A homeowner in Allen, TX reached out after noticing their air conditioner was running constantly but failing to cool the home. They had already taken some good steps on their own — cleaning the outdoor unit and replacing the air filters — but the system still wasn't performing. Our technician arrived to take a closer look and quickly identified the root cause: a leaking evaporator coil. The leak had caused the system to lose refrigerant over time, which is a common reason a properly sized unit stops cooling effectively. We added 5 pounds of R-410A refrigerant to restore the system to its correct charge. With a 5-ton system, maintaining the right refrigerant level is essential for efficient operation. Homeowners should know that if a coil is leaking, recharging the refrigerant is a temporary fix. We recommend addressing the leak directly to prevent the issue from returning and to protect the long-term health of the system.
