Trusted by Sun Prairie property owners for heat pump repair, AC service, furnace maintenance & complete HVAC installation throughout Wisconsin.
NATE-certified technicians providing the complete range of heating and cooling services.
Professional smart thermostat installation goes beyond mounting and Wi-Fi pairing. Technicians verify your system has the necessary common wire, confirm compatibility with multi-stage heating and cooling equipment, and program setpoints and schedules tailored to your household for immediate energy savings.
An annual air conditioning tune-up catches refrigerant leaks, worn contactor points, and degraded fan motors before they cascade into compressor damage. Technicians measure temperature differential across the coil, verify amp draws, and confirm proper subcooling to protect your investment.
Replacing an aging HVAC system with properly sized, high-efficiency equipment can reduce energy costs by 30 to 50 percent. Professional installation covers equipment selection, ductwork modifications, refrigerant line installation, electrical upgrades, and thorough commissioning to verify rated SEER and AFUE output.
A professional HVAC inspection evaluates the complete system from furnace combustion and heat exchanger integrity to air conditioning refrigerant charge and electrical safety. Technicians document equipment age, efficiency ratings, and any code violations to give you a clear picture of system health.
Preventive furnace maintenance protects your household by identifying cracked heat exchangers, carbon monoxide risks, and failing ignition components before they cause a breakdown. Annual service preserves rated AFUE efficiency and ensures consistent airflow through cleaned blower assemblies.
Upgrading to a modern heat pump delivers dual-mode heating and cooling from a single system, with top-tier models achieving 10+ HSPF and 20+ SEER2 ratings. Proper installation includes Manual J load calculations, refrigerant line sizing, and electrical panel verification for reliable year-round comfort.
When your heat pump struggles to maintain temperature or runs continuously without reaching setpoint, the problem often traces to refrigerant leaks, failing capacitors, or degraded reversing valves. Skilled technicians restore rated HSPF and SEER performance through systematic component-level troubleshooting.
Ductless mini-split systems deliver zoned comfort without invasive ductwork, making them ideal for additions, garages, and older homes. Professional installation includes refrigerant line routing, condensate management, and electrical circuit provisioning to achieve rated SEER performance up to 33 in top models.
Leaking and disconnected ductwork wastes up to 30 percent of conditioned air before it reaches living spaces, forcing your HVAC system to work harder and driving up energy costs. Professional duct repair seals joints, replaces damaged sections, and restores proper static pressure balance.
Ductless mini-split systems require specialized diagnostics for inverter-driven compressors, electronic expansion valves, and multi-zone communication boards. Our technicians resolve issues including refrigerant leaks at flare connections, blinking error codes, frozen evaporator coils, and failing fan motors.
Air conditioning failures range from simple capacitor replacements to complex compressor and refrigerant circuit repairs requiring EPA Section 608 certified handling. Our technicians diagnose the root cause using superheat and subcooling measurements, amp draws, and pressure readings to restore full cooling output.
When your boiler produces inconsistent heat, unusual noises, or pressure fluctuations, the root cause often involves sediment buildup, failing motorized valves, or degraded seals within the hydronic loop. Experienced technicians restore system balance and verify safe operation through combustion analysis.
Sudden HVAC failures often stem from compressor lockout, blown transformer fuses, failed gas valves, or tripped high-pressure switches. Emergency repair service provides same-day response with technicians equipped to diagnose and resolve critical faults across all major heating and cooling equipment brands.
Indoor air quality suffers when ductwork harbors years of accumulated particulate matter, allergens, and biological growth. Thorough duct cleaning addresses every branch run, main trunk line, and register boot using agitation tools and high-powered vacuum extraction to restore clean airflow.
Annual dryer vent cleaning reduces fire risk, lowers energy consumption, and extends appliance lifespan. Our technicians clear the full vent path from the dryer connection to the exterior hood, remove bird nests or debris from the termination point, and confirm unrestricted exhaust flow.
Sun Prairie property owners know that HVAC emergencies do not wait for business hours. A failed furnace in January risks frozen pipes, and a dead air conditioner in August creates dangerous indoor heat. With 40,875 residents depending on reliable climate control, KIC Refrigeration provides 24/7 emergency HVAC service built to respond fast and fix the problem right the first time.

We recommend professional HVAC maintenance at least twice per year for Sun Prairie homeowners — once in spring to prepare your cooling system and once in fall to prepare your heating system. Each tune-up includes a comprehensive multi-point inspection covering filter replacement, refrigerant level verification, electrical connection tightening, thermostat calibration, condensate drain clearing, and performance testing. For the heating check, technicians also inspect the heat exchanger for cracks, test safety switches, and verify gas pressure on furnaces and boilers. Routine maintenance catches small problems — like a failing capacitor or a dirty flame sensor — before they cause complete system failures. Industry data shows that well-maintained HVAC systems last 15 to 20 years compared to 10 to 12 years for neglected equipment, and they operate 15 to 25 percent more efficiently throughout their lifespan.
The ideal time for HVAC replacement in Sun Prairie is during the shoulder seasons — spring and fall — when demand is lower, equipment availability is highest, and scheduling is more flexible. Contractors are less booked during these periods, which means faster installation timelines and potentially more competitive pricing. You are also more likely to find manufacturer rebates, utility incentive programs, and promotional financing during off-peak months. From a technical standpoint, moderate temperatures allow your new system to be commissioned and tested under less extreme conditions. However, KIC Refrigeration completes HVAC installations year-round in Wisconsin and can often start within days of your approved estimate, even during peak summer or winter demand. If your current system is showing signs of failure, do not wait for the perfect season — a planned replacement is always better than an emergency one.
Most HVAC installations, major equipment replacements, and significant ductwork modifications in Sun Prairie require a mechanical permit from the local building department. This applies to furnace and air conditioner replacements, heat pump installations, boiler swaps, and new ductless mini split systems. Minor repairs like part replacements and refrigerant recharges typically do not require permits. KIC Refrigeration handles all permitting, code compliance documentation, and scheduling of final inspections on your behalf — you do not need to visit any government office or coordinate with inspectors. Permits exist to ensure your system is installed safely and to code, which protects your home and preserves your equipment warranty. Unpermitted work can create liability issues and complicate future home sales. We ensure every project meets current Wisconsin mechanical codes and International Mechanical Code standards.
