We typically recommend considering replacement if your system is over 10-15 years old, requires frequent repairs, or if your energy bills are steadily increasing.

Yes, issues with heat pump performance, especially related to the reversing valve or refrigerant levels, are common in our area due to the system's year-round use for both heating and cooling. A faulty reversing valve can prevent the system from switching modes. Our technicians are experienced in diagnosing and repairing these specific components to restore your system's efficient operation, often saving you from a more costly full system failure.
