Guardian Evcon GAW14L48C23S 4-Ton R407-C 14 Seer Air Conditioner

The Guardian Evcon GAW14L48C23S is a 4-ton central split-system air conditioner rated at 14 SEER, designed to retrofit existing R-22 systems where the legacy refrigerant is no longer commercially available. At 48,000 BTU, it is sized for single-family residential homes in the 2,400 to 3,200 square foot range or small commercial spaces with similar cooling loads — not the apartment-scale thru-wall applications most of our NYC inventory serves.

What makes this unit specifically useful is the R-407C refrigerant. R-407C is an HFC blend engineered as a direct retrofit path for R-22 systems — it is compatible with the POE synthetic lubricants used in modern equipment and can take over from R-22 in an existing line set and evaporator coil without redesigning the indoor side. If you have a legacy R-22 system that is reaching end of life, a Guardian Evcon R-407C unit is one of the cleanest swap paths available.

Specs: 48,000 BTU nominal cooling, 14 SEER efficiency, split-system configuration pairing with a matching air handler or evaporator coil, 208-230V single-phase power. The unit targets the single-family residential and small commercial retrofit market where R-22 replacement is the trigger for the equipment change rather than a full system redesign.

We price this unit aggressively because it fills a narrow but real niche: legacy R-22 retrofits where compatibility with existing R-22 line sets and evaporator coils matters more than the latest refrigerant specification. This is not a thru-wall unit and does not fit NYC apartment sleeve applications — it is central residential or light-commercial equipment.
