How much does residential heat pump repair cost?

Our residential diagnostic visit is $169. Additional repair costs depend on the diagnosis and the components involved. After diagnosing the issue, we explain the findings and provide pricing for any recommended repairs before you authorize additional work.

Why is my heat pump running but not heating?

A heat pump that runs without heating can be caused by thermostat settings, airflow restrictions such as a dirty filter, the system being in defrost mode, or a mechanical or refrigerant-related issue. Because these can look similar from the outside, we recommend a professional diagnosis if the problem persists.

Is frost on my heat pump normal?

Yes — some frost and periodic defrost cycles are normal, especially in cool, damp Washington weather. Heavy or persistent ice buildup that doesn't clear, however, may indicate a problem worth inspecting.

Do you offer emergency heat pump repair?

Our main office handles regular service during business hours at (425) 579-9564. For after-hours emergencies, call our dedicated line at (425) 533-3831. Emergency appointments depend on technician availability.

How quickly can you repair my heat pump?

Scheduling and repair completion depend on your location, the equipment involved, technician availability, the diagnosed problem, and any required parts. We prioritize urgent requests and let you know what to expect.

Should I repair or replace my heat pump?

It depends on the overall condition of the equipment, its age, the cost of the current repair, how reliable it has been, and its long-term operating efficiency. We'll walk you through these factors rather than relying on rigid thresholds.

Can a heat pump work during freezing temperatures?

Modern heat pumps can provide heating in cold weather, but output and efficiency vary by system design, outdoor conditions, and equipment condition. If your system seems to struggle in the cold, a professional inspection can help determine whether it's operating as designed.

Is Your Heat Pump Having Trouble Keeping Up?

Heat pumps provide both heating and cooling, so a malfunction can affect your comfort throughout the year. Whether your system isn't producing enough heat, won't switch modes, or is making unusual noises, Miller Mechanical can help identify the problem.

Heat Pump Not Heating

Your heat pump is running, but your home isn't reaching the temperature you've set.

Heat Pump Blowing Cool Air

Air feels cooler than expected, or the system struggles to maintain comfort. Some cooler airflow during normal operation or defrost cycles doesn't necessarily indicate a malfunction.

Frozen or Iced-Over Outdoor Unit

Light frost is normal, but heavy or persistent ice buildup may indicate an airflow, defrost, or system performance issue.

Heat Pump Won't Switch Modes

Your equipment struggles to transition between heating and cooling.

Unusual Noises

Grinding, rattling, buzzing, or other unexpected sounds may indicate mechanical or electrical problems.

Heat Pump Running Constantly

The system runs continuously without maintaining the desired temperature. Some extended operation is normal during demanding weather.

Rising Energy Bills or Poor Efficiency

Changes in energy consumption or system performance may indicate an issue requiring professional inspection.

Repair or Replace

Is It Better to Repair or Replace Your Heat Pump?

Not every heat pump problem requires replacing the entire system. Sometimes a targeted repair is the most practical solution. In other situations, the system's condition, age, efficiency, and repair history may make replacement worth considering.

Repair

Repair May Be the Better Choice When:

The equipment is otherwise operating reliably.
The issue is isolated and repairable.
The system has not experienced frequent breakdowns.
The repair cost is reasonable relative to replacement.
Existing equipment performance meets the homeowner's needs.

Replace

Replacement May Be Worth Considering When:

The equipment is approaching the end of its useful service life.
Major components require expensive repairs.
Breakdowns are becoming increasingly frequent.
Comfort and efficiency problems are persistent.
The homeowner wants to evaluate long-term operating costs.

We'll help you understand the available options so you can make the right decision for your home and budget.
