Heat Pump Repair Services

• Auxiliary Heat (Emergency Heat) Runs Constantly: If your expensive electric heat strips are always on, your heat pump isn't doing its primary job, leading to massive electric bills.
• Outdoor Unit Fan Not Spinning: Prevents heat exchange with the outside air. Could be a bad fan motor, capacitor, or obstruction.

When in COOLING Mode (or year-round issues):

• Reduced Cooling Power or No Cold Air: Similar to AC failure, pointing to refrigerant issues, dirty coils, or compressor problems.
• Outdoor Unit Vibrates Excessively or is Noisy: Could indicate a failing compressor, loose parts, or debris in the fan.
• System Short-Cycling: Turns on and off every few minutes. Often caused by a dirty filter, faulty thermostat, or incorrect refrigerant charge.
• Higher Than Normal Energy Bills: Inefficient operation in either mode will show up as a steady, unexplained increase in your electricity costs.

Our Specialized Heat Pump Repair Services

• Defrost Cycle Diagnosis & Repair: Replacing faulty defrost control boards, sensors, and timers to prevent winter ice-over.
• Reversing Valve Service: Testing, troubleshooting, and replacing this critical valve that switches the system between heating and cooling modes.
• Refrigerant Leak Detection & Repair: Finding leaks in the complex refrigerant circuit, repairing them, and performing a precise recharge to manufacturer specifications.
• Compressor & Start Component Testing: Diagnosing hard-starting or failed compressors and replacing associated capacitors and contactors.
• Dual Thermostat & Control Wiring Diagnostics: Ensuring your thermostat is correctly configured for a heat pump system and that all stage signals are communicating properly.
• Auxiliary Heat Strip Repair: Fixing issues with the backup electric heating elements that engage during extreme cold.
• Year-Round Maintenance & Performance Tuning: Cleaning both indoor and outdoor coils, checking airflow, and verifying system pressures in both heating and cooling modes.

Why Heat Pump Repairs Are More Complex

Your heat pump is essentially an air conditioner that can run in reverse. This adds layers of complexity:

• The Reversing Valve: A specialized component not found in standard ACs that is prone to electrical failure or mechanical sticking.
• The Defrost System: A necessary system to melt winter ice, involving its own set of controls and sensors that can fail.
• Two-Coil Operation: Both the indoor and outdoor coils act as the evaporator or condenser depending on the mode, meaning both are critical for all-season performance.
• Dual-Fuel or Hybrid Systems: If paired with a gas furnace, the integration and control between the two systems requires expert calibration.

The 551 HVAC Heat Pump Repair Difference

• We Test in Both Modes: A proper diagnosis involves checking operation in heating and cooling, even if you only have a complaint in one season.
• We Understand the Full Sequence: From the thermostat's "O/B" signal to the reversing valve shift and the defrost cycle timing, we trace the entire process.
• We Focus on Efficiency: Incorrect refrigerant charge or airflow cripples a heat pump's efficiency more severely than a standard system. We restore it to peak performance.
• Honest Repair/Replace Guidance: We’ll tell you if repairing an older, low-efficiency (8-10 HSPF/SEER) heat pump is worth it, or if upgrading to a modern, high-efficiency model will save you more in the long run.

We make sure our customers understand every step of the process, so we can work together to deliver exactly what they need. Still haven’t decided if a heat pump is great for you?
