Why Fireside Heating & Air Co. Is Indianapolis’s Preferred Heating & Furnace Company
Indianapolis homeowners don’t want the cheapest bid. They want the last heating company they’ll ever have to call. We’ve earned that reputation across Marion County by doing what we say we’ll do, then putting it in writing.
Our 90-Day Done Right Promise means if the repair or installation isn’t right, we make it right. No paperwork to file. No arguing with a dispatcher. Just a square deal, honored in writing. That’s the Keystone Standard, applied to heating and cooling in Indianapolis.
Phones are answered by a live person around the clock - including the 2 a.m. no-heat emergency on the coldest night of the year. Our background-checked, uniformed technicians put on shoe covers without being asked and work in your home the way they would in their own mother’s.

Our Heating & Furnace Services in Indianapolis
Furnace Repair
A furnace that won’t start, cycles too often, or blows cold air isn’t just uncomfortable in Indianapolis - it’s dangerous when actual temperatures hit -11°F, like they did in January 2019. Our technicians carry diagnostic equipment and common parts for nine major brands on every truck, so most Indianapolis furnace repairs are completed same-day. We see a lot of failed ignitors in older Carrier and Goodman units, gas valves that stick after humid summers, and blower motors strained by the duct imbalances common in central Indianapolis homes. The price quoted is the price paid. We don’t tack on “discovery fees” after we’re in your basement.
Furnace Replacement
Sometimes repair isn’t the right call. We’ll give you straight talk about repair versus replace, based on the age of your equipment, the cost of the fix, and how many winters it has left. A new furnace installation in Indianapolis runs $3,500-$7,500, depending on size, efficiency rating, and whether your duct system needs correction. Here’s where our local knowledge matters: in Fountain Square, Bates-Hendricks, and the near-Eastside, we regularly find modern furnaces connected to century-old gravity ductwork. The equipment isn’t the problem. The ducts are. We’ll tell you if duct remediation is the smarter spend, and we’ll size your new system for Indianapolis’s full temperature swing - from polar vortex lows to 70°F+ summer dew points.
Furnace Tune-Up
Our $89 seasonal tune-up catches the problems that turn into 2 a.m. emergency calls. In Indianapolis, that means checking heat exchanger integrity after the stress of hard winters, testing gas pressure and combustion, and inspecting condensate drains that can pool acidic water in flat basement lines. We also examine blower belts, ignitor wear, and thermostat calibration. A tune-up takes about an hour. It extends equipment life, keeps efficiency up, and gives you a written report on what we found. No scare tactics. Just facts.
Heat Exchanger Inspection & Replacement
This is the one that keeps us up at night, and it should concern every Indianapolis homeowner with a gas furnace. A cracked heat exchanger can leak carbon monoxide into your home. It’s not always obvious - the furnace may run fine while silently poisoning the air. We inspect heat exchangers with cameras and combustion analyzers on every service call, and we replace them when they fail. In Indianapolis’s older housing stock, we see accelerated corrosion from uninsulated plenums sitting on dirt basement floors, especially after extreme cold events stress the metal. If your heat exchanger is compromised, we’ll show you the crack, explain your options, and never pressure you toward replacement when repair is safe.

Trusted Brands We Service in Indianapolis
We’re trained to service and install all nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock common parts for Carrier, Trane, and Lennox on our Indianapolis trucks, which means faster repairs and fewer return trips. Glen Hartman has relationships with regional distributors going back decades, so when a specialty part is needed for an older American Standard or Bryant unit in a Broad Ripple bungalow, we can usually source it within 24 hours. We don’t push one brand over another. We match the equipment to your home, your duct system, and your budget.
Common Heating & Furnace Problems We See in Indianapolis Homes
- Oversized gravity ducts from coal-era conversions. In Fountain Square and Bates-Hendricks, we regularly find modern 80,000 BTU furnaces teed into 24-inch round gravity trunks. The homeowner has three rooms that never heat right, blames the new furnace, and the real fix is duct remediation - not equipment replacement.
- Heat exchanger corrosion from uninsulated basement plenums. Pre-WWII Indianapolis homes often have sheet-metal plenums sitting directly on dirt or original concrete floors. The moisture accelerates rust, and polar vortex lows like January 2019’s -11°F stress the metal further. We catch this with camera inspection before it becomes a safety issue.
- Condensate pooling in flat drain lines. High-efficiency condensing furnaces produce acidic water that needs to drain properly. In older Indianapolis homes with basement floor drains that lack proper pitch, this condensate pools and backs up, destroying the secondary heat exchanger. We correct the drain line, not just replace the part.
- Short-cycling from duct imbalance or oversized equipment. A furnace that starts and stops constantly wastes fuel, wears components prematurely, and never delivers even heat. In Indianapolis’s converted gravity-duct homes, this is almost always an airflow problem, not a thermostat problem.

What moves the needle within these ranges? Parts versus labor, accessibility (tight basements in older Indianapolis homes take longer), and whether duct correction is needed alongside the furnace work.

FAQs - Heating & Furnace in Indianapolis
No - the furnace is probably fine, but your ducts are not. In Indianapolis’s central ZIP codes, pre-WWII bungalows were built with coal-fired gravity “octopus” furnaces and oversized trunk lines that were never properly resized for gas forced-air. We’ve tackled this exact scenario in Fountain Square: a 1940 bungalow with a 24-inch gravity trunk feeding a modern 80,000 BTU Goodman furnace. The homeowner reported three rooms that stayed cold despite the furnace running fine. We isolated the oversized duct, installed a properly sized supply trunk, and rebalanced the runs - the temperatures evened out without replacing the furnace. Call (866) 561-3358 for a free duct assessment.
Short-cycling in Bates-Hendricks is almost always an airflow imbalance, not a thermostat or equipment defect. The neighborhood’s converted gravity-duct homes create excessive static pressure or bypass airflow that tricks the high-limit switch into shutting down the burner. We measure static pressure, inspect the duct layout, and correct the imbalance. Sometimes it’s a simple filter change. Often it’s duct remediation. We’ll tell you which before we start any work. Call (866) 561-3358 - estimates are free.
A heat pump can work in Indianapolis, but only if sized and installed with backup heat adequate for our extremes. The January 2019 polar vortex brought actual temperatures to -11°F, which will overwhelm a standard heat pump’s capacity. We install dual-fuel systems or properly sized electric backup for Indianapolis homes, and we never recommend a heat pump as the sole heat source without that safeguard. The right system, correctly sized for our temperature range, is efficient and reliable. The wrong system leaves you cold when it matters most. Call (866) 561-3358 and we’ll walk through what makes sense for your home.
Rust on the plenum doesn’t automatically mean you need a new furnace, but it does mean you need inspection. In Indianapolis’s older homes, uninsulated sheet-metal plenums sitting on dirt basement floors corrode faster than in newer construction. The real concern is whether that corrosion has reached the heat exchanger, which is a safety issue. We inspect with cameras and combustion analyzers. If the heat exchanger is sound, we may recommend plenum replacement or coating, plus correction of the moisture source. If it’s cracked, replacement is the only safe option. We’ll show you what we find and explain your options. Call (866) 561-3358.
We install and service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard throughout Fountain Square and all Indianapolis neighborhoods. We don’t push one brand. We size the equipment to your home’s heat loss, your duct capacity, and your budget. In Fountain Square’s older homes, that often means correcting ductwork first, then matching a properly sized furnace to the corrected system. We stock parts for Carrier, Trane, and Lennox on our trucks for fastest service. Call (866) 561-3358 for a free estimate.
