The vacuum and refrigerant charge phase is the most critical step in any AC installation. If oxygen or moisture remains in the copper lines, it reacts with refrigerant oil to form acid — silently corroding the compressor from the inside. Most compressor failures within 1–3 years of installation trace back to this one skipped step. At 4Most Energy, we never cut corners on the vacuum pull or refrigerant charge — your compressor depends on it.
