Greenwood Weather and HVAC Load
In a normal year, Greenwood racks up 5,703 heating and 946 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Greenwood put in far more hours than the air conditioner. Count on roughly 120 nights below 32°F and 13 afternoons past 90°F in a typical year. Snowfall averages about 17 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 5,703 |
|---|---|
| Cooling degree days / year | 946 |
| Nights at or below 32°F | 120 |
| Days above 90°F | 13 |
| Average low / high | 42.4°F / 61.3°F |
Greenwood Housing Stock
Census figures put the median build year in Greenwood at 1995, so a typical house here has about 31 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Greenwood has roughly 16,000 owner-occupied homes, or 60.9% of households. With a median household income of $78,765 and a median home value of $248,700, local labor rates come out near the national middle in our model.
NOAA storm reports for Johnson County show 4 hail days and 18 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Johnson County also had 3 tornado days in that period.
When Replacement Makes Sense
- A repair quote runs past a third of the cost of a new unit
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
What Moves the Price
- Permit and inspection fees, which the local building department sets
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Condition of the existing ductwork and any changes it needs
- BTU size, which should come from a Manual J load calculation
We raised the national figures about 12% for Greenwood using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- The permit and the manufacturer warranty registration
- Removing and hauling away the old furnace
- The new furnace, filter rack and thermostat wiring
- Gas line and vent connections
- Combustion and safety tests
Indiana Permits, Efficiency Rules and Rebates
Indiana falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Greenwood generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Indiana license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask for the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Look up utility rebates on 95%+ AFUE units before you buy.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.

Furnace Replacement Questions from Greenwood Homeowners
How much is furnace replacement in Greenwood?
Plan on $3,600 to $8,700, with most jobs near $6,400. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement in Greenwood?
Between late spring and early fall. Greenwood averages 120 freezing nights a year, and heating calls spike from November through February.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
