Should you repair or replace?
Ask each bidder for the heat pump capacity at 17°F and 5°F, the auxiliary heat size and lockout temperature, and whether ductwork needs changes for the higher airflow heat pumps require.
What should a good service visit include?
- Room-by-room load calculation
- Evaluate ducts, electrical service, and outdoor placement
- Compare ducted, ductless, and hybrid configurations
- Commission defrost, staging, and aux heat lockout
What is different about Wilmington properties?
Older 100-amp services are common in Wilmington rowhouses and postwar homes, so electrical capacity is often the first constraint. Historic districts may have rules about where outdoor units can go; confirm before finalizing the design.
What efficiency is required for a new system in Delaware?
Delaware is in the U.S. Department of Energy’s Southeast region. Since January 1, 2023, new split air conditioners under 45,000 BTU/h must be at least 14.3 SEER2 (13.8 SEER2 at 45,000 BTU/h and above), and split heat pumps must be at least 14.3 SEER2 and 7.5 HSPF2.
| Equipment (split system) | Minimum in Delaware (Southeast region) |
|---|---|
| Air conditioner under 45,000 BTU/h | 14.3 SEER2 |
| Air conditioner 45,000 BTU/h and up | 13.8 SEER2 |
| Heat pump (all sizes) | 14.3 SEER2 and 7.5 HSPF2 |

Higher-rated equipment can lower operating costs, but correct sizing, duct condition, and installation quality affect real-world efficiency as much as the label. Energize Delaware rebates generally require higher efficiency tiers; confirm the model qualifies before signing.
Which brands and equipment are covered?
Ducted heat pumps: Carrier, Bryant, Trane, American Standard, Lennox, Daikin, Goodman, Rheem, and York. Cold-climate and ductless options: Mitsubishi Electric, Fujitsu, Daikin, and LG. Ask for published capacity at 17°F and 5°F for the exact model. See all brands and common issues.
Ask the responding provider for identity, applicable Delaware license information, a written diagnosis or scope, total price, and warranty terms.
