Sometimes the system itself is fine and one part has given out. A capacitor fails, a pressure switch stops responding, a blower motor draws too much current and trips the board. The repair is specific, the cost is contained, and the rest of the equipment keeps doing its job. Other times the unit has been limping along for years and a repair only delays the conversation that should have happened a season ago. Both calls come in regularly from homes and rental properties in Sullivan, and the approach is the same either way: what is actually there gets looked at before anything is recommended.
We cover heating and cooling work throughout Sullivan and Moultrie County, from single-room ductless installs to full system replacements in older homes that have been on the same equipment for decades. Every call gets the same attention, whatever the job size.

Before a small issue turns into a full breakdown, it helps to understand how pricing works on this kind of call. The rate for the visit is discussed on the phone before anything is scheduled. You know what the call covers before the technician arrives.
What moves the number is what the job turns out to be. A failed capacitor on an otherwise sound air conditioner is a straightforward repair. A refrigerant leak that requires tracing the line set, recovering the charge, and repairing the source is a longer job. A heat exchanger that has cracked on a furnace that is also undersized for the house opens a different conversation entirely. The fault, what has to be reached to fix it, and whether repair or replacement makes more sense for the equipment and the budget are the factors that shape the final price.
None of that is guesswork on the phone. The scope is confirmed before the work begins, and the price is agreed before anything is replaced or installed. Ask what the quote covers and you get a straight answer.
An air conditioner that runs continuously without dropping the temperature is one of the more frustrating problems of a humid Illinois summer. The cause is often refrigerant charge, a dirty evaporator coil, or a condenser that is struggling to reject heat. It can also be an airflow problem in the duct system rather than anything wrong with the equipment itself. The diagnostic visit checks the refrigerant level, the coil condition, the blower performance, and the thermostat signal before a repair path is recommended.
Leaking ducts are a common source of uneven temperatures and higher-than-expected energy bills in older homes. When conditioned air escapes into an unconditioned attic or crawl space before it reaches the living area, the system runs longer to compensate. Duct sealing closes those gaps at the source. We also handle disconnected duct sections and airflow troubleshooting for systems where the equipment tests fine but certain rooms never reach the set temperature.
A burning smell on the first heating call of the season is often dust burning off the heat exchanger and clears quickly. A smell that persists, or one that returns after the system has been running, is worth investigating. Musty odors from the vents usually point to moisture in the duct system or on the evaporator coil. Neither should be ignored, because each can indicate a condition that will get worse under continued load.
A house where one room is always warmer or cooler than the others may have a duct or register problem rather than an equipment failure. Rebalancing involves checking airflow at each supply and return, identifying restrictions or disconnected runs, and adjusting dampers where the system has them. The cause of an uneven house actually investigated is worth more than adjusting the thermostat and hoping the problem evens out.
Whole-home humidity control connects directly to the existing HVAC system. A dehumidifier pulls moisture out of the air independently of the cooling cycle, which matters during the humid stretches of summer when the air conditioner alone cannot keep indoor humidity at a comfortable level. A whole-home humidifier addresses the dry air that comes with extended furnace operation in winter. We install both and confirm the system is set to the correct target level before the job is finished.
A home that was built without central air, or one where the original equipment has reached the end of its useful life, is a straightforward installation candidate. The job involves the outdoor condenser, the air handler or evaporator coil, the refrigerant line set, the low-voltage control wiring at the unit, and the connection to the existing duct system. Sizing the equipment correctly to the space matters as much as the equipment itself. An oversized unit short-cycles and leaves the air feeling damp. An undersized one runs constantly and cannot keep up on the hottest days. You will find the rest of it on our heating and cooling services page.
Sullivan sits in a part of Moultrie County where properties range from in-town homes on standard lots to farmhouses and outbuildings set well back from the road. Access is rarely a problem, but the equipment found on older rural properties sometimes is.
A farmhouse that has been on the same furnace for thirty years may have a unit that has been repaired repeatedly and is now on its last reliable component. Ductwork in older construction was often sized for equipment that no longer exists, and additions built over the years may never have been properly connected to the main system. None of that is unusual, and none of it prevents a diagnosis from being done correctly.
What makes a property straightforward to work on is access to the equipment and a clear description of what it is doing. When you call, describe the symptoms as specifically as you can: which rooms are affected, what the thermostat reads versus what the house feels like, and whether the system is making any sounds it did not make before. That information shapes the visit before anyone arrives.
If a previous repair did not solve the problem, or if you have been told the system needs to be replaced and you want a second look before committing to that cost, call us. The diagnostic visit starts from the equipment, not from what someone else concluded about it.
Taking over work started by someone else is a routine part of what we do. A system that was partially repaired, a thermostat that was replaced without resolving the underlying fault, or a refrigerant charge that was topped off without locating the leak are all situations where a fresh diagnosis makes sense. We explain what we find before recommending anything, and the price for any additional work is confirmed before it is done.
The sooner you call, the sooner your comfort is back. We take calls every day from 5:00 AM to 9:30 PM, including weekends, and emergency no-heat and no-cool calls are handled the same way as any other: the scope is confirmed on the phone and the rate is settled before anyone is dispatched.
For properties where a tenant is in place or a business has to stay open, we work around the schedule that exists rather than asking for a clear calendar. When you call, tell us the constraints and we will confirm what is available. A rental property with a heating failure in January is not a situation that waits for a convenient week.
Seasonal maintenance scheduled around your calendar is also available for homeowners who want the furnace checked before the cold arrives or the air conditioner inspected before summer. The call is where timing and scope are confirmed.
Sullivan is where most of our Moultrie County calls come from, but coverage extends throughout the surrounding area. If you are in Allenville, Bethany, Lovington, Findlay, or Windsor, we serve those communities as well. Calls from the outlying parts of the county are handled the same way as in-town calls: the scope is confirmed on the phone and the rate is agreed before the visit is scheduled.
If you are unsure whether your address falls within the service area, call and ask. Coverage questions are answered on the call before anything is booked.
A diagnostic visit is the right starting point. The technician checks ignition components, heat exchanger condition, airflow, and controls to give you an accurate picture of where the equipment stands. From there, the conversation is about whether a repair addresses what was found or whether replacement makes more sense given the age and condition of the unit. The price for any work is confirmed before anything is done.
In most cases, yes. Whole-home air filtration and air purification equipment connects to the existing air handler and treats air as it circulates through the system. Compatibility depends on the equipment and the duct layout, which we confirm before recommending anything. Call and describe your current setup and we will explain what options are available.
Zoning can be added to many existing systems, though it requires dampers in the ductwork, a zoning control board, and individual thermostats for each zone. Whether your current equipment and duct layout can support zoning is something we assess before recommending it. The call is where we discuss whether it is a practical option for your property.
Humid summers put more sustained load on air conditioning equipment than dry-climate summers do, because the system is working to remove moisture from the air as well as lower the temperature. A unit that is marginal in performance tends to show that limitation more clearly under those conditions. A seasonal inspection before the heat arrives is a practical way to catch a weak component before it fails under peak load.
Diagnosis explained first. Code-compliant work. Clean finish.

Heating and cooling work covers a wide range of jobs, and knowing which service fits your situation makes it easier to get the right call scheduled. We handle everything from a single-component repair to a full system replacement, and the table below lays out what each service covers, who it is best suited for, and a practical note worth knowing before you book. Call for a quote and we will confirm the scope and the price before anything is scheduled.
| Service | Scope of Work | Common Needs | What to Keep in Mind |
|---|---|---|---|
| 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 | Sullivan 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. |
| 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. |
