Most furnaces in Franklin County were sized by rule of thumb, installed by whoever was cheapest, and never looked at again until the night they died. We do it differently. Every furnace installation starts with a load calculation of your actual house — the brick cape in Montrose Park, the two-story in Thornhill with the bonus room, the farmhouse out past Farmdale — because a furnace that's too big short-cycles and wears itself out, while one that's too small loses a race with a Kentucky cold snap.
We install high-AFUE gas furnaces for homes on Frankfort's city gas lines and propane-ready models for rural properties across the northern county. Venting gets engineered, not eyeballed — older chimney-vent systems often need proper liners, and high-efficiency units vent through PVC with condensate management. Add variable-speed blowers for quieter, more even heat and better summer dehumidification, and a properly installed furnace becomes the backbone of a comfortable house for the next twenty years.
Free in-home estimates come with side-by-side options, AFUE-versus-cost comparisons, rebate guidance, and financing choices. Call +1 (327) 210-5999 to book yours — most estimates are scheduled within two business days.
Signals it's time to replace the furnace
Age past 15–20 years
Furnaces in this range are entering failure season. Replacing on your schedule — not at 2 AM in January — costs less and hurries no one.
Cracked heat exchanger
A breached exchanger is a replacement event, full stop. We document it with photos for your records and walk through options calmly.
Rising winter gas bills
An 80% AFUE furnace from 1998 wastes one dollar in five. Modern 95%+ units can cut heating bills enough to matter in our long winters.
Rooms that never warm evenly
Sometimes ducts, sometimes the furnace. Our estimate process measures airflow so the new system actually fixes it.
Repeated board and motor failures
Two significant repairs on an aging furnace is the industry's honest tipping point. We'll tell you when repair stops making sense.
Planning AC replacement too
Pairing furnace and AC replacement unlocks matched-system efficiency and saves double install labor. Ask about bundle pricing.

What a furnace replacement costs in Frankfort
Furnace pricing depends on the equipment tier and what your home needs around the equipment. The honest drivers:
Every estimate is free, in person, and in writing — fixed pricing approved by you before any work begins.
Efficiency (AFUE) level
80% single-stage furnaces are the entry point; 95–97% two-stage and modulating units cost more but trim heating bills every winter for decades.
Venting changes
Switching to high-efficiency PVC venting, or lining an old masonry chimney for a mid-efficiency unit, is often the biggest variable in older Frankfort homes.
Blower and staging
Variable-speed ECM blowers add cost but improve comfort, quiet, and summer humidity removal — a strong pick for two-story homes.
Duct and return-air work
1950s–1970s homes often have undersized returns; fixing them during replacement is far cheaper than fixing an unhappy system later.
Financing and rebates
Approved-credit financing and utility rebates frequently bring a higher-tier furnace into the same monthly budget as the base model.
Proof, Not Promises
Why Frankfort Homeowners Choose Us for Furnace Installation
Sized by calculation, not habit
Every furnace quote starts with a Manual J load calculation. The oversized furnaces short-cycling through half of Frankfort are the legacy of rule-of-thumb sizing — we don't repeat it.
Venting engineered, not eyeballed
High-efficiency PVC venting, masonry chimney liners, combustion air — venting is where older Frankfort homes make or break an install. It's engineered into every proposal.
Two-stage and variable comfort
Variable-speed blowers quiet the house, balance the upstairs, and dehumidify better in summer. We specify them where the home and budget actually benefit.
Commissioned and documented
Gas pressure set, temperature rise verified, safeties tested, warranty registered — you get the startup numbers and the paperwork before we leave.

Frankfort Homeowners on Our Work
"Our 2004 heat pump died in the first July heat wave. They had a tech out same day, gave us three options in writing with real numbers, and the new variable-speed system was running by Friday. The upstairs is cool for the first time since we bought the house."
Sarah M.
Woodlake · Heat Pump Replacement · July 2025
"Furnace quit at 11 PM on a 20-degree night with two kids in the house. A real person answered the phone, coached us through protecting the pipes, and had the ignitor replaced before midnight. Can't ask for more than that."
David R.
South Frankfort · Furnace Repair · January 2025
"I was terrified anyone putting AC in my 1880s rowhouse would destroy the plaster. Their crew threaded everything through existing chases — you honestly cannot find the system. The house stays cool and the historic board never had to hear about it."
Brenda T.

Furnace Installation FAQs
Local answers for Frankfort homes — the questions we hear at kitchen tables across the county.
Yes. City-gas homes get natural gas units; rural properties on tanks need propane-configured units with proper orifices and regulators. Many homes out toward Farmdale and Harvieland run propane, and we set up and commission those systems for the fuel you actually use.
Well-maintained furnaces here commonly reach 18–22 years. Our long heating season and hard freezes are real workload, which is why annual maintenance and proper sizing (no short-cycling) are the two biggest longevity levers.
If your AC is over 10 years old or uses R-22, replacing both together usually costs less than two separate jobs and lets the matched system hit its rated efficiency. We'll show you the paired pricing during the estimate.
Yes — venting engineering is part of our furnace scope, including liners, PVC venting runs, and termination placement per code. It's one of the most important details in older Frankfort homes and one most low-bid installs get wrong.
A straightforward condenser-and-coil swap is typically one day. Add furnace pairing, duct modifications, or crane access for tight downtown lots and it can run two days — you'll know the schedule before we start.
