When a condensing unit reaches the end of its life, replacement is usually better value than a third major repair. JRC replaces commercial condensing units across Dallas, TX for walk ins, display cases and multi box systems.
Sizing is where these jobs go wrong. A unit picked to match the old nameplate can be wrong if the box use has changed, if the insulation has degraded, or if the original was oversized to begin with. We calculate the actual load. Refrigerant type matters too, since older units on phased down refrigerants often make replacement the sensible move on running cost alone. Line sets get pressure tested and evacuated properly rather than reused on trust.
