Fast, Reliable Heating & Furnace Across Carmel
Most furnace repairs in Carmel run $150-$700, and we typically arrive same-day when you call before noon.

We’ve been taking calls at 2 a.m. for over 42 years. A live person answers every time, including holidays. Glen Hartman built Fireside Heating & Air Co. on the idea that you should never have to argue about a repair or wonder if the technician will show up.

Why Fireside Heating & Air Co. Is Carmel’s Preferred Heating & Furnace Company
Carmel’s 2000s building boom created a unique problem most contractors don’t talk about honestly. Production builders installed minimum-code, single-speed or low-tier two-stage furnaces in homes pushing 4,000, 5,000, even 6,000 square feet. Those systems weren’t sized for the finished basements and three-car garages homeowners added later. We see this pattern constantly in Brookshire and Village of WestClay, and we know how to fix it without selling you equipment you don’t need.
Our 90-Day Done Right Promise means if anything isn’t right, we make it right in writing. No paperwork, no arguing. That’s the Keystone Standard Glen Hartman established in 1984, and it hasn’t changed. Our technicians are background-checked, uniformed, trained as journeymen, and they put on shoe covers without being asked. The price we quote is the price you pay. Full stop.
We answer the phone live, 24 hours a day, 7 days a week. Nights, weekends, holidays. When your furnace quits on a single-digit January night in Hamilton County, you’ll talk to a person who can dispatch help, not a voicemail tree telling you to call back Monday.
Our Heating & Furnace Services in Carmel
Furnace Repair
Carmel’s flat, open terrain leaves homes fully exposed to Indiana’s continental extremes. Summer heat indexes exceed 100°F. Winter lows hit single digits or below. This dual-extreme cycle pushes compressors and heat exchangers past their limits, especially in the borderline-undersized systems common to 2000s production builds. We repair all nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Most repairs finish in one visit because our trucks carry the parts that fail most often on builder-grade equipment.
Common Carmel repairs: heat exchanger cracks from high-heat cycling, weak gas valves in short-cycling single-speed units, ignitor failures from improperly sized ductwork in open-plan great rooms. If your repair exceeds $250, we automatically apply $50 off. Estimates are free.
Furnace Replacement
This is where Carmel homeowners need straight talk. That 80% AFUE furnace your builder installed in 2007 wasn’t adequate when new, and it’s certainly not adequate now. In a Village of WestClay colonial, we replaced a builder-installed 80% AFUE single-speed furnace that had been struggling to heat the finished basement since the homeowner added it in 2008. We installed a properly load-calculated two-stage Carrier Infinity with a variable-speed blower and upgraded the zoning to handle the split-level layout. The homeowner reported their energy bill dropped 18% and the basement is finally comfortable.
We don’t do straight swaps. Every replacement starts with a Manual J load calculation to account for your actual conditioned square footage, including that basement finish and the three-car garage workspace you insulated. We size for reality, not the original builder’s spec sheet.
Furnace Tune-Up
Our $89 seasonal tune-up catches the problems that kill furnaces in Carmel’s climate. We inspect heat exchangers for cracks that could leak carbon monoxide, test gas pressure and combustion, check blower amp draw, and verify your thermostat’s staging logic. For homes with integrated whole-home humidifiers, media air cleaners, or ERVs, we service those factory-installed components too. They’re part of your system, not afterthoughts.
Tune-ups in fall prevent the no-heat calls we get every January when neglected systems finally quit. Senior and veteran homeowners receive 5% off, always.
Heat Exchanger Inspection & Replacement
Heat exchanger cracks are the repair we never downplay. In Carmel’s oversized homes with undersized furnaces, the constant high-heat cycling accelerates metal fatigue. A cracked exchanger can cause flame roll-out and carbon monoxide intrusion. If we find a crack, we show you. We explain your options. We don’t pressure. We do document everything in writing, and we won’t let a dangerous system keep running.

Trusted Brands We Service in Carmel
We carry parts and complete systems for Rheem, York, Daikin, and Bryant, plus the full lineup of nine major brands. Our trucks are stocked for the components that fail most on Carmel’s builder-grade inventory: ignitors for single-speed furnaces, gas valves for short-cycling units, variable-speed blowers for proper upgrades. Most jobs complete in one visit because we don’t believe in making you wait while we order parts.
Common Heating & Furnace Problems We See in Carmel Homes
- Heat exchanger cracks from basement finishing overload. Your builder’s furnace was sized for the original footprint. That finished basement added 1,000+ square feet of load. The furnace runs longer, hotter cycles. Metal fatigues faster. We inspect every exchanger with a camera, and we replace with properly sized equipment when needed.
- Cold upstairs bedrooms in two-story colonials. Village of WestClay and Brookshire homes often have open-plan great rooms with massive volume and ductwork that never balanced properly. The main floor overheats. The upstairs freezes. Zoning fixes this. So does variable-speed equipment that runs longer, gentler cycles.
- Ignitor and gas valve failures from short-cycling. Single-speed furnaces in oversized homes hit temperature quickly, shut off, restart quickly. The thermal shock kills ignition components prematurely. We see this weekly in 2005-2012 builds.
- Whole-home humidifier and ERV failures neglected during service. These integrated components were factory-installed on many Carmel homes. They’re part of your comfort system, and they fail too. We service them as standard, not extras.

FAQs - Heating & Furnace in Carmel
Yes, if it’s an 80% AFUE single-speed unit heating more than its original design square footage. These systems are now in the 15-20 year replacement window, and Carmel’s dual-extreme climate accelerates wear. Replacing before failure lets you plan the load calculation and zoning improvements a straight emergency swap won’t include. Call (866) 561-3358 for a free assessment of your actual conditioned load.
Your ductwork was never balanced for the home’s actual volume, and your single-speed furnace cycles too briefly to push air consistently to second-floor runs. We fix this with zoning modifications or variable-speed equipment that runs longer, gentler cycles. Many Village of WestClay homeowners see immediate improvement. Call (866) 561-3358 and we’ll diagnose your specific airflow pattern.
Yes, the City of Carmel requires a permit for furnace replacement. We pull permits on every job and schedule the required inspection. You don’t handle the paperwork. That’s included in our standard process, not billed extra. Call (866) 561-3358 and we’ll walk you through the timeline.
Properly sized, well-maintained furnaces last 15-20 years in Carmel. Undersized builder-grade units stressed by finished basement additions often fail at 12-15 years. The difference is load matching and annual maintenance. Our $89 tune-up extends life and catches the cracks and valve weaknesses that kill systems early. Call (866) 561-3358 to schedule.
Yes, we service propane-fired furnaces throughout Hamilton County. The ignition and heat exchanger components are similar, though gas pressure settings and orifice sizing differ. Our technicians are trained on both fuel types and carry the conversion and testing equipment needed. Call (866) 561-3358 for a free estimate.
