Refrigerant Blends. These air conditioner refrigerant are also known as "azeotropic" and"zeotropic". Their use is increasing as they are environmental friendly. The setback is that the total air conditioning systems production cost is higher. However, as more manufacturers switch to this type of refrigerants, the cost/unit will drop eventually.


Until a few years ago, many air conditioners sold in the United States used the refrigerant chlorodifluoromethane, usually referred to “R-22.” R-22 is one of a number of gases marketed under the brand name Freon, and has been commonly used as a coolant in air conditioners, heat pumps, and other appliances.


Refrigerants give your air conditioner the power to cool your home, but many homeowners treat them as an afterthought when shopping for a new AC unit. After all, it’s easy to overlook the type of fluid pumping through your AC when compared to factors like energy efficiency that have a clear price attached. However, as environmental regulations phase out older refrigerants and lead to newer ...


Refrigerants are what make air conditioning possible. Contained within the coils of an air conditioner, these liquid agents cool and dehumidify indoor air. For years, the most common refrigerant used in air-conditioning systems was R-22. In response to growing environmental concerns, production of systems using R-22 refrigerant is being phased out.


A working air conditioning system is essential to a comfortable ride, but an AC unit won't work without AC refrigerant, R134a. R134a is pumped through the AC system to the evaporator, where cabin air condensates. This condensation allows the cabin air to exchange heat with the refrigerant. It also dehumidifies the air for optimal comfort.


By January 1, 2010, there was a ban on the production and import of R-22. 5 As a result, manufacturers of heat pump and air conditioning equipment redesigned their systems to accommodate R-410A, a chlorine-free refrigerant compared to R-22. The refrigerant would soon replace R-22 in the new HVAC equipment.


For decades, Freon, also known as HCFC-22 and R-22, was the main refrigerant chemical used in residential air conditioning units and heat pumps. To help protect the ozone layer, the EPA has mandated that the production of Freon be stopped by January 2020. The good news is that new air conditioning systems made since 2010 no longer rely on Freon.


Residential Air Conditioner Freon Refill Cost. Freon costs an average of $150 for a Freon refill. Most people pay between $100 and $350 for a refill, depending on the size and type of your HVAC unit. Older large r22 units can reach $600 or more. A 25lb jug of r410a runs $75 to $175.Labor adds an average $70 per hour. “Freon” is simply a brand name owned by DuPont chemicals.


Freon is the cooling agent used in most air conditioning systems. Every air conditioning system needs a refrigerant (also called a coolant) that actually creates the cool air -- that's the role of Freon. As necessary as Freon is to the optimal performance of your your air conditioner, you do not want to handle a potential Freon problem yourself.


Low refrigerant means low pressure and low pressure means low temperatures that will eventually freeze something called an evaporator coil. When the evaporator coil freezes, cold liquid refrigerant flows through the refrigerant line, causing the surrounding moisture in the air to freeze. So that’s why the refrigerant line has ice on it.
