When your heat pump stops working, you need a technician who diagnoses the real problem — not one who guesses. Same-day service across King, Pierce & Snohomish Counties.
Live Diagnostic
We diagnose the real problem.
Not just the symptom. Our technicians trace every fault to its root cause before recommending any repair.
What you notice at home is often just the surface. Here's what's usually happening underneath.
Not sure what's wrong? Book a diagnostic — we'll tell you exactly what's happening.
Recognize any of these? Our technicians have seen them all — and fixed them all.
Complete loss of output — usually a refrigerant leak, failed compressor, or electrical fault.
Heavy ice that won't clear signals low refrigerant or a failed defrost board.
Grinding, screeching, or banging — worn bearings, loose parts, or a failing compressor.
Constantly turning on and off — low refrigerant, restricted airflow, or oversized system.
System detected a fault and shut down. We decode all brands — Carrier, Trane, Lennox, Daikin, and more.
Runs constantly but can't keep up — dirty coil, low charge, or undersized for the home.
Gradual increase in energy use often points to a dirty coil or slightly low refrigerant.
Mold or bacteria on the evaporator coil. A professional coil cleaning resolves it.
"Heat pump stopped heating mid-January. Called at 7am, they were here by noon. Diagnosed a reversing valve issue, had the part on the truck, fixed same day. Unreal service."
"Our Mitsubishi was throwing error codes. Other company wanted to replace the whole unit. Next Phase found a faulty sensor and fixed it for a fraction of the cost."
"Ice was covering our outdoor unit for days. The tech found low refrigerant from a tiny leak, sealed it, recharged the system. Been running perfectly since."
"Upfront pricing before any work started. No surprises, no upselling. They explained exactly what was wrong and what it would cost. Refreshing experience."
"System was short cycling every few minutes. Turned out the filter was completely clogged and the coil was dirty. Quick fix, but the tech also showed me how to maintain it."

In most cases, same day. We serve King, Pierce, and Snohomish Counties and keep our trucks stocked with common parts. If you call in the morning, we can usually be there by afternoon.
Yes. We service Carrier, Trane, Lennox, Mitsubishi, Daikin, Goodman, Rheem, York, and every other major brand — regardless of age or who installed it.
We'll tell you honestly after the diagnostic. If the repair cost is reasonable relative to the system's remaining lifespan, we recommend repair. If not, we'll explain why replacement makes more sense — with no pressure either way.
Always. After diagnosing the issue, we provide exact pricing before any repair work begins. If you decline, you only pay the diagnostic fee. No surprises, no hidden charges.
All of our repairs are guaranteed. If the same issue returns within our warranty period, we come back and fix it at no additional cost. We also check whether your system is still under manufacturer warranty before any work begins.
Small heat pump problems become expensive ones. Book a diagnostic today and get the real answer — with upfront pricing before any work begins.
