Why Fireside Heating & Air Co. Is Frankfort’s Preferred Emergency & Commercial HVAC Company
We have been serving homeowners and business owners since 2018, and Frankfort has been part of our territory for decades. Glen Hartman built this company on the principle that a job is only finished when the customer would trust us in their mother’s home. That standard still governs how our technicians work in Frankfort.
Our response time to Frankfort averages under 90 minutes for emergency calls because we keep crews positioned to reach the Clinton County agricultural plain without crossing multiple county lines. We know the local streets, from the narrow alleys behind downtown commercial buildings to the residential blocks between Maish Road and State Road 28.
Frankfort customers choose us because we quote upfront prices and stand behind them with a written 90-Day Done Right Promise. No paperwork, no arguing. If something is not right, we make it right. That is the Keystone Standard applied to heating and cooling.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They are trained to service nine major brands including Carrier, Trane, Lennox, and American Standard, and they understand the specific challenges of Frankfort’s housing stock and climate.
Our Emergency & Commercial HVAC Services in Frankfort
24/7 Emergency HVAC
Emergencies do not wait for business hours, and neither do we. Our phones are answered by a live person every hour of every day, including 2 a.m. on a Sunday when your furnace fails during an Arctic air mass. Frankfort’s flat, open terrain exposes homes to unimpeded wind that drives heat loss calculations well above what nearby cities with tree cover experience. A system that was marginal on a calm night can fail completely when the wind picks up. We carry the parts to repair most systems on the first trip, and we are frank about whether a repair is worth doing versus replacing the unit.
Commercial HVAC
Frankfort’s commercial core includes buildings from the railroad era with tight alley access and modern structures along the commercial corridors. We service both. Our team handles rooftop units, split systems, and packaged equipment for retail, office, and light industrial facilities throughout the 46041 area. We recently swapped a failed rooftop unit on a commercial building in downtown Frankfort, where the narrow alley access forced us to crane the new 10-ton Lennox unit over the roofline. The old unit had its condenser coil clogged solid with corn-husk dust from the harvest season, so we installed a custom filter-minder system to extend service intervals. That is the kind of local knowledge that prevents repeat failures.
Rooftop Unit Service
Rooftop units are common on Frankfort’s commercial buildings, but they are exposed to everything the Indiana sky delivers. Summer heat, winter freeze-thaw cycles, and especially the September-October harvest dust that blows in from surrounding Clinton County cornfields. Standard 1-inch filters that should last 90 days often clog in under 30 days during harvest season. We size replacement filters and maintenance intervals for actual Frankfort conditions, not textbook averages. When a rooftop unit needs replacement, we coordinate crane access for tight downtown locations and schedule around your business hours.
Annual Maintenance
Annual maintenance is not a luxury in Frankfort; it is how you avoid emergency calls. Our $89 Seasonal Tune-Up includes cleaning condenser coils, checking refrigerant levels, testing safety controls, and inspecting heat exchangers for cracks. For commercial customers, we build maintenance schedules around harvest season, pre-positioning filter changes and coil cleanings before the dust hits. Catching a worn blower belt in July beats losing your compressor in January. Maintenance also preserves manufacturer warranties, many of which require documented annual service.

Trusted Brands We Service in Frankfort
We are trained to service all nine major residential and commercial brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our Frankfort-area trucks stock common parts for Carrier, Trane, and Lennox systems, which means faster repairs without waiting for a warehouse shipment. For commercial equipment and less common components, our supplier relationships get us next-day delivery to Clinton County. We do not push one brand over another; we match the equipment to your building, your budget, and how long you plan to stay in it. Glen Hartman has always said that the right system is the one you never have to think about.
Common Emergency & Commercial HVAC Problems We See in Frankfort Homes
- Condenser coils packed with harvest particulate. Every September through October, fine dust from Clinton County corn and soybean fields blows directly into Frankfort. Outdoor condenser coils can clog solid within weeks, triggering high-pressure lockouts that shut down cooling systems entirely. This is predictable, preventable, and specific to agricultural plain communities like Frankfort.
- Original steam-heat risers leaking in Victorian conversions. The streets around downtown Frankfort are lined with homes built during the 1890s-1930s railroad era. Many still have original steam-heat risers that were repurposed for hydronic loops. When those century-old pipes develop leaks, they damage plaster walls and require careful repair by technicians who understand both the old system and the new.
- Undersized ductwork in 1950s ranch homes. Frankfort’s outer edges include mid-century ranch homes with ductwork that was often undersized at installation. Modern high-efficiency furnaces move more air through tighter coils, and the original ductwork cannot handle the static pressure. The result is noisy operation, hot and cold spots, and premature equipment failure.
- Balloon-frame duct retrofits causing wall damage. Frankfort’s balloon-frame homes from the railroad era have plaster-and-lath walls that require specialized sawzall techniques and minimal-vibration duct retrofits. A contractor used to modern stick-frame construction can destroy irreplaceable historic plaster in an afternoon. We have the tools and the patience to do it without that damage.

FAQs - Emergency & Commercial HVAC in Frankfort
Harvest season fills outdoor condenser coils with fine particulate dust that restricts airflow and raises system pressure. In Frankfort, this typically occurs September through October and can reduce a standard filter’s service life from 90 days to under 30. We schedule pre-harvest maintenance visits and can install filter-minder systems on commercial units to alert you before airflow is critically restricted. Call (866) 561-3358 to schedule a coil cleaning before the dust hits.
Yes. We have crained units over downtown Frankfort rooflines where alley access is too narrow for standard boom trucks. We coordinate with local crane operators and secure any required street closures through the city. The key is planning; we survey the site first and build the rigging plan before the old unit comes out. Call (866) 561-3358 to arrange a site evaluation.
No-heat calls from failed ignition systems or cracked heat exchangers in converted gravity furnaces. The original coal or steam equipment in Frankfort’s Victorian and Craftsman homes was replaced decades ago, but the ductwork and venting were often adapted rather than redesigned. We inspect the full system, not just the failed component, to catch safety issues that quick-fix contractors miss. Call (866) 561-3358 for emergency service; estimates are free.
Yes. Our live operators answer commercial emergency calls at the same number, (866) 561-3358, 24 hours a day, every day of the year. We understand that a failed rooftop unit on a Saturday can mean lost inventory or closed doors on Monday. We prioritize commercial calls based on facility type and safety risk, and we carry parts for common commercial brands including Carrier and Trane.
We use specialized sawzall blades with minimal vibration settings and vacuum-assisted cutting to limit plaster damage. Frankfort’s balloon-frame homes require careful routing between studs that are not always on modern spacing. Our technicians have done this work dozens of times in Clinton County historic homes, and we repair any incidental plaster damage before we leave. Call (866) 561-3358 for an in-home assessment and written estimate.
