For homeowners and property managers who want it done right, Racine HVAC Company handles the full range of heating and cooling work across Racine County. Furnace diagnostics when the heat goes out on a January night. AC service when the system stops keeping up in July. Full system replacements when a unit has reached the end of its run. Whatever the equipment, whatever the season, we scope the job on the call and get it scheduled.
No guesswork. No shortcuts. No rushed diagnosis.
We serve residential and commercial customers throughout Racine and the surrounding area, seven days a week from 7:00 AM to 8:00 PM.
Whether this is your first HVAC repair or your tenth, the work we cover runs from a single-component fix to a full system swap. We handle air conditioners, furnaces, heat pumps, mini-splits, ductwork, thermostats, and indoor air quality equipment. A straightforward choice for homeowners and property managers, we keep the scope clear on the call before anything is scheduled.
When an air conditioner stops cooling or starts cycling irregularly, the cause is usually one of a handful of faults: a refrigerant leak, a failing capacitor, a dirty evaporator coil, or an airflow problem in the duct system. The visit covers a full diagnostic before any parts are discussed. If uneven temperatures are the complaint, we check static pressure and airflow alongside the mechanical components.
A furnace blowing cold air, a burner that won't stay lit, or a blower running without producing heat all point to specific fault patterns that show up regularly in Wisconsin winters. The diagnostic visit covers the heat exchanger, the ignition system, the blower assembly, and the controls. We confirm what the system needs before quoting the repair.
Heat pump problems often show up as poor heating performance in cold weather or a system that runs constantly without reaching setpoint. We diagnose the refrigerant circuit, the reversing valve, and the defrost controls. For installation, the featured section below covers cold-climate units in more detail.
A full system replacement is a different conversation from a repair call. Equipment sized for the space rather than for the last unit makes a real difference in comfort and operating cost. We assess the existing ductwork, the load on the space, and the fuel source before recommending equipment. The rate is confirmed before anything is ordered.
Reach out and we'll work out what it needs.
Leaking ductwork loses conditioned air before it reaches the rooms it is supposed to serve. The result is uneven temperatures, higher energy use, and a system that runs longer than it should. We locate leaks, seal the connections, and inspect for sections that need replacement. Most homes notice a measurable difference in airflow and room temperature once the sealing is complete.
A thermostat replacement is straightforward when the wiring is compatible, and most modern smart controls work with existing forced-air systems. We confirm compatibility before the install and walk through the setup once it is done. If the existing wiring needs attention, we address that as part of the same visit.
Forced-air heating pulls air through the system repeatedly, and what goes in comes back out. Whole-home filtration and air purification equipment installs directly into the air handler, treating the air before it circulates. For homes with dry winter air, a whole-home humidifier is a natural addition. The featured section below covers that installation in detail.
A cooling tune-up covers the condenser coils, refrigerant charge, electrical connections, and thermostat calibration. A heating tune-up covers the burner assembly, heat exchanger, blower motor, and filter. Running through both before the season starts reduces the chance of a breakdown when the equipment is under the most load.
We'll go through what the service covers before it is booked.
Systems around here run into the same few faults, and some of them cannot wait. A furnace that stops working in February, a heat pump that locks out overnight, a boiler that loses pressure before a cold front moves in. We take emergency calls every day from 7:00 AM to 8:00 PM and get to the diagnostic as quickly as the schedule allows.
Heating checked. Cooling checked. Airflow measured.
The system is checked before parts are quoted. That means the technician who comes out confirms the fault before any repair cost is discussed. Emergency work follows the same process as a scheduled call, just faster.
Racine County winters are long and genuinely cold. Lake Michigan keeps temperatures from dropping as sharply as they do further inland, but it also pulls moisture into the air and drives wind chills that put real pressure on heating equipment. A furnace running through January and February in this area works harder than one in a milder climate. The three services below come up more than any others in this area, and each one reflects something specific about what the weather here asks of a home's mechanical systems.
Gas and propane forced-air furnaces handle most of the heating load in Racine County homes. When one stops working mid-winter, the call is urgent. The repair visit covers the ignition system, the heat exchanger, the gas valve, and the blower. If the heat exchanger is cracked or the repair cost approaches what a replacement would run, we say so honestly. We are honest about when a system still has life in it, and equally honest when it does not.
Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which puts them well within the range of a Wisconsin winter. The question of whether a heat pump works here is largely settled. What matters now is equipment selection, proper sizing, and a clean installation. We size the unit to the space, confirm the existing air handler can support it, and walk through what the install involves before anything is scheduled. State and utility incentives have made these upgrades more accessible in recent years.
Call and we'll get the air running right.
Forced-air heat dries indoor air, and Racine winters are long enough that the effect adds up. Dry air is harder on woodwork, harder on respiratory health, and harder on sleep. A whole-home humidifier installs directly into the air handler and introduces moisture into the air stream as it circulates through the house. The install involves connecting to the air handler and the existing duct system. The system is set to a target humidity level and operates automatically. Call and we'll handle the furnace, the AC, and the ductwork.
A quick tune-up and a full system swap are two different jobs, and so are a single-family home and a commercial property. We work across both. Residential calls cover everything from a thermostat replacement to a full central air installation. Commercial work includes rooftop units covered as well as residential, along with multi-zone systems and the equipment common in light commercial buildings across Racine County.
Built for homeowners. Ready for property managers. Ready for your system.
Doing it properly the first time is the whole point. That applies whether the property is a single-family home, a rental unit, or a commercial building with a rooftop unit that has been running since spring.
Boilers heat the living space by circulating hot water through radiators or radiant floor systems. They are space-heating equipment, not domestic water heaters, and the service call covers the heat exchanger, the circulator pump, the pressure and temperature controls, and the expansion tank. When a boiler is losing pressure, cycling off on limit, or failing to distribute heat evenly, the diagnostic visit identifies the fault before a repair is quoted. Replacement involves sizing the new unit to the existing hydronic system and confirming the distribution side is in good condition.
Pricing on HVAC work depends on what the system actually needs, and that is confirmed on the call or during the diagnostic visit. When you call, we go through what the service covers, what the visit includes, and what the rate is before anything is scheduled. Repair quotes follow the diagnostic. Replacement quotes follow the equipment assessment. You get the rate before work begins, and any questions about what it covers get a straight answer.
We provide heating and cooling service throughout Racine and the communities around it. That includes Mount Pleasant, Caledonia, Sturtevant, Wind Point, South Milwaukee, Oak Creek, Kenosha, and Burlington. If you are in Racine County or the wider southeast Wisconsin area and need a furnace repaired, an AC serviced, or a full system replaced, we cover your area.
A furnace that short-cycles, fails to ignite consistently, produces a burning or metallic smell, or runs but does not bring the house to temperature is showing signs of a developing fault. Unusual sounds from the blower or the burner assembly, or a heat exchanger that has not been inspected in several years, are also worth attention before a Wisconsin winter. A diagnostic visit identifies the specific fault so the repair or replacement decision is based on what the system actually needs.
The diagnostic covers the ignition system, the heat exchanger, the gas valve, the burner assembly, the blower motor, and the limit and safety controls. Each component is checked in sequence so the fault is isolated before any parts are discussed. The repair quote follows from what the diagnostic finds, not from a general estimate.
Cold-climate heat pump installation starts with a load calculation for the space, because the equipment has to be sized to handle the actual heating demand at the temperatures Racine sees, including stretches below zero. The unit selection follows from that calculation, not from whatever model happens to be available. We also confirm that the existing air handler and duct system can support the new equipment before anything is ordered.
Older heat pump technology lost most of its efficiency below around 30 degrees Fahrenheit, which made it a poor fit for southeastern Wisconsin winters. Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which covers what Racine actually experiences. The key is selecting a unit rated for that temperature range rather than a standard residential model.
A whole-home humidifier installs directly into the air handler and duct system, introducing moisture into the air stream as the furnace runs. The installation involves connecting the unit to the air handler, the duct system, and a water supply line. Once installed, it operates automatically and maintains a target humidity level throughout the house without requiring manual refilling.
Uneven temperatures, rooms that never reach setpoint, or a system that runs constantly without satisfying the thermostat can all point to either an equipment fault or a duct system problem. The diagnostic visit checks static pressure and airflow alongside the mechanical components of the equipment. If the ducts are leaking or undersized, that gets identified separately from the equipment assessment.
The outdoor unit inspection covers the condenser coil, the fan motor and blade, the capacitor, the refrigerant charge, and the electrical connections at the disconnect. On a heat pump, the reversing valve and the defrost controls are also checked. Any refrigerant work is handled as part of the same visit if the charge is found to be off.
At the indoor unit, the technician checks the filter condition, the blower motor and wheel, the evaporator coil on a cooling system, the heat exchanger on a furnace, and the thermostat wiring and calibration. Airflow through the supply and return is also assessed. If the indoor unit is part of a heat pump system, the refrigerant circuit is checked from both ends.
Additional charges come up when the repair requires parts beyond what a standard diagnostic covers, when the equipment is in a difficult location that adds time to the visit, or when a second fault is discovered during the repair of the first. Each of those is presented as a separate quote before the additional work proceeds. You are not charged for work you have not agreed to.
A burning smell at the start of the heating season is often dust burning off the heat exchanger after the system has been sitting idle, and it typically clears within a few minutes of the furnace running. A persistent burning smell, or one that smells like melting plastic or electrical components, points to a fault that needs a diagnostic visit. A musty smell usually indicates mold or mildew growth somewhere in the duct system or on the evaporator coil.
A system that has not been serviced in a year or more, one that is approaching ten years of age, or one that is heading into a Wisconsin winter without a recent tune-up is a good candidate for an inspection. Catching a developing fault before the heating season is less disruptive and usually less expensive than diagnosing it during a breakdown. A fall furnace inspection covers the heat exchanger, burners, ignition system, and blower before the system is under full load.
Efficiency drops in aging equipment as components wear, heat exchangers accumulate deposits, and refrigerant charges drift. A system that is running longer cycles to reach setpoint, or one that is cycling on and off more frequently than it used to, is working harder than it should for the same output. A tune-up can recover some of that efficiency, but a system past a certain age may be costing more to run than a replacement would.
An undersized system runs almost continuously without reaching setpoint, struggles to maintain temperature during the coldest or hottest stretches of the year, and wears out components faster than a properly sized unit would. In Racine, that usually shows up as a system that cannot keep up during a January cold snap or a July heat stretch off the lake. A load calculation confirms whether the equipment matches the space.
The diagnostic starts with confirming that the thermostat is calling for the right mode and that the system is responding to the signal. From there, the technician works through the refrigerant circuit on a cooling system or the combustion and heat transfer components on a heating system. The fault is isolated to a specific component before any repair is quoted.
Racine HVAC Company is available every day from 7:00 AM to 8:00 PM for heating repairs, cooling service, system installations, and everything in between. Whether the furnace stopped working or you are ready to replace an aging system, the call starts the process.
No guesswork. No shortcuts. No rushed diagnosis.

| Boiler & Hydronic Heating Service |
| Homes with radiators or radiant floor heating that are losing pressure or heating unevenly | A boiler losing pressure or cycling off on limit points to a specific fault pattern. The diagnostic identifies it before a repair is quoted. |
| Whole-Home Humidifier Installation |
| Racine homes where forced-air heat is drying out the air through a long winter | Dry winter air is harder on woodwork and respiratory health. A whole-home unit operates automatically once installed, with no manual refilling. |
| Emergency HVAC Service |
| Any customer whose heating or cooling system has stopped working and cannot wait for a scheduled visit | Emergency calls follow the same diagnostic process as a scheduled visit. The fault is confirmed before any parts or repair cost are discussed. |
| Furnace Repair & Replacement |
| Racine County homeowners with a gas or propane forced-air furnace that has stopped working or is losing efficiency | If the heat exchanger is cracked or the repair cost approaches replacement cost, we say so. We are honest about when a system still has life in it. |
How often should we schedule HVAC maintenance and tune-ups?
Most heating and cooling systems benefit from a tune-up once a year for each mode they run. A furnace or heat pump in heating mode is best checked in the fall before the season starts. An air conditioner or heat pump in cooling mode is best checked in the spring. Racine winters are long and put real demand on heating equipment, so a fall inspection before the cold sets in is the one we hear about most often. A system that has not been serviced in two or more years is worth scheduling regardless of season.
What are the signs that an air conditioner needs attention before it fails completely?
An AC that is running longer cycles than it used to, struggling to keep up on hot July days, making a new noise at startup or shutdown, or producing a refrigerant smell near the outdoor unit is showing early signs of a developing fault. Warm air from the vents when the system is set to cool, or ice forming on the refrigerant lines, both point to a problem worth diagnosing before the unit stops working altogether. Catching it early usually means a simpler repair.
How do we decide whether to repair or replace a system?
The decision comes down to what the diagnostic finds, how old the equipment is, and what the repair cost looks like relative to a replacement. A system under ten years old with a single failed component is usually worth repairing. A system past fifteen years with a cracked heat exchanger, a failing compressor, or a repair bill that approaches half the cost of a new unit is often better replaced. We go through the diagnostic findings with you and give you an honest read on where the system stands before you decide anything.
System Checked Before Parts Are Quoted
Every visit starts with a full diagnostic. We confirm the fault before any parts or repair costs are discussed, so the quote reflects what the system actually needs.
What causes one room to be hotter or colder than the rest of the house?
Uneven temperatures usually trace back to one of three things: a duct system that is leaking or undersized for that part of the house, an equipment fault that is reducing overall airflow, or a load mismatch where the system is not sized correctly for the space. We check static pressure and airflow alongside the mechanical components of the equipment during a diagnostic visit, so the cause gets identified rather than guessed at. Duct sealing resolves the problem when leaks are the source.
What do strange noises from the HVAC unit usually mean?
A rattling sound often points to a loose panel, a failing blower wheel, or debris in the outdoor unit. A grinding or squealing noise from the blower assembly usually means a motor bearing is wearing. A clicking or banging at startup can indicate an ignition fault on a furnace or a failing capacitor on an AC. A hissing sound near the refrigerant lines suggests a possible leak. None of these are sounds to wait on, because most of them get worse with continued operation. A diagnostic visit identifies the source.
How does a dirty filter or coil affect system performance?
A clogged filter restricts airflow through the air handler, which forces the blower to work harder and reduces the amount of conditioned air reaching the rooms. Over time, restricted airflow causes the evaporator coil to ice over on a cooling system, or the heat exchanger to overheat on a furnace. A dirty evaporator or condenser coil reduces heat transfer efficiency, which means the system runs longer cycles to reach setpoint and uses more energy doing it. Replacing the filter regularly is the single lowest-cost maintenance step a homeowner can take.
Emergency No-Heat and No-Cool Calls Handled
We take emergency calls every day from 7:00 AM to 8:00 PM. A furnace that stops working in a Wisconsin winter or an AC that fails in July gets the same thorough diagnostic as a scheduled visit.
What does choosing between a furnace and a heat pump involve?
The right choice depends on the home's existing infrastructure, the heating load, and what the homeowner wants from the system long-term. A gas furnace delivers high-temperature heat quickly and is a natural fit where gas is already connected. A cold-climate heat pump handles both heating and cooling from a single system and runs efficiently down to around -15 degrees Fahrenheit, which covers what Racine actually sees in a hard winter. Homes that currently have electric resistance heat often see the biggest operating cost improvement from a heat pump switch. We go through both options on the call and size from there.
How do ductwork leaks affect energy bills?
When ducts leak, conditioned air escapes into unconditioned spaces like attics, crawl spaces, and wall cavities before it reaches the rooms it is meant to serve. The system compensates by running longer, which raises energy use without improving comfort. In a Racine home running the furnace through a long winter, duct losses add up over months. Sealing the leaks reduces the run time and brings the energy use back in line with what the equipment is actually rated to deliver.
Older Systems and New Installs Both Covered
Whether the equipment is a decades-old boiler or a new cold-climate heat pump going in for the first time, we work across the full range of residential and commercial HVAC equipment in Racine County.
What does a short-cycling system mean and what causes it?
Short-cycling is when the system turns on, runs briefly, shuts off, and then restarts before the space has reached setpoint. On a furnace, it often means the limit switch is tripping due to restricted airflow or an overheating heat exchanger. On an AC or heat pump, it can point to an oversized system, a refrigerant charge that is off, or a failing compressor. Short-cycling puts extra wear on the equipment because startup is the most mechanically demanding part of each cycle. A diagnostic visit identifies the specific cause.
Is older equipment worth repairing, or does age alone make replacement the better choice?
Age alone does not make replacement the right answer, but it is a factor in the calculation. A fifteen-year-old furnace with a straightforward igniter replacement is still worth repairing if the heat exchanger is sound and the rest of the system is in reasonable condition. The same furnace with a cracked heat exchanger or a failing blower motor is a different conversation. We assess what the diagnostic finds rather than applying a blanket age rule. If a system still has practical life in it, we say so.
How are emergency no-heat or no-cool calls handled?
Emergency calls are taken every day from 7:00 AM to 8:00 PM. When you call, we go through what the system is doing and what the symptoms are so the visit is scoped before anyone arrives. The diagnostic on an emergency call follows the same process as a scheduled visit: the fault is confirmed before any repair cost is discussed. A furnace that stops working in February or an AC that goes down during a July heat stretch off the lake are the calls we take most seriously, and we get to the diagnostic as quickly as the schedule allows.
Call us to go through what your system needs, get a rate before anything is scheduled, and ask any questions about what the visit covers.
