Joshua replaced my AC mini-split and did an excellent job. He was professional, knowledgeable, and took the time to explain everything clearly. The installation was done quickly and with great attention to detail, and the system has been running perfectly ever since. I really appreciate the honest service and would highly recommend Joshua and his team to anyone needing HVAC work.

Overview

Heat Pump Repair done right

Westside Comfort Solutions is a licensed HVAC contractor serving Renton, WA that repairs heat pumps for both their heating and cooling modes.

A heat pump does the work of a furnace and an AC, so an accurate diagnosis matters. We read the system and fix the real fault instead of swapping parts.

  • No-heat and no-cool diagnostics
  • Reversing valve and defrost faults
  • Refrigerant leak detection and recharge
  • Compressor and control repair
  • Auxiliary and backup heat troubleshooting

Why it matters

Why heat pump repair is worth doing right

A heat pump does the work of both a furnace and an air conditioner, moving heat in or out depending on the season, so an accurate diagnosis matters more than with single-mode equipment. A stuck reversing valve, a defrost-control fault, low refrigerant, or a failed compressor can each leave you with cold air in winter or warm air in summer, and the fix is different for each.

Heat pumps are common across Western Washington because our mild, electric-friendly climate suits them well. We service the central and ductless systems that homes here rely on year-round, and we read the system properly rather than throwing parts at the symptom.

Warning signs

Signs your heat pump needs repair

Heat pumps signal trouble in both their heating and cooling modes. Watch for:

  • Cold air when it's calling for heat, or warm air when it's calling for cool
  • The outdoor unit iced over and not defrosting
  • Short cycling, or running constantly without reaching setpoint
  • The system stuck running on expensive backup or auxiliary heat
  • Grinding, buzzing, or hissing at the outdoor unit
  • A spike in your electric bill with no change in use
  • The reversing valve not switching between heat and cool

How it works

What to expect with heat pump repair

  1. 01

    Diagnostic visit

    We read the system, refrigerant charge, reversing valve, defrost control, compressor, and backup heat, to find the actual fault in whichever mode is failing.

  2. 02

    Find the root cause

    We pinpoint why it failed so the repair holds, rather than swapping a part and hoping.

  3. 03

    Quote before work

    You get a clear price up front and an honest read on repair versus replacement if the system is aging.

  4. 04

    Repair and test

    We repair with correct parts and test both heating and cooling modes, including a defrost cycle, before we leave.

Fair, upfront pricing

What affects the cost

We quote after we diagnose the system. What affects the price:

  • The failed component (a defrost sensor is minor; a reversing valve or compressor is major)
  • Whether the system is low on refrigerant, and which type
  • Central versus ductless system
  • Accessibility of the indoor and outdoor units
  • The age and condition of the overall system

Every job is different, so you get a clear quote before any work starts, with no surprises. Financing is available, so the right fix doesn't have to wait. We're licensed (WESTSCS752MT) and insured, and we back our work with a 1-year workmanship guarantee.

We treat every heat pump repair job like it's in our own home: diagnose it right, quote it fair, and stand behind the work.

Questions

Common questions about heat pump repair

Why is my heat pump blowing cold air in winter?

It can be a stuck reversing valve, a defrost fault, low refrigerant, or a failed control. We diagnose which one rather than guessing, because the fix is different for each.

Can you service any heat pump brand?

Yes. We service the common brands and are a Mitsubishi Diamond dealer for ductless and central heat pump systems.

Why is my heat pump running on backup heat all the time?

Constant auxiliary or emergency heat usually means the heat pump isn't keeping up, often from low refrigerant, a defrost fault, or a sensor problem. It also spikes your electric bill, so it's worth diagnosing rather than living with.

Why is my outdoor unit covered in ice?

A little frost is normal in winter, but a unit iced solid means the defrost cycle isn't working, from a failed sensor, control board, or low charge. Running it that way strains the system, so we find the cause.

Is it worth repairing an older heat pump?

Often, yes, but if the compressor or reversing valve fails on a system near the end of its life, we'll give you the honest repair-versus-replace math instead of pushing either way.
