A homeowner called us for an urgent AC repair in Rosman, NC, because their central air conditioner was not cooling on a warm September afternoon. Upon arrival, I performed a full diagnostic service and found the system was critically low on refrigerant. To provide a lasting solution, I conducted an electronic leak detection, a vital step for any proper emergency AC repair. I located and sealed a small leak at a service valve before evacuating the system and recharging it to the exact factory specification. The customer was grateful for the thorough repair and pleased to have their AC working correctly, mentioning they'd recommend our Transylvania County HVAC services to their neighbors.
