Dover Housing Stock
Half the homes in Dover were built before 1985 (Census ACS median), so the typical house is about 41 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 7,300 households here own their home, 47% of the occupied total. Homes here have a median value of $248,500 and households a median income of $58,336. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 3 hail days and 34 days with damaging thunderstorm winds in Kent County. The largest hail reported was 1 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. Kent County also had 2 tornado days in that period.

Delaware Licensing and Efficiency Rules
Delaware 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). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Delaware the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
