Many homeowners repair one faulty part, only to find another fault shortly after — a continuous, costly cycle. If your unit is aged, the indoor and outdoor units have been running the same number of hours and wear at the same rate. Fixing just one part while the other is near end-of-life rarely makes economic sense. City Cooling will always advise you honestly on whether a repair, parts replacement, or full unit replacement is the most cost-effective choice for your situation.
