We’ve been driving to Franklin since 2018. That’s forty-two winters of navigating county roads when the wind’s howling off Johnson County’s open fields, of pulling into driveways off Jefferson Street at 2 a.m. because the furnace quit, of knowing which subdivisions have the builder-grade Goodmans and Rheems that are finally giving out after twenty-five years. We’re not guessing at your system. We’ve already worked on its neighbors.
When you call (866) 561-3358, a live person answers. Every time. Nights, weekends, holidays. No voicemail tree. We give you a price before we start, and that’s the price you pay. Our 90-Day Done Right Promise means if something isn’t right, we make it right - in writing, no paperwork, no arguing.
Why Fireside Heating & Air Co. Is Franklin’s Preferred Heating & Furnace Company
Our reputation in Franklin was built one house at a time. Homeowners here talk to each other - at the courthouse, at Franklin College events, at the hardware store on Jefferson Street. They remember who showed up when they said they would and who didn’t.
We regularly hear from customers who found us through a neighbor in the 46131 zip code. They mention the same things: our technician put on shoe covers without being asked, explained the repair in plain English, and left the basement cleaner than he found it. These aren’t reviews we wrote ourselves. They’re the reason we’ve stayed busy in Johnson County for four decades.
Response time matters in Franklin. From our dispatch, we’re typically at your door within the hour for emergency calls. We know the difference between downtown Franklin’s narrow streets near the college and the longer county-road drives south and east of town. That local knowledge means we bring the right equipment and parts the first time. Most jobs finish in a single visit.
What sets us apart from the franchise trucks and the fly-by-nights is simple: we answer the phone at 2 a.m., we quote a price we stand behind, and we back it in writing for ninety days. Glen Hartman built this company on the K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it - and we still operate that way.
Our Heating & Furnace Services in Franklin
Furnace Repair
Furnace repair in Franklin runs $150-$700 depending on the part and the hour. We see a lot of ignitor failures in late fall when systems first fire up after months of sitting idle. Gas valve issues are common too, especially in rural properties where propane orifice plugging from moisture or sulfur in the tank causes inconsistent ignition. We carry replacement ignitors, gas valves, and control boards for Carrier, Trane, Lennox, Rheem, York, Daikin, Bryant, Goodman, and American Standard - so we don’t leave your house to go hunt parts.

Furnace Replacement
Full furnace replacement in Franklin costs $3,500-$7,500 installed. This is where our one-trip, heavy-duty approach matters most. We replaced a 22-year-old builder-grade Goodman gas furnace in a 1990s subdivision home near the Johnson County courthouse. The original ductwork was undersized for a high-efficiency model, so we performed a Manual J load calculation and upsized the supply trunk, restoring even heat and eliminating cold spots. That’s the difference between a swap and a proper installation. We size it right, or we don’t do it.

Furnace Tune-Up
Our $89 seasonal tune-up catches the problems that turn into 2 a.m. emergency calls. In Franklin’s climate, we pay special attention to heat exchanger integrity - those polar vortex intrusions that push overnight lows to -5°F stress every component. We clean burners, check flame sensors, test safety limits, and measure gas pressure. For the 1990s-2000s subdivisions off Jefferson Street, this tune-up often reveals the first signs of heat exchanger fatigue in those builder-grade units.

Heat Exchanger Inspection & Replacement
Heat exchanger cracks are a serious safety issue we see frequently in Franklin’s late-1990s builder-grade furnaces, particularly the Goodman and Rheem models in subdivisions off Jefferson Street. Oversizing and short-cycling cause metal fatigue that shows up as cracks - and cracks mean carbon monoxide risk. We inspect with visual and camera methods, and if replacement is needed, we quote it upfront. No scare tactics. Just straight talk about repair versus replace.

Gas Valve Repair
Gas valve problems in Franklin split two ways. In town, it’s usually natural gas pressure regulation or valve coil failure. In rural properties south and east of the city limits, propane presents a different challenge - orifice plugging from tank moisture or sulfur compounds causes intermittent ignition that mimics a failing valve. Our technicians know the difference and carry both natural gas and propane orifice kits. We don’t guess. We test, identify, and fix.

Trusted Brands We Service in Franklin
We train our technicians as journeymen on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Franklin, we stock common parts for Rheem, York, Daikin, and Bryant locally - that means faster turnaround on repairs and fewer return trips. For rural properties running propane, we keep conversion orifices and pressure regulators on the truck. The builder-grade furnaces in those 1990s subdivisions are mostly Goodman and Rheem, so we know those units inside and out. When we quote a repair, we know whether the part is on our shelf or needs ordering - and we tell you upfront.
Common Heating & Furnace Problems We See in Franklin Homes
- Propane orifice plugging in rural county-road properties. South and east of Franklin’s city gas mains, homes run on propane tanks. Moisture and sulfur in the fuel plug orifices and foul ignitors, causing the furnace to light intermittently or not at all. This isn’t a failing furnace - it’s a fuel-system issue that suburban techs often misdiagnose.
- Heat exchanger cracks in late-1990s builder-grade units. The subdivisions off Jefferson Street and near the courthouse are full of Goodman and Rheem furnaces that were oversized for the ductwork. Short-cycling heated and cooled the metal too fast, too often. Twenty-five years later, we’re finding cracks that require replacement.
- Airflow imbalance in pre-WWII gravity conversions. The homes near Franklin College with original gravity or steam systems were converted to forced-air decades ago - often with retrofitted ductwork too small for the load. The result is cold spots, hot rooms, and furnaces that run constantly without satisfying the thermostat.
- Auxiliary heat lockout during polar vortex events. When Johnson County’s flat terrain lets winter winds drive temperatures to -5°F, heat pumps without properly sized auxiliary heat strips can’t keep up. We see this in homes where the original installer sized for average winter, not the extremes Franklin gets every few years.

FAQs - Heating & Furnace in Franklin
Most were builder-grade Goodman or Rheem units installed during the 1990s-2000s construction boom, and many were oversized for the ductwork. Oversizing causes short-cycling - the furnace heats the house too fast, shuts off, restarts, and repeats. That thermal stress cracks heat exchangers and burns out components long before their design life. In Franklin, we’ve replaced dozens of these units in subdivisions off Jefferson Street where the original installer prioritized speed over proper load calculation. If your furnace is hitting twenty years and cycling on and off every few minutes, it’s worth having us inspect the heat exchanger. Call (866) 561-3358 for a free estimate.
Yes. We regularly work with propane systems on rural parcels south and east of Franklin’s city gas mains. Propane furnace replacement requires re-orificing the burner assembly for propane’s different pressure and BTU content, or converting to an electric heat pump if the homeowner prefers. We carry propane orifices and regulators on our trucks, and our technicians understand the fuel-source conversation that suburban-only techs rarely navigate. The key is proper sizing for propane’s characteristics and ensuring the tank and regulator are in good condition. Call (866) 561-3358 and we’ll walk through your specific setup.
Yes, though it’s more involved than a standard replacement. Many pre-WWII homes near Franklin College were converted from gravity or steam to forced-air decades ago, often with retrofitted ductwork that’s undersized for modern high-efficiency furnaces. We start with a Manual J load calculation, then assess whether the existing ductwork can handle the airflow or needs upsizing. In some cases, we can modify the trunk and branch layout. In others, a ductless mini-split might be a better solution for second-floor rooms. We’ve done both in Franklin’s historic core. Call (866) 561-3358 and we’ll inspect your system and give you straight talk about repair versus replace.
Johnson County’s flat, open terrain offers little wind buffering, so when polar vortex intrusions push overnight lows to -5°F to 0°F, heat pumps without adequate auxiliary heat strips can’t maintain setpoint. We size auxiliary heat for the extremes, not the averages. If you’re considering a heat pump for your Franklin home, we’ll run the load calculation against both typical winter conditions and the coldest nights. Undersized auxiliary heat means cold rooms and emergency calls at 2 a.m. We don’t let that happen. Call (866) 561-3358 to review your current or planned system.
Yes - especially at $89, and especially if the furnace is a 1990s-2000s builder-grade unit. At fifteen years, these systems are entering their final reliable phase. A tune-up lets us inspect the heat exchanger for cracks, test gas pressure, clean the burners, and identify whether you’re facing a $200 repair or a $5,000 replacement in the next two years. That information helps you plan rather than panic. Many Franklin homeowners use the tune-up as a decision point: fix what’s needed now, or budget for replacement before the next polar vortex hits. Call (866) 561-3358 to schedule - estimates are free, and seniors and veterans save 5%.
