From initial contact to final verification — here is how we handle heat pump repair.
KIC Refrigeration begins every heat pump repair in Millsboro, DE 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.
We connect manifold gauges to check suction and discharge pressures, calculate superheat and subcooling, and compare readings to the manufacturer charge chart. Incorrect pressures reveal leaks, restrictions, or compressor issues.
Our Millsboro 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.
KIC Refrigeration does not consider your Millsboro, DE 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.

Heat pump repair in Millsboro 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 Millsboro property, so you know exactly what the repair will cost.
Most heat pump repairs in Millsboro 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 Millsboro home with a fully stocked truck to minimize return trips and keep your downtime as short as possible.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Millsboro and surrounding Delaware 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 Millsboro emergency line any time and we will have a technician on the way to your property as quickly as possible.
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 Millsboro, DE home to identify and fix the root cause.
Our reputation is built on certified technicians, honest pricing, and results that last.
