Quick response. Careful diagnosis. Clean install.
The sooner you call, the sooner your comfort is back, and that matters most when the furnace goes quiet on a January night or the AC stops cooling during a humid Illinois August. A system that will not turn on, a furnace blowing cold air, an AC running constantly without dropping the temperature, or a unit that short-cycles and shuts off every few minutes are all situations worth calling about as soon as they appear.
We answer calls every day from 5:00 AM to 9:30 PM. When you call, the rate and the scope of the visit are discussed on the phone before anything is scheduled. You know what the call covers before anyone comes out. We track down the problem fast.
A home that heats and cools right is a comfortable home, and the same is true for a commercial space where employees work and customers walk in. The services below cover the full range of residential and commercial HVAC work, from a single repair call to a complete system replacement.
Warm air from the vents and uneven cooling across the house are two of the most common complaints we hear in summer. The cause is often refrigerant level or a failing compressor, not simply a thermostat setting. A proper diagnosis covers the condenser, the compressor, refrigerant charge, and the evaporator coil before any parts are quoted. Central air that is not keeping up with the outdoor temperature deserves a full look, not a quick guess.
A furnace blowing cold air is one of the more alarming calls of the heating season, but it is frequently a flame sensor or ignition issue rather than a sign the equipment needs to be replaced. Heating repair starts with a proper diagnosis: checking ignition, inspecting the heat exchanger, confirming airflow, and testing controls. That is how you know whether a repair makes sense or whether replacement is the right conversation to have.
A heat pump that struggles to hold temperature when outdoor conditions drop may need supplemental heat diagnosis rather than a compressor replacement. Heat pumps that are not heating or not cooling often have a refrigerant, reversing valve, or airflow issue that a targeted diagnosis can isolate. We handle heat pump repair and maintenance for both residential and commercial systems.
Ductless mini-splits are a practical solution for additions, finished basements, sunrooms, and any space where running ductwork is not realistic. We install and repair mini-split systems, and we diagnose units that are not heating or cooling to the set temperature. If you are adding conditioned space to a property, a ductless system is often the cleanest path.
Leaking ducts are one of the most common causes of hot and cold spots and higher-than-expected energy bills. When one room stays warmer or cooler than the rest, the duct system is worth inspecting before the equipment gets blamed. We handle ductwork repair, duct sealing, and airflow troubleshooting for systems where the equipment is running but the air is not reaching where it should.
A thermostat that is not responding, not reading the correct temperature, or not communicating with the system can make a perfectly functional HVAC system behave erratically. We install programmable and smart thermostats, and the thermostat is confirmed as communicating before sign-off on every installation. If you are upgrading to a smart control or replacing a failed unit, the call is where we scope the job and confirm compatibility.
Whole-home air filtration and air scrubbers connect directly to the existing HVAC system and treat air as it circulates through the house. If dust, allergens, or indoor air quality are a concern, a system-integrated filter or purifier addresses the problem at the source rather than room by room. We also install whole-home humidifiers for properties that dry out in winter.
Boilers and hydronic heating systems heat the living space and fall squarely in HVAC territory. We repair and replace boilers, service radiant heat systems, and diagnose hydronic heating that is not performing. If a boiler is short-cycling, leaking pressure, or failing to heat zones evenly, a diagnostic call is the right starting point.
Commercial HVAC work follows the same process as residential: the scope and the rate are discussed on the phone before the visit is scheduled. We handle commercial heating repair, commercial cooling repair, rooftop unit service, and commercial system installation for offices, retail spaces, and light commercial properties across the area. Give us a call and we will take care of it.
Champaign County sits in a true four-season climate. Summers bring sustained heat and humidity that push cooling systems hard, and Illinois winters are cold enough to test every furnace and heat pump in the area. Systems like yours are familiar ground in these neighborhoods. The services below reflect what this climate actually demands.
Central Illinois systems cycle between extreme heat and extreme cold every year, and a system that is undersized or aging struggles hardest during the peak demand weeks in January and July. When a furnace or AC reaches the point where repair costs are climbing and performance is declining, replacement is worth discussing. Replacement starts with a call to scope the job, confirm proper sizing for the space, and discuss pricing before anything is scheduled. Getting the sizing right matters as much as the equipment itself.
Modern heat pumps with supplemental heat strips handle Illinois winters, and they handle summer cooling without a separate system. For properties that are replacing aging equipment or adding conditioning to a new space, a heat pump installation is a practical option worth pricing out. Zoning and comfort-control systems can be incorporated into the installation where the layout calls for it. Scope and pricing are confirmed on the call before the job is scheduled.
Champaign summers bring sustained humidity that a central AC alone does not fully control. When a house feels uncomfortable even though the thermostat reads the right temperature, the cause of an uneven house actually investigated is often humidity rather than a heating or cooling failure. A whole-home dehumidifier connects to the existing system and runs independently of the cooling cycle, pulling moisture out of the air on its own schedule. We install and repair whole-home dehumidifiers and humidifiers for both residential and commercial properties.
Before a small issue turns into a full breakdown, a seasonal tune-up gives the system a chance to be checked when it is not already under peak load. A spring AC tune-up covers refrigerant levels, evaporator coil condition, condenser cleaning, and airflow confirmation. A fall furnace check covers ignition testing, heat exchanger inspection, filter condition, and controls. Catching a weak component before the coldest week of the year or the hottest weekend of the summer is the point of the visit.
Seasonal maintenance scheduled around your calendar is how we approach tune-up calls. When you are ready to schedule, the call is where we confirm timing and scope. One call is all it takes to get it looked at.
Scheduling an HVAC tech shouldn't be complicated. When you call, the rate for the visit is discussed on the phone and the scope is confirmed before anything is scheduled. You know what the call covers and what it costs before the work begins.
Diagnosed properly. Explained clearly. Priced before the work.
Pricing varies by the job. A diagnostic call, a repair, and a full system replacement are different scopes with different costs, and the call is where those differences get sorted out. A diagnostic visit that finds a failed capacitor is a different conversation from a visit that finds a failing compressor or a cracked heat exchanger. The price is settled before the work is scheduled, not after.
We serve Champaign as our primary area and extend throughout the surrounding communities in Champaign County and the wider region. If you are outside the city, call and we will confirm coverage for your address.
Nearby towns we serve include:
When you call, someone who knows the trade picks up and scopes the job on the phone. You describe what the system is doing, and we confirm what the visit will cover and what it will cost before anything is scheduled. The price is settled on the call, not after the technician has already come out.
Call (217) 395-3661 any day from 5:00 AM to 9:30 PM to get started.

We take emergency heating calls every day from 5:00 AM to 9:30 PM, including weekends. When you call, we scope the situation on the phone and confirm the rate before anyone is dispatched. A furnace that will not start, a heat pump stuck in auxiliary heat, or a system blowing cold air are exactly the kind of problems we take on short notice.
We serve Champaign as our primary area and cover the surrounding communities throughout Champaign County, including Urbana, Savoy, Rantoul, Mahomet, Tolono, Monticello, Fisher, and Thomasboro. If you are outside those areas, call and we will confirm whether your address falls within the service area. Coverage questions are answered on the call before anything is scheduled.
A system that has needed multiple repairs in a short period, struggles to hold the set temperature during peak demand, or has repair costs climbing toward the value of the equipment is worth evaluating for replacement. We explain what the diagnostic finds and what the repair involves before any work is authorized, so you can make that decision with the actual numbers in front of you. If replacement is the better path, we scope and price that on the same call. There is no pressure to decide before you are ready.
The price confirmed on the call covers the diagnostic visit and what was agreed during that conversation. If the diagnosis finds a repair that was not part of the original scope, we explain what it involves and what it will cost before proceeding. You are not billed for work you did not authorize. Ask what the quote covers and you get a straight answer.
The size and type of equipment affects the scope of the work, which affects the price. A repair call on a small single-zone system is a different job from a full system replacement in a larger home or commercial building. We confirm the scope and the price on the phone based on what you describe, so you have a clear picture before the visit is scheduled.
Yes. Landlords and property managers across Champaign County call us for the same range of services as residential homeowners: repair calls, seasonal maintenance, system replacements, and emergency no-heat or no-cool situations. The process is the same for every job: the scope is confirmed on the call, the price is settled before scheduling, and the work covers what was agreed.
Call (217) 395-3661 to discuss what your properties need.
Yes, and it helps. When you call, describe what you are seeing: which rooms are not reaching temperature, whether the airflow at a particular vent is weak, or whether the problem is isolated to one zone or the whole system. That information helps scope the visit before anyone comes out and makes the diagnostic more efficient when the technician arrives.
That is part of how the visit is arranged. The timing and what to expect are confirmed when the job is booked, and any questions about the visit can be addressed on the same call. If anything changes on the scheduling side, we work that out before the day of the visit rather than after.
Payment timing is confirmed on the call when the job is scoped. For most repair and service visits, payment follows the completed work. For larger jobs like system replacements, the payment structure is part of the conversation before anything is scheduled. You know what you owe and when before the work begins.
Diagnosis explained first. Code-compliant work. Clean finish.
We are open every day from 5:00 AM to 9:30 PM.

| Service | Scope of Work | Common Needs | What to Keep in Mind |
|---|---|---|---|
| Ductwork Repair & Sealing | Leak and gap identification, Disconnected section repair, Duct sealing at supply and return runs, Airflow verification after sealing | Homes with uneven temperatures, weak airflow at certain vents, or energy bills that are higher than expected given the equipment installed | Conditioned air escaping into an unconditioned attic or crawl space before it reaches the living area forces the system to run longer to compensate, which shows up in both comfort and cost. |
| Heat Pump Repair & Installation | Reversing valve and refrigerant check, Defrost cycle inspection, Auxiliary heat verification, Cold-climate performance assessment | Properties with an existing heat pump that is not heating or cooling correctly, or homeowners considering a switch from a split system | Modern cold-climate heat pumps operate efficiently well below freezing, making them a practical year-round option in central Illinois in a way older models were not. |
| Whole-Home Dehumidification & Humidity Control | Whole-home dehumidifier installation, Integration with existing HVAC system, Humidity set point confirmed before sign-off, Reduced load on cooling equipment | Champaign County homeowners dealing with persistent indoor humidity that makes the house feel warmer than the thermostat reads | A whole-home dehumidifier pulls moisture from the air as it circulates through the system, which is more consistent than a portable unit and reduces the strain on the air conditioner during humid stretches. |
| AC Repair & Service | Refrigerant charge check, Capacitor and contactor inspection, Coil and airflow diagnosis, Thermostat signal verification | Homes or buildings where the AC is running but not cooling, or not starting at all | Champaign summers push cooling equipment hard. A system that is marginal in mild weather often falls behind entirely during a stretch of high heat and humidity. |
| Indoor Air Quality & Air Filtration | Filtration upgrade assessment, Air purifier installation, Compatibility check with existing system, Options explained before equipment is recommended | Homes and commercial spaces where dust, allergens, or airborne particles are a recurring concern | The right filtration upgrade depends on what the existing air handler can support. We assess that before recommending equipment so the system is not restricted by a filter it cannot handle. |
| Furnace & AC System Replacement | Combined furnace and central AC replacement, Load calculation for correct equipment sizing, Ductwork connection and thermostat wiring, System startup and communication verified | Champaign homeowners whose furnace or central AC has aged out and needs a matched replacement that handles both heating and cooling demands | A combined furnace-and-AC replacement is the most common high-value HVAC job in this climate. Getting the sizing right matters because an oversized system short-cycles and an undersized one never catches up on the hottest or coldest days. |
| Full System Installation & Replacement | Matched furnace and AC or heat pump selection, Connection to existing ductwork, Thermostat wiring and communication check, Full system startup and sign-off | Homeowners replacing aging or repeatedly failing equipment, or properties upgrading from undersized or mismatched systems | Properly matched equipment sized to the actual load of the space runs more efficiently and holds temperature more consistently than a unit that is too large or too small. |
| Emergency HVAC Service | No-heat and no-cool calls, System-down diagnosis, Priority scheduling for urgent situations, Scope and price confirmed on the call | Households or buildings where the heating or cooling system has stopped working and waiting for a routine appointment is not an option | Emergency calls are answered when you reach out. The scope is confirmed on the call so you know what to expect before anyone arrives. |
| Thermostat & Smart-Control Installation | Smart thermostat setup and wiring, Control signal verification at the air handler, Zone control configuration, System communication confirmed before sign-off | Homeowners upgrading from an older thermostat or troubleshooting short-cycling and temperature complaints traced to the control side | A thermostat that is not communicating correctly with the outdoor unit can cause symptoms that look like equipment failure. Confirming the control signal is the first step. |
| Heating & Furnace Repair | Ignition system check, Heat exchanger inspection, Pressure and limit switch testing, Blower motor and control board diagnosis | Homeowners dealing with a furnace that will not start, runs briefly and shuts off, or blows cold air | Illinois winters can drop below freezing for days at a stretch. A furnace that is short-cycling or struggling to hold temperature is worth looking at before it fails entirely. |
| Seasonal Maintenance & Tune-Ups | Heat exchanger and ignition inspection for furnaces, Refrigerant charge and coil check for AC, Capacitor, contactor, and condensate drain check, Filter and blower motor condition review | Homeowners who want to catch a weak component before the heating or cooling season puts the system under full load | The best time to tune up a furnace is before the first cold snap, and the best time for an AC tune-up is before late spring heat arrives. Scheduling ahead of the season means the work happens before a failure, not after. |
