HVAC Services in Oshkosh

NATE-certified technicians providing the complete range of heating and cooling services.

Heat Pump Repair

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.

Mini Split Installation

A professionally installed mini-split eliminates the energy losses associated with traditional ductwork while providing independent temperature control per zone. Technicians mount indoor heads at optimal height, route linesets with proper insulation, and commission each zone for verified heating and cooling output.

HVAC Inspection

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.

AC Tune-Up

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.

Mini Split Repair

Mini-split repair demands familiarity with variable-speed compressor technology and manufacturer-specific diagnostic protocols from Mitsubishi, Fujitsu, Daikin, and LG. Technicians trace electrical faults, recharge refrigerant to factory specifications, and replace condensate pumps to restore silent, efficient operation.

Heat Pump Installation

Selecting the right heat pump means matching BTU capacity to your structure while accounting for climate zone, insulation levels, and existing ductwork. Professional installation ensures proper refrigerant charge, correct defrost timing, and verified auxiliary heat staging for demanding winter conditions.

Smart Thermostat Installation

Upgrading to a smart thermostat enables precise scheduling, remote access, and energy usage reporting that can reduce heating and cooling costs by 10 to 15 percent. Professional installation ensures correct wiring to your HVAC system, including C-wire verification and multi-stage equipment compatibility.

Furnace Tune-Up

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.

Dryer Vent Cleaning

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.

HVAC Installation

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.

Air Duct Cleaning

Over time, air ducts accumulate dust, pet dander, mold spores, and construction debris that degrade indoor air quality and restrict airflow. Professional duct cleaning uses negative-pressure HEPA-filtered vacuums and rotary brush systems to remove contaminants from supply and return plenums.

Boiler Repair

Boiler systems demand specialized knowledge of hydronic circuits, expansion tanks, pressure relief valves, and combustion analysis. Our technicians diagnose issues ranging from kettling and low water pressure to faulty zone valves and circulator pump failures across gas, oil, and electric units.

AC Repair

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.

Air Duct Repair

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.

Emergency HVAC Repair

When your heating or cooling system fails unexpectedly, rapid diagnosis is critical to minimizing discomfort and preventing secondary damage like frozen pipes or heat-related illness. Emergency technicians isolate the fault, whether electrical, mechanical, or refrigerant-related, and execute repairs on the spot.

Yes. KIC Refrigeration provides around-the-clock emergency heating and cooling repair throughout Oshkosh and surrounding Wisconsin communities. Whether your furnace fails during a cold snap and pipes are at risk of freezing, your air conditioner dies during a dangerous heat wave, or you detect the smell of gas near your equipment, our technicians respond quickly.

We do not charge extra trip fees for after-hours calls, and our dispatchers are trained to triage situations over the phone so the right technician arrives with the right equipment. Call us anytime and we will have a crew on the way.

How long does a full HVAC system installation take in Oshkosh?

Most residential HVAC installations in Oshkosh, WI are completed in 1 to 3 days depending on the system type, condition of existing ductwork, and complexity of the project. A straightforward furnace and air conditioner replacement on existing ductwork typically takes a single day — our crews arrive in the morning and commission the new system by afternoon. Heat pump conversions, ductless multi-zone installations with line sets routed through walls, and projects requiring new or modified ductwork may take 2 to 3 days. Commercial installations and whole-building systems can extend to a week. We schedule around your availability, coordinate all permits and inspections, and protect your flooring and walls throughout the process. Every installation concludes with a full system commissioning including airflow verification and refrigerant charge confirmation.

What HVAC brands does KIC Refrigeration install in Oshkosh, WI?

KIC Refrigeration installs and services all major HVAC equipment manufacturers in Oshkosh including Carrier, Lennox, Trane, Daikin, Goodman, Rheem, York, Bryant, American Standard, Mitsubishi, and Fujitsu. For ductless mini split systems, we specialize in Mitsubishi, Daikin, and Fujitsu units which are the market leaders in inverter-driven technology. We are not locked into a single manufacturer or distributor, which means our recommendations are based entirely on what best fits your home size, budget, efficiency goals, and existing infrastructure. Each brand offers different warranty structures, SEER2 ratings, and feature sets — from basic single-stage units to premium variable-speed communicating systems. Our NATE-certified technicians install every unit strictly to manufacturer specifications and register all warranties on your behalf.

How much does HVAC repair cost in Oshkosh, WI?

HVAC repair costs in Oshkosh typically range from $150 to $500 for minor fixes such as capacitor replacement, contactor swaps, or thermostat wiring issues. Mid-range repairs like blower motor replacement or refrigerant recharging run $500 to $1,200. Major repairs — including compressor replacement, heat exchanger repair, or evaporator coil swap — cost $1,200 to $2,500 or more depending on equipment brand and system type. The final price depends on whether you have a furnace, heat pump, air conditioner, boiler, or ductless mini split, as parts and labor vary significantly between system types. Our NATE-certified technicians diagnose the issue accurately on the first visit, and KIC Refrigeration provides a written estimate with transparent pricing before any work begins. We never charge a diagnostic fee when you proceed with the recommended repair.

What is the best time of year to replace an HVAC system in Oshkosh?

The ideal time for HVAC replacement in Oshkosh 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.

Does KIC Refrigeration offer financing for HVAC installations in Oshkosh?

Yes. KIC Refrigeration offers flexible financing options for HVAC installations in Oshkosh, WI, including low-interest plans, deferred interest same-as-cash programs, and extended payment terms that make it easier to invest in high-efficiency equipment without a large upfront cost. Approved applicants can often finance a complete system replacement for less than $100 per month. We also help Oshkosh homeowners identify and apply for available financial incentives including utility company rebates on high-efficiency equipment, manufacturer promotional pricing, and federal tax credits such as the 25C Residential Clean Energy Credit which provides up to $2,000 for qualifying heat pump installations and up to $600 for qualifying furnaces and air conditioners. Between financing, rebates, and tax credits, the effective cost of a new high-efficiency HVAC system is often significantly lower than the sticker price.
