Heat Pump Panel Check — Maryland

In Maryland, a whole-home air-source heat pump typically costs $5,000–$14,000 installed, depending on home size, system type, and contractor. Cold-climate models for zones like Zone 4A cost more but deliver lower operating costs. Combined rebates of up to $1,300 (state programs) can offset a significant portion of installed cost.

Maryland's HEEHRA program has not yet launched but is expected to open. The federal HEAR program (~$8,000 income-qualified heat pump rebate) has NOT yet launched in Maryland as of June 2026 — the Maryland Energy Administration holds only conditional DOE approval and is in contractor procurement. BGE and EmPOWER Maryland utility rebates are the available-now incentives. IRA 25C expired Dec 31, 2025. Check your state energy office for updates. Note: the federal IRA 25C tax credit expired December 31, 2025 and is not available for new 2026 installations.

Maryland falls in IECC 2021 Zone 4A — Mixed-Humid. Typical winter design temperatures are 10°F to 22°F. Cold-climate heat pumps (rated to -13°F) are recommended for primary heating. Standard units lose efficiency below 20°F. Sizing requires a Manual J load calculation — but as a rough rule, allow 20–30 BTU/h per square foot for older homes in Maryland.

Not necessarily. Most 200A panels in Maryland have headroom for a heat pump under the NEC 220.82 Optional Method — which accounts for diversity of loads rather than peak simultaneous demand. A 100A panel is more likely to require an upgrade, especially if you also have an EV charger or electric range.
