If you put the newer freon in right away, your unit will rupture due to the force. However, you can convert your AC unit to handle R410A. You'll need to replace the compressor, condenser, evaporator, and likely the refrigerant tubing. If you replace all of this, your old unit will work fine with the new freon.
Impact on Current HVAC Systems
If your current HVAC system uses older refrigerants like R-410A or R-22, it will not be compatible with the new refrigerants. However, existing systems can continue to be serviced and maintained with R-410A replacement units for the foreseeable future.
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.
If you need refrigerant for your air conditioner, you'll need to contact a professional heating and cooling technician. Under EPA regulations, only a certified professional can recharge your home's HVAC system. You should never try to recharge the A/C yourself, even if you have a home air conditioner recharging kit.
How Much Does a Freon Refill Cost? Typically, a Freon refill costs anywhere from $100-$350. The amount varies due to several factors, including the size and type of your air conditioning system. The coolant will cost around $75-$175.
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.
Understanding the Current HVAC Refrigerant Guidelines
Most HVAC brands have started to swap out their older AC and heat pump units over the year, preparing for the 2025 deadline, when they will have to completely stop the production of systems with R-410A.
R-410 refrigerant costs $60 per pound on average, but can range from $40 to $75. Keep in mind you cannot purchase R-410A refrigerant without an HVAC pro. As of mid-2024, R-410A refrigerant prices range from $40 to $75 per pound.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
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.
Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit. If you own a larger r22 unit, you may have to spend $600 or more. To break this down for you, a 25lbs unit of r410A costs anything between $100 and $175.
Only a technician licensed by the U.S. Environmental Protection Agency (EPA) can legally handle R-22 or Freon. So if your air conditioner uses the refrigerant R-22, you'll be breaking the law by handling the chemical on your own.
R22 (also known as HCFC-22) is a chlorofluorocarbon (CFC) once widely used as a refrigerant. If your home or office AC is over 10 years old, it's probably using R22 freon. However, R22 Freon is banned in the U.S. today. If your AC system uses R22 refrigerant, you might be worried about how this may affect you.
In 2010, the U.S. stopped the sale of newly manufactured residential air conditioning units and heat pumps that use R-22 because of its particularly harmful impact on the ozone layer when released into the air. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22.
R-22 refrigerant prices range from $90 to $250 per pound. Since you'll need between 6 and 12 pounds to refill a home AC, costs can reach between $660 and $2,400 for a refill of R-22 refrigerant. U.S.
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.
According to PG&E, most central air conditioning systems use two to four pounds of refrigerant per ton of cooling capacity. A three-ton air conditioner would typically have six to 12 pounds of refrigerant for a proper charge.
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.
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.
There are a number of reasons why your air conditioner might be running but not cooling. It could be an issue with the thermostat, the compressor, or the evaporator coils. Or, it could simply be clogged with dust and debris, which is preventing it from working properly.
Here's a question we hear often from those who brave the humid Atlanta weather: “Should I run my air conditioner with a ceiling fan?” Answer: You can— and should— run your A/C and ceiling fan together. Doing so can help lower your cooling costs each month, but only if you're using them right.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
