From initial contact to final verification — here is how we handle heat pump repair.
KIC Refrigeration begins every heat pump repair in Hillsdale, MI with a dual-mode performance test. We measure supply air temperatures in heat and cool, verify the reversing valve energizes and de-energizes properly, and test the defrost control board to confirm it initiates defrost cycles at the correct intervals.
At your Hillsdale property, our technician connects digital manifold gauges and measures suction pressure, discharge pressure, liquid line temperature, and suction line temperature. We calculate superheat and subcooling to determine if the charge is correct or if there is a restriction in the metering device or a refrigerant leak.
We replace the failed component — compressor, reversing valve, defrost board, contactor, capacitor, or metering device — using OEM or equivalent parts rated for your system tonnage and refrigerant type.
KIC Refrigeration does not consider your Hillsdale, MI heat pump repair complete until every performance metric checks out. We verify pressures, temperatures, amperage draws, defrost timing, reversing valve switching, and thermostat communication before signing off on the work.
Transparent answers about heat pump repair from our certified technicians.
Heat pump repair in Hillsdale typically ranges from $150 to $600 for common component failures like run capacitors, contactors, defrost timers, and condenser fan motors. Reversing valve replacement is a more involved job that runs $800 to $2,000 including refrigerant recovery and recharge. Compressor replacement costs $1,500 to $3,000 depending on the unit tonnage, refrigerant type — whether R-410A or older R-22 — and whether a hard-start kit is needed. KIC Refrigeration provides a detailed written estimate with parts and labor itemized before any work begins at your Hillsdale property, so you know exactly what the repair will cost.
Heat pump icing is caused by conditions that prevent the defrost cycle from working correctly. The most common culprits are low refrigerant charge from a slow leak, a dirty or blocked outdoor coil that restricts airflow, a failed defrost control board or timer that does not initiate the defrost sequence, a stuck defrost relay, or a malfunctioning outdoor fan motor. In normal operation, the defrost cycle activates every 30 to 90 minutes during cold weather, reversing the system briefly to melt accumulated frost. When any component in this chain fails, ice builds up until the unit shuts down on high-pressure safety. KIC Refrigeration tests the complete defrost circuit and refrigerant charge at your Hillsdale, MI home to identify and fix the root cause.
Most heat pump repairs in Hillsdale are completed in 1 to 3 hours during a single service visit. Common electrical component failures — capacitors, contactors, defrost relays, and flame sensors — typically take 30 to 60 minutes. Fan motor replacements take 1 to 2 hours. Reversing valve and compressor replacements are the most time-intensive repairs at 4 to 6 hours because they require refrigerant recovery with a certified machine, component removal, brazing with nitrogen purge, leak testing, evacuation to below 500 microns, and recharging by weight. KIC Refrigeration arrives at your Hillsdale home with a fully stocked truck to minimize return trips and keep your downtime as short as possible.
A heat pump blowing cold air in heating mode is most commonly caused by a failed reversing valve solenoid, which gets stuck and prevents the system from switching from cooling to heating. Other causes include low refrigerant charge that reduces the heat output at the condenser coil, a stuck or failed defrost control board that keeps the outdoor unit in defrost mode too long, or a thermostat that has lost communication with the control board. KIC Refrigeration tests the reversing valve by measuring the temperature difference across it, checks refrigerant pressures with manifold gauges, and verifies the defrost sequence to isolate the exact cause at your Hillsdale property.
Our reputation is built on certified technicians, honest pricing, and results that last.
