Your satisfaction is guaranteed.
From initial contact to final verification — here is how we handle heat pump repair.
Our Potomac 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.
KIC Refrigeration performs a complete refrigerant circuit analysis on your Potomac, MD 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.
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.
Our Potomac 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 Potomac 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 Potomac property, so you know exactly what the repair will cost.
KIC Refrigeration repairs every major heat pump brand installed in Potomac homes and businesses — Carrier, Trane, Lennox, Rheem, Goodman, Daikin, York, Bryant, Amana, Mitsubishi, Fujitsu, and LG. Our NATE-certified technicians are trained on both conventional ducted split systems and ductless mini-split heat pumps across all tonnage ratings from 1.5 to 5 tons. We work with every common refrigerant including R-410A, R-22, R-32, and R-454B.

Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Potomac and surrounding Maryland 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 Potomac 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 Potomac property.
