📍 Location: Frisco, TX | Single family house
🏠 Service: Condenser Replacement with Evaporator Coil – Addressing R-22 and R-410A Compatibility

A homeowner in Frisco contacted us after their 1999 R-22 condenser compressor failed. They requested a straightforward condenser replacement. Upon inspection, we discovered that the indoor air handler had been replaced in 2024 with a unit designed for R-410A refrigerant.
Mixing R-22 and R-410A refrigerants is a violation of EPA regulations and can lead to severe system issues, including corrosion of the compressor and clogging of the metering device. According to the EPA, refrigerants should never be mixed, and recovered refrigerants must be stored by type to prevent contamination.
Further discussion with the homeowner revealed that they had purchased the house the previous year. The home inspector had identified a refrigerant leak in the air handler, leading the seller to replace only the indoor unit, resulting in a mismatched system.

🛠 Our Solution:
To ensure compliance and system integrity, we recommend replacing the condenser along with the evaporator coil to match the R-410A refrigerant specifications. This approach prevents refrigerant contamination and aligns with industry best practices.

✅ The Result:
• Installed a compatible condenser and evaporator coil
• Ensured compliance with EPA regulations
• Enhanced system efficiency and longevity
• Provided the homeowner with peace of mind
• Saved the homeowner from potential future expenses associated with system failures due to refrigerant incompatibility
