Bloomington Weather and HVAC Load
NOAA's 1991-2020 climate normals put Bloomington at 5,281 heating degree days and 1,068 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Bloomington put in far more hours than the air conditioner. A normal year brings 109 nights at or below freezing and 21 days over 90°F. Snowfall averages about 18 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.

Bloomington Housing Stock
The median Bloomington home dates to 1984, according to the Census ACS. That makes the typical house about 42 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 35.1% of occupied homes, roughly 12,000 households. With a median household income of $48,918 and a median home value of $289,700, local labor rates come out below the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 11 hail days and 22 days with damaging thunderstorm winds in Monroe County. The largest hail reported was 2.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Monroe County also had 4 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. Expect the contractor to pull a mechanical permit for a replacement job in Bloomington. 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
- 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.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
