A clear, step-by-step approach to every heat pump repair project we take on.
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.
At your Middlebury property, our technician connects digital manifold gauges and measures suction pressure, discharge pressure, liquid line temperature, and suction line temperature. We calculate superheat and subcooling to determine if the charge is correct or if there is a restriction in the metering device or a refrigerant leak.
KIC Refrigeration repairs your Middlebury, VT 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.
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.
Common questions about heat pump repair costs, timelines, and what to expect.
Heat pump repair in Middlebury 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 Middlebury property, so you know exactly what the repair will cost.
Most heat pump repairs in Middlebury 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 Middlebury home with a fully stocked truck to minimize return trips and keep your downtime as short 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 Middlebury, VT home to identify and fix the root cause.
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 Middlebury property.
Real feedback from customers across the country about the quality of our work.
"Mini split repair was done right the first time. The outdoor unit had a refrigerant leak and they found it, fixed it, and recharged the system same day."
"KIC Refrigeration installed a new furnace for us last winter. The team was respectful of our home, wore boot covers, and cleaned up everything. Top notch."
"Emergency repair on a Sunday night and they still showed up within the hour. Furnace was back up and running before bedtime. Lifesavers."
