When temperatures drop below freezing, heat pumps work harder to extract heat from outdoor air. Common causes of poor heating include: a failing reversing valve stuck in cooling mode, low refrigerant levels, a faulty defrost control board, or ice buildup on the outdoor unit. If your heat pump is struggling during a Washington cold snap, call us for a professional diagnosis before the problem worsens.
Some frost is normal—heat pumps have a defrost cycle that kicks in periodically. But if ice covers the entire unit and won't melt, you may have a failed defrost control board, low refrigerant, a broken defrost sensor, or a malfunctioning reversing valve. Don't chip the ice off manually—you could damage the coils. Call us instead for a proper repair.
Heat pump repair costs vary by issue. Our diagnostic fee starts at $169, and we provide a transparent quote before any work begins. Minor repairs like a capacitor or contactor replacement may cost a few hundred dollars. Major repairs—like a compressor or reversing valve—cost more. We always discuss your options so you can make an informed decision.
Heat pumps do run longer than furnaces—that's normal, especially in very cold weather. But if it's running nonstop, possible causes include: a thermostat that's not calibrated correctly, a dirty air filter restricting airflow, low refrigerant charge reducing efficiency, undersized equipment for your home, or leaking ductwork wasting conditioned air. We can diagnose and fix the root cause.
Here's our honest guideline: if your heat pump is under 10 years old and the repair is minor, repair it. If it's 10-15 years old and needs a compressor or major repair, replacement often makes more financial sense. Heat pumps over 15 years old are usually better replaced, as newer models are dramatically more efficient. We provide free assessments to help you decide—no pressure, just honest advice.
Our comprehensive heat pump maintenance includes: checking refrigerant levels and testing for leaks, inspecting and cleaning both indoor and outdoor coils, testing the reversing valve and defrost cycle, checking electrical connections and capacitors, inspecting the compressor, cleaning or replacing air filters, testing thermostat operation, and measuring overall system performance. Annual maintenance helps prevent 80% of common breakdowns.
A well-maintained heat pump in Western Washington typically lasts 12-15 years. Our mild climate is actually gentler on heat pumps compared to regions with extreme cold or heat. Annual professional maintenance is the #1 factor in extending your heat pump's lifespan. We've serviced units that are 18+ years old and still running efficiently thanks to regular care.
