Raleigh Weather and HVAC Load
In a normal year, Raleigh racks up 3,165 heating and 1,778 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Raleigh. That balance is a big reason heat pumps and dual-fuel systems sell well in North Carolina. A normal year brings 57 nights at or below freezing and 47 days over 90°F. Snowfall averages about 5 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 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 | 3,165 |
|---|---|
| Cooling degree days / year | 1,778 |
| Nights at or below 32°F | 57 |
| Days above 90°F | 47 |
| Average low / high | 50.5°F / 71.7°F |
Raleigh Housing Stock
Census figures put the median build year in Raleigh at 1996, so a typical house here has about 30 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Raleigh has roughly 101,000 owner-occupied homes, or 51.2% of households. Homes here have a median value of $377,800 and households a median income of $82,424. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Wake County show 17 hail days and 81 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.25 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. Wake County also had 2 tornado days in that period.

North Carolina Permits, Efficiency Rules and Rebates
North Carolina is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Equipment replacements in Raleigh generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their North Carolina 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
