From initial contact to final verification — here is how we handle heat pump repair.
We test your heat pump in both heating and cooling modes, checking the reversing valve operation, defrost cycle initiation, and auxiliary heat engagement to isolate which mode and component is failing.
KIC Refrigeration performs a complete refrigerant circuit analysis on your North Fond du Lac, WI heat pump. We measure high-side and low-side pressures against the manufacturer target chart for current outdoor ambient temperature, calculate subcooling at the condenser and superheat at the evaporator, and use electronic leak detectors to locate any refrigerant loss.
Our North Fond du Lac technician installs the replacement part with proper brazing techniques for sealed-system components, recovers refrigerant before opening the circuit, pulls a 500-micron vacuum on reassembly, and recharges to the manufacturer-specified weight.
We run the heat pump through complete heating and cooling cycles, verify pressures match the manufacturer chart, confirm the defrost cycle activates correctly, and check the temperature differential across the coil meets specification.

Heat pump repair in North Fond du Lac 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 North Fond du Lac 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 North Fond du Lac, WI home to identify and fix the root cause.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in North Fond du Lac and surrounding Wisconsin communities every day of the year including holidays. A failed heat pump in freezing weather is a genuine emergency — indoor temperatures can drop below 40 degrees within hours, putting water pipes at risk of freezing and bursting. Our emergency technicians are dispatched with fully stocked vehicles carrying capacitors, contactors, defrost boards, fan motors, and refrigerant so the most common failures can be repaired on the first visit. Call our North Fond du Lac emergency line any time and we will have a technician on the way to your property as quickly as possible.
Most heat pump repairs in North Fond du Lac 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 North Fond du Lac home with a fully stocked truck to minimize return trips and keep your downtime as short as possible.
