Heat Pump Failures
That AC Repair Pages Don't Cover
Heat pumps share most components with central AC units — but they have additional systems unique to year-round heating and cooling. These are the failures that heat pump owners experience that AC-only technicians aren't always trained to diagnose.
Heat pumps accumulate frost on the outdoor coil in cold weather — a normal defrost cycle melts it automatically. When the defrost system fails, heavy ice builds up until the compressor is blocked. Turn the system off immediately if the outdoor unit is heavily iced. Causes: failed defrost control board, defrost thermostat/sensor, or reversing valve failure.
The reversing valve switches refrigerant flow direction between heating and cooling mode. Signs it has failed: heat pump blows warm air in cooling mode, or cool air in heating mode. System may be locked in one mode. Reversing valve replacement is a same-day repair on most residential units — Hawana stocks common valves.
Most modern heat pumps display error codes on the indoor unit or thermostat. Common codes — E1 (communication fault), E3/E4 (pressure fault), E6 (outdoor unit fault), H6 (compressor protection) — indicate specific failure modes. Note your error code before calling — it significantly speeds up diagnosis and parts preparation.
The most common single repair on heat pumps — same as AC. The run capacitor fails under sustained load. Signs: outdoor unit hums but doesn't start. Multiple sizes stocked on every truck. 30-minute repair. If this is the cause, the heat pump is running again within an hour of arrival.
Low refrigerant in a heat pump causes reduced heating AND cooling efficiency. Since heat pumps work year-round, leaks often present as "poor heating in winter" rather than the obvious summer AC failure. Hawana locates the leak, repairs it, and recharges to spec. Both R-410A and R-32 A2L systems serviced.
A failed compressor is the most expensive heat pump repair. Hawana's honest assessment: if the unit is under 10 years old and the compressor has failed under warranty conditions, repair may be warranted. For older units, same-day new heat pump installation from $7,500 is typically the better economic choice. Written quotes for both, no pressure either way.
Common Heat Pump Error Codes
London Ontario — What They Mean
Note your error code before calling Hawana — it allows the technician to prepare the likely part and diagnose faster. Error codes vary by brand but most follow common patterns.
Indoor and outdoor unit not communicating. Usually wiring, a blown fuse on the control board, or a faulty control board. Check that power is on to both units first.
System pressure too high. Causes: dirty condenser coil, blocked airflow, refrigerant overcharge, or faulty high-pressure switch. Turn system off and call Hawana.
Refrigerant pressure too low — typically a leak. Running the system low on refrigerant damages the compressor. Turn off and call Hawana for leak detection and recharge.
Broad outdoor unit fault. Can indicate communication issue, protection mode, or component failure. Requires diagnostic. Note any other symptoms alongside this code.
Compressor thermal protection activated — system overheated or experienced abnormal pressure. Turn system off for 30 minutes, then try restart. If code returns, call Hawana.
Indoor or outdoor temperature sensor fault. System may run incorrectly or not start. Sensor replacement is typically a quick same-day repair — sensors are commonly in stock.
Error codes vary by brand. Lennox, Carrier, Mitsubishi, Daikin, Goodman, Kepler, and others use different code systems. When calling Hawana, tell the technician: your brand, model if visible, the error code, and what the system is doing. This combination allows faster diagnosis and part preparation before arrival.
