Terre Haute Weather and HVAC Load
In a normal year, Terre Haute racks up 4,892 heating and 1,473 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Terre Haute put in far more hours than the air conditioner. Count on roughly 116 nights below 32°F and 47 afternoons past 90°F in a typical year. Snowfall averages about 15 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Terre Haute Housing Stock
Census figures put the median build year in Terre Haute at 1958, so a typical house here has about 68 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Terre Haute has roughly 12,000 owner-occupied homes, or 53.5% of households. With a median household income of $41,960 and a median home value of $109,500, local labor rates come out below the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 24 days with damaging thunderstorm winds in Vigo County. The largest hail reported was 1.75 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.
When Replacement Makes Sense
- An old R-22 AC paired with an aging furnace
- Both units keep needing repairs
- Some rooms are uncomfortable, and the energy bills are high
What Moves the Price
- Permits and electrical work
- Efficiency ratings: SEER2, AFUE and HSPF2
- Duct repair or replacement
- Equipment sized to the house and climate
- Thermostat and zoning upgrades
- Furnace plus AC, or heat pump plus air handler
We lowered the national figures about 8% for Terre Haute 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
- New, matched heating and cooling equipment
- Duct connections and sealing
- Startup, testing and warranty registration
- Removing the old equipment
- A load calculation and system design
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. Expect the contractor to pull a mechanical permit for a replacement job in Terre Haute. If a bidder suggests skipping it, move on. Also ask for a Indiana license or registration number and proof of insurance. 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
- Get one quote for a heat pump system and one for a furnace plus AC.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
