Lafayette Weather and HVAC Load
NOAA's 1991-2020 climate normals put Lafayette at 5,823 heating degree days and 883 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Lafayette put in far more hours than the air conditioner. Count on roughly 116 nights below 32°F and 20 afternoons past 90°F in a typical year. Snowfall averages about 21 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Homes here have a median value of $157,600 and households a median income of $52,946. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Tippecanoe County show 3 hail days and 19 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Tippecanoe County also had 2 tornado days in that period.

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 Lafayette 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 a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
