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. The AC still runs every summer, but it works far fewer hours than the furnace does. A normal year brings 109 nights at or below freezing and 21 days over 90°F. Snowfall averages about 18 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

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.
When It Makes Sense
- It still runs on R-22 refrigerant
- The house can't reach the thermostat setting on hot afternoons
- It has had more than one refrigerant leak
- Summer electric bills keep going up
What Moves the Price
- Whether the coil and line set also need replacing
- Tonnage, based on house size and local climate
- SEER2 rating and whether the compressor is single-stage or variable-speed
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- Electrical work such as a new disconnect, breaker or wiring
For Bloomington we lowered the national figures about 13%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- Refrigerant charge and a leak test
- Removing the old condenser and coil
- Startup, an airflow check and warranty registration
- The electrical disconnect and wiring
- The new condenser, coil and, if needed, line set
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
- Ask for a Manual J calculation. "Same size as the old one" isn't sizing.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
- Fall and early spring installs often come with better pricing and shorter waits.
