody-Pennell we have installed more Carrier Puron high-efficiency systems than any other contractor serving Los Angeles area.
