While we still service HVAC equipment using Freon, most residential HVAC units are now using Puron® or R-410A, a type of hydrocarbon refrigerant without the chlorine. The reason for the switch was to reduce the impact that the gasses have on the ozone layer and the environment.
As Freon was phased out, new HVAC systems began using a refrigerant known as Puron® or R-410A, an HFC. More efficient and less harmful to the environment, R-410A has been in use since its introduction in 1996 and is found in most of today's modern HVAC systems.
In 2010, the EPA passed the Clean Air Act, outlawing its use in new devices. As such, new AC systems generally use one of the following types of refrigerants: R-410 (Puron): Most air conditioners produced between 1996 (when scientists invented it) and 2020 use Puron.
Freon is no longer used in new AC units.
Yes, production of R22 was banned years ago. But existing stocks of R22 are available and can still be legally sold and used. Some hvac companies recover R22 from old systems they're replacing and save it to use in other units.
Freon MO99 is the closest capacity match to R-22 compared with most other no-oil change refrigerants. What does this mean to my residents? Choosing an energy-efficient blend with a mass flow rate within 10 to 15% of R-22 helps reduce energy costs and shorten the system's downtime.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
R-454b Will Be the New (New) Refrigerant Starting January 1st, 2023. In 2010 when I started my venture into the HVAC industry, I was coming in during a time of transition. Our industry was changing from systems that had R-22 refrigerant circulating through their lines to R-410a.
The refrigerant that new AC units use works better and are less likely to damage our atmosphere. On top of this major change, modern AC units are generally built to be more energy efficient than their older counterparts. This saves you money on energy bills and keeps CO2 out of the air.
As mentioned earlier, Freon costs about $125 – $150 per pound. Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit.
Refrigerant is a working chemical that runs through your car's A/C system in either a gaseous or liquid form. Causes of refrigerant leaks in your vehicle include physical damage, wear and tear over time, and escaping refrigerant even without a leak.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.
Even after 2026, when the EPA will have banned hydrofluorocarbon production, you'd still get until at least that same year before purchasing the product would become illegal. That could extend until 2027. All said, beginning from 2024 onward, you could have three more years to purchase R-410A refrigerant.
The Environmental Protection Agency (EPA) began the phase out of Freon in 1992 when it ordered the ban that took effect in 2020. Because of the long phase-in starting in 2010, new air conditioning, heat pumps, and refrigeration systems stopped using Freon, which is also known as HCFC-22 and R-22.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Usually, it is a quick fix, but sometimes the failure can be caused by a much bigger problem. The most expensive part of an AC unit to replace and repair is the air compressor.
How much will a new AC unit save me? How much you can save with a new AC unit will depend on your old unit, the replacement model, how much you use your air conditioning, and the cost of electricity where you live. Estimates vary from 10% to 50% savings on your air conditioning costs per year.

A Question of Supply and Demand
Therefore, maintenance people and air conditioning system specialists have less supply and are charging more for it. Some businesses have even reported thefts targeting their Freon canisters thanks to its newfound value. After 2020, R-22 won't be produced at all in the United States.
Puron Advance is Carrier's new refrigerant that will replace Puron in all residential ducted, ductless, and light commercial products.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either. This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires.
Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
