Heating and AC replacement and repair in Danville (40422)
Danville has some of the oldest houses in Kentucky and plenty of newer ones too, and choosing new heating and cooling equipment here means sizing it for the house you actually have, not the one on a spec sheet.
Short answer: HVAC service in Danville
We replace and repair furnaces, heat pumps and central air across Danville and the 40422 ZIP. Danville sits about 36 miles southwest of Lexington, reached by US 27 and KY 34. Atmos Energy supplies natural gas in the city, and Kentucky Utilities and Inter-County Energy supply power. Every replacement starts with a room-by-room load calculation and a duct inspection before we quote equipment.
Why Danville's historic districts change the equipment choice
Danville has ten historic districts on the National Register, from Constitution Square, where Kentucky's first constitution was signed, to the East Main Street district, where Queen Anne, Classical Revival and American Foursquare houses date from 1890 to 1930. Others line Lexington Avenue, Broadway and Maple Avenue. Most of these houses were built with fireplaces or boilers, and the forced air came much later.
That history shapes every replacement. Tall ceilings, plaster walls and narrow stud bays limit where new ducts can go, so the equipment has to match the duct system that can actually be built. In some homes we keep a working boiler for heat and add small-duct high-velocity cooling through closets and the attic. In others, the existing ducts are sound and only need sealing before a new furnace and AC go in.
Away from the historic core, the post-war and newer neighborhoods toward the bypass have conventional forced-air systems. Many run gas furnaces on Atmos Energy lines, while others use heat pumps on Kentucky Utilities or Inter-County Energy power, especially out in Boyle County.
What a Danville furnace and AC replacement usually costs
These are typical 2026 ranges for a full gas furnace and central air replacement on a single-family Danville home with usable ductwork.
- Home size and load. A room-by-room load calculation sets the tonnage. Older houses with drafty windows and tall ceilings often need a different size than the old unit on the pad.
- Efficiency and staging. Single-stage equipment costs less up front. Two-stage and variable-speed systems cost more but run quieter and pull more moisture out of humid summer air.
- Duct condition. Leaky or undersized ducts in a crawlspace raise the price because they need sealing, resizing or partial replacement to work with new equipment.
- Venting changes. Moving from an older furnace vented through a masonry chimney to a high-efficiency model means new PVC venting and a condensate drain.
- Refrigerant line set. New A2L refrigerant systems often need a new or flushed line set, particularly when the old lines ran through a finished wall or tight crawlspace.
The written price for your home comes after we look at the system, measure the house and inspect the ducts. Nothing is ordered until you approve it. Compare typical prices for every service.
Signs a Danville system is ready to be replaced
Age alone does not decide it. These are the signs that tell us a system is nearing the end in Boyle County homes.
Repeat repairs in two seasons
If the same system needed major parts last summer and again this winter, the next failure is usually close behind. We add up the repair history with you.
Rust in the heat exchanger area
Rust flakes or soot near the burners can point to a cracked heat exchanger. That is a carbon monoxide concern and often ends the life of an older furnace.
Rooms that never even out
When upstairs bedrooms in a Foursquare stay several degrees off no matter the setting, the issue is often the design, not just the equipment.
Rising bills on steady rates
A heat pump or AC that loses efficiency draws more power each year. Comparing a few winters of bills on the same rate shows the trend.
R-22 refrigerant on the label
Older air conditioners using R-22 are costly to recharge. A leak on one of these is usually the point where replacement makes more sense than repair.
How a Danville replacement project runs from first visit to startup
Most replacements take one to two days of installation once the equipment is chosen and on hand.
Measure the house
We measure rooms, windows and insulation levels for a load calculation, and photograph the existing equipment, venting and electrical.
Inspect the ducts
We check duct size, leakage and return air paths in the crawlspace, basement or attic, since new equipment can only perform as well as the ducts allow.
Walk through options
You get a written price for each option, from a straight furnace and AC swap to a heat pump or dual fuel pairing, with the tradeoffs spelled out.
Install and protect the house
On install day we cover floors, remove the old equipment, set the new units, and connect gas, power, venting, drain and refrigerant lines.
Start up and measure
We charge the system, measure airflow and temperature split, test the gas side for carbon monoxide, then set up the thermostat with you.
What Danville homes call us for
HVAC System Replacement
Many Danville homes run furnace and AC pairs well past fifteen years, and a planned replacement avoids buying in a rush during a heat wave.
High-Velocity Central Air
Historic houses on East Main and Lexington Avenue rarely have room for full-size ducts, and small-duct systems fit through closets.
Furnace Repair
Atmos Energy gas furnaces are the main heat source in town, and ignition and pressure switch faults lead the winter calls.
Boiler Repair
Some older Danville homes still heat with boilers and radiators, which need their own parts, pressure checks and attention.
Heat Pump Installation
Homes on the edge of town and in rural Boyle County often have no gas line, making a heat pump the practical choice.

Danville heating and cooling questions
Can a historic Danville house get central air without tearing out plaster?
Usually, yes. Small-duct high-velocity systems run flexible tubing through closets, attics and floor cavities, ending at small round outlets. Ductless mini splits are another option for individual rooms. We look at the attic, basement and closet layout first, then show you which approach disturbs the least original material in your home.
Is a heat pump a good fit for a Danville home on Atmos gas?
It can be. A dual fuel system pairs a heat pump with a gas furnace, so the heat pump handles mild weather and the furnace takes over on the coldest nights. If your gas furnace and AC are both aging, this setup is worth comparing against a straight furnace and AC replacement. We price both so you can compare.
How long does a full system replacement take in Danville?
Once you choose the equipment and it is on hand, most installs take one to two days. Jobs that include new venting, duct changes or a high-velocity system in an older house can run longer. Call (859) 377-8167 and we can set up the first measuring visit, which is where the timeline gets pinned down.
