Refrigerant does not deplete on its own under normal operation — so if your system has needed a top-up more than once, there is a leak that keeps coming back. Recurring refrigerant leaks in an aging AC system are a strong signal that the integrity of the refrigerant lines is compromised, and continued top-ups without resolving the source adds ongoing cost without fixing the underlying problem. Sherwood Mechanical Services assesses refrigerant issues for homeowners across Sherwood Park and surrounding communities.
