Aurora Weather and HVAC Load
In a normal year, Aurora racks up 5,836 heating and 675 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Aurora put in far more hours than the air conditioner. A normal year brings 172 nights at or below freezing and 47 days over 90°F. Snowfall averages about 49 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.
| Heating degree days / year | 5,836 |
|---|---|

| Average low / high | 34.7°F / 66.8°F |
Aurora Housing Stock
Census figures put the median build year in Aurora at 1985, so a typical house here has about 41 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 63.3% of occupied homes, roughly 91,000 households. With a median household income of $84,320 and a median home value of $444,500, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 20 hail days and 24 days with damaging thunderstorm winds in Arapahoe 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. Arapahoe County also had 5 tornado days in that period.

Colorado Permits, Efficiency Rules and Rebates
Colorado 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 Aurora generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Colorado 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.
- Ask your gas or oil company about rebates on condensing boilers.
- A combi boiler frees up space and replaces your water heater.
