How our NATE-certified technicians deliver quality heat pump repair results from start to finish.
Our Darien technician evaluates your heat pump by running it through a complete heating cycle and cooling cycle. We verify reversing valve solenoid operation, check defrost board timing, and measure output temperatures to determine if the system is switching modes correctly.
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.
KIC Refrigeration repairs your Darien, IL heat pump with precision. For sealed-system work, we recover refrigerant with a certified recovery machine, braze with nitrogen flowing to prevent scale, pressure test with dry nitrogen to 300 PSI, evacuate to below 500 microns, and weigh in the exact factory charge.
Our Darien crew verifies the repair by running the system in both modes. We confirm superheat and subcooling are within 2 degrees of target, the defrost cycle initiates and terminates properly, and the temperature split across the air handler is 15 to 20 degrees in cooling and 20 to 30 degrees in heating.

Heat pump repair in Darien 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 Darien property, so you know exactly what the repair will cost.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Darien and surrounding Illinois 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 Darien emergency line any time and we will have a technician on the way to your property as quickly 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 Darien property.
KIC Refrigeration provides a comprehensive workmanship warranty on all heat pump repairs performed in Darien, IL. Replacement parts carry manufacturer warranties that range from 1 to 10 years depending on the component — compressors typically carry 5 to 10 year manufacturer warranties, while electrical components like capacitors and contactors carry 1 to 2 year warranties. If a part we install fails within the warranty period, we replace it at no charge for the part and provide the labor to install it. KIC Refrigeration handles all warranty documentation and claims on your behalf so you never have to chase paperwork. Ask your technician about specific warranty terms during your service appointment.
