Which Heat Pump Problem Matches Your Home?
The heat pump is not heating
If the room temperature keeps falling or the system cannot reach the thermostat setting, tell AVS how the indoor and outdoor units behave. Controls, airflow and equipment faults can affect heating performance.
The heat pump is not cooling
Warm air in cooling mode can involve airflow, electrical components, refrigerant-circuit performance or mode-control problems. Let us know whether heating still works and whether cooling failed suddenly or gradually.
Auxiliary heat is always on
Auxiliary heat can support normal heating under some operating conditions. If it runs persistently, particularly when the system previously maintained comfort without it, ask for an evaluation. The diagnosis may need to distinguish thermostat settings and heating demand from an equipment fault.
Ice stays on the outdoor unit
Light frost and a defrost cycle can occur during heat-pump heating. Heavy ice that does not clear, ice interfering with the fan or declining indoor comfort needs attention. Do not chip ice off the coil or force the fan to move.
The heat pump keeps cycling or seems to run continuously
Frequent starting and stopping can indicate a problem. Longer running periods need context: equipment design, outdoor conditions and heating demand affect runtime. Tell AVS whether the house reaches the set temperature and what has changed.
The outdoor fan stops, the unit gets noisy or energy use changes
Describe when it happens and whether the sound or fan behavior is new. A fan pause alone does not establish the cause. For a rise in energy use, bring recent bills and note changes in weather, thermostat settings and occupancy as well as equipment behavior.
Normal Defrost or a Frozen Heat Pump?
During heating, a heat pump may periodically clear frost from its outdoor coil. A brief change in operation followed by a return to normal heating can be part of that process. Trane explains the heat-pump defrost cycle.
The more useful question is what happens afterward. Does the ice clear? Does normal heating resume? Does the home stay comfortable? Persistent ice, repeated disruption or poor heating warrants diagnosis of the equipment and its defrost operation.
If you see smoke, smell burning or suspect an electrical hazard, stop using the system and seek appropriate help. Do not assume every unusual condition is a normal defrost cycle.
What a Heat Pump Diagnosis May Cover
A heat pump that fails in one mode may need a different repair from one that fails in both. Depending on the symptoms and equipment, the inspection may involve:
- Thermostat setup, mode commands and backup-heat controls.
- Indoor airflow, filters, coils and blower operation.
- Power supply, electrical connections, capacitors and fan components.
- Defrost controls and sensors.
- Refrigerant-circuit performance and possible leaks.
- Reversing-valve operation and compressor condition.
The reversing valve changes refrigerant flow so the system can switch between heating and cooling. A mode-change problem calls for diagnosis of both the valve and its controls before a repair decision. Carrier’s reversing-valve explanation.
What Affects Heat Pump Repair Cost?
Heat pump repair cost in Northern Virginia and Maryland depends on the diagnosed fault and system design. A thermostat issue or outdoor fan repair differs from a defrost-board replacement, refrigerant leak repair, reversing-valve repair or compressor replacement.
Equipment access, parts availability, the extent of a leak and applicable warranty coverage can change the estimate. Variable-speed and communicating systems may also require equipment-specific components and diagnostic procedures.
Ask whether the quoted repair addresses the complete fault, what testing is included and whether further work may be needed. A clear scope is more useful than comparing the price of a part alone.

Repair or Replace the Heat Pump?
A repair can be a reasonable choice when the fault is isolated and the rest of the system remains serviceable. Replacement deserves comparison when major repairs recur, important components are difficult to source or the equipment continues to struggle in heating or cooling mode.
Consider both seasons. A repair decision should account for the system’s heating performance, cooling performance, condition and history—not just the problem that prompted today’s call. Also consider airflow or control problems that may need correction whichever option you choose.
If replacement is appropriate to explore, see heat pump installation and replacement.
Tell AVS What Type of Heat Pump You Have
When booking, identify whether your system is ducted or ductless, uses inverter or variable-speed equipment, or works with a furnace as a dual-fuel system. If you are unsure, provide the brand and accessible model information.
The team can confirm support for your particular equipment before arranging service. Avoid opening the unit to identify internal components.
