AC Replacement in Coto de Caza: From R-22 to R-454B

On November 9, 2026, the GoTech Air Conditioning & Heating team completed an AC replacement in Coto de Caza. The old outdoor unit was badly rusted and leaking refrigerant (Freon), and its base had corroded through in places. We removed it and installed a new outdoor condenser in its place.

The old unit and the new one

The removed outdoor unit was model 38CKC060300, which used R-22 refrigerant. The new outdoor condenser uses R-454B refrigerant.

Before and after

Before removal, the old unit showed heavy rust, with holes corroded through its base. The new condenser now sits on its pad with the disconnect and insulated refrigerant lines in place, and after the install its outdoor fan was running.
