R-22 Conversion

R-22 Refrigerant Conversion in NYC

R-22 (commonly known as Freon) was the standard refrigerant in HVAC systems for decades, but the EPA banned its production and import as of January 1, 2020 due to its ozone-depleting properties. If your AC system still uses R-22, Karl's Plumbing, Heating, and Cooling can convert it to an approved refrigerant so your system stays running legally and efficiently.

Is Your System Affected?

If your AC unit was manufactured before 2010, there is a strong chance it uses R-22 refrigerant. Signs that you may need a conversion include:

• Your system was installed before 2010 and has never been converted
• You've been told R-22 is no longer available or is prohibitively expensive
• Your system has a refrigerant leak and recharging with R-22 is impractical
• You want to comply with EPA regulations and reduce your environmental impact

The Conversion Process

Our EPA-certified technicians follow a careful multi-step process to convert your system from R-22 to R-410A or another approved alternative:

1. System evaluation — We inspect your unit to determine if conversion is feasible or if full replacement makes more sense
2. Refrigerant evacuation — All R-22 is safely recovered from the system following EPA disposal guidelines
3. System flush — The entire system is flushed to remove all traces of R-22 and mineral oil
4. Component replacement — The compressor, accumulator, expansion valve, and other components are replaced with R-410A-compatible parts
5. Recharge and test — The system is recharged with R-410A and thoroughly tested for leaks and proper operation

Conversion vs. Full Replacement

In some cases, converting an older system may not be the most cost-effective option. If your unit is over 15 years old, a full system replacement with a modern high-efficiency unit may save more money in the long run through lower energy bills and reduced repair costs. Our technicians will provide an honest assessment and help you make the best decision for your property.
