Some customers call once, get the problem fixed, and move on. Others call every spring and fall, keep their equipment on a maintenance schedule, and reach out the moment something sounds off. We work with both in Lewisburg. A town this size has a mix of older homes where the original equipment is still running, newer builds that have never had a proper tune-up, and rental properties where a landlord needs the system back up before a tenant loses heat. Whatever the situation, the job starts the same way: a call, a scope, and a price before anyone is scheduled.
We cover heating and cooling for homes and commercial properties across Marshall County. We handle the full range of work, from a single repair call to a matched furnace and air conditioner replacement.
If you are in Lewisburg and need the system looked at, call (615) 825-9295. We are available every day from 7:30 AM to 9:00 PM.
Before calling for a repair, a few minutes at the property can save time and sometimes settle the question entirely. Start at the thermostat. Check that it is set to the right mode, that the temperature setting is where you expect it, and that the display is on. A dead thermostat battery or a tripped mode switch accounts for more no-heat and no-cool calls than most people expect.
Next, check the filter. A filter that has not been changed in several months can restrict airflow enough to cause the system to run without satisfying the thermostat, or to shut itself down on a safety limit. Pull it out and hold it to the light. If you cannot see through it, replace it before calling. Check the supply switch on the air handler or furnace, which looks like a standard light switch and gets bumped off accidentally more often than it should. If the circuit breaker for the unit has tripped, reset it once and see whether it holds.
None of this replaces a diagnostic visit when the system has a real fault. But the symptoms you describe on the phone shape what gets brought out, and a clear description of what you already checked makes the call more useful for everyone.
Ductless mini-split systems handle heating and cooling in spaces where running ductwork is impractical or not worth the cost. A garage converted to a workshop, a sunroom added after the original system was sized, a home office above a detached structure, or a room at the end of a long duct run that never quite reaches temperature are all situations where a mini-split solves the problem cleanly.
A single-zone mini-split pairs one outdoor unit with one indoor head. It handles one room or one defined space, and it does so independently of whatever the central system is doing. A multi-zone setup runs two or more indoor heads from a single outdoor unit, which makes sense when several spaces need independent control or when a central system is not the right fit for the whole building.
On the commercial side, a small office, a server room, or a retail space with a heat load that the main system cannot manage are all candidates for a ductless installation. The indoor head mounts high on the wall, the refrigerant line runs to the outdoor unit, and the space gets its own thermostat independent of the rest of the building. We handle mini-split installation, repair, and replacement for both residential and commercial properties across the area.
A no-heat call in January and a no-cool call in July are both situations that need to move quickly. We take emergency calls every day from 7:30 AM to 9:00 PM. When you call, someone who knows the trade picks up and can talk through the symptoms before anything is scheduled. The scope and the price are settled on the call.
For rental properties, the pressure is different. A tenant without heat or cooling is a landlord problem that compounds quickly, and we understand that the timeline matters. For businesses that have to stay open, we work around operating hours where the job allows it. The visit is scheduled with the property's situation in mind, not just the equipment's.
If the system has completely stopped and you are not sure whether it is a repair or a replacement, that question gets answered once the system is diagnosed, not before. We will confirm the repair with you before it goes ahead, and if replacement is the better answer, you will hear that on the same visit.
When an air conditioner will not start at all, the diagnostic begins with the controls, the disconnect at the outdoor unit, and the capacitor that starts the compressor and fan motor. A failed capacitor is one of the more common causes of a unit that hums but will not run, or one that simply does nothing when the thermostat calls for cooling. Refrigerant level and airflow through the coil are checked as part of the same visit, because a system that has been struggling before it stopped may have more than one contributing fault.
A furnace that will not fire often comes down to the ignition system. A failed igniter, a dirty flame sensor, or a pressure switch fault will each prevent the burner from lighting, and each produces a system that attempts to start, fails, and locks out. The diagnostic covers the ignition sequence, the heat exchanger, the blower, and the controls. If the furnace is an older unit and the repair cost is significant, we will talk through whether a replacement makes more sense before any work is authorized.
A system that runs without reaching the set temperature is telling you something specific. The most common causes are a low refrigerant charge, a dirty coil restricting heat transfer, or ductwork that is losing conditioned air before it reaches the rooms. Oversizing and undersizing both produce similar symptoms, which is why the diagnostic checks refrigerant, airflow, and controls before a conclusion is reached. HVAC work like this is the bulk of what a season brings, and getting the diagnosis right matters more than getting to a repair quickly.
When a room is added to a home, the existing duct system is rarely sized to handle it. The result is a space that the central system cannot reach effectively, and a house where the rest of the rooms perform worse because the system is working harder to compensate. A ductwork design for an addition starts with the existing system's capacity and the load the new space adds. The solution may be extending the existing duct, adding a dedicated branch, or recommending a ductless unit for the new space if the central system does not have the capacity to absorb it. Plenty of Lewisburg jobs start with a look at the page that lists our HVAC services.
Pricing is based on what the job actually requires, and that is not fully known until the system has been diagnosed. A repair call for a failed igniter costs differently from a refrigerant leak that requires locating the leak, recovering the charge, making the repair, and recharging the system. A full system replacement depends on the equipment selected, the conditions at the property, and what the installation involves.
When you call, you get a range for common repairs and a firm quote for straightforward work. For larger jobs, the quote is given after the system is assessed. The price is confirmed before any work is scheduled, and if the diagnosis changes the scope, that conversation happens before the work does.
What moves a quote in either direction: the fault itself, how accessible the components are, whether parts need to be sourced, and whether a repair is the right answer or a replacement is the better use of the money. Staying ahead of HVAC problems keeps your home comfortable and often keeps the cost lower, which is why a seasonal tune-up is worth scheduling before the peak of summer or the start of heating season.

Residential HVAC. Commercial HVAC. One number for both.
The right answer depends on the existing system, the home's ductwork, and what the heating load looks like over a typical winter. The region's climate sits in the zone where heat pumps perform well through most of the heating season, and Tennessee has among the highest heat-pump adoption rates in the country. A gas furnace is still the right choice in some situations, and the call is the place to talk through which one fits your property and your usage.
Equipment documentation, registration information, and any paperwork related to the installation itself are part of what gets handed over when the job is complete. The specifics depend on the equipment, and we can go over what to expect on the call.
A duct inspection traces the supply and return runs for gaps, separations, collapsed sections, and areas where connections have come loose. In some cases, pressure testing helps identify leakage that is not visible by inspection alone. The findings determine what sealing or repair work is needed.
Yes, significantly. A system installed with the correct refrigerant charge, proper airflow settings, and accurate electrical connections runs as the manufacturer designed it to. A system installed incorrectly works harder than it should from day one, which shortens the life of the compressor and other components.
Call (615) 825-9295 during our hours of 7:30 AM to 9:00 PM and describe the system and the symptom.
We can scope the job on the phone and confirm a price before the visit is booked, which means you have the information you need before anyone goes out to the property. Emergency no-heat and no-cool calls are treated as priority work, and we can discuss access arrangements for properties where you will not be on site.
The question most people want answered before they commit to anything is whether the repair makes sense or whether the money is better spent on a replacement. That is a reasonable question, and it deserves a direct answer based on the actual condition of the system, not a guess made over the phone.

We cover the full range of heating and cooling work for homes and businesses across Lewisburg and Marshall County. The table below lays out what each service includes, who it fits best, and a practical note worth knowing before you call. Every job starts with a diagnosis, and you get the price before anything is scheduled.
| HVAC Service | What the Service Includes | Common Needs | Things to Know |
|---|---|---|---|
| AC Repair & Service | Refrigerant charge check, Condenser and evaporator coil inspection, Blower and airflow diagnosis, Controls and thermostat verified | Homes or businesses with an AC that won't cool or is running constantly | A dirty evaporator coil and a low refrigerant charge produce nearly identical symptoms, so both get checked before a repair is quoted. |
| Full System Installation & Replacement | Equipment sizing for the space, Removal of existing system, Installation of new heating and cooling equipment, Controls and airflow verified at completion | Homes or commercial properties where repair costs outweigh what the equipment is worth | Getting the sizing right affects both comfort and long-term operating cost. An oversized or undersized system creates problems the equipment itself cannot fix. |
| Ductwork Repair & Sealing | Leak location across supply and return runs, Connection sealing and duct repair, Airflow measured at registers, Attic and crawlspace duct sections addressed | Homes with weak airflow, uneven temperatures, or high energy bills despite a working system | Leaking ducts can send a significant share of conditioned air into attics and crawlspaces. The system runs longer to compensate, which shows up on the energy bill. |
