Peoria Weather and HVAC Load
NOAA's 1991-2020 climate normals put Peoria at 5,613 heating degree days and 1,157 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Peoria put in far more hours than the air conditioner. A normal year brings 118 nights at or below freezing and 23 days over 90°F. Snowfall averages about 26 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 | 5,613 |

Peoria Housing Stock
Half the homes in Peoria were built before 1966 (Census ACS median), so the typical house is about 60 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. About 28,000 households here own their home, 58.2% of the occupied total. With a median household income of $58,716 and a median home value of $149,500, local labor rates come out below the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 20 hail days and 26 days with damaging thunderstorm winds in Peoria 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. Peoria County also had 3 tornado days in that period.

Illinois Permits, Efficiency Rules and Rebates
Illinois 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 Peoria generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Illinois 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
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
