A clear, step-by-step approach to every heat pump repair project we take on.
KIC Refrigeration begins every heat pump repair in Sunnyvale, CA 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 Sunnyvale 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 Sunnyvale, CA 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.
Common questions about heat pump repair costs, timelines, and what to expect.
Heat pump repair in Sunnyvale 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 Sunnyvale property, so you know exactly what the repair will cost.
KIC Refrigeration provides a comprehensive workmanship warranty on all heat pump repairs performed in Sunnyvale, CA. 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.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Sunnyvale and surrounding California 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 Sunnyvale emergency line any time and we will have a technician on the way to your property as quickly as possible.
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 Sunnyvale 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.
