Why Frankfort Homeowners Choose Fireside Heating & Air Co.
We’ve learned that Frankfort homeowners don’t want to become HVAC experts. They want a company that shows up when promised, quotes a price that doesn’t budge, and stands behind the work without making them fill out forms or argue on the phone.
Fireside has built that reputation here since 2018. Our reviews from Frankfort customers consistently mention the same things: the technician who arrived at 11 p.m. on a Sunday when the furnace quit, the upfront price that matched the final bill, the call back to make sure everything was still running right. We serve neighborhoods throughout the city, from the Victorian homes along South Main Street to the ranch houses near T.P.A. Park and our Shelbyville service area.
Our technicians are background-checked, uniformed, and trained as journeymen. They put on shoe covers without being asked. They carry parts for nine major brands, including Rheem, York, and Bryant, so most repairs don’t require a return trip. Every job is backed by our 90-Day Done Right Promise: if it’s not right, we make it right, in writing, with no paperwork and no arguing. That’s the Keystone Standard, applied to heating and cooling.
And when you call (866) 561-3358, a live person answers. Nights, weekends, holidays. No voicemail tree. No callback tomorrow.
HVAC Services We Offer in Frankfort
AC Repair & Installation
Frankfort summers regularly push past 90°F with humidity that makes the air feel heavier still. When your air conditioner fails or struggles to keep up, we diagnose the problem directly and quote the repair cost before any work begins. Our trucks carry components for Carrier, Trane, Lennox, and other major brands so we can often restore cooling the same day. Learn more about our AC Repair & Installation in Frankfort.
Heating & Furnace Service
With Arctic air masses sweeping across the open Clinton County plain, Frankfort winters deliver wind chills well below 0°F. That kind of cold finds every weakness in a heating system. We repair gas furnaces, electric heat systems, and the legacy equipment still found in many older homes, always with upfront pricing and our 90-Day Done Right Promise. Learn more about our Heating & Furnace in Frankfort.
Heat Pump & Mini Split Systems
Heat pumps and ductless mini-splits offer efficient heating and cooling in one system, and they’re particularly well-suited to Frankfort’s variable climate and to homes where running ductwork through plaster walls isn’t practical. We size these systems carefully for the full temperature range, from sub-zero winter nights to humid summer afternoons. Learn more about our Heat Pump & Mini Split in Frankfort.
Air Quality & Ventilation
Frankfort’s fall harvest season brings a specific challenge: fine particulate from surrounding corn and soybean fields that overwhelms standard filters and packs outdoor coils within weeks. We install whole-home air purifiers, humidifiers, and Air Quality & Ventilation in Frankfort solutions sized for agricultural-plain conditions, not suburban assumptions.
Emergency & Commercial HVAC
When the heat goes out at 2 a.m. or your commercial system fails before opening, our Frankfort Emergency & Commercial HVAC team answers the phone with a live person and dispatches a technician who treats your home or business with the same care they’d give their mother’s. No after-hours fees hidden in the fine print. The price quoted is the price paid.

Why Frankfort’s Climate & Housing Affect HVAC
Frankfort’s identity as the historic “Hub City” railroad boomtown shaped a residential core dominated by late-1800s to early-1900s balloon-frame homes originally heated by coal gravity furnaces or steam radiators. A high share of our HVAC calls here involve full duct-system retrofits through plaster walls rather than straightforward equipment replacements. Homeowners on streets like South Main and near the old depot district know this reality: the beautiful original millwork and high ceilings come with heating systems that were never designed for forced air.
The city’s position in the open Clinton County agricultural plain creates another challenge no urban contractor faces. Every outdoor unit here is exposed to seasonal waves of corn and soybean harvest dust that foul condenser coils and shorten filter life dramatically. We’ve measured it: a standard 1-inch filter that lasts 90 days in tree-shaded Indianapolis needs replacement in under 30 days during Frankfort’s September-October harvest surge. Outdoor coils can pack solid within weeks. Experienced contractors here know to schedule maintenance crews in advance for this predictable surge. The flat terrain also offers no topographic windbreak, so unimpeded Arctic air masses push heat-loss calculations beyond what nearby cities with more varied terrain experience. Systems must be sized for genuine extremes, not averages.
The outer edges of Frankfort add mid-century ranch homes from the 1950s-1970s, many with aging ductwork that was undersized at installation and has only degraded further. Whether we’re working on a Victorian near downtown or a ranch toward the city limits, we size and design for the actual house, not a formula.

FAQs About HVAC in Frankfort
A new furnace installed in a typical Frankfort home generally runs between $4,500 and $7,500, depending on the home’s size, the efficiency rating you choose, and whether duct modifications are needed for older homes with original gravity or steam systems. Homes in the downtown Victorian district often require additional work to route forced air through existing plaster walls. We provide upfront pricing after a thorough in-home assessment, and our free second opinion guarantee means you can compare our written estimate against any other with confidence. Call (866) 561-3358 to schedule.
Fall harvest dust from Clinton County’s corn and soybean fields is the culprit. Fine particulate blows directly into Frankfort from September through October, clogging outdoor condenser coils and overwhelming standard 1-inch filters in as little as two to three weeks. This is a local pattern we anticipate and prepare for. We recommend checking your filter monthly during harvest season and scheduling a coil cleaning if you notice reduced airflow or longer cooling cycles. Our $89 seasonal tune-up includes coil inspection and cleaning. Call (866) 561-3358 to book before the dust hits.
Repair usually makes sense if the fix is under $500 and the furnace is under 12 years old. Replacement becomes the better value when repair costs exceed $1,000, the unit is over 15 years old, or you’re facing repeated breakdowns. In Frankfort’s older homes, we also weigh whether the existing system can actually deliver adequate heat against modern efficiency standards and the 90-Day Done Right Promise we apply to every job. We’ll give you straight talk about repair versus replace, not a sales pitch. Call (866) 561-3358 and we’ll walk through your specific situation.
Yes, for most Frankfort repair calls we offer same-day service, and our trucks carry parts for all nine major brands including Daikin, Bryant, and Rheem. During peak cold snaps, calls come in fast, but we prioritize no-heat emergencies and answer every call with a live person who can tell you exactly where you stand in the queue. We’ve had technicians on South Main Street at midnight and at homes near T.P.A. Park before dawn. Call (866) 561-3358 and we’ll get you scheduled.
We service legacy gravity and steam systems when repair is practical and safe, and we’ve done so for many homeowners in Frankfort’s historic core. That said, these systems are often past their designed lifespan and were built for coal, not modern fuel. When replacement makes more sense, we specialize in forced-air retrofits through existing plaster walls, preserving original millwork and architectural features wherever possible. We’ll inspect your system and give you an honest assessment of repair viability versus conversion. Call (866) 561-3358 for a free evaluation.

What Frankfort Customers Say
"Ductwork in the attic had a disconnected run dumping cold air into the insulation. He found it, resealed it, and a bedroom that was always hot is normal now."
- Hector Guzman"Two other companies told me I needed a whole new system. He put gauges on it, found a leak at a fitting on the line set, repaired and recharged it. That was over a year ago and it is still holding."
- Christine Kim"The thermostat had been miswired by whoever installed it, so the heat strips were running with the AC. He found it in a few minutes and probably saved me a fortune on the next few bills."
- Nicole Fletcher
