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 Derry, NH 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 Derry 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 Derry 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 Derry property, so you know exactly what the repair will cost.
The general rule is to repair if the system is under 10 years old and the repair costs less than 50 percent of a replacement. Heat pumps over 12 to 15 years old — especially units still running on R-22 refrigerant — are often better replaced with a new R-410A system that offers higher SEER2 and HSPF2 efficiency ratings and lower operating costs. A new variable-speed heat pump can reduce your Derry energy bills by 30 to 40 percent compared to an aging single-stage unit. KIC Refrigeration gives honest repair-versus-replace advice based on your specific equipment age, condition, and repair history rather than pushing unnecessary replacements.
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 Derry, NH home to identify and fix the root cause.
