Chesapeake Weather and HVAC Load
In a normal year, Chesapeake racks up 2,809 heating and 2,130 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Chesapeake. That balance is a big reason heat pumps and dual-fuel systems sell well in Virginia. A normal year brings 52 nights at or below freezing and 66 days over 90°F. Snowfall averages about 6 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 | 2,809 |
|---|---|
| Cooling degree days / year | 2,130 |
| Nights at or below 32°F | 52 |
| Days above 90°F | 66 |
| Average low / high | 52.4°F / 73.7°F |
Chesapeake Housing Stock
Half the homes in Chesapeake were built before 1989 (Census ACS median), so the typical house is about 37 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 68,000 households here own their home, 73.8% of the occupied total. With a median household income of $94,189 and a median home value of $359,100, local labor rates come out above the national middle in our model.
Chesapeake city had 3 hail days and 22 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

Virginia Permits, Efficiency Rules and Rebates
Virginia 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 Chesapeake generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Virginia 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
- Get one quote for a heat pump system and one for a furnace plus AC.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Replacing both pieces at once usually costs less than two separate jobs a few years apart.
