How our NATE-certified technicians deliver quality heat pump repair results from start to finish.
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 Markham 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 Markham, 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.
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 Markham 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 Markham property, so you know exactly what the repair will cost.
KIC Refrigeration repairs every major heat pump brand installed in Markham 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. Whether your system is a 30-year-old R-22 unit or a brand-new variable-speed inverter model, KIC Refrigeration has the diagnostic tools, replacement parts access, and technical knowledge to repair it correctly at your Markham property.
Most heat pump repairs in Markham 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 Markham home with a fully stocked truck to minimize return trips and keep your downtime as short 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 Markham property.
Our reputation is built on certified technicians, honest pricing, and results that last.
"Boiler kept cycling on and off. Technician found a faulty thermocouple and replaced it on the spot. No nonsense, no upselling. Just good honest 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."
"Called for a second opinion on an HVAC installation quote from another company. They came in significantly lower with better equipment. Glad I shopped around."
