Yes, specific drop-in replacement R-22 coils are manufactured by aftermarket specialists Sustainable Coils. However, Original Equipment Manufacturers (OEMs) largely stopped producing them directly, making it common for HVAC technicians to suggest system upgrades.
R22 phaseout in 2020 means that it's completely illegal to manufacture or import R22 into the country. Recovered, recycled, or reclaimed R22 can still service existing HVAC systems, but chemical manufacturers can't produce new R22 refrigerants to service existing air conditioners and heat pumps.
R-22 refrigerant typically costs between $𝟗𝟎 and $𝟐𝟓𝟎 per pound. Because R-22 has been phased out, the supply is dwindling, which causes prices to continuously climb.
Yes, you can install a 410A-rated evaporator coil on a R22 system, as modern aluminum coils are designed to handle the higher pressures of 410A and are compatible with R22 refrigerant. However, the metering device (piston or TXV) inside the coil must be matched to the R22 system requirements.
The best replacement for R-22 depends on your system's configuration. Because R-22 is fully phased out, the most common drop-in substitutes are R-438A (MO99), R-407C, and RS-44b (R-453A). These allow for system retrofits, though complete system replacement is often recommended for aging units.
The "best" R22 replacement depends on whether you are doing a drop-in retrofit (using existing equipment) or upgrading the whole system. For retrofits, the top choices are R407C for maximum efficiency and R422D for easier compatibility. For long-term viability, replacing the system entirely with an R454B or R32 system is recommended.
A2L refrigerants, the new refrigerants for 2026, will replace R-410A in new systems. A lot about A2L refrigerants is explained in their name: The “A” means low toxicity. The “2L” is a safety classification, indicating it is mildly flammable.
Never mix refrigerants, or "top off" a system running on R-22 with a 400-Series blend. Once the R-22 is removed and the new refrigerant is charged into the unit, the system can be topped off with the new refrigerant. Never liquid charge into the low side, though.
R-410A is currently being phased down rather than fully banned, with the production of new R-410A equipment already banned. The remaining supply will be gradually reduced by 85% through 2036.
Putting R-410A into an R-22 air conditioning system is a severe mistake that will cause the system to fail. Because R-410A operates at pressures roughly 50% to 60% higher than R-22, the system's compressor, coils, and refrigerant lines will be subjected to dangerous stress that can cause them to burst or blow seals.
A 30-pound cylinder of R-22 refrigerant is generally worth between $500 and $1,200 to purchase wholesale, and up to $2,400 to $4,500 if bought directly from a service company during a home repair.
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.

Yes, MO99 (also known as R-438A) is a direct, "no-oil-change" drop-in replacement for R-22. It is specifically engineered to replace R-22 in residential and commercial air conditioning, heat pumps, and refrigeration systems.
Yes, unless a R22 coil is found, it is not advisable to replace just the coil. I need a new evaporator coil that uses r22 HVAC system.
Short answer: Yes. Eligible R410A systems manufactured before January 1, 2025, can still be installed in 2026 under the Technology Transitions Rule issued by the U.S. Environmental Protection Agency. There is no nationwide ban on the installation of compliant R410A equipment.
Many Amish homes are built with plenty of windows to help circulate the air and bring in the cooler overnight temperatures. They open the windows on the top floors to help the heat escape while the family retreats to the lower grounds within their homes for comfort.
There is no single "best" AC brand, as the ideal choice depends on your region, budget, and whether you need whole-house central air or room units. Globally, industry leaders are ranked by their reliability, efficiency, and technological innovation.

Mixing R22 with R407C
According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined. Although you may this restriction is primarily political we would like to give you a basic education to explain the two most devastating effects of such action: To the environment.
Yes, R-438A (widely known as MO99) is a direct, non-ozone-depleting retrofit replacement for R-22 in residential and commercial air conditioning and refrigeration systems.
Meaning the phase out of R22 has been planned for almost 30 years. So in summary, it's true, the EPA has mandated that no new “virgin” “HCFC 22” can be manufactured or imported after 2020 due to its effect on the environment.
Yes, 2027 is widely expected by climate scientists to be hotter than 2026, with a high probability of breaking global temperature records.
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.
