Yes, R-22 (Freon) is still available for servicing older HVAC and refrigeration units, but it can no longer be manufactured or imported in the U.S. Today, technicians rely entirely on recycled, reclaimed, and existing stockpiled supplies, which makes it very expensive.
A pound of R-22 refrigerant typically costs between $90 and $250 per pound installed, with an average of around $150 per pound. Total costs vary based on your location and the amount your specific system needs.
No, the general public cannot buy R-22 refrigerant. Under Environmental Protection Agency (EPA) regulations, you must be a licensed, EPA-certified HVAC professional to legally purchase and handle R-22.
Yes, it is entirely legal to use an existing air conditioning or refrigeration system that runs on R-22. However, under EPA regulations, producing or importing new R-22 is illegal. Only reclaimed, recycled, or existing stockpiles can be used for repairs, which makes it very expensive.
A 30 lb cylinder of R-22 refrigerant is typically worth between $500 and $800 at wholesale. However, if you are buying it from an HVAC supply house or having a technician recharge your system, the retail cost to get and install it can range from $2,700 to $4,500 ($90 to $150+ per pound).
If you're interested in learning how to refill R22 in your air conditioner, it is important to know that this is not something a homeowner can do on their own. Due to complexity, safety concerns, training and licensing required we do not recommend doing this without having a trained professional onsite.

The HVAC industry is fully transitioning to next-generation A2L refrigerants, primarily R-454B and R-32. Driven by federal environmental mandates, these replacements drastically reduce the carbon footprint compared to older HFC types.
The best, most practical drop-in substitutes for R-22 are R-407C, R-421A, and R-438A (Freon MO99). These are zero-ozone-depleting blends that closely match the pressures and capacities of R-22 without requiring a full system replacement.
R-22 is extremely expensive because it has been legally phased out. Driven by federal environmental regulations, skyrocketing supply chain costs, and contractor labor rates, prices range from $100 to $300+ per pound, meaning a standard refill can cost between $800 and $2,000+.
Mixing refrigerants is always a no-no. Drop-ins aren't so great either. R-22 air conditioning systems are headed to the dustbin of HVAC history. If your old AC has a refrigerant leak and your warranty has expired, the best thing to do is invest in a new system and a professional installation.
Adding refrigerant to your central A/C system isn't something you should need to do regularly. In fact, a properly functioning system is designed to run efficiently without requiring frequent refills. On average, most central air conditioning systems need to have the refrigerant replaced ever two to five years.
If you are asking about a brand new R-22 air conditioning unit, they are no longer manufactured, as the production and importation of new R-22 and R-22 systems have been illegal in the U.S. since 2020. However, if you are looking to buy brand new (virgin) R-22 refrigerant to service an existing system, it costs between $90 and $250 per pound.
Comstar RS-44b is the closest, market available drop-in replacement for R22 that requires no oil changes and no system changes.
Yes, MO99 (R-438A) is widely considered a good and highly convenient replacement for R-22. However, weighing its pros and cons is essential:
Amish households stay cool without air conditioning by utilizing natural ventilation, passive cooling design, and strategic daily habits. Key methods include maximizing cross-ventilation with open windows, utilizing shade from trees and porches, and using basements or lower levels during peak heat. They also use battery-operated fans and rely on high ceilings to allow hot air to rise, keeping living spaces comfortable.
You cannot directly drop R-410A into an existing R-22 system because R-410A operates at much higher pressures. Using it in unmodified R-22 components can cause severe leaks, ruptured lines, and compressor failure.
Legally, no, you cannot refill an R-22 system yourself. Under EPA regulations, purchasing and handling restricted refrigerants like R-22 requires an EPA Section 608 Certification. Attempting to do so without a license can result in severe federal fines.
A 30 lb cylinder of R-22 refrigerant is typically worth between $500 and $800 at wholesale. However, if you are buying it from an HVAC supply house or having a technician recharge your system, the retail cost to get and install it can range from $2,700 to $4,500 ($90 to $150+ per pound).
The $5,000 rule is a quick formula used to decide whether to repair or replace an aging HVAC system. It helps homeowners avoid the trap of continuously pouring money into old equipment that is nearing the end of its lifespan.
Whether you flip an R22 tank upside down depends entirely on what you are trying to do with the system. Because R22 is a single-component refrigerant (not a blended mix like R410A), it can safely be dispensed as either a liquid or a vapor.
Replacing R-22 requires an EPA-certified HVAC technician to either perform a "drop-in" retrofit using specific transitional blends or replace the system entirely. Popular R-22 substitutes include R-438A (Freon MO99), R-422B, and R-407C.
Which AC brand lasts the longest in 2026? Historically, Lennox, Trane, and American Standard lead the industry in longevity. With proper maintenance, these units can last 15–20 years.
