Yes, heat pump reversing valve issues are a frequent service call we handle, especially with our variable climate. When the valve fails, the system can't change modes, leaving you without heat or cool air when you need it. As a Master HVAC technician, I can diagnose if the valve itself is stuck or if it's an electrical control issue. Often, timely maintenance can identify early wear, but we're equipped to perform efficient repairs or replacements to restore your home's comfort.
